With CF High, a short access time after CE and OE are enabled, data is available on the PROM DATA (D0) pin that is connected to the FPGA DIN pin. New data is available a short access time after each rising clock edge. The FPGA generates the appropriate number of clock pulses to complete the configuration. When the FPGA is in Slave Serial mode, the PROM and the FPGA are both clocked by an external clock source, or optionally, for the XCFxxP PROM only, the PROM can be used to drive the FPGA's configuration clock. The XCFxxP version of the Platform Flash PROM also supports Master SelectMAP and Slave SelectMAP (or Slave Parallel) FPGA configuration modes. When the FPGA is in Master SelectMAP mode, the FPGA generates a configuration clock that drives the PROM. When the FPGA is in Slave SelectMAP Mode, either an external oscillator generates the configuration clock that drives the PROM and the FPGA, or optionally, the XCFxxP PROM can be used to drive the FPGA's configuration clock. With BUSY Low and CF High, after CE and OE are enabled, data is available on the PROMs DATA (D0-D7) pins. New data is available a DS123 (v2.17) October 26, 2009 Product Specification short access time after each rising clock edge. The data is clocked into the FPGA on the following rising edge of the CCLK. A free-running oscillator can be used in the Slave Parallel/Slave SelectMAP mode. The XCFxxP version of the Platform Flash PROM provides additional advanced features. A built-in data decompressor supports utilizing compressed PROM files, and design revisioning allows multiple design revisions to be stored on a single PROM or stored across several PROMs. For design revisioning, external pins or internal control bits are used to select the active design revision. Multiple Platform Flash PROM devices can be cascaded to support the larger configuration files required when targeting larger FPGA devices or targeting multiple FPGAs daisy chained together. When utilizing the advanced features for the XCFxxP Platform Flash PROM, such as design revisioning, programming files which span cascaded PROM devices can only be created for cascaded chains containing only XCFxxP PROMs. If the advanced XCFxxP features are not enabled, then the cascaded chain can include both XCFxxP and XCFxxS PROMs. www.xilinx.com 2 R Platform Flash In-System Programmable Configuration PROMs instruction sequence. The iMPACT software also outputs serial vector format (SVF) files for use with any tools that accept SVF format, including automatic test equipment. During in-system programming, the CEO output is driven High. All other outputs are held in a high-impedance state or held at clamp levels during in-system programming. All non-JTAG input pins are ignored during in-system programming, including CLK, CE, CF, OE/RESET, BUSY, EN_EXT_SEL, and REV_SEL[1:0]. In-system programming is fully supported across the recommended operating voltage and temperature ranges. Embedded, in-system programming reference designs, such as XAPP058, Xilinx In-System Programming Using an Embedded Microcontroller, are available on the Xilinx web page for PROM Programming and Data Storage Application Notes. See UG161, Platform Flash PROM User Guide, for an advanced update methodology that uses the Design Revisioning feature in the Platform Flash XCFxxP PROMs. See UG161, Platform Flash PROM User Guide, for detailed guidelines on PROM-to-FPGA configuration hardware connections, for software usage, for a reference list of Xilinx FPGAs, and for the respective compatible Platform Flash PROMs. Table 2 lists the Platform Flash PROMs and their capacities.

Reprogramming requires an erase followed by a program operation. A verify operation is recommended after the program operation to validate the correct transfer of data from the programmer source to the Platform Flash PROM. Several programming solutions are available. OE/RESET The 1/2/4 Mb XCFxxS Platform Flash PROMs in-system programming algorithm results in issuance of an internal device reset that causes OE/RESET to pulse Low. External Programming In-System Programming In-System Programmable PROMs can be programmed individually, or two or more can be daisy-chained together and programmed in-system via the standard 4-pin JTAG protocol as shown in Figure 3. X-Ref Target - Figure 3 In traditional manufacturing environments, third-party device programmers can program Platform Flash PROMs with an initial memory image before the PROMs are assembled onto boards. Contact a preferred third-party programmer vendor for Platform Flash PROM support information. A sample list of third-party programmer vendors with Platform Flash PROM support is available on the Xilinx web page for Third-Party Programmer Device Support. See UG161, Platform Flash PROM User Guide, for the PROM data file format required for programmers. Pre-programmed PROMs can be assembled onto boards using the typical soldering process guidelines in UG112, Device Package User Guide. A pre-programmed PROM's memory image can be updated after board assembly using an in-system programming solution.

