EPM7160ELI84-20 Visão geral
What is a CPLD? A 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 typically used for glue logic, bus interfacing, state-machine control, and power-up sequencing in digital systems where deterministic timing, fast input-to-output propagation, and instant-on behavior are required. The MAX 7000 family is one of the longest-lived CPLD families in the industry, having shipped continuously since the 1990s in industrial, telecommunications, and embedded designs.
Key features of the EPM7160ELI84-20 include 64 user I/O pins organized into four Logic Array Blocks (LABs), a pin-to-pin propagation delay of 20 ns (the '-20' speed grade), 5.0V core VCC operation, and programmable power-saving mode on a per-macrocell basis. The device also offers open-drain output options, programmable security bits for design protection, and JTAG boundary-scan test support per IEEE 1149.1.
Architecturally, the EPM7160ELI84-20 uses a classic MAX-style AND-OR plane with a programmable interconnect array (PIA) that provides deterministic, consistent routing delays across all logic paths, simplifying static timing closure compared to FPGAs. Each macrocell contains a programmable flip-flop, product-term selection logic, and a configurable I/O register, enabling efficient implementation of wide combinatorial and registered logic.
Typical applications include industrial control and factory-automation boards, telecommunications line cards and legacy backplane glue logic, PCI bus interface bridges, address decoding and interrupt controllers in embedded CPU designs, and replacement of multiple discrete 74LS/74HC logic devices on legacy PCBs. The instant-on, non-volatile nature of the MAX 7000 family makes it especially attractive for safety-critical boot logic and deterministic control.
When designing with this device, plan I/O assignments early - the 84-pin PLCC exposes 64 usable I/Os and four dedicated JTAG/programming pins, so not all 84 pins are user I/O. Use the Altera/Intel Quartus (or legacy MAX+PLUS II) toolchain for synthesis, fitting, and programming, and respect the 5.0V VCC requirement when mixing with 3.3V logic (the I/Os are 5V-tolerant inputs but cannot drive 3.3V outputs above their VCCIO).

