The Altera (now Intel) EPM7064SLC44-10N is a high-density, high-performance CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 7000 family, featuring 64 macro cells, 36 user I/Os, a 10 ns pin-to-pin propagation delay, and a 44-pin PLCC package. Built on Altera's second-generation Multiple Array MatriX (MAX) architecture, the device delivers 1,250 usable gates and supports in-system programmability (ISP) via the IEEE-Standard 1149.1 (JTAG) interface. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that combines multiple PAL-like macro-cell logic blocks on a single die, connected through a programmable interconnect matrix. CPLDs sit in the hierarchy between simple PLDs (PALs/GALs) and FPGAs, offering deterministic, near-zero-power standby, instant-on configuration, and predictable timing — making them ideal for glue logic, bus interfacing, and control applications where FPGAs would be over-spec and PALs would lack capacity. Key features include 5V CMOS core operation, four dedicated input pins that also serve as global clock/clear/Output Enable resources, programmable macro-cell flip-flops with individual clear, preset, clock, and enable control, and an extended IEEE-Standard 1149.1 boundary-scan test interface. Each user I/O can be configured per-pin for 3.3V or 5V PCI-compliant drive strength. The non-volatile EEPROM configuration cell means the device powers up instantly with no external boot PROM required. Architecturally, the EPM7064SLC44-10N partitions its 64 macro cells into four Logic Array Blocks (LABs), each containing 16 macro cells, with a programmable interconnect array (PIA) that routes any signal to any destination. The 10 ns tPD (with the -10 speed grade suffix) supports counter frequencies up to 125 MHz, while higher-density MAX 7000A/S/AE variants in the same family scale to 256 macro cells and 5 ns timing. Typical applications include bus decoding and address mapping in legacy 8051/68k designs, glue-logic integration for DSP/microprocessor systems, peripheral control (UART, SCSI, ISA bridge), state-machine implementation, and PCI bus interface glue. The wide 5V tolerance and 36 I/Os also suit industrial motor-control and instrumentation front ends. When designing with this device, observe the 5V ±5% supply requirement, place a 0.1 µF decoupling capacitor close to each VCC/GND pair on the PLCC-44 footprint, and configure unused I/Os as outputs driving low to minimize power consumption. The JTAG chain should be bypassed with TCK held low during normal operation if boundary-scan is unused.

