Functional Description
The CY7C1381D/CY7C1381F/CY7C1383D/CY7C1383F is a 3.3 V, 512 K x 36 and 1 M x 18 synchronous flow through SRAMs, designed to interface with high speed microprocessors with minimum glue logic[1]. Maximum access delay from clock rise is 6.5 ns (133 MHz version). A 2-bit on-chip counter captures the first address in a burst and increments the address automatically for the rest of the burst access. All synchronous inputs are gated by registers controlled by a positive edge triggered clock input (CLK). The synchronous inputs include all addresses, all data inputs, address pipelining chip enable (CE1), depth-expansion chip enables (CE2 and CE3 [2]), burst control inputs (ADSC, ADSP, and ADV), write enables (BWx, and BWE), and global write (GW). Asynchronous inputs include the output enable (OE) and the ZZ pin. The CY7C1381D/CY7C1381F/CY7C1383D/CY7C1383F allows interleaved or linear burst sequences, selected by the MODE input pin. A HIGH selects an interleaved burst sequence, while a LOW selects a linear burst sequence. Burst accesses can be initiated with the processor address strobe (ADSP) or the cache controller address strobe (ADSC) inputs. Address advancement is controlled by the address advancement (ADV) input. Addresses and chip enables are registered at rising edge of clock when address strobe processor (ADSP) or address strobe controller (ADSC) are active. Subsequent burst addresses can be internally generated as controlled by the advance pin (ADV). CY7C1381D/CY7C1381F/CY7C1383D/CY7C1383F operates from a +3.3 V core power supply while all outputs operate with a +2.5 V or +3.3 V supply. All inputs and outputs are JEDEC-standard and JESD8-5-compatible.

Name DQs I/O I/O Synchronous Description Bidirectional data I/O lines. As inputs, they feed into an on-chip data register that is triggered by the rising edge of CLK. As outputs, they deliver the data contained in the memory location specified by the addresses presented during the previous clock rise of the read cycle. The direction of the pins is controlled by OE. When OE is asserted LOW, the pins behave as outputs. When HIGH, DQs and DQPX are placed in a tristate condition.The outputs are automatically tristated during the data portion of a write sequence, during the first clock when emerging from a deselected state, and when the device is deselected, regardless of the state of OE. Bidirectional data parity I/O lines. Functionally, these signals are identical to DQs. During write sequences, DQPX is controlled by BWX correspondingly. Selects burst order. When tied to GND selects linear burst sequence. When tied to VDD or left floating selects interleaved burst sequence. This is a strap pin and must remain static during device operation. Mode pin has an internal pull-up. Power supply inputs to the core of the device.

This pin can be connected to ground or can be left floating. Accesses can be initiated with the processor address strobe (ADSP) or the controller address strobe (ADSC). Address advancement through the burst sequence is controlled by the ADV input. A two-bit on-chip wraparound burst counter captures the first address in a burst sequence and automatically increments the address for the rest of the burst access. Byte write operations are qualified with the byte write enable (BWE) and byte write select (BWX) inputs. A global write enable (GW) overrides all byte write inputs and writes data to all four bytes. All writes are simplified with on-chip synchronous self-timed write circuitry.

Functional Overview
All synchronous inputs pass through input registers controlled by the rising edge of the clock. Maximum access delay from the clock rise (t CDV) is 6.5 ns (133 MHz device). CY7C1381D/CY7C1381F/CY7C1383D/CY7C1383F supports secondary cache in systems using a linear or interleaved burst sequence. The interleaved burst order supports Pentium and i486 processors. The linear burst sequence is suited for processors that use a linear burst sequence. The burst order is user selectable, and is determined by sampling the MODE input.