DS123 (v2.17) October 26, 2009 Product Specification www.xilinx.com 3 R Platform Flash In-System Programmable Configuration PROMs Design Security The Xilinx in-system programmable Platform Flash PROM devices incorporate advanced data security features to fully protect the FPGA programming data against unauthorized reading via JTAG. The XCFxxP PROMs can also be programmed to prevent inadvertent writing via JTAG. Table 3 and Table 4 show the security settings available for the XCFxxS PROM and XCFxxP PROM, respectively. Write Protection The XCFxxP PROM device also allows the user to write protect (or lock) a particular design revision or PROM option settings. Write protection helps to prevent an inadvertent JTAG instruction from modifying an area by write protecting the area and by locking the erase instruction. The writeprotection setting can be cleared by erasing the protected area. However, an XSC_UNLOCK instruction must first be issued to the XCFxxP PROM to unlock the ISC_ERASE instruction. Refer to the XCFxxP PROM BSDL file for the XSC_UNLOCK and ISC_ERASE instructions. Caution! The iMPACT software always issues a XSC_UNLOCK when performing an Erase operation on an XCFxxP PROM and, thus, always unlocks the write protection. Read Protection The read protect security bit can be set by the user to prevent the internal programming pattern from being read or copied via JTAG. Read protection does not prevent write operations. For the XCFxxS PROM, the read protect security bit is set for the entire device, and resetting the read protect security bit requires erasing the entire device. For the XCFxxP PROM the read protect security bit can be set for individual design revisions, and resetting the read protect bit requires erasing the particular design revision.

A Test Access Port (TAP) and registers are provided to support all required Boundary-Scan instructions, as well as many of the optional instructions specified by IEEE Std. 1149.1. In addition, the JTAG interface is used to implement in-system programming (ISP) to facilitate configuration, erasure, and verification operations on the Platform Flash PROM device. Table 5 lists the required and optional Boundary-Scan instructions supported in the Platform Flash PROMs. Refer to the IEEE Std. 1149.1 specification for a complete description of Boundary-Scan architecture and the required and optional instructions. Caution! The XCFxxP JTAG TAP pause states are not fully compliant with the JTAG 1149.1 specification. If a temporary pause of a JTAG shift operation is required, then stop the JTAG TCK clock and maintain the JTAG TAP within the JTAG Shift-IR or Shift-DR TAP state. Do not transition the XCFxxP JTAG TAP through the JTAG Pause-IR or Pause-DR TAP state to temporarily pause a JTAG shift operation.

For more information see "Initiating FPGA Configuration," page 10. Instruction Register The Instruction Register (IR) for the Platform Flash PROM is connected between TDI and TDO during an instruction scan sequence. In preparation for an instruction scan sequence, the instruction register is parallel loaded with a fixed instruction capture pattern. This pattern is shifted out onto TDO (LSB first), while an instruction is shifted into the instruction register from TDI. XCFxxP Instruction Register (16 bits wide) The Instruction Register (IR) for the XCFxxP PROM is sixteen bits wide and is connected between TDI and TDO during an instruction scan sequence. The detailed composition of the instruction capture pattern is illustrated in Table 7, page 6. The instruction capture pattern shifted out of the XCFxxP device includes IR[15:0]. IR[15:9] are reserved bits and are set to a logic 0. The ISC Error field, IR[8:7], contains a 10 when an ISC operation is a success; otherwise a 01 when an In-System Configuration (ISC) operation fails. The Erase/Program (ER/PROG) Error field, IR[6:5], contains a 10 when an erase or program operation is a success; otherwise a 01 when an erase or program operation fails. The Erase/Program (ER/PROG) Status field, IR[4], contains a logic 0 when the device is busy performing an erase or programming operation; otherwise, it contains a logic 1. The ISC Status field, IR[3], contains logic 1 if the device is currently in In-System Configuration (ISC) mode; otherwise, it contains logic 0. The DONE field, IR[2], contains logic 1 if the sampled design revision has been successfully programmed; otherwise, a logic 0 indicates incomplete programming. The remaining bits IR[1:0] are set to 01 as defined by IEEE Std. 1149.1. XCFxxS Instruction Register (8 bits wide) The Instruction Register (IR) for the XCFxxS PROM is eight bits wide and is connected between TDI and TDO during an instruction scan sequence. The detailed composition of the instruction capture pattern is illustrated in Table 6, page 6. The instruction capture pattern shifted out of the XCFxxS device includes IR[7:0]. IR[7:5] are reserved bits and are set to a logic 0. The ISC Status field, IR[4], contains logic 1 if the device is currently in In-System Configuration (ISC) mode; otherwise, it contains logic 0. The Security field, IR[3], contains logic 1 if the device has been programmed with the security option turned on; otherwise, it contains logic 0. IR[2] is unused, and is set to '0'. The remaining bits IR[1:0] are set to '01' as defined by IEEE Std. 1149.1.