The Altera EPM7096LC68-15 is a member of the classic MAX 7000 family of high-performance, EEPROM-based Complex Programmable Logic Devices (CPLDs), delivering 96 macrocells in a 68-pin PLCC package with a 15 ns pin-to-pin logic delay. Built on a second-generation MAX architecture, this device provides 5.0V in-system programmability (ISP) through its built-in IEEE Std. 1149.1 JTAG interface, enabling rapid prototyping and field upgrades without removing the part from the board. What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic IC that sits between simple SPLDs and large FPGAs in the programmable logic hierarchy. It contains multiple logic array blocks (LABs) interconnected by a programmable switch matrix, retaining its configuration in on-chip EEPROM without needing a separate boot memory. CPLDs are widely used for glue logic, bus interfacing, address decoding, state machines, and power-up control because of their deterministic timing, instant-on behavior, and robust non-volatile storage. Key features of the EPM7096LC68-15 include 96 macrocells, 4 logic array blocks (LABs), and 52 user I/O pins for flexible signal routing. The device operates from a 4.75 V to 5.25 V supply, supports the standard 5V TTL interface levels, and offers a 15 ns maximum propagation delay that suits moderate-speed control logic. Its high-performance EEPROM technology delivers 100 erase/program cycles per macrocell and supports in-system programming through JTAG or via Altera's ByteBlaster/ByteBlasterMV download cables. The MAX 7000 architecture separates combinational and registered logic, with each macrocell containing a programmable AND/OR array and a configurable flip-flop. This design gives predictable timing paths and makes the EPM7096LC68-15 particularly attractive for asynchronous and registered state-machine designs. The device is also highly tolerant of 5V mixed-signal environments, which is why it remains common in legacy industrial, telecommunications, and test equipment designs. Typical applications include bus interfacing and protocol bridging, address decoding for microprocessors, state-machine controllers, glue logic replacement for discrete 74-series TTL, and I/O expansion. Designers also use the EPM7096LC68-15 for power-up sequencing logic because its non-volatile EEPROM boots in a deterministic state without an external configuration device. When designing with this CPLD, account for the 5V supply requirement and provide proper decoupling on every VCC pin. The PLCC-68 package is socket-compatible with several EPM7128 variants, allowing a path to higher macrocell density without reworking the PCB footprint. This page synthesizes distributor inventory, drop-in alternatives, and practical design notes not found in the bare manufacturer datasheet, making it a faster reference for engineers evaluating, sourcing, or replacing the EPM7096LC68-15.
EPM7096LC68-7 - 96-Macrocell MAX 7000 CPLD, 7.5ns | Intel
The Intel EPM7096LC68-7 is a high-density, EEPROM-based Complex Programmable Logic Device (CPLD) from the legacy MAX 7000 family, packaged in a 68-pin J-Lead PLCC (LC68). The part integrates 96 macrocells organized into 4 Logic Array Blocks (LABs) with 52 user I/O pins, and offers a worst-case pin-to-pin propagation delay of 7.5 ns. Operating from a 5.0 V supply, this device targets glue-logic, bus-interface bridging, and state-machine consolidation in industrial, telecom, and embedded control designs. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits in the broader programmable logic hierarchy between simple SPLDs (like GAL/PAL) and high-capacity FPGAs. CPLDs use EEPROM or flash cells to retain configuration, provide deterministic timing with predictable pin-to-pin delays, and typically contain hundreds of macrocells grouped into LABs interconnected by a programmable interconnect matrix (PIA). They are commonly chosen for applications needing instant-on behavior, robust I/O driving capability, and small-form-factor logic integration at low power. Within the programmable logic taxonomy, the MAX 7000 family sits as one of the longest-lived mainstream 5 V EEPROM CPLD lines introduced by Altera (now Intel). Key features of the EPM7096LC68-7 include 5.0 V in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface, a maximum toggle frequency that supports common bus-interface speeds, six dedicated global clock pins, and a programmable power-saving mode that reduces quiescent current on unused macrocells. Each macrocell contains a programmable AND/OR array with a flip-flop, providing both combinational and registered logic in a single architectural unit. The LC68 (PLCC-68 J-lead) package is socket-compatible across the MAX 7000 series, enabling board reuse between density variants. Architecturally, the MAX 7000 uses a second-generation MAX architecture with enhanced interconnect routing and per-macrocell product-term allocation. The four LABs share a Programmable Interconnect Array (PIA) that routes any LAB output to any other LAB input, removing routing bottlenecks common to older PLD families. Combined with the 52 I/O pins, the device delivers sufficient logic density for 16-/32-bit bus decoding, address-latch multiplexing, and peripheral control blocks in legacy 5 V systems. Typical applications include 5 V ISA bus decoding, industrial PLC I/O expansion, peripheral glue logic in telecom line cards, address/data multiplexing for microprocessors without integrated peripherals, and pin-compatible board upgrades from smaller MAX 7000 devices (EPM7032, EPM7064, EPM7128). The part is widely used for new designs targeting legacy 5 V rails and for long-lifecycle industrial equipment maintenance where firmware-updateable logic simplifies field upgrades. When designing with this part, allow at least one 0.1 uF decoupling capacitor per VCC/GND pair, place the JTAG TMS/TCK/TDO/TDI chain with proper pull-ups, and verify the device programming file (POF/JEDEC) targets the correct speed grade (-7 = 7.5 ns tPD). Note that EPM7096LC68-7 is generally considered a legacy/NRND device; engineers should confirm long-term availability before new design-in.
EPM7096LC84-10 - 96-Macrocell MAX 7000 CPLD, 10ns, 84-PLCC | Intel
The Intel (formerly Altera) EPM7096LC84-10 is a 96-macrocell, 84-pin PLCC member of the MAX 7000 family of high-performance, EEPROM-based Complex Programmable Logic Devices (CPLDs). Built on the second-generation MAX architecture, this device provides 4 Logic Array Blocks (LABs), 96 macrocells, and 36 usable I/O pins, with a pin-to-pin propagation delay (tPD) of 10 ns for the -10 speed grade. The 'L' suffix indicates a low-power CMOS process variant, and 'C' indicates the commercial 0C to +70C operating range. A Complex Programmable Logic Device (CPLD) is a non-volatile, reprogrammable digital integrated circuit that sits hierarchically between simple SPLDs/GALs and full FPGAs. Within the broader taxonomy, CPLDs fall under programmable logic devices (PLDs), which sit under digital logic ICs, which in turn belong to the integrated circuit (semiconductor) family. CPLDs are valued for their deterministic timing, instant-on EEPROM configuration, and predictable I/O behavior, making them well suited to glue-logic, bus-interface, and control-plane tasks in mixed-signal systems. The EPM7096LC84-10 features 5.0-V in-system programmability (ISP) through the built-in IEEE Std. 1149.1 Joint Test Action Group (JTAG) interface. It supports MultiVolt I/O for interfacing with 2.5-V, 3.3-V, and 5.0-V logic on the same die, and provides programmable macrocell flip-flops with selectable D, T, JK, or SR operation. The shared programmable interconnect array (PIA) routes signals between LABs, and each macrocell includes a product-term-based logic array, a programmable register, and a tri-state output buffer for bidirectional I/O. Typical applications of the EPM7096LC84-10 include address decoding and bus-interface glue logic in 5-V microcontrollers and DSP systems, peripheral control for printers and legacy industrial controllers, state-machine-driven I/O expansion, JTAG-boundary-scan test access, and replacement of multiple discrete 74LS/74HC TTL gates to reduce board area. Because the MAX 7000 uses EEPROM cells, designs retain their configuration through power cycles with no external boot PROM. When designing with this device, ensure that VCC stays within the 4.75 V to 5.25 V commercial range, that JTAG signals TDI/TMS/TCK/TDO are pulled to a defined logic level when not in use, and that I/O rise/fall times are accounted for in timing closure - the shared PIA structure means worst-case tPD is identical for any internal path. For new designs, evaluate MAX II or MAX V modern low-power equivalents, which consume less quiescent current and offer smaller packages while maintaining 5-V tolerant I/O. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone - use it alongside the official MAX 7000 datasheet from Intel.
EPM7096LC84-15 - 96 Macrocell, 15ns CPLD MAX 7000 | Intel / Altera

