A CPLD (Complex Programmable Logic Device) is a non-volatile, flash- or EEPROM-based programmable logic device that combines multiple PAL/GAL-like macrocell arrays with a central interconnect matrix. The MAX 7000S family is built on Altera's second-generation MAX architecture with 5.0V in-system programmability (ISP), pin compatibility with the original 5.0V MAX 7000S family, and PCI Local Bus Specification Revision 2.2 compliance for the -10 speed grade. CPLDs occupy the middle ground between simple SPLDs and high-density FPGAs, delivering deterministic timing, instant-on non-volatile configuration, and high I/O count at lower cost-per-logic-block. Key features include 3,200 usable gates, 160 macrocells, 84 user I/Os, 10ns tPD propagation delay, 100MHz maximum operating frequency, and an internal 4.75V to 5.25V supply with 5.0V-tolerant I/O. The device supports JTAG-based IEEE Std. 1149.1 boundary-scan testing and in-system programmability through the JTAG interface, eliminating the need for external programmers. The TQFP-100 surface-mount package provides a compact footprint for space-constrained designs, while the industrial -40C to +85C temperature range (denoted by the 'I' suffix) supports harsh-environment deployment. The EPM7160STI100-10 employs Altera's classic EEPROM cell technology, retaining configuration across power cycles without external boot memory. Its deterministic routing fabric and predictable 10ns delay make it suitable for glue logic, bus interface bridging, and state-machine implementation where timing predictability is critical. The 84 available I/Os support wide bus interfaces and parallel peripheral control. Typical applications include PCI bus interface logic, microprocessor peripheral glue logic, bus arbitration and address decoding, state-machine control in industrial automation, and high-density TTL/CMOS logic integration. The 5V core supply and 5V-tolerant I/Os align with legacy industrial and telecom infrastructure that has not yet migrated to 3.3V. When designing with this device, plan the JTAG chain with proper TCK/TMS/TDI/TDO pull-ups and ensure the VCCIO rail matches the connected logic level. Note that the -10 speed grade supports PCI 2.2 timing.

EPM7160STI100-10N - MAX 7000S CPLD, 160 Macrocells, 100MHz, TQFP-100 | Intel/Altera
The Intel (formerly Altera) EPM7160STI100-10N is a high-density, high-performance EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 7000S family, packaged in a 100-pin TQFP and offering 160 macrocells, 84 user I/Os, and a 10 ns pin-to-pin propagation delay. Built on Altera's second-generation MAX architecture with 3.2K usable gates and 5.0V in-system programmability (ISP), this device targets glue-logic, interface bridging, and bus-decoding applications in industrial and commercial designs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on characteristics of PAL/GAL architectures with the high integration density of FPGAs. Within the broader taxonomy, a CPLD is a sub-category of programmable logic devices (PLDs), sitting above discrete 22V10 GALs in density and below modern low-power FPGAs. The MAX 7000S family sits in Altera's classic mid-density CPLD portfolio and is widely used as the 'glue logic' layer between processors, memories, and peripherals in 5V-tolerant systems. Key differentiating features include a 5.0V core and I/O supply, 3.3V or 5V multi-voltage JTAG-based in-system programmability, 100 MHz internal performance, support for up to 84 user I/Os (some sources cite 104 I/Os for the TQFP-100 variant), and an industrial operating temperature range of -40C to +85C indicated by the 'I' suffix. The 'I' designator additionally implies lead-free assembly, an important differentiator versus the older non-I commercial variant. Architecturally, the EPM7160S pairs EEPROM configuration cells with a Logic Array Block (LAB) interconnect fabric, with macrocells combining programmable AND/OR arrays with configurable flip-flops. The MAX 7000S device supports JTAG-compliant IEEE 1149.1 boundary-scan testing, four user I/O pinout schemes via dedicated pin compatibility with other MAX 7000S density points, and a high-performance input path with a global clock network. Typical applications include address decoding and bus interface bridging in 5V microprocessor systems, peripheral glue-logic replacement for legacy 74-series TTL/CMOS logic, industrial control and instrumentation I/O expansion, power-supply sequencing logic, and JTAG-controlled in-system programmable front-ends. Designers frequently choose the EPM7160STI100-10N as a drop-in for end-of-life 22V10 and similar discrete PLD footprints. When designing with this part, pay particular attention to the 5.0V VCC requirement - the S-suffix variant uses 3.3V core, while the EPM7160S family generally operates at 5V - and ensure the JTAG chain respects IEEE 1149.1 ordering when multiple devices share the same boundary-scan test access port.