Each output pin on the Platform Flash PROM has two register stages which contribute to the Boundary-Scan register, while each input pin has only one register stage. The bidirectional pins have a total of three register stages which contribute to the Boundary-Scan register. For each output pin, the register stage nearest to TDI controls and observes the output state, and the second stage closest to TDO controls and observes the High-Z enable state of the output pin. For each input pin, a single register stage controls and observes the input state of the pin. The bidirectional pin combines the three bits, the input stage bit is first, followed by the output stage bit and finally the output enable stage bit. The output enable stage bit is closest to TDO. See Table 12, page 24 and Table 13, page 26 for the Boundary-Scan bit order for all connected device pins, or see the appropriate BSDL file for the complete Boundary-Scan bit order description under the "attribute BOUNDARY_REGISTER" section in the BSDL file. The bit assigned to Boundary-Scan cell 0 is the LSB in the BoundaryScan register, and is the register bit closest to TDO. The LSB of the IDCODE register is always read as logic 1 as defined by IEEE Std. 1149.1. Table 8: IDCODES Assigned to Platform Flash PROMs Device XCF01S XCF02S XCF04S XCF08P XCF16P XCF32P Notes: 1. The IDCODE (1) (hex) USERCODE Register The USERCODE instruction gives access to a 32-bit user programmable scratch pad typically used to supply information about the device's programmed contents. By using the USERCODE instruction, a user-programmable identification code can be shifted out for examination. This code is loaded into the USERCODE register during programming of the Platform Flash PROM. If the device is blank or was not loaded during programming, the USERCODE register contains FFFFFFFFh. Identification Registers IDCODE Register The IDCODE is a fixed, vendor-assigned value that is used to electrically identify the manufacturer and type of the device being addressed. The IDCODE register is 32 bits wide. The IDCODE register can be shifted out for examination by using the IDCODE instruction. The IDCODE is available to any other system component via JTAG. Table 8 lists the IDCODE register values for the Platform Flash PROMs. The IDCODE register has the following binary format: vvvv:ffff:ffff:aaaa:aaaa:cccc:cccc:ccc1 Customer Code Register For the XCFxxP Platform Flash PROM, in addition to the USERCODE, a unique 32-byte Customer Code can be assigned to each design revision enabled for the PROM. The Customer Code is set during programming, and is typically used to supply information about the design revision contents. A private JTAG instruction is required to read the Customer Code. If the PROM is blank, or the Customer Code for the selected design revision was not loaded during programming, or if the particular design revision is erased, the Customer Code contains all ones. where v = the die version number f = the PROM family code a = the specific Platform Flash PROM product ID c = the Xilinx manufacturer's ID DS123 (v2.17) October 26, 2009 Product Specification www.xilinx.com 6 R Platform Flash In-System Programmable Configuration PROMs Platform Flash PROM TAP Characteristics The Platform Flash PROM family performs both in-system programming and IEEE 1149.1 Boundary-Scan (JTAG) testing via a single 4-wire Test Access Port (TAP). This simplifies system designs and allows standard Automatic Test Equipment to perform both functions. The AC characteristics of the Platform Flash PROM TAP are described as follows.

