altera corporation 5 max 7000b programmable logic device data sheet max 7000b devices provide programmable speed/power optimization. speed-critical portions of a design can run at high speed/full power, while the remaining portions run at reduced speed/low power. this speed/power optimization feature enables the designer to configure one or more macrocells to operate up to 50 % lower power while adding only a nominal timing delay. max 7000b devices also provide an option that reduces the slew rate of the output buffers, minimizing noise transients when non-speed-critical signals are switching. the output drivers of all max 7000b devices can be set for 3.3 v, 2.5 v, or 1.8 v and all input pins are 3.3-v, 2.5-v, and 1.8-v tolerant, allowing max 7000b devices to be used in mixed-voltage systems. max 7000b devices are supported by altera development systems, which are integrated packages that offer schematic, text?ncluding vhdl, verilog hdl, and the altera hardware description language (ahdl) and waveform design entry, compilation and logic synthesis, simulation and timing analysis, and device programming. altera software provides edif 2 0 0 and 3 0 0, lpm, vhdl, verilog hdl, and other interfaces for additional design entry and simulation support from other industry- standard pc- and unix-workstation-based eda tools. altera software runs on windows-based pcs, as well as sun sparcstation, and hp 9000 series 700/800 workstations. f for more information on development tools, see the max+plus ii programmable logic development system & software data sheet and the quartus programmable logic development system & software data sheet . functional description the max 7000b architecture includes the following elements: labs macrocells expander product terms (shareable and parallel) pia i/o control blocks the max 7000b architecture includes four dedicated inputs that can be used as general-purpose inputs or as high-speed, global control signals (clock, clear, and two output enable signals) for each macrocell and i/o pin. figure 1 shows the architecture of max 7000b devices.

altera corporation 7 max 7000b programmable logic device data sheet macrocells the max 7000b macrocell can be individually configured for either sequential or combinatorial logic operation. the macrocell consists of three functional blocks: the logic array, the product-term select matrix, and the programmable register. figure 2 shows the max 7000b macrocell. figure 2. max 7000b macrocell combinatorial logic is implemented in the logic array, which provides five product terms per macrocell. the product-term select matrix allocates these product terms for use as either primary logic inputs (to the or and xor gates) to implement combinatorial functions, or as secondary inputs to the macrocell? register preset, clock, and clock enable control functions. two kinds of expander product terms (?xpanders? are available to supplement macrocell logic resources: shareable expanders, which are inverted product terms that are fed back into the logic array parallel expanders, which are product terms borrowed from adjacent macrocells product- te r m select matrix 36 signals from pia 16 expander product terms lab local array parallel logic expanders (from other macrocells) shared logic expanders clear select global clear global clocks clock/ enable select 2 prn clrn d/t q ena register bypass to i/o control block from i/o pin to pia programmable register fast input select vcc
8 altera corporation max 7000b programmable logic device data sheet the altera development system automatically optimizes product-term allocation according to the logic requirements of the design. for registered functions, each macrocell flipflop can be individually programmed to implement d, t, jk, or sr operation with programmable clock control. the flipflop can be bypassed for combinatorial operation. during design entry, the designer specifies the desired flipflop type; the max+plus ii software then selects the most efficient flipflop operation for each registered function to optimize resource utilization. each programmable register can be clocked in three different modes: global clock signal. this mode achieves the fastest clock-to-output performance. global clock signal enabled by an active-high clock enable. a clock enable is generated by a product term. this mode provides an enable on each flipflop while still achieving the fast clock-to-output performance of the global clock. array clock implemented with a product term. in this mode, the flipflop can be clocked by signals from buried macrocells or i/o pins. two global clock signals are available in max 7000b devices. as shown in figure 1 , these global clock signals can be the true or the complement of either of the global clock pins, gclk1 or gclk2 . each register also supports asynchronous preset and clear functions. as shown in figure 2 , the product-term select matrix allocates product terms to control these operations. although the product-term-driven preset and clear from the register are active high, active-low control can be obtained by inverting the signal within the logic array. in addition, each register clear function can be individually driven by the active-low dedicated global clear pin ( gclrn ). upon power-up, each register in a max 7000b device may be set to either a high or low state. this power-up state is specified at design entry. all max 7000b i/o pins have a fast input path to a macrocell register. this dedicated path allows a signal to bypass the pia and combinatorial logic and be clocked to an input d flipflop with an extremely fast input setup time. the input path from the i/o pin to the register has a programmable delay element that can be selected to either guarantee zero hold time or to get the fastest possible set-up time (as fast as 1.0 ns).