EPM7192EGC160-12 - 192-Macrocell MAX 7000 CPLD, 12ns, 160-PGA | Intel
The Intel / Altera EPM7192EGC160-12 is a 192-macrocell, 124-I/O CMOS Complex Programmable Logic Device (CPLD) from the MAX 7000 family, housed in a 160-pin Ceramic Pin Grid Array (CPGA / PGA-160) package with a 12 ns pin-to-pin propagation delay and 5.0 V core supply. The 'E' suffix denotes the enhanced MAX 7000E architecture with in-system programmability (ISP) via the built-in IEEE Std. 1149.1 JTAG interface, and 'GC160' identifies the ceramic pin-grid-array package. What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on programmable logic device built from multiple PAL-like logic array blocks (LABs) joined by a central interconnect matrix. CPLDs sit hierarchically above simple PLDs (PAL/GAL) and below FPGAs, offering deterministic timing, fast I/O, and instant-on behavior with no configuration memory load time. They are widely used as glue logic, bus interfaces, and state-machine controllers. Key features of the EPM7192EGC160-12 include 192 macrocells across 4 logic array blocks (LABs) with 3.75K usable gates, 124 user I/O pins, 12 ns tPD propagation delay, and a 76.9 MHz maximum operating frequency per the manufacturer datasheet. The device operates from a single 5.0 V supply (4.75 V to 5.25 V) and supports 5.0 V in-system programmability through the JTAG-compliant IEEE 1149.1 boundary-scan test (BST) interface. The MAX 7000 family supports PCI Local Bus Specification Revision 2.2 timing compatibility in -4 to -10 speed grades. The MAX 7000 architecture combines EEPROM configuration memory (non-volatile) with a classic product-term / macrocell structure, delivering zero standby power for the configuration and deterministic 12 ns combinational delay regardless of how the design routes through the interconnect. This makes the EPM7192EGC160-12 especially attractive for legacy industrial designs that need robust, repeatable timing rather than the absolute logic density of an FPGA. Typical applications include industrial glue logic and bus-interface bridging, telecom backplane control, PCI bus interface glue, address decoding and DMA control in legacy embedded systems, and motor-control I/O expansion. Designers also use the EPM7192E in production ASIC prototyping where instant-on, non-volatile behavior is required. A key design consideration is the 160-pin PGA footprint: although it shares a pin count with some MAX 7000 variants in PQFP packages, the ceramic PGA is socket-friendly and well-suited for legacy / through-hole backplane designs, but it requires a different PCB land pattern than the PQFP / TQFP / QFP variants of the same die. Designers migrating between package options should verify the footprint before reassigning the BOM.

Key features include 192 macrocells, 36 user I/O pins, 4 dedicated inputs, in-system programmability (ISP) through JTAG, and 5.0 V core operation. The device provides predictable timing with fixed propagation delays, multi-voltage I/O support for 3.3 V and 5 V interfaces, and a programmable power-saving mode that reduces individual macrocell power when logic is idle, while an enhanced security bit protects user designs from unauthorized read-back. The MAX 7000 architecture implements each macrocell as a product-term array feeding a programmable register, with a shared programmable interconnect array (PIA) routing signals between LABs. The EEPROM process technology allows unlimited reconfiguration cycles via JTAG, supporting field upgrades and rapid prototyping. The 4-LAB organization enables wide logic integration for state machines, address decoding, and bus-interface glue logic. Typical applications include bus-interface bridging, address decoding and wait-state generation, glue logic replacement around microprocessors and DSPs, peripheral control in industrial systems, and rapid prototyping of glue logic on 5 V legacy boards. The wide-gate count and JTAG ISP make it suitable for production designs that need flexibility without an FPGA. When designing with this part, observe 5 V supply tolerance on inputs and use level shifters for 3.3 V logic interfaces; the JTAG chain can remain populated during in-circuit test for board-level diagnostics. Decouple the VCC pins with 0.1 uF ceramic capacitors placed close to the package, and consult the manufacturer datasheet for the full PGA pin assignment.