CY7C1381D/CY7C1381F CY7C1383D/CY7C1383F
Three synchronous chip selects (CE1, CE2, CE3 [5]) and an asynchronous output enable (OE) provide for easy bank selection and output tristate control. ADSP is ignored if CE1 is HIGH. the data lines are tristated when a write cycle is detected, regardless of the state of OE. Burst Sequences CY7C1381D/CY7C1381F/CY7C1383D/CY7C1383F provides an on-chip two-bit wraparound burst counter inside the SRAM. The burst counter is fed by A[1:0], and can follow either a linear or interleaved burst order. The burst order is determined by the state of the MODE input. A LOW on MODE selects a linear burst sequence. A HIGH on MODE selects an interleaved burst order. Leaving MODE unconnected causes the device to default to a interleaved burst sequence.
Single Read Accesses
A single read access is initiated when the following conditions are satisfied at clock rise: (1) CE1, CE2, and CE3 [5] are all asserted active, and (2) ADSP or ADSC is asserted LOW (if the access is initiated by ADSC, the write inputs must be deasserted during this first cycle). The address presented to the address inputs is latched into the address register and the burst counter and/or control logic, and later presented to the memory core. If the OE input is asserted LOW, the requested data is available at the data outputs with a maximum to tCDV after clock rise. ADSP is ignored if CE1 is HIGH.
Sleep Mode
The ZZ input pin is an asynchronous input. Asserting ZZ places the SRAM in a power conservation sleep mode. Two clock cycles are required to enter into or exit from this sleep mode. While in this mode, data integrity is guaranteed. Accesses pending when entering the sleep mode are not considered valid nor is the completion of the operation guaranteed. The device must be deselected prior to entering the sleep mode. CE1, CE2, CE3 [5], ADSP, and ADSC must remain inactive for the duration of tZZREC after the ZZ input returns LOW. Table 1.

Single Write Accesses Initiated by ADSP
This access is initiated when the following conditions are satisfied at clock rise: (1) CE1, CE2, CE3 [5] are all asserted active, and (2) ADSP is asserted LOW. The addresses presented are loaded into the address register and the burst inputs (GW, BWE, and BWX) are ignored during this first clock cycle. If the write inputs are asserted active (see Truth Table for Read/Write on page 13 for appropriate states that indicate a write) on the next clock rise, the appropriate data is latched and written into the device. Byte writes are allowed. All I/O are tristated during a byte write. As this is a common I/O device, the asynchronous OE input signal must be deasserted and the I/O must be tristated prior to the presentation of data to DQs. As a safety precaution, the data lines are tristated when a write cycle is detected, regardless of the state of OE.
Single Write Accesses Initiated by ADSC
This write access is initiated when the following conditions are satisfied at clock rise: (1) CE1, CE2, and CE3 [5] are all asserted active, (2) ADSC is asserted LOW, (3) ADSP is deasserted HIGH, and (4) the write input signals (GW, BWE, and BWX) indicate a write access. ADSC is ignored if ADSP is active LOW. The addresses presented are loaded into the address register and the burst counter, the control logic, or both, and delivered to the memory core The information presented to DQ[A:D] is written into the specified address location. Byte writes are allowed. All I/O are tristated when a write is detected, even a byte write. Because this is a common I/O device, the asynchronous OE input signal must be deasserted and the I/O must be tristated prior to the presentation of data to DQs. As a safety precaution,

The SRAM always initiates a read cycle when ADSP is asserted, regardless of the state of GW, BWE, or BWX. Writes may occur only on subsequent clocks after the ADSP or with the assertion of ADSC. As a result, OE must be driven HIGH prior to the start of the write cycle to allow the outputs to tristate. OE is a don't care for the remainder of the write cycle. 10. OE is asynchronous and is not sampled with the clock rise. It is masked internally during write cycles. During a read cycle all data bits are tristate when OE is inactive or when the device is deselected, and all data bits behave as output when OE is active (LOW).

CY7C1381D/CY7C1381F CY7C1383D/CY7C1383F
IEEE 1149.1 Serial Boundary Scan (JTAG)
The CY7C1381D/CY7C1381F/CY7C1383D/CY7C1383F incorporates a serial boundary scan test access port (TAP).This part is fully compliant with 1149.1. The TAP operates using JEDEC-standard 3.3 V or 2.5 V I/O logic levels. CY7C1381D/CY7C1381F/CY7C1383D/CY7C1383F contains a TAP controller, instruction register, boundary scan register, bypass register, and ID register. Test Data-In (TDI) The TDI ball is used to serially input information into the registers and can be connected to the input of any of the registers. The register between TDI and TDO is chosen by the instruction that is loaded into the TAP instruction register. TDI is internally pulled up and can be unconnected if the TAP is unused in an application. TDI is connected to the most significant bit (MSB) of any register. (See TAP Controller Block Diagram.) Test Data-Out (TDO) The TDO output ball is used to serially clock data-out from the registers. The output is active depending upon the current state of the TAP state machine. The output changes on the falling edge of TCK. TDO is connected to the least significant bit (LSB) of any register. (See TAP Controller State Diagram.)
Disabling the JTAG Feature
It is possible to operate the SRAM without using the JTAG feature. To disable the TAP controller, TCK must be tied LOW (VSS) to prevent clocking of the device. TDI and TMS are internally pulled up and may be unconnected. They may alternately be connected to VDD through a pull-up resistor. TDO may be left unconnected. At power up, the device comes up in a reset state, which does not interfere with the operation of the device.