The device integrates four Logic Array Blocks (LABs) connected via a programmable interconnect array (PIA), giving designers 68 usable I/O pins with 5V-tolerant inputs. What is a CPLD? A Complex Programmable Logic Device (CPLD) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell blocks on a single chip, connected by a central interconnect matrix. In the broader taxonomy, CPLDs sit between simple SPLDs (like PALs/GALs) and high-density FPGAs, offering deterministic timing, instant-on non-volatile configuration, and modest logic densities (hundreds to a few thousand macrocells). CPLDs are widely used as glue logic, interface bridges, and high-speed control state machines where FPGAs would be over-spec or cost-prohibitive. The EPM7096LC84-15's key differentiating specifications include 76.9 MHz maximum operating frequency, 10 ns logic-array-block propagation delay, 36 user-available I/O pins per LAB, and built-in JTAG boundary-scan support compliant with IEEE 1149.1. The second-generation MAX architecture combines EEPROM cells with CMOS logic, providing 100% tested programming yield, 100 erase/program cycles endurance, and data retention exceeding 10 years. Architecturally, the device uses a CMOS EEPROM process with a 5V core supply, dual-sense-amplifier configurable macrocells, and a global interconnect array with predictable routing delay independent of logic placement. This deterministic timing behavior is a hallmark of CPLDs and is often cited as the reason designers choose MAX 7000 over a small FPGA for control-path glue logic. Typical applications include bus-interface bridging (e.g., 8-bit/16-bit microcontroller to 32-bit bus), high-speed address decoding, state-machine based motor and actuator control, peripheral expansion for legacy designs, and JTAG-controlled glue logic in telecom and industrial backplanes. When designing with this part, note that the 5V VCC must rise monotonically during power-up to ensure proper configuration. Designers should also budget 100 erase/program cycle endurance and avoid continuous in-system reprogramming in field-deployed systems.