According to the manufacturer datasheet, the device is fabricated on a 0.30 µm CMOS EEPROM process and supports system frequencies up to 100 MHz. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks interconnected by a programmable switch matrix. Within the broader semiconductor taxonomy, a CPLD sits between simple SPLDs (e.g., PAL/GAL) and FPGAs, offering deterministic timing, instant-on configuration from on-chip EEPROM, and high fan-in logic — making it ideal for glue logic, bus decoding, and interface bridging. The MAX 7000S series specifically adds in-system programmability via JTAG, enabling field upgrades without removing the device from the board. Key differentiating features of the EPM7192SQC160-10N include its 12 Logic Array Blocks (LABs) of 16 macrocells each, a programmable speed/power optimization mode that lets speed-critical portions of a design run at full speed while other portions run at 50% lower power with only a nominal timing penalty, and four dedicated global clock inputs.

The device supports multiple I/O standards including 5.0 V CMOS and 3.3 V PCI-compatible signaling through its JTAG-configurable I/O structure. The MAX 7000S architecture provides predictable, deterministic timing because every logic path traverses the same predictable interconnect structure — unlike SRAM-based FPGAs that require device configuration on power-up. This makes the EPM7192SQC160-10N particularly well-suited to applications where instant-on behavior is critical and where designers need fixed propagation delays for worst-case timing analysis. The 10 ns tPD (pin-to-pin delay) of this -10N speed grade supports clock frequencies up to 100 MHz in combinatorial paths.

Designers frequently choose this part when they need non-volatile, deterministic logic with the convenience of JTAG in-system reprogrammability. When designing with this device, pay careful attention to I/O bank supply pin requirements — VCCINT and VCCIO may need separate rails depending on the mixed-voltage interface scheme, and unused pins should be configured as outputs driving ground to minimize power. The 160-pin PQFP footprint requires careful PCB routing given the 0.65 mm pitch; an external JTAG header is recommended for ISP access during prototyping and field firmware updates.

The MAX 7000S architecture uses an EEPROM-based configuration cell array, so the device retains its logic pattern with no external boot memory and can be reprogrammed in-circuit up to 100 cycles. The 5.0-V ISP interface uses the standard 4-wire JTAG TAP, simplifying board-level bring-up. Each macrocell supports combinatorial or registered operation with separate sum-of-products terms for both output enable and registered feedback, giving flexible control over tri-state buses and registered outputs. Typical applications include bus interface bridging, address decoding and glue logic for microprocessor systems, peripheral controller hubs, JTAG-controlled board-level configuration, and replacement of multiple discrete 74LS/74F/74HC TTL packages. It is also used in legacy industrial controllers and avionics subsystems where instant-on, non-volatile logic is mandatory. When designing with this part, pay attention to the 5 V VCC requirement and observe the JTAG ISP programming voltage levels. Decoupling should follow the manufacturer guidance with 0.1 µF caps close to each VCC/GND pair. For new designs, consider MAX II or MAX V devices unless EEPROM-based instant-on is required.

The MAX 7000S architecture uses a programmable interconnect array (PIA) to route signals between logic array blocks (LABs), each containing 16 macrocells with individual product-term allocation. This architecture delivers predictable, fixed timing independent of routing, a critical advantage over FPGA fabric for deterministic control paths. Typical applications include industrial control glue logic, bus interface and protocol bridging, power-up sequencing state machines, legacy system replacement, and instrumentation front-end control. The 5.0 V I/O interface allows direct connection to legacy TTL/CMOS peripherals without level shifters. When designing with this device, note that the MAX 7000S family is a mature, legacy architecture; verify availability and consider MAX II or MAX V migration for new designs.