The internal oscillator can be enabled when programming the PROM, and the oscillator can be set to either the default frequency or to a slower frequency. Refer to the "XCFxxP Decompression and Clock Options" chapter of UG161, Platform Flash PROM User Guide, for internal oscillator recommendations. SelectMAP (parallel) configuration modes are supported for FPGA configuration when using a XCFxxP PROM programmed with a compressed bitstream. Compression rates vary depending on several factors, including the target device family and the target design contents. The decompression option is enabled during the PROM programming sequence. The PROM decompresses the stored data before driving both clock and data onto the FPGA's configuration interface. If Decompression is enabled, then the Platform Flash clock output pin (CLKOUT) must be used as the clock signal for the configuration interface, driving the target FPGA's configuration clock input pin (CCLK). Either the PROM's CLK input pin or the internal oscillator must be selected as the source for CLKOUT. Any target FPGA connected to the PROM must operate as slave in the configuration chain, with the configuration mode set to Slave Serial mode or Slave SelectMap (parallel) mode. When decompression is enabled, the CLKOUT signal becomes a controlled clock output with a reduced maximum frequency. When decompressed data is not ready, the CLKOUT pin is put into a high-Z state and must be pulled High externally to provide a known state. The BUSY input is automatically disabled when decompression is enabled. See the "Decompression Setups" section in the Platform Flash PROM User Guide for setup details. CLKOUT The 8/16/32 Mb XCFxxP Platform Flash PROMs include the programmable option to enable the CLKOUT signal which allows the PROM to provide a source synchronous clock aligned to the data on the configuration interface. The CLKOUT signal is derived from one of two clock sources: the CLK input pin or the internal oscillator. The input clock source is selected during the PROM programming sequence. Output data is available on the rising edge of CLKOUT. The CLKOUT signal is enabled during programming, and is active when CE is Low and OE/RESET is High. On CE rising edge transition, if OE/RESET is High and the PROM terminal count has not been reached, then CLKOUT remains active for an additional eights clock cycles before being disabled. On a OE/RESET falling edge transition, CLKOUT is immediately disabled. When disabled, the CLKOUT pin is put into a high-impedance state and should be pulled High externally to provide a known state. When cascading Platform Flash PROMs with CLKOUT enabled, after completing it's data transfer, the first PROM disables CLKOUT and drives the CEO pin enabling the next PROM in the PROM chain. The next PROM begins driving the CLKOUT signal once that PROM is enabled and data is available for transfer. During high-speed parallel configuration without compression, the FPGA drives the BUSY signal on the configuration interface. When BUSY is asserted High, the PROMs internal address counter stops incrementing, and the current data value is held on the data outputs. While BUSY is High, the PROM continues driving the CLKOUT signal to the FPGA, clocking the FPGA's configuration logic. When the FPGA deasserts BUSY, indicating that it is ready to receive additional configuration data, the PROM begins driving new data onto the configuration interface. Design Revisioning Design Revisioning allows the user to create up to four unique design revisions on a single PROM or stored across multiple cascaded PROMs. Design Revisioning is supported for the 8/16/32 Mb XCFxxP Platform Flash PROMs in both serial and parallel modes. Design Revisioning can be used with compressed PROM files, and also when the CLKOUT feature is enabled. The PROM programming files along with the revision information files (.cfi) are created using the iMPACT software. The .cfi file is required to enable design revision programming in iMPACT. A single design revision is composed of from 1 to n 8 Mb memory blocks. If a single design revision contains less than 8 Mb of data, then the remaining space is padded with all ones. A larger design revision can span several 8 Mb memory blocks, and any space remaining in the last 8 Mb memory block is padded with all ones. * A single 32 Mb PROM contains four 8 Mb memory blocks, and can therefore store up to four separate design revisions: one 32 Mb design revision, two 