TCK TMS TAP CONTROLLER
Performing a TAP Reset
A reset is performed by forcing TMS HIGH (VDD) for five rising edges of TCK. This reset does not affect the operation of the SRAM and may be performed while the SRAM is operating. At power up, the TAP is reset internally to ensure that TDO comes up in a high Z state.
The 0 or 1 next to each state represents the value of TMS at the rising edge of TCK.
TAP Registers
Registers are connected between the TDI and TDO balls and allow data to be scanned in and out of the SRAM test circuitry. Only one register can be selected at a time through the instruction registers. Data is serially loaded into the TDI ball on the rising edge of TCK. Data is output on the TDO ball on the falling edge of TCK. Instruction Register Three-bit instructions can be serially loaded into the instruction register. This register is loaded when it is placed between the TDI and TDO balls as shown in the TAP Controller Block Diagram. Upon power up, the instruction register is loaded with the IDCODE instruction. It is also loaded with the IDCODE instruction if the controller is placed in a reset state as described in the previous section.
Test Access Port (TAP)
Test Clock (TCK) The test clock is used only with the TAP controller. All inputs are captured on the rising edge of TCK. All outputs are driven from the falling edge of TCK. Test Mode Select (TMS) The TMS input is used to give commands to the TAP controller and is sampled on the rising edge of TCK. This pin may be left unconnected if the TAP is not used. The ball is pulled up internally, resulting in a logic HIGH level.