EPM7192SQI160-10N - MAX 7000S CPLD, 192 Macrocells, 100MHz | Altera
The Intel (formerly Altera) EPM7192SQI160-10N is a high-density, high-performance CMOS CPLD from the MAX 7000S family, packaged in a 160-pin PQFP and featuring 192 macrocells, 124 user I/Os, and 3.75K usable gates with -10 speed grade (10 ns pin-to-pin delay). The 'N' suffix denotes the industrial operating temperature range of 0C to 70C, while the 'S' indicates in-system programmability via 5.0V EEPROM. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that sits between simple PAL/GAL devices and high-density FPGAs in the programmable logic hierarchy. CPLDs are characterized by instant-on (no boot/configuration load required), deterministic timing, and EEPROM or flash-based configuration that retains its bitstream through power cycles. They belong to the broader class of programmable logic devices (PLDs) and are widely used for glue logic, bus interfacing, and state-machine implementation where fast, predictable response is more important than raw logic density. Key features of this part include a 10 ns pin-to-pin propagation delay, internal counter frequencies up to 167 MHz, 5.0V in-system programmability (ISP) via JTAG, and support for hot-socketing. The device is fabricated in 5V CMOS technology and integrates 192 macrocells arranged in Logic Array Blocks (LABs) interconnected by a programmable interconnect array (PIA). It also supports the IEEE 1149.1 boundary-scan standard for board-level testability. From an architectural perspective, the MAX 7000S family uses Altera's second-generation MAX architecture with each macrocell containing a programmable AND/OR array, a flip-flop, and product-term allocation logic. The EEPROM configuration memory provides non-volatile storage without external boot devices, and the 5V-tolerant I/O structure allows direct interface with TTL and CMOS logic of mixed-voltage systems without level-level shifting in most cases. Typical applications include bus interfacing (PCI bridge glue logic, address decoding), state-machine controllers in industrial automation, glue logic between microprocessors and peripherals, motor-control sequencing in factory automation, and legacy 5V system designs where non-volatile, deterministic logic is required. Designers should note the PQFP-160 package's lead pitch of 0.5 mm and verify PCB footprint compatibility with the device footprint before re-spinning layouts. The 5V supply requirement is non-negotiable; this device is not compatible with 3.3V-only rails without a level translator. Programming is performed via JTAG using Altera/Intel Quartus or legacy MAX+PLUS II software.

MAX 7000A devices are built on a 0.30 µm EEPROM process and provide 5,000 usable gates, in-system programmability (ISP) through the IEEE 1149.1 Joint Test Action Group (JTAG) interface, and 3.3V core operation that is 5V-tolerant on I/O pins. CPLDs are typically chosen when deterministic timing, instant-on non-volatile configuration, and high drive strength are required - features that FPGAs cannot match without external configuration memory. Key features of the EPM7256AEFC100-10N include 256 macrocells distributed across 16 LABs (16 macrocells per LAB), 84 user I/O pins on a 100-ball FBGA footprint (11 x 11 mm), four dedicated inputs, an internal 3.3V operation with 5V-tolerant I/O, multiVolt I/O supporting 1.8V/2.5V/3.3V/5V mixed-voltage environments, JTAG-based IEEE 1149.1 boundary-scan and ISP, and built-in PCI compatibility. The -10 speed grade indicates a 10 ns maximum pin-to-pin delay (tPD), making this variant suitable for sub-100 MHz synchronous designs where -7 (7.5 ns) or -15 (15 ns) alternatives may be over- or under-specified. Architecturally, the device combines a programmable AND/OR/PLA-style logic fabric with a global interconnect, a per-macrocell flip-flop with selectable clear/preset/clock, and a programmable interconnect array (PIA) that routes signals between LABs with deterministic delay. The EEPROM-based configuration cell provides instant-on behavior in under 100 µs and supports 100 in-system program/erase cycles, enabling field upgrades without removing the device from the board. Typical applications include high-speed bus-interface bridging (PCI, ISA, VME, PCMCIA), address decoding and chip-select generation for microprocessors and DSPs, glue-logic consolidation in networking line cards and base stations, peripheral interfacing in telecom and industrial control equipment, and state-machine implementation where deterministic 10 ns timing is required. Designers should ensure that the JTAG pins (TCK, TMS, TDI, TDO) are accessible for ISP, that decoupling capacitors (0.1 µF and 10 µF) are placed within 5 mm of each power pin, and that unused I/O are explicitly configured as outputs or inputs in the Quartus/MAX+PLUS II design to avoid floating-pin failures.