The device operates from a single 5.0 V supply (VCCINT/VCCIO combined for the LC family) and supports commercial temperature ranges. Pin-compatibility across the MAX 7000 family allows migration between EPM7064, EPM7096, and higher densities within the same 84-pin PLCC footprint. The MAX 7000 architecture is built on EEPROM non-volatile cells with a second-generation MAX architecture, providing five-pin programmable logic delays, programmable flip-flops with individual clear, preset, clock, and clock-enable controls, and a programmable interconnect array (PIA) that routes signals between LABs. This gives deterministic, simulation-matched timing for asynchronous state machines and address decoding. Typical applications include bus address decoding, peripheral glue logic, interface bridging between microcontrollers and legacy peripherals, asynchronous state machines, and board-level reset/power-sequencing controllers in industrial, telecom, and embedded computing systems. The wide 5V tolerance and instant-on behavior are particularly valued in 5V legacy industrial backplanes. When designing with this part, ensure the JTAG chain (TCK, TMS, TDI, TDO) is correctly terminated and that the I/O banks are powered simultaneously to avoid latch-up. The 7.5 ns speed grade is the slowest in the MAX 7000 family at this density - if your design requires faster decode paths, consider the EPM7096LC84-10 or EPM7096LC84-15 speed grades (drop-in, faster).

From a technical depth perspective, the MAX 7000 architecture uses a global interconnect that routes every LAB signal to every other LAB through a single fast connective path. Each LAB contains 16 macrocells and an I/O block. The 'L' suffix indicates the low-power variant and the 'I' suffix denotes industrial temperature grade. The -15 speed grade sets tPD (pin-to-pin) at 15ns, suitable for 33 MHz-66 MHz state-machine and decoder-style glue logic. Typical applications include bus interface bridging, address decoding, state-machine control, peripheral glue logic in microcontroller/ASIC systems, and legacy industrial control replacement. The JTAG ISP capability makes board-level upgrades and field reprogramming practical without removing the device from the circuit. When designing with the EPM7096LI68-15, observe PLCC-68 PCB layout guidelines including proper land pattern per JEDEC MS-018, decoupling capacitor placement near VCC pins, and JTAG chain integration if multiple devices share the same boundary-scan test port.

Multiple speed grades (-5, -7, -10) allow designers to balance timing margin against cost across the same pin-compatible footprint. Typical applications include PCI bus interface glue logic, address decoding for microprocessor systems, high-speed state machines, and bus arbitration in telecommunications equipment. The wide operating voltage range also supports industrial 5V-tolerant I/O via dedicated 5V-tolerant pins. Compared to FPGA alternatives, the EPM7128AEFC100-5 offers instant-on behavior with no external configuration memory required, simplifying board design and reducing BOM cost. When designing with this device, ensure adequate power supply decoupling (typically 0.1uF and 10uF capacitors near each VCC pin) and follow Altera's JTAG programming guidelines for ISP. Designers should also consider the timing model carefully - propagation delay specifications assume specific output loading and operating conditions that must be replicated in the target system.

The non-volatile EEPROM cells retain the programmed logic across power cycles, providing instant-on behavior at sub-microsecond times, which is critical in industrial control and PCI bus glue applications where the host processor expects deterministic configuration before reset deassertion. Typical applications include PCI bus interface glue logic, glue logic for microprocessor and DSP systems, bus decoding and address mapping, state-machine controllers, and 5V-to-3.3V translation bridges. Industrial and telecom equipment designs frequently pair the EPM7128AE with host processors to implement custom peripherals, bus arbitration, and timing-sensitive I/O expansion. When designing with this device, note that the 'N' suffix denotes lead-free / Pb-free assembly. Designers migrating from older 5V MAX 7000S parts must verify input-threshold compatibility because the AE core operates at 3.3V while outputs are 5V tolerant only with external pull-up. Always consult the MAX 7000AE Programmable Logic Device Family Data Sheet for timing model details.