When the TAP controller is in the Capture-IR state, the two least significant bits are loaded with a binary `01' pattern to allow for fault isolation of the board level serial test path. Bypass Register To save time when serially shifting data through registers, it is sometimes advantageous to skip certain chips. The bypass register is a single-bit register that can be placed between the TDI and TDO balls. This allows data to be shifted through the SRAM with minimal delay. The bypass register is set LOW (VSS) when the BYPASS instruction is executed. Boundary Scan Register The boundary scan register is connected to all the input and bidirectional balls on the SRAM. The boundary scan register is loaded with the contents of the RAM input and output ring when the TAP controller is in the Capture-DR state and is then placed between the TDI and TDO balls when the controller is moved to the Shift-DR state. The EXTEST, SAMPLE/PRELOAD, and SAMPLE Z instructions can be used to capture the contents of the input and output ring. The boundary scan order tables show the order in which the bits are connected. Each bit corresponds to one of the bumps on the SRAM package. The MSB of the register is connected to TDI, and the LSB is connected to TDO. Identification (ID) Register The ID register is loaded with a vendor-specific 32-bit code during the Capture-DR state when the IDCODE command is loaded in the instruction register. The IDCODE is hardwired into the SRAM and can be shifted out when the TAP controller is in the Shift-DR state. The ID register has a vendor code and other information described in Identification Register Definitions on page 18. the IDCODE to be shifted out of the device when the TAP controller enters the Shift-DR state. The IDCODE instruction is loaded into the instruction register upon power up or whenever the TAP controller is given a test logic reset state. SAMPLE Z The SAMPLE Z instruction causes the boundary scan register to be connected between the TDI and TDO balls when the TAP controller is in a Shift-DR state. The SAMPLE Z command places all SRAM outputs into a high Z state. SAMPLE/PRELOAD SAMPLE/PRELOAD is a 1149.1 mandatory instruction. When the SAMPLE/PRELOAD instructions are loaded into the instruction register and the TAP controller is in the Capture-DR state, a snapshot of data on the inputs and output pins is captured in the boundary scan register. The user must be aware that the TAP controller clock can only operate at a frequency up to 20 MHz, while the SRAM clock operates more than an order of magnitude faster. Because there is a large difference in the clock frequencies, it is possible that during the Capture-DR state, an input or output undergoes a transition. The TAP may then try to capture a signal while in transition (metastable state). This does not harm the device, but there is no guarantee as to the value that is captured. Repeatable results may not be possible. To guarantee that the boundary scan register captures the correct value of a signal, the SRAM signal must be stabilized long enough to meet the TAP controller's capture setup plus hold times (tCS and tCH). The SRAM clock input might not be captured correctly if there is no way in a design to stop (or slow) the clock during a SAMPLE/PRELOAD instruction. If this is an issue, it is still possible to capture all other signals and simply ignore the value of the CK and CK captured in the boundary scan register. After the data is captured, it is possible to shift out the data by putting the TAP into the Shift-DR state. This places the boundary scan register between the TDI and TDO pins. PRELOAD allows an initial data pattern to be placed at the latched parallel outputs of the boundary scan register cells prior to the selection of another boundary scan test operation. The shifting of data for the SAMPLE and PRELOAD phases can occur concurrently when required; that is, while data captured is shifted out, the preloaded data is shifted in. BYPASS When the BYPASS instruction is loaded in the instruction register and the TAP is placed in a Shift-DR state, the bypass register is placed between the TDI and TDO balls. The advantage of the BYPASS instruction is that it shortens the boundary scan path when multiple devices are connected together on a board. EXTEST Output Bus Tri-State IEEE standard 1149.1 mandates that the TAP controller be able to put the output bus into a tristate mode. The boundary scan register has a special bit located at bit #85 (for 119-BGA package) or bit #89 (for 165-FBGA package). When this scan cell, called the "extest output bus tristate," is latched into the preload register during the Update-DR state in Page 15 of 34
TAP Instruction Set
Overview Eight different instructions are possible with the three bit instruction register. All combinations are listed in Identification Codes on page 18. Three of these instructions are listed as RESERVED and must not be used. The other five instructions are described in detail below. Instructions are loaded into the TAP controller during the Shift-IR state, when the instruction register is placed between TDI and TDO. During this state, instructions are shifted through the instruction register through the TDI and TDO balls. To execute the instruction when it is shifted in, the TAP controller needs to be moved into the Update-IR state. EXTEST The EXTEST instruction enables the preloaded data to be driven out through the system output pins. This instruction also selects the boundary scan register to be connected for serial access between the TDI and TDO in the Shift-DR controller state. IDCODE The IDCODE instruction causes a vendor-specific 32-bit code to be loaded into the instruction register. It also places the instruction register between the TDI and TDO balls and allows

the TAP controller, it directly controls the state of the output (Q-bus) pins, when the EXTEST is entered as the current instruction. When HIGH, it enables the output buffers to drive the output bus. When LOW, this bit places the output bus into a high Z condition. This bit can be set by entering the SAMPLE/PRELOAD or EXTEST command, and then shifting the desired bit into that cell, during the Shift-DR state. During Update-DR, the value loaded into that shift-register cell latches into the preload register. When the EXTEST instruction is entered, this bit directly controls the output Q-bus pins. Note that this bit is preset HIGH to enable the output when the device is powered up, and also when the TAP controller is in the Test-Logic-Reset state.

Notes 24. Timing reference level is 1.5 V when VDDQ = 3.3 V and is 1.25 V when VDDQ = 2.5 V. 25. Test conditions shown in (a) of AC Test Loads unless otherwise noted. 26. This part has a voltage regulator internally; tPOWER is the time that the power needs to be supplied above VDD(minimum) initially, before a read or write operation can be initiated. 27. tCHZ, tCLZ,tOELZ, and tOEHZ are specified with AC test conditions shown in part (b) of "AC Test Loads and Waveforms" on page 22. Transition is measured 200 mV from steady-state voltage. 28. At any given voltage and temperature, tOEHZ is less than tOELZ and tCHZ is less than tCLZ to eliminate bus contention between SRAMs when sharing the same data bus. These specifications do not imply a bus contention condition, but reflect parameters guaranteed over worst case user conditions. Device is designed to achieve high Z prior to low Z under the same system condition. 29. This parameter is sampled and not 100% tested.