altera corporation 9 max 7000b programmable logic device data sheet expander product terms although most logic functions can be implemented with the five product terms available in each macrocell, more complex logic functions require additional product terms. another macrocell can be used to supply the required logic resources. however, the max 7000b architecture also offers both shareable and parallel expander product terms (?xpanders? that provide additional product terms directly to any macrocell in the same lab. these expanders help ensure that logic is synthesized with the fewest possible logic resources to obtain the fastest possible speed. shareable expanders each lab has 16 shareable expanders that can be viewed as a pool of uncommitted single product terms (one from each macrocell) with inverted outputs that feed back into the logic array. each shareable expander can be used and shared by any or all macrocells in the lab to build complex logic functions. a small delay ( t sexp ) is incurred when shareable expanders are used. figure 3 shows how shareable expanders can feed multiple macrocells. figure 3. max 7000b shareable expanders shareable expanders can be shared by any or all macrocells in an lab. macrocell product-term logic product-term select matrix macrocell product-term logic 36 signals from pia 16 shared expanders
10 altera corporation max 7000b programmable logic device data sheet parallel expanders parallel expanders are unused product terms that can be allocated to a neighboring macrocell to implement fast, complex logic functions. parallel expanders allow up to 20 product terms to directly feed the macrocell or logic, with five product terms provided by the macrocell and 15 parallel expanders provided by neighboring macrocells in the lab. the altera compiler can automatically allocate up to three sets of up to five parallel expanders to the macrocells that require additional product terms. each set of five parallel expanders incurs a small, incremental timing delay ( t pexp ). for example, if a macrocell requires 14 product terms, the compiler uses the five dedicated product terms within the macrocell and allocates two sets of parallel expanders; the first set includes five product terms and the second set includes four product terms, increasing the total delay by 2 t pexp . two groups of eight macrocells within each lab (e.g., macrocells 1 through 8, and 9 through 16) form two chains to lend or borrow parallel expanders. a macrocell borrows parallel expanders from lower- numbered macrocells. for example, macrocell 8 can borrow parallel expanders from macrocell 7, from macrocells 7 and 6, or from macrocells 7, 6, and 5. within each group of eight, the lowest-numbered macrocell can only lend parallel expanders and the highest-numbered macrocell can only borrow them. figure 4 shows how parallel expanders can be borrowed from a neighboring macrocell.
altera corporation 11 max 7000b programmable logic device data sheet figure 4. max 7000b parallel expanders unused product terms in a macrocell can be allocated to a neighboring macrocell. programmable interconnect array logic is routed between labs on the pia. this global bus is a programmable path that connects any signal source to any destination on the device. all max 7000b dedicated inputs, i/o pins, and macrocell outputs feed the pia, which makes the signals available throughout the entire device. only the signals required by each lab are actually routed from the pia into the lab. figure 5 shows how the pia signals are routed into the lab. an eeprom cell controls one input to a two-input and gate, which selects a pia signal to drive into the lab. preset clock clear product- te r m select matrix preset clock clear product- te r m select matrix macrocell product- term logic from previous macrocell to next macrocell macrocell product- term logic 36 signals from pia 16 shared expanders
12 altera corporation max 7000b programmable logic device data sheet figure 5. max 7000b pia routing while the routing delays of channel-based routing schemes in masked or field-programmable gate arrays (fpgas) are cumulative, variable, and path-dependent, the max 7000b pia has a predictable delay. the pia makes a design? timing performance easy to predict. i/o control blocks the i/o control block allows each i/o pin to be individually configured for input, output, or bidirectional operation. all i/o pins have a tri-state buffer that is individually controlled by one of the global output enable signals or directly connected to ground or v cc . figure 6 shows the i/o control block for max 7000b devices. the i/o control block has six or ten global output enable signals that are driven by the true or complement of two output enable signals, a subset of the i/o pins, or a subset of the i/o macrocells. to lab pia signals

14 altera corporation max 7000b programmable logic device data sheet sameframe pin-outs max 7000b devices support the sameframe pin-out feature for fineline bga and 0.8-mm ultra fineline bga packages. the sameframe pin-out feature is the arrangement of balls on fineline bga and 0.8-mm ultra fineline bga packages such that the lower-ball-count packages form a subset of the higher-ball-count packages. sameframe pin-outs provide the flexibility to migrate not only from device to device within the same package, but also from one package to another. fineline bga packages are compatible with other fineline bga packages, and 0.8-mm ultra fineline bga packages are compatible with other 0.8-mm ultra fineline bga packages. a given printed circuit board (pcb) layout can support multiple device density/package combinations. for example, a single board layout can support a range of devices from an epm7064b device in a 100-pin fineline bga package to an epm7512b device in a 256-pin fineline bga package. the altera software provides support to design pcbs with sameframe pin-out devices. devices can be defined for present and future use. the altera software generates pin-outs describing how to layout a board to take advantage of this migration (see figure 7 ). figure 7. sameframe pin-out example designed for 256-pin fineline bga package printed circuit board 100-pin fineline bga package (reduced i/o count or logic requirements) 256-pin fineline bga package (increased i/o count or logic requirements) 100-pin fineline bga 256-pin fineline bga