Designers choose the EPM7128A when they need fast deterministic timing, instant-on non-volatile configuration, and 5V-tolerant I/O in a moderate-density package. A key design consideration is power sequencing: the Altera datasheet requires VCC to rise monotonically for the EPM7128A family to avoid spurious configuration events. Designers should also observe the 5.0V input tolerance window (VCCIO = 3.3V) and choose 3.3V or 2.5V output drive levels based on the downstream logic family.

It operates from a 3.3 V core supply and is built on a CMOS EEPROM process that provides non-volatile, instant-on configuration with no external boot memory required. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines the instant-on behavior of PAL/GAL architectures with the density and macro-cell richness of small FPGAs. CPLDs sit in the programmable-logic hierarchy above simple PLDs and below FPGAs, and are commonly used for glue logic, bus decoding, address decoding, state-machine control, and power-sequencing tasks in digital systems. The MAX 7000A family uses a classic EE (Electrically Erasable) configuration memory, allowing the device to retain its programmed logic across power cycles without an external configuration PROM. Key features of the EPM7128AETC144-10N include up to 100 user I/O pins across 4 I/O banks, 128 macro cells, 250 MHz internal performance, JTAG-compliant IEEE 1149.1 boundary-scan support, multiVolt I/O supporting 2.5 V/3.3 V/5 V mixed-voltage interfacing, and a propagation delay of 4.5 ns through the logic array.

EPM7128AETC144-7 - 128-Macrocell 7.5ns MAX 7000A CPLD | Intel
The Intel (formerly Altera) EPM7128AETC144-7 is a 128-macrocell, 2,500-gate CMOS Complex Programmable Logic Device (CPLD) from the MAX 7000A family, housed in a 144-pin TQFP (20x20 mm) package with 100 user I/Os. The "-7" speed grade denotes a maximum pin-to-pin logic delay (tPD) of 7.5 ns and a maximum operating frequency of roughly 129.9 MHz, suitable for glue-logic, bus-interface bridging, and state-machine control in cost-sensitive industrial and commercial designs. The "AET" device code indicates the 3.3 V core variant with in-system programmability via the IEEE 1149.1 JTAG interface and the legacy Altera ByteBlaster/USB-Blaster pin header. A CPLD (Complex Programmable Logic Device) is a non-volatile, EEPROM- or flash-backed programmable logic device that sits hierarchically below FPGAs in the programmable logic family tree: programmable logic device (PLD) -> CPLD -> MAX 7000A series -> 3.3 V EEPROM CPLD. Unlike SRAM-based FPGAs that require a configuration flash, a MAX 7000A CPLD is instantly ready at power-up with deterministic pin-to-pin timing, which is the principal reason it is still chosen for boot-time-critical glue logic, address decoding, and interrupt steering in microcontroller and processor-based systems. Key features include 128 macrocells distributed across 8 logic array blocks (LABs), 100 usable I/Os, a 3.0 V to 3.6 V single-supply range, JTAG-based IEEE 1149.1 boundary-scan test and ISP, open-drain or active-high configuration options, and a commercial operating temperature range of 0C to +70C. The device also supports the MAX 7000A family's MultiVolt I/O, allowing mixed-voltage interfacing to 5.0 V, 3.3 V, and 2.5 V logic rails on the same die. The EEPROM configuration cell guarantees zero-power standby retention and 100 (typical) / 10 (minimum) in-system programming endurance cycles per macrocell. Architecturally, the EPM7128AETC144-7 combines a programmable interconnect array (PIA) with eight LABs, each containing 16 macrocells. Each macrocell integrates a programmable AND/OR/registered-logic array with a product-term allocator, a programmable register (D/T/JK/SR), and an I/O control block. The PIA routes any LAB output or input pin to any other LAB, allowing the device to absorb wide combinatorial and registered logic without the routing congestion typical of small FPGAs. Because timing is fully deterministic and specified per macrocell, software tools such as Altera/Intel Quartus II and MAX+PLUS II can synthesize fixed-latency logic at compile time. Typical applications include 8/16/32-bit microcontroller and microprocessor glue logic, address decoding and chip-select generation, bus interfacing (e.g., 8-bit to 16-bit bus translation), state-machine controllers, power-sequencer logic, JTAG-controlled I/O expansion, and legacy industrial control boards that demand non-volatile, deterministic boot. Designers also use this part to replace multiple 74-series TTL/CMOS glue-logic ICs, saving board area, reducing BOM risk, and improving test coverage through built-in JTAG boundary scan. When designing with this part, ensure the JTAG chain (TCK/TMS/TDO/TDI) is correctly routed with series termination and that the ByteBlaster header respects the 3.3 V VCCIO used by the device. Quartus II / MAX+PLUS II software is required for synthesis; modern Quartus Prime versions have dropped MAX 7000A support in some releases, so legacy tool compatibility should be confirmed before committing to a long-lifecycle design.

