The device delivers a 15 ns pin-to-pin propagation delay and operates from a single 4.75V to 5.25V supply, providing approximately 5,000 usable gates for glue-logic, bus-interface, and state-machine designs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks with a programmable interconnect matrix. Architecturally, CPLDs sit between simple SPLDs/PALs and larger FPGAs in the programmable logic hierarchy: like SPLDs they offer instant-on, deterministic, flash- or EPROM-backed configuration, but like FPGAs they integrate hundreds to thousands of gates with predictable timing. The MAX 7000S family uses Altera's second-generation MAX architecture with EEPROM-based configuration cells, eliminating the need for an external boot PROM and enabling in-system programmability (ISP) via JTAG. Key features of the EPM7256SQC208-15 include 256 macrocells distributed across 16 LABs, a global clock network, programmable power management with pin-controlled turbo-bit disable for low-power standby, JTAG-compliant boundary-scan (IEEE 1149.1), and four pin-compatible speed grades (7, 10, 12, 15 ns). The 'C' in the part number designates the commercial 0C to +70C operating range; '15' denotes the 15 ns pin-to-pin delay. Typical applications include bus-bridging logic between microprocessors and peripherals, address decoding and chip-select generation in embedded systems, glue logic in telecommunications and networking equipment, industrial control state machines, and replacement of multiple discrete 74-series logic ICs. The 164 user I/Os comfortably support wide data and address buses plus control signals for legacy parallel interfaces. When designing with the EPM7256SQC208-15, ensure 5V tolerance compatibility for the I/O banks, provide proper decoupling on VCCINT/VCCIO pins, and use the Altera MAX+PLUS II or Quartus II design tools for synthesis, fitting, and JTAG programming. Designers migrating to lower-density footprints should consider the speed-grade variants (EPM7256SQC208-10 for 10 ns, EPM7256SQC208-7 for 7 ns) which are pin-compatible drop-in upgrades.

Its 208-pin PQFP package provides ample I/O for bus-interface, glue-logic, and state-machine applications. The MAX 7000S architecture uses a programmable interconnect array (PIA) to route signals between logic array blocks (LABs), each containing 16 macrocells. This architecture delivers predictable timing independent of routing, a critical advantage over SRAM-based FPGAs in deterministic control applications. The EEPROM configuration retains logic after power-down, eliminating external configuration memory. Typical applications include PCI bus interfaces, ISA-to-PCI bridges, DMA controllers, state machines for industrial automation, and glue logic replacing discrete 74-series TTL. The 164 I/O pins and 256 macrocells make it suitable for medium-complexity designs that would otherwise require dozens of discrete logic packages. When designing with this device, ensure the 5 V supply is well-decoupled with 0.1 uF ceramic capacitors on every VCC pin, and reserve JTAG pins (TCK, TMS, TDI, TDO) for programming and boundary-scan testing. The 15 ns speed grade limits maximum system clock frequency; for higher-speed designs, consider the -10 or -7 speed grades.

Typical applications include bus-interface bridging (e.g., 8/16/32-bit address decoding), power-up sequencing for multi-rail systems, peripheral glue logic in telecom line cards, industrial PLC I/O expansion, and replacement of multiple 74-series TTL/CMOS logic gates in cost-down board designs. The 212 user I/Os also suit LED-driver multiplexing and high-density state-machine controllers. When designing with the EPM7512BFI256-7, ensure the 0.8 mm-pitch BGA is mounted with appropriate PCB fabrication tolerances and that all unused I/Os are left floating or tied per the datasheet recommendation. Decoupling should follow Altera's reference design: 0.1 µF + 10 µF bulk capacitors placed within 100 mil of each supply pin. For migration, the SameFrame pin-out allows drop-in to EPM7256BFI256-7 (256 macrocells) and to EPM7192BFI256-7 (192 macrocells) on the same 256-ball footprint.