altera corporation 15 max 7000b programmable logic device data sheet in-system programma- bility (isp) max 7000b devices can be programmed in-system via an industry- standard 4-pin ieee std. 1149.1 (jtag) interface. isp offers quick, efficient iterations during design development and debugging cycles. the max 7000b architecture internally generates the high programming voltages required to program eeprom cells, allowing in-system programming with only a single 2.5-v power supply. during in-system programming, the i/o pins are tri-stated and weakly pulled-up to eliminate board conflicts. the pull-up value is nominally 50 k ? . max 7000b devices have an enhanced isp algorithm for faster programming. these devices also offer an isp_done bit that provides safe operation when in-system programming is interrupted. this isp_done bit, which is the last bit programmed, prevents all i/o pins from driving until the bit is programmed. isp simplifies the manufacturing flow by allowing devices to be mounted on a pcb with standard pick-and-place equipment before they are programmed. max 7000b devices can be programmed by downloading the information via in-circuit testers, embedded processors, the altera masterblaster communications cable, and the byteblastermv parallel port download cable. programming the devices after they are placed on the board eliminates lead damage on high-pin-count packages (e.g., qfp packages) due to device handling. max 7000b devices can be reprogrammed after a system has already shipped to the field. for example, product upgrades can be performed in the field via software or modem. in-system programming can be accomplished with either an adaptive or constant algorithm. an adaptive algorithm reads information from the unit and adapts subsequent programming steps to achieve the fastest possible programming time for that unit. a constant algorithm uses a pre-defined (non-adaptive) programming sequence that does not take advantage of adaptive algorithm programming time improvements. some in-circuit testers cannot program using an adaptive algorithm. therefore, a constant algorithm must be used. max 7000b devices can be programmed with either an adaptive or constant (non-adaptive) algorithm. the jam standard test and programming language (stapl), jedec standard jesd-71, can be used to program max 7000b devices with in-circuit testers, pcs, or embedded processors. f for more information on using the jam language, see application note 88 (using the jam language for isp & icr via an embedded processor) and application note 122 (using stapl for isp & icr via an embedded processor) . the isp circuitry in max 7000b devices is compliant with the ieee std. 1532 specification. the ieee std. 1532 is a standard developed to allow concurrent isp between multiple pld vendors.
16 altera corporation max 7000b programmable logic device data sheet programming with external hardware max 7000b devices can be programmed on windows-based pcs with an altera logic programmer card, the master programming unit (mpu), and the appropriate device adapter. the mpu performs continuity checking to ensure adequate electrical contact between the adapter and the device. f for more information, see the altera programming hardware data sheet . the altera software can use text- or waveform-format test vectors created with the altera text editor or waveform editor to test the programmed device. for added design verification, designers can perform functional testing to compare the functional device behavior with the results of simulation. data i/o, bp microsystems, and other programming hardware manufacturers provide programming support for altera devices. for more information, see programming hardware manufacturers . ieee std. 1149.1 (jtag) boundary-scan support max 7000b devices include the jtag boundary-scan test circuitry defined by ieee std. 1149.1. table 4 describes the jtag instructions supported by max 7000b devices. the pin-out tables starting on page 55 of this data sheet show the location of the jtag control pins for each device. if the jtag interface is not required, the jtag pins are available as user i/o pins. table 4. max 7000b jtag instructions jtag instruction description sample/preload allows a snapshot of signals at the device pins to be captured and examined during normal device operation, and permits an initial data pattern output at the device pins. extest allows the external circuitry and board-level interconnections to be tested by forcing a test pattern at the output pins and capturing test results at the input pins. bypass places the 1-bit bypass register between the tdi and tdo pins, which allows the boundary-scan test data to pass synchronously through a selected device to adjacent devices during normal operation. clamp allows the values in the boundary-scan register to determine pin states while placing the 1-bit bypass register between the tdi and tdo pins. idcode selects the idcode register and places it between the tdi and tdo pins, allowing the idcode to be serially shifted out of tdo . usercode selects the 32-bit usercode register and places it between the tdi and tdo pins, allowing the usercode value to be shifted out of tdo . isp instructions these instructions are used when programming max 7000b devices via the jtag ports with the masterblaster or byteblastermv download cable, or using a jam file ( .jam ), jam byte-code file ( .jbc ), or serial vector format file ( .svf ) via an embedded processor or test equipment.