Its non-volatile EEPROM cells ensure the design is retained without external configuration memory, while the JTAG interface enables in-system reprogramming during prototyping or field updates. Typical applications include PCI bus interface glue-logic, address decoding for microprocessors and microcontrollers, power-supply sequencing and supervisory logic, industrial control and factory-automation glue logic, and legacy 5 V-to-3.3 V system migration. Designers often select this part to consolidate discrete 74-series logic into a single programmable device while preserving boot-time determinism. When designing with this device, observe the recommended decoupling scheme (0.1 µF + 10 µF per supply) and ensure the JTAG chain is terminated correctly. The 7.5 ns speed grade is suitable for designs clocked up to ~129.9 MHz; for higher-frequency logic, choose the -5 or -6 speed grade variants.

A CPLD (Complex Programmable Logic Device) is a non-volatile digital integrated circuit that combines the instant-on, deterministic timing of PAL/GAL architecture with higher logic density and I/O count. Within the broader taxonomy, CPLDs sit between simple SPLDs (PAL/GAL) and FPGAs: they offer faster, predictable timing than FPGAs at the cost of lower logic density, and they boot instantly without external configuration memory. The MAX 7000A family targets glue-logic, bus-interface, state-machine, and power-sequencing applications where deterministic propagation delay matters more than raw LUT count. Key differentiating features of the EPM7128AETI100-7 include the MultiVolt I/O interface, which allows the device core to operate at 3.3 V while I/O banks interface with 2.5 V, 3.3 V, or 5 V systems; four dedicated inputs for global clock/clear/preset; and a Joint Test Action Group (JTAG) IEEE 1149.1 boundary-scan test interface for board-level testability. The -7 speed grade delivers 7.5 ns tPD, while the -10 grade trades speed for lower cost, and the -7N suffix denotes lead-free / RoHS compliance. The industrial temperature range (-40 C to +85 C) makes this part suitable for industrial controls, telecommunications infrastructure, and white-goods electronics. The internal architecture uses a programmable interconnect array that routes signals between the Logic Array Blocks (LABs), each of which contains 16 macrocells with configurable product-term logic, flip-flops, and sharing expanders. This structure yields deterministic, deterministic propagation delay independent of routing complexity, a hallmark of CPLD timing closure. Typical applications include bus-interface bridging (e.g., 8-bit/16-bit microprocessor-to-peripheral glue logic), address decoding, state-machine controllers, LED display multiplexing, and power-supply sequencing in industrial, automotive aftermarket, and telecom systems. Designers choose the EPM7128AETI100-7 specifically when they need a 5 V-tolerant 3.3 V core device in a 100-pin TQFP footprint that fits legacy board layouts migrated from earlier MAX 7000S (5 V) devices. When designing with this device, ensure that I/O banks are powered from rails matching the MultiVolt specification of the external logic, and place 0.1 uF and 1 uF decoupling capacitors within 5 mm of each VCCIO/VCCINT pin pair. For JTAG programming, dedicate four general-purpose I/Os as TMS, TCK, TDI, and TDO if boundary-scan test access is required in production.