The device exposes 84 user I/Os for high-density glue-logic, bus-interface, and state-machine integration. A CPLD (Complex Programmable Logic Device) is a non-volatile, instantly-on programmable logic device that sits between discrete 74-series glue logic and larger FPGAs. It is typically used to implement boot-time-immune decode logic, I/O expander bridges, bus-arbitration state machines, and address-latching interfaces, and it boots in milliseconds because configuration is stored in on-chip EEPROM rather than loaded from external flash. Key features include in-system programmability via IEEE 1149.1 JTAG, 5 V tolerant I/O, programmable power management with pin-per-pin enable/disable, and four global clock networks with product-term or I/O-pin control. Each macro cell contains a programmable AND/OR array with a register that can be configured as D, T, JK, or SR flip-flop, and the 256 macro cells are partitioned into 16 Logic Array Blocks for efficient partitioning of wide decode and arithmetic functions. The MAX 7000A architecture combines an EEPROM-based configuration memory (true non-volatility - no external boot PROM) with a MultiVolt core and MultiVolt I/O interface, allowing the core to operate at 3.3 V while the I/O banks interface directly to 2.5 V, 3.3 V, or 5 V devices. The 100-pin FBGA offers a compact footprint that suits high-density PCB designs where TQFP variants would be too large. Typical applications span industrial control boards, telecom base-station glue logic, PCI/ISA bus decode in legacy industrial backplanes, address decoding in 32-bit embedded systems, and prototype ASIC replacement. Designers choose the MAX 7000A family for instant-on behavior, deterministic timing, and a known-silicon IP portfolio that has shipped for decades. When designing with this part, observe the 3.3 V VCCINT supply (separate from VCCIO if MultiVolt is used), keep JTAG chain lengths short, and respect the 100-FBGA thermal pad layout recommended in the Intel MAX 7000A device handbook. Decoupling the eight VCCINT and four VCCIO balls with 0.1 uF X7R ceramics placed within 3 mm of each ball cluster is recommended for reliable in-system programming.

The MAX 7000A architecture implements each macrocell with a programmable AND/OR array, a flip-flop, and a programmable output enable, with shared expanders and parallel expanders allowing efficient wide fan-in logic. The 5ns pin-to-pin delay and 172.4MHz internal frequency make this device well-suited for high-speed address decoding, interrupt steering, and synchronous state machines operating above 50MHz. Typical applications include high-speed bus decoding and bridging, address/data-validity generation for legacy microprocessors, I/O expansion for FPGAs lacking unused pins, glue-logic consolidation in telecom backplanes, and industrial PLCs. This device is also widely used in prototyping interfaces between 5V peripherals and 3.3V processors. When designing with this CPLD, remember that the FBGA-256 package is non-repairable once soldered - allocate a JTAG header on every board for in-system reprogramming and bench recovery.

Per the manufacturer description on Arrow and Heisener, the part is a 5K-gate, 256-macrocell, 126.6 MHz MAX 7000A device in a 100-pin FBGA tray. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like logic blocks on a single chip with a programmable interconnect matrix. In the broader taxonomy, a CPLD sits between a small FPGA and a discrete gate array: it provides deterministic, propagation-delay-based timing (often called "PAL-like" timing) with instant-on, flash- or EPROM-backed configuration. Designers typically use a CPLD when the design is dominated by wide combinational logic, decoders, and registered I/O - exactly the use cases the MAX 7000A family was designed for.

MultiVolt I/O supports interfacing to 2.5 V, 3.3 V, and 5.0 V logic families without external level shifters, which is critical when bridging legacy 5 V peripherals to modern 3.3 V processors. Typical applications include PCI/ISA bus address decoding and chip-select generation, asynchronous state machines for industrial controllers, I/O expansion and level translation between 5 V and 3.3 V domains, and configuration/reset sequencing for microprocessors and DSPs. The 100-ball FBGA package provides high board-density routing for designs that need all 84 I/O on a small PCB footprint. When designing with this part, ensure the JTAG chain order matches the BSDL file order in the Altera documentation. Decoupling must use 0.1 uF and 0.01 uF ceramic capacitors placed within 5 mm of each supply ball. Quiescent current for the MAX 7000A family is in the tens of milliamps; thermal dissipation is usually not a concern at typical clock rates, but junction temperature must stay within the -40 C to +85 C industrial range.