16 Mb design revisions, three 8 Mb design revisions, four 8 Mb design revisions, and so on. Decompression The 8/16/32 Mb XCFxxP Platform Flash PROMs include a built-in data decompressor compatible with Xilinx advanced compression technology. Compressed Platform Flash PROM files are created from the target FPGA bitstream(s) using the iMPACT software. Only Slave Serial and Slave DS123 (v2.17) October 26, 2009 Product Specification www.xilinx.com 8 R Platform Flash In-System Programmable Configuration PROMs * Because of the 8 Mb minimum size requirement for each revision, a single 16 Mb PROM can only store up to two separate design revisions: one 16 Mb design revision, one 8 Mb design revision, or two 8 Mb design revisions. A single 8 Mb PROM can store only one 8 Mb design revision. * Larger design revisions can be split over several cascaded PROMs. For example, two 32 Mb PROMs can store up to four separate design revisions: one 64 Mb design revision, two 32 Mb design revisions, three 16 Mb design revisions, four 16 Mb design revisions, and so on. When cascading one 16 Mb PROM and one 8 Mb PROM, there are 24 Mb of available space, and therefore up to three separate design revisions can be stored: one 24 Mb design revision, two 8 Mb design revisions, or three 8 Mb design revisions. See Figure 5 for a few basic examples of how multiple revisions can be stored. The design revision partitioning is handled automatically during file generation in iMPACT. During the PROM file creation, each design revision is assigned a revision number: Revision 0 = '00' Revision 1 = '01' Revision 2 = '10' Revision 3 = '11' After programming the Platform Flash PROM with a set of design revisions, a particular design revision can be selected using the external REV_SEL[1:0] pins or using the internal programmable design revision control bits. The EN_EXT_SEL pin determines if the external pins or internal bits are used to select the design revision. When EN_EXT_SEL is Low, design revision selection is controlled by the external Revision Select pins, REV_SEL[1:0]. When EN_EXT_SEL is High, design revision selection is controlled by the internal programmable Revision Select control bits. During power up, the design revision selection inputs (pins or control bits) are sampled internally. After power up, the design revision selection inputs are sampled again when any of the following events occur: * * * * On the rising edge of CE. On the falling edge of OE/RESET (when CE is Low). On the rising edge of CF (when CE is Low). When reconfiguration is initiated by using the JTAG CONFIG instruction. The data from the selected design revision is then presented on the FPGA configuration interface.

The XCFxxP PROM samples the current design revision selection from the external REV_SEL pins or the internal programmable Revision Select bits on the rising edge of CF. When the JTAG CONFIG command is executed, the XCFxxP samples the new design revision selection before initiating the FPGA configuration sequence. When using the XCFxxP Platform Flash PROM without design revisioning, if the CF pin is not connected to the FPGA PROGRAM_B pin, then the XCFxxP CF pin must be tied High. Following the FPGA's power-on sequence or the assertion of the PROGRAM_B pin, the FPGA's configuration memory is cleared, the configuration mode is selected, and the FPGA is ready to accept a new configuration bitstream. The FPGA's PROGRAM_B pin can be controlled by an external source, or alternatively, the Platform Flash PROMs incorporate a CF pin that can be tied to the FPGA's PROGRAM_B pin. Executing the CONFIG instruction through JTAG pulses the CF output Low once for 300-500 ns, resetting the FPGA and initiating configuration. The iMPACT software can issue the JTAG CONFIG command to initiate FPGA configuration by setting the "Load FPGA" option. DS123 (v2.17) October 26, 2009 Product Specification www.xilinx.com 10 R Platform Flash In-System Programmable Configuration PROMs Reset and Power-On Reset Activation At power up, the device requires the VCCINT power supply to monotonically rise to the nominal operating voltage within the specified VCCINT rise time. If the power supply cannot meet this requirement, then the device might not perform power-on reset properly. During the power-up sequence, OE/RESET is held Low by the PROM. Once the required supplies have reached their respective POR (Power On Reset) thresholds, the OE/RESET release is delayed (TOER minimum) to allow more margin