EPM7128AETI100-7N - MAX 7000A CPLD 128 Macro 84 I/O | Intel/Altera
The Intel/Altera EPM7128AETI100-7N is a MAX 7000A-family Complex Programmable Logic Device (CPLD) with 128 macrocells, 2,500 usable gates, and 84 user I/Os in a 100-pin TQFP package, operating at 3.3 V with a 129.9 MHz internal frequency. Built on a 5 nm-equivalent EEPROM process, it delivers non-volatile, in-system programmable logic with 7 ns pin-to-pin propagation delay. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device consisting of multiple PAL-like macrocell arrays interconnected by a programmable switch matrix. CPLDs sit in the programmable logic hierarchy below FPGAs and above discrete glue logic, providing deterministic timing, instant-on behavior, and high-drive I/O for bus interface, address decoding, and state-machine tasks. The MAX 7000A family specifically targets 3.3 V systems with pin-compatible 5.0 V migration paths from the legacy MAX 7000S line. Key features include 128 macrocells, 84 user I/Os, 7 ns maximum propagation delay (tPD), 129.9 MHz maximum operating frequency (fCNT), and JTAG-compliant IEEE Std 1149.1 in-system programmability. The device supports multi-volt I/O for interfacing to 5.0 V, 3.3 V, and 2.5 V logic, and operates across an industrial temperature range of -40C to +85C. The 100-pin TQFP (14x14 mm) footprint is industry standard for this density tier. Architecturally, the MAX 7000A CPLD uses Logic Array Blocks (LABs) of 16 macrocells each, an interconnect matrix with both row and column global signals, and per-pin output enable control. Each macrocell contains a programmable AND/OR array feeding a programmable register with configurable clear, preset, and clock modes. The result is deterministic, glitch-free I/O with predictable timing independent of logic utilization - a hallmark distinction from SRAM-based FPGAs. Typical applications include bus-interface glue logic (PCI/ISA bridging), address decoding for embedded microprocessors, state-machine controllers in industrial automation, I/O expansion and level translation in telecom infrastructure, and pin-compatible legacy upgrade paths from MAX 7000S designs. The industrial temperature grade suits factory-floor and outdoor telecom environments. Designers should leverage the JTAG (IEEE 1149.1) interface for in-system programming and boundary-scan test, while paying attention to the multi-volt I/O bank's VCCIO pin assignment when mixing 3.3 V and 5.0 V signals on the same device.

EPM7128AETI144-10N - MAX 7000A CPLD, 128 Macrocells, TQFP-144 | Altera
The Altera (Intel Programmable Solutions Group) EPM7128AETI144-10N is a high-density EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 7000A family, delivering 128 macrocells, 2,500 usable gates, and a 10 ns pin-to-pin propagation delay in a 144-pin Thin Quad Flat Pack (TQFP-144) industrial-grade package. It features 100 user I/O pins, in-system programmability through the IEEE Std 1149.1 JTAG boundary-scan test interface, and operates from a single 3.0 V to 3.6 V supply with a nominal 3.3 V rail. A Complex Programmable Logic Device (CPLD) is a non-volatile, instant-on programmable logic device that sits in the hierarchy between simple PLDs and FPGAs. It typically consists of multiple PAL-like macrocell logic array blocks (LABs) interconnected by a global programmable interconnect matrix (PIA), with on-chip EEPROM or flash configuration memory. CPLDs are chosen when designers need deterministic timing, fast input-to-output propagation, and the ability to retain configuration without an external boot memory. The EPM7128AETI144-10N is built on a 0.35 µm CMOS EEPROM process and integrates four Logic Array Blocks (LABs) with 36 macrocells each, totaling 144 macrocells in the die. Each macrocell contains a programmable AND/OR array, a flip-flop, and dedicated product-term steering, which gives the device true single-chip, single-cycle operation with no external configuration PROM. The 10 ns tPD enables 125 MHz+ state-machine and interface-bridging clock rates, while the high-drive I/O cells support 5 V tolerant inputs on a 3.3 V VCCIO when configured for mixed-voltage systems. Typical applications include bus interface bridging (PCI, ISA, VME), peripheral glue logic in microcontroller/DSP systems, address decoding, state-machine controllers, and high-speed data-path multiplexing. The wide I/O count and JTAG ISP make it well suited for production-line programmable designs that need field upgrades without a programmer socket. When designing with this device, place the four global clock/clear pins on low-skew dedicated traces and follow Altera's TQFP-144 land-pattern recommendations. The EPM7128AETI144-10N is one member of the MAX 7000A family; selecting -7, -10, -12, or -15 speed grades trades off tPD against Icc.