altera corporation 17 max 7000b programmable logic device data sheet the instruction register length of max 7000b devices is ten bits. the max 7000b usercode register length is 32 bits. tables 5 and 6 show the boundary-scan register length and device idcode information for max 7000b devices. notes: (1) the most significant bit (msb) is on the left.

altera corporation 19 max 7000b programmable logic device data sheet programmable speed/power control max 7000b devices offer a power-saving mode that supports low-power operation across user-defined signal paths or the entire device. this feature allows total power dissipation to be reduced by 50 % or more, because most logic applications require only a small fraction of all gates to operate at maximum frequency. the designer can program each individual macrocell in a max 7000b device for either high-speed or low-power operation. as a result, speed- critical paths in the design can run at high speed, while the remaining paths can operate at reduced power. macrocells that run at low power incur a nominal timing delay adder ( t lpa ) for the t lad , t lac , t ic , t acl , t cppw , t en , and t sexp parameters. output con?uration max 7000b device outputs can be programmed to meet a variety of system-level requirements. multivolt i/o interface the max 7000b device architecture supports the multivolt i/o interface feature, which allows max 7000b devices to connect to systems with differing supply voltages. max 7000b devices in all packages can be set for 3.3-v, 2.5-v, or 1.8-v pin operation. these devices have one set of v cc pins for internal operation and input buffers ( vccint ), and another set for i/o output drivers ( vccio ). the vccio pins can be connected to either a 3.3-v, 2.5-v, or 1.8-v power supply, depending on the output requirements. when the vccio pins are connected to a 1.8-v power supply, the output levels are compatible with 1.8-v systems. when the vccio pins are connected to a 2.5-v power supply, the output levels are compatible with 2.5-v systems. when the vccio pins are connected to a 3.3-v power supply, the output high is at 3.3 v and is therefore compatible with 3.3-v or 5.0-v systems. devices operating with v ccio levels of 2.5 v or 1.8 v incur a nominal timing delay adder. table 8 describes the max 7000b multivolt i/o support.
20 altera corporation max 7000b programmable logic device data sheet open-drain output option max 7000b devices provide an optional open-drain (equivalent to open-collector) output for each i/o pin. this open-drain output enables the device to provide system-level control signals (e.g., interrupt and write enable signals) that can be asserted by any of several devices. it can also provide an additional wired- or plane. programmable ground pins each unused i/o pin on max 7000b devices may be used as an additional ground pin. this programmable ground feature does not require the use of the associated macrocell; therefore, the buried macrocell is still available for user logic. slew-rate control the output buffer for each max 7000b i/o pin has an adjustable output slew rate that can be configured for low-noise or high-speed performance. a faster slew rate provides high-speed transitions for high-performance systems. however, these fast transitions may introduce noise transients into the system. a slow slew rate reduces system noise, but adds a nominal delay of 4 to 5 ns. when the configuration cell is turned off, the slew rate is set for low-noise performance. each i/o pin has an individual eeprom bit that controls the slew rate, allowing designers to specify the slew rate on a pin-by-pin basis. the slew rate control affects both the rising and falling edges of the output signal. advanced i/o standard support the max 7000b i/o pins support the following i/o standards: lvttl, lvcmos, 1.8-v i/o, 2.5-v i/o, gtl+, sstl-3 class i and ii, and sstl-2 class i and ii. table 8. max 7000b multivolt i/o support v ccio (v) input signal (v) output signal (v) 1.8 2.5 3.3 5.0 1.8 2.5 3.3 5.0 1.8 vvv v 2.5 vvv v 3.3 vvv vv