for the power supplies to stabilize before initiating configuration. The OE/RESET pin is connected to an external 4.7 k pull-up resistor and also to the target FPGA's INIT pin. For systems utilizing slowrising power supplies, an additional power monitoring circuit can be used to delay the target configuration until the system power reaches minimum operating voltages by holding the OE/RESET pin Low. When OE/RESET is released, the FPGA's INIT pin is pulled High allowing the FPGA's configuration sequence to begin. If the power drops X-Ref Target - Figure 6 below the power-down threshold (VCCPD), the PROM resets and OE/RESET is again held Low until the after the POR threshold is reached. OE/RESET polarity is not programmable. These power-up requirements are shown graphically in Figure 6. For a fully powered Platform Flash PROM, a reset occurs whenever OE/RESET is asserted (Low) or CE is deasserted (High). The address counter is reset, CEO is driven High, and the remaining outputs are placed in a high-impedance state. Note: 1. The XCFxxS PROM only requires VCCINT to rise above its POR threshold before releasing OE/RESET. 2. The XCFxxP PROM requires both VCCINT to rise above its POR threshold and for VCCO to reach the recommended operating voltage level before releasing OE/RESET. VCCINT Recommended Operating Range Delay or Restart Configuration 200 s ramp 50 ms ramp VCCPOR VCCPD A slow-ramping VCCINT supply may still be below the minimum operating voltage when OE/RESET is released. In this case, the configuration sequence must be delayed until both VCCINT and VCCO have reached their recommended operating conditions. TIME (ms) TRST ds123_21_103103 TOER TOER Figure 6: Platform Flash PROM Power-Up Requirements I/O Input Voltage Tolerance and Power Sequencing The I/Os on each re-programmable Platform Flash PROM are fully 3.3V-tolerant. This allows 3V CMOS signals to connect directly to the inputs without damage. The core power supply (VCCINT), JTAG pin power supply (VCCJ), output power supply (VCCO), and external 3V CMOS I/O signals can be applied in any order. Additionally, for the XCFxxS PROM only, when VCCO is supplied at 2.5V or 3.3V and VCCINT is supplied at 3.3V, the I/Os are 5V-tolerant. This allows 5V CMOS signals to connect directly to the inputs on a powered XCFxxS PROM without damage. Failure to power the PROM correctly while supplying a 5V input signal can result in damage to the XCFxxS device. DS123 (v2.17) October 26, 2009 Product Specification www.xilinx.com 11 R Platform Flash In-System Programmable Configuration PROMs Standby Mode The PROM enters a low-power standby mode whenever CE is deasserted (High). In standby mode, the address counter is reset, CEO is driven High, and the remaining outputs are placed in a high-impedance state regardless of the state of the OE/RESET input. For the device to remain in the low-power standby mode, the JTAG pins TMS, TDI, and TDO must not be pulled Low, and TCK must be stopped (High or Low). When using the FPGA DONE signal to drive the PROM CE pin High to reduce standby power after configuration, an external pull-up resistor should be used. Typically a 330 Table 10: Truth Table for XCFxxS PROM Control Inputs Control Inputs OE/RESET High Low X (1) Notes: 1. 2. X = don't care. TC = Terminal Count = highest address value. pull-up resistor is used, but refer to the appropriate FPGA data sheet for the recommended DONE pin pull-up value. If the DONE circuit is connected to an LED to indicate FPGA configuration is complete, and is also connected to the PROM CE pin to enable low-power standby mode, then an external buffer should be used to drive the LED circuit to ensure valid transitions on the PROM's CE pin. If low-power standby mode is not required for the PROM, then the CE pin should be connected to ground.

The delay before CLKOUT is enabled increases if decompression is enabled. 9. Slower CLK frequency option might be required to meet the FPGA data sheet setup time. 10. When decompression is enabled, the CLKOUT signal becomes a controlled clock output. When decompressed data is available, CLKOUT toggles at 1/2 the source clock frequency (either 1/2 the selected internal clock frequency or 1/2 the external CLK input frequency). When decompressed data is not available, the CLKOUT pin is parked High. If CLKOUT is used, then it must be pulled High externally using a 4.7 k pull-up to VCCO. 11. When JTAG CONFIG command is issued, PROM drives CF Low for at least the THCF minimum.