What is a CPLD? A Complex Programmable Logic Device is a non-volatile programmable logic device that combines multiple PAL-like macrocell arrays with a central interconnect matrix. CPLDs sit between simple SPLDs and FPGAs in the programmable-logic hierarchy, providing fast, deterministic pin-to-pin timing (no boot time), instant-on operation, and EEPROM- or flash-based configuration that retains the bitstream across power cycles. The MAX 7000B family specifically is built on a 2.5 V CMOS EEPROM Multiple Array Matrix (MAX) architecture and was designed as a glue-logic replacement for multiple 74-series TTL parts. Key features of the EPM7512BQC208-10 include 32 Logic Array Blocks (LABs) of 16 macrocells each, four pin-to-pin output enable signals, in-system programmability through a JTAG-compliant IEEE Std. 1149.1 interface, and a commercial operating temperature grade of 0 to +70 degrees C. The device operates from an internal 2.5 V core supply (2.375 V to 2.625 V) and is supported by the legacy Altera MAX+PLUS II and Quartus II design software. Architecturally, the MAX 7000B device uses a second-generation MAX architecture with a programmable interconnect array (PIA) that routes signals between LABs. Each macrocell contains a programmable AND/OR array, a flip-flop, and configurable I/O architecture supporting JTAG boundary-scan testing, which simplifies board-level test in production. The -10 speed grade places this part at the slower end of the MAX 7000B range, trading off fmax for reduced cost and easier timing closure in glue-logic applications. Typical applications include bus-interface bridging, address decoding, state-machine control, peripheral glue logic, industrial I/O expansion, and legacy 5 V/3.3 V system interfacing where the MAX 7000B I/O tolerance is required. The 176 user I/O count is generous for replacing many discrete 74LS/74HC packages with a single device. When designing, note that the EPM7512BQC208-10 is part of the mature MAX 7000B line: many MAX 7000B variants are now NRND or EOL, so check the latest lifecycle status before committing to a new design. The 208-pin PQFP package requires careful PCB layout, with thermal and high-speed signal-integrity considerations; XAIPART can cross-reference compatible MAX 7000B speed grades (e.g., -7, -10, -12, -15) that share this PQFP-208 footprint.

EPM9320ALI84-10N - 320-Macrocell 10ns MAX 9000 CPLD | Altera
The Altera EPM9320ALI84-10N is a high-density, in-system-programmable Complex Programmable Logic Device (CPLD) from the MAX 9000 family, delivering 320 macrocells, 20 Logic Array Blocks (LABs), and 6,000 to 12,000 usable gates in a 5.0-V CMOS EEPROM-based architecture. Housed in an 84-pin PLCC (Plastic Leaded Chip Carrier) package with J-bend terminals on a 1.270 mm pitch, this device offers pin-to-pin delays as fast as 10 ns and counter speeds up to 144 MHz, making it suitable for high-performance glue-logic, bus-interface, and state-machine applications. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocells with a central interconnect matrix. In the system hierarchy, the CPLD sits between simple SPLDs (PAL/GAL) and FPGAs: it offers deterministic 10 ns timing, instant-on EEPROM configuration, and high I/O count, but lacks the fine-grained LUT fabric of an FPGA. The MAX 9000 family implements Altera's third-generation Multiple Array MatriX (MAX) architecture, which groups macrocells into LABs joined by a programmable interconnect array (PIA), enabling predictable timing and efficient state-machine implementation. Key features of the EPM9320ALI84-10N include 56 user I/O pins, separate VCCINT (5.0 V) and VCCIO pins for output-driver voltage selection (3.3 V or 5.0 V), and built-in IEEE Std. 1149.1 JTAG interface for in-system programmability (ISP). The device supports TTL-compatible inputs at 5.0-V VCCINT and offers multi-voltage I/O for mixed-voltage designs. Programmable power reduction modes lower quiescent current during standby, while the -10 speed grade delivers the fastest pin-to-pin delay in the MAX 9320 die family. The MAX architecture uses EEPROM configuration memory, which provides non-volatile storage and infinite re-programmability without external boot devices. The 320 macrocells are split into 20 LABs of 16 macrocells each, with each macrocell containing a programmable AND/OR array, a flip-flop, and configurable I/O control. This organization