The device is in-system programmable through the IEEE 1149.1 (JTAG) interface and supports the 4-pin JTAG protocol for boundary-scan test. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell arrays on a single chip with a programmable interconnect network. CPLDs sit between simple SPLDs/PLDs and higher-density FPGAs in the programmable logic hierarchy, providing deterministic, predictable timing (typically 1 to 10 ns propagation delays), instant-on behavior from on-chip EEPROM, and a Logic Element Block (LEB) architecture suited to glue-logic, decoder, bus-interface, and state-machine replacement. The MAX 7000A family in particular targets PCI bus interface, peripheral bridging, and bus-arbiter designs where 5V-tolerant I/O and 3.3V core operation are required. Key features of the EPM7256AEFI256-7 include 16 Logic Array Blocks (LABs), each containing 16 macro cells for a total of 256 macro cells; 164 programmable I/O pins shared with dedicated JTAG and global control functions; in-system programmability (ISP) via JTAG; multi-volt I/O supporting 2.5V/3.3V/5.0V mixed-voltage interfacing; and a commercial operating-temperature grade of -40C to +85C. The device is PCI SIG-compliant for 33 MHz PCI 2.2 bus use in the -7 speed grade, making it a natural fit for legacy PCI add-in cards and embedded peripheral controllers. The architecture is built on a CMOS EEPROM-based macrocell fabric with a unified interconnect matrix that delivers fixed, deterministic propagation delays independent of routing density, in contrast to SRAM-based FPGAs whose timing depends on placement and routing. Each macro cell contains a programmable AND/OR array, a flip-flop, and a programmable output enable. The 256-pin FBGA package provides high I/O density for glue-logic-heavy designs and is footprint-compatible with other EPM7256AEFI256-xx speed-grade and temperature-grade variants in the same family. Typical applications include PCI peripheral interface logic (33 MHz), glue logic for microprocessor and DSP systems, bus decoders and arbiters, peripheral bus-bridges between ISA/PCI and local microcontrollers, state-machine and sequencer replacement in industrial controllers, and JTAG-based boundary-scan chain extension for board-level test. Designers migrating from 5V-only legacy PLDs use the MAX 7000A's mixed-voltage I/O to bridge 5V peripherals to a 3.3V core without external translators. When designing with this part, plan for a clean 3.3V rail with adequate bulk decoupling on each FBGA power pin pair (VCCINT and VCCIO), because the FBGA package's multi-row ball array requires careful PCB fan-out. Use the Quartus II or MAX+PLUS II design software for fitting, simulation, and JTAG programming; legacy MAX+PLUS II projects must be migrated to Quartus II for newer tool support. Always verify that the I/O bank voltage matches the driven peripheral's VOH/VOL requirements, as the multi-volt I/O core uses separate VCCIO rails per bank.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PLA-like macrocell arrays into a single chip with a global interconnect fabric. In the broader taxonomy, a CPLD sits between small PAL/GAL devices and large SRAM-based FPGAs, offering deterministic 5-10 ns pin-to-pin delays, instant-on behavior from internal flash/EEPROM, and simplified I/O modeling - making it ideal for glue logic, address decoding, bus interface bridging, and power-up state machines where predictable timing matters more than gate density. Key features include 256 macrocells organized in 16 Logic Array Blocks (LABs), 6 dedicated inputs per LAB for fast register feedback, programmable power-saving modes that reduce I/O current up to 50%, and a MultiVolt core that supports 3.3 V operation with mixed 5.0 V/3.3 V/2.5 V I/O. Programmable interconnect supports both AND and OR array synthesis, enabling efficient implementation of wide combinatorial and registered logic. Each macrocell includes a programmable register that can be configured as D, T, JK, or SR flip-flop with independent clock, clock-enable, clear, and preset controls. The MAX 7000A architecture uses an enhanced EEPROM-based logic element that achieves 100% stuck-fault testability through the JTAG boundary-scan chain. With 6,400 usable gates (typical) and an I/O count supporting bus widths from 8 to 40 bits, the device is well suited to high-performance peripheral bridging applications. The -5 speed grade places it in the mid-band of the MAX 7000A family, balancing speed against power consumption. Typical applications include bus-interface bridging (PCI-to-ISA, microcontroller-to-DSP), peripheral glue logic in networking and telecom line cards, address decoding and arbitration in microprocessor systems, and high-speed state-machine control in industrial automation. The wide I/O count and fast 5 ns delay also suit LED display drivers and instrumentation front-ends. When designing with the EPM7256AETC100-5C, note that ISP via JTAG requires a 10 kΩ pull-up on the JTAG TCK pin and proper TDO/TMS/TDI routing. The MultiVolt interface enables direct connection between 5 V and 3.3 V devices without external level shifters, simplifying mixed-voltage PCB designs.