altera corporation 21 max 7000b programmable logic device data sheet max 7000b devices contain two i/o banks. both banks support all standards. each i/o bank has its own vccio pins. a single device can support 1.8-v, 2.5-v, and 3.3-v interfaces; each bank can support a different standard independently. within a bank, any one of the terminated standards can be supported. figure 9 shows the arrangement of the max 7000b i/o banks. figure 9. max 7000b i/o banks for various advanced i/o standards table 9 shows which macrocells have pins in each i/o bank. each max 7000b device has two vref pins. each can be set to a separate v ref level. any i/o pin that uses one of the voltage-referenced standards (gtl+, sstl-2, or sstl-3) may use either of the two vref pins. if these pins are not required as vref pins, they may be individually programmed to function as user i/o pins. table 9. macrocell pins contained in each i/o bank device bank 1 bank 2 epm7032b 1-16 17-32 epm7064b 1-32 33-64 epm7128b 1-64 65-128 epm7256b 1-128, 177-181 129-176, 182-256 epm7512b 1-265 266-512 individual power bus programmable i/o banks
22 altera corporation max 7000b programmable logic device data sheet programmable pull-up resistor each max 7000b device i/o pin provides an optional programmable pull-up resistor during user mode. when this feature is enabled for an i/o pin, the pull-up resistor (typically 50 k ? ) weakly holds the output to v ccio level. bus hold each max 7000b device i/o pin provides an optional bus-hold feature. when this feature is enabled for an i/o pin, the bus-hold circuitry weakly holds the signal at its last driven state. by holding the last driven state of the pin until the next input signals is present, the bus-hold feature can eliminate the need to add external pull-up or pull-down resistors to hold a signal level when the bus is tri-stated. the bus-hold circuitry also pulls undriven pins away from the input threshold voltage where noise can cause unintended high-frequency switching. this feature can be selected individually for each i/o pin. the bus-hold output will drive no higher than v ccio to prevent overdriving signals. the propagation delays through the input and output buffers in max 7000b devices are not affected by whether the bus-hold feature is enabled or disabled. the bus-hold circuitry weakly pulls the signal level to the last driven state through a resistor with a nominal resistance (r bh ) of approximately 8.5 k ? . table 10 gives specific sustaining current that will be driven through this resistor and overdrive current that will identify the next driven input level. this information is provided for each vccio voltage level. the bus-hold circuitry is active only during user operation. at power-up, the bus-hold circuit initializes its initial hold value as v cc approaches the recommended operation conditions. when transitioning from isp to user mode with bus hold enabled, the bus-hold circuit captures the value present on the pin at the end of programming. table 10. bus hold parameters parameter conditions vccio level units 1.8 v 2.5 v 3.3 v min max min max min max low sustaining current v in > v il (max) 30 50 70 a high sustaining current v in < v ih (min) 30 50 70 a low overdrive current 0 v < v in < v ccio 200 300 500 a high overdrive current 0 v < v in < v ccio 295 435 680 a

24 altera corporation max 7000b programmable logic device data sheet power sequencing & hot-socketing because max 7000b devices can be used in a mixed-voltage environment, they have been designed specifically to tolerate any possible power-up sequence. the v ccio and v ccint power planes can be powered in any order. signals can be driven into max 7000b devices before and during power- up (and power-down) without damaging the device. additionally, max 7000b devices do not drive out during power-up. once operating conditions are reached, max 7000b devices operate as specified by the user. design security all max 7000b devices contain a programmable security bit that controls access to the data programmed into the device. when this bit is programmed, a design implemented in the device cannot be copied or retrieved. this feature provides a high level of design security, because programmed data within eeprom cells is invisible. the security bit that controls this function, as well as all other programmed data, is reset only when the device is reprogrammed. generic testing max 7000b devices are fully functionally tested. complete testing of each programmable eeprom bit and all internal logic elements ensures 100 % programming yield. ac test measurements are taken under conditions equivalent to those shown in figure 11 . test patterns can be used and then erased during early stages of the production flow. figure 11. max 7000b ac test conditions to test system c1 (includes jig capacitance) device input rise and fall times < 2 ns device output 720 ?