is optimized for wide combinatorial and registered logic functions typical of address decoding, bus arbitration, and asynchronous state-machine designs. Typical applications include high-performance bus-interface and address decoding in microprocessor systems, peripheral glue logic in telecom and networking equipment, industrial control and instrumentation logic, and replacement of multiple discrete TTL/CMOS MSI parts on legacy PCBs. The 84-pin PLCC package and through-hole-compatible socket footprint also make the EPM9320ALI84-10N a common choice for legacy industrial and military designs that require hand-reworkability. When designing with the EPM9320ALI84-10N, ensure that VCCINT is always tied to 5.0 V, while VCCIO can be set to 3.3 V or 5.0 V depending on the I/O rail. Use the JTAG interface for in-system re-programmability and boundary-scan testing, and observe the maximum I/O current ratings per bank to avoid output-buffer overheating. The -10 speed grade has the highest dynamic ICC; for lower-power designs, consider the slower -12 or -15 grades in the same MAX 9320 die family. This page synthesizes the manufacturer datasheet, current distributor stock levels, drop-in alternatives drawn from the same MAX 9000 family and competitor CPLD lines, and practical PCB design guidance not found in a single manufacturer document - information gain targeted at engineers maintaining or upgrading legacy 5 V MAX 9000 designs.
EPM9320AR1208-10 - MAX 9000 EPLD, 1208-Pin PGA, 10ns | Intel / Altera
The Intel / Altera (formerly Altera Corporation) EPM9320AR1208-10 is a member of the MAX 9000 Programmable Logic Device Family, a high-density, in-system programmable Erasable Programmable Logic Device (EPLD) fabricated in 0.7 µm CMOS EEPROM technology. The MAX 9000 family combines the look-up-table (LUT) architecture used in FPGAs with the macrocell architecture of classic EPLDs, yielding a logic density of 6,000 usable gates in the base device, packaged here in a 1208-pin ceramic/ceramic-equivalent Pin Grid Array (PGA) denoted by package code 'AR1208'. The speed grade '-10' designates a 10 ns pin-to-pin logic delay through the Logic Array Blocks (LABs) and Interconnect, supporting system clocks up to approximately 100 MHz in pipelined designs. A Programmable Logic Device (PLD) is a generic term that historically encompassed simple PAL/GAL devices, complex EPLDs like the MAX 9000 family, and modern FPGAs. The MAX 9000 sits in the middle of this hierarchy as a 'Complex PLD' (CPLD) - large enough to replace dozens of 7400-series SSI/MSI parts, small enough to retain the non-volatility, deterministic timing, and instant-on characteristics of classic PLDs. Within the broader taxonomy: programmable logic device -> EPLD -> complex EPLD (CPLD) -> MAX family -> MAX 9000 series. Key architectural features of the EPM9320AR1208-10 include multiple Logic Array Blocks interconnected by the Programmable Interconnect Array (PIA), a global routing structure that delivers predictable timing with fixed propagation delays. The 'A' suffix indicates the ceramic PGA package variant; the 'R' suffix indicates the device is supplied in tape-and-reel orientation suitable for legacy through-hole assembly flows. The device supports in-system programmability via the IEEE 1149.1 (JTAG) boundary-scan chain, allowing configuration updates without removing the part from the board, and offers JTAG-based read-back of device state for production test. Typical applications for the EPM9320AR1208-10 include legacy telecom interface glue logic, industrial control state machines, bus-address decoding, peripheral integration in VMEbus and Multibus II systems, and pin-compatible drop-in replacement of older discrete TTL/CMOS logic arrays. The MAX 9000 family is widely cited in applications notes for replacing 7400-series glue logic, custom state machines, and address decoders in long-lifecycle defense, aerospace, and industrial systems. When designing with this part, engineers should note that the MAX 9000 family has been in production since the mid-1990s and is approaching end-of-life; second-source qualification and last-time-buy planning are recommended. Programming is performed via the Altera ByteBlaster or compatible JTAG programmer using MAX+PLUS II or Quartus II development software. Surface-mount and lead-free variants exist in the MAX 7000 and MAX V families for new designs.