EPM7256AETC100-5N - 256-Macro MAX 7000A CPLD, 5ns TQFP-100
The Intel (formerly Altera) EPM7256AETC100-5N is a high-performance, EEPROM-based CPLD from the MAX 7000A family, delivering 256 macro cells, 84 user I/Os, and a 5.0 ns pin-to-pin delay in a 100-pin TQFP (1.0 mm pitch) commercial-grade package. It is fabricated on advanced CMOS technology, operates from a single 3.3 V supply, and is rated for 600 to 10,000 usable gates with counter speeds up to 227.3 MHz. The -5 speed grade places it among the fastest pin-to-pin timing options in the MAX 7000A series for glue-logic, bus decoding, and state-machine consolidation. What is a CPLD? A Complex Programmable Logic Device is a non-volatile, instantly-on programmable logic IC that combines the deterministic timing of PAL/GAL architecture with higher macro-cell density and on-chip user flash. CPLDs sit above simple PLDs and below FPGAs in the programmable-logic hierarchy (PLD -> CPLD -> FPGA), and are commonly used as interface bridges, bus controllers, address decoders, and power-up sequencers because they boot in microseconds from internal EEPROM. Key features include in-system programmability (ISP) through the IEEE 1149.1 JTAG port, multiVolt I/O supporting 2.5 V, 3.3 V, and 5.0 V mixed-voltage interfaces, an open-drain output option, programmable security bit for design protection, and a 100-pin TQFP that supports commercial (0C to 70C) ambient operation. The MAX 7000A architecture provides 16 macro cells per logic array block (LAB) with a programmable interconnect array (PIA) that guarantees fixed, predictable propagation delays regardless of routing density. Architecturally, the device uses a classic EEPROM-based logic-block fabric with per-macro-cell flip-flops, product-term expansion, and a global interconnect that delivers the trademark deterministic timing of the MAX 7000 family. The 3.3 V core combined with multiVolt I/O banks makes it ideal for bridging legacy 5 V peripherals to modern 3.3 V processors without external level shifters. Typical applications include PCI/ISA bus decoding, address/data demultiplexing, asynchronous-to-synchronous clock-domain bridging, glue logic for microcontroller/microprocessor systems, and power-sequencer circuits for multi-rail boards. Designers choose this part when deterministic timing, instant-on non-volatile configuration, and a mature Quartus II design flow are required. When designing with the EPM7256AETC100-5N, allocate at least one global clock pin per high-speed logic block, place 0.1 uF decoupling capacitors within 5 mm of every supply pin, and use the JTAG chain carefully when ISP is enabled. The 100-pin TQFP has a 0.5 mm lead pitch that supports hand-soldering with practice but is best assembled by reflow.

EPM7256AETC100-7 - 256-Macrocell MAX 7000A CPLD, 7.5ns TQFP-100 | Intel
The Intel EPM7256AETC100-7 is a 3.3-V, EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 7000A family, providing 256 macrocells, 5,000 usable gates, and 84 user I/Os in a 100-pin TQFP package with a 7.5 ns pin-to-pin logic delay. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell arrays on a single chip with predictable, deterministic timing. CPLDs sit in the broader taxonomy of programmable logic devices (PLD -> CPLD/FPGA -> logic IC -> integrated circuit), filling the niche between simple gate arrays and high-density FPGAs. They are favored for glue logic, bus interfacing, state-machine control, and power-up instant-on applications where deterministic timing and in-system programmability are required. The EPM7256AETC100-7 features 256 macrocells organized in logic array blocks (LABs), with each macrocell containing a programmable AND/OR array and a configurable flip-flop. The device supports in-system programmability (ISP) via JTAG (IEEE 1149.1), eliminating the need for a separate programmer. Its 3.3 V core supply with 5 V tolerant I/O on selected pins enables easy interfacing with mixed-voltage systems, while the 7.5 ns tPD supports high-speed control applications at frequencies up to 126.6 MHz. Typical applications include bus interface bridging (PCI, ISA, VME), peripheral glue logic, address decoding and chip-select generation, state-machine controllers, and power-up sequencing logic in microcontroller and ASIC systems. The MAX 7000A architecture also includes programmable interconnect switches, user-defined macrocell flip-flop clocks, and a global clear pin for synchronous design initialization. When designing with this part, note that the device has been classified as obsolete/end-of-life by Intel - consider the EPM7256AETC100-7N or EPM7256AETI100-7N variants for new designs. Verify the tPD speed grade (7 = 7.5 ns) and temperature grade (C = commercial 0 to 70C) match your application requirements before substituting.