Aplicações típicas
EPM7160ELI84-20 é adequado para 6 aplicaçãos: Industrial Control & Factory Automation, Telecommunications Backplane Glue Logic, Legacy PCI / ISA Bus Interface Bridges, Embedded CPU Address Decoding & Chip-Select Generation, Replacing Multiple 74-Series Discrete Logic ICs, Power-Up Sequencing & Reset Distribution.
Industrial Control & Factory Automation
The EPM7160ELI84-20 is well-suited for industrial PLCs, motor-control boards, and factory-automation controllers requiring deterministic glue logic between microcontrollers, sensors, and actuators. Its 160 macrocells and 64 user I/Os provide ample capacity to consolidate multiple 74LS/74HC discrete-logic packages into a single reprogrammable device, simplifying BOM and PCB layout. The industrial -40C to +85C temperature rating enables deployment in uncontrolled factory-floor environments without derating. The 20 ns pin-to-pin delay delivers deterministic timing for safety-interlock logic and emergency-stop signal paths. The 5V tolerance and JTAG ISP allow in-field firmware updates via standard programming hardware without removing the board from service, reducing maintenance windows in 24/7 production lines.
Recomendado
Telecommunications Backplane Glue Logic
Legacy telecommunications line cards, T1/E1 interface boards, and central-office switching equipment commonly use the EPM7160ELI84-20 for address decoding, interrupt steering, and bus-interface bridging. The 62.5 MHz maximum frequency and 20 ns tPD comfortably handle bus-cycle timing for 33 MHz PCI and proprietary backplane protocols at 5V logic levels. The 64 user I/Os can replace dozens of discrete 74FCT and 74ABT logic devices, freeing board area for higher-value signal-conditioning circuitry. EEPROM-based instant-on configuration eliminates the need for external boot PROMs, critical for telecom systems that must come up in a defined state after power restoration. JTAG boundary-scan testability per IEEE 1149.1 simplifies board-level test and field diagnostics.
Recomendado
Legacy PCI / ISA Bus Interface Bridges
The EPM7160ELI84-20 is widely deployed as a PCI-to-local-bus bridge, ISA bus decoder, and interrupt controller in embedded x86 systems where its 5V-tolerant I/Os and 20 ns propagation delay match the legacy bus timing budgets. Designers use its 160 macrocells to implement bus-state machines, address-decoder PLAs, and wait-state generators that would otherwise require multiple PAL/GAL devices. The 5.0V core supply aligns with PCI 5V signaling and ISA bus levels, avoiding the need for level shifters. EEPROM non-volatility means the bridge logic is operational within microseconds of power-on, satisfying the PCI specification's bus-enumeration timing requirements. The 84-pin PLCC remains in production for legacy board-repair and obsolescence-management programs in industrial PCs and point-of-sale terminals.
Recomendado
Embedded CPU Address Decoding & Chip-Select Generation
Embedded designs based on 80186, 68k, PowerPC, and ARM7 processors use the EPM7160ELI84-20 to generate chip-select signals, decode memory maps, and arbitrate shared bus peripherals. Its 160 macrocells and 64 I/Os can implement 8 to 16 independent chip-select decoders with individually programmable wait-state insertion. The deterministic 20 ns tPD delivers consistent chip-select timing regardless of input combinations, critical for zero-wait-state memory interfaces. The non-volatile EEPROM configuration means the memory map is locked-in at power-on without external boot logic, simplifying system bring-up. Industrial temperature grade supports embedded boards deployed in outdoor enclosures, vehicle controllers, and ruggedized military/aerospace subsystems.
Recomendado
Replacing Multiple 74-Series Discrete Logic ICs
The EPM7160ELI84-20 is a classic BOM-reduction tool, replacing 10 to 20 discrete 74LS, 74HC, 74FCT, or 74ABT logic packages with a single programmable device in legacy PCBs. Each macrocell can implement a sum-of-products equation equivalent to a 74-series PAL/GAL, and the wide input gating (up to 36 inputs per macrocell in MAX 7000) supports complex combinatorial functions. The 5V VCC directly replaces 74LS/74HC designs without supply changes. JTAG ISP allows engineers to fix logic bugs, add features, or respin functionality without reworking the PCB - a key advantage for legacy products still in service but out of production. This application is especially valuable in aerospace, medical-device, and industrial-automation fields where board re-spins are expensive or require regulatory re-certification.
Recomendado
Power-Up Sequencing & Reset Distribution
In multi-rail systems requiring careful power-up sequencing (ASICs, FPGAs, microcontrollers, and analog ICs), the EPM7160ELI84-20 provides deterministic sequencing logic that becomes active immediately upon VCC ramp thanks to its non-volatile EEPROM configuration. The device can monitor up to 64 input rails or enable signals, generate programmable delay chains via its macrocell flip-flops, and drive sequencing outputs with 20 ns precision. Compared to a sequencer IC, the EPM7160ELI84-20 allows full customization of timing, polarity, and dependencies without a separate firmware step. Industrial temperature rating and 5V tolerance suit it for ATX, telecom-shelf, and industrial-PC power architectures where 5V standby rails are standard.

Principais diferenciais
- Industrial temperature grade at 5V (vs EPM7160ELC84-20)

- Non-volatile EEPROM vs SRAM-based FPGAs (vs Cyclone FPGAs)
Notas de projeto
The EPM7160ELI84-20 requires a stable 5.0V (4.75-5.25V) supply with sufficient decoupling. Place a 0.1uF ceramic decoupling capacitor as close as possible to each VCC pin (the 84-PLCC has multiple VCC/GND pairs distributed around the package), plus a single 10uF tantalum or aluminum bulk capacitor at the board entry point. The device's I/O pins source/sink up to 25 mA per pin (typical), so total VCC current can exceed 200 mA in heavily-loaded designs - verify your regulator has adequate headroom. Avoid placing the CPLD near high-current switching nodes (relays, motor drivers) to minimize supply-rail noise coupling into the 5V rail.
For 84-pin PLCC designs, use a PLCC socket (machine-pin or low-profile) to allow in-system programming and easy replacement of obsolete parts. Keep JTAG signals (TDI, TDO, TMS, TCK) accessible via a 2x5 0.1-inch header for ByteBlasterMV/USB-Blaster connection during development and field updates. Route JTAG traces away from high-speed switching signals and keep them under 6 inches to maintain signal integrity. For the 84-PLCC, the recommended land pattern is JEDEC MS-018 - follow this exactly to ensure socket compatibility. Add a ground plane beneath the device to provide low-impedance return paths for the high-speed I/O switching currents.
Estimated: When migrating from EPM7160ELI84-20 (industrial -40C to +85C) to EPM7160ELC84-20 (commercial 0C to +70C), confirm the target environment stays within the C-grade temperature range or the device lifetime will be severely reduced. Do not assume the MAX 7000 family is pin-compatible with MAX 7000S - bitstream files are not interchangeable even though packages match; recompile in Quartus for any -S variant. The 5V I/Os cannot directly drive 3.3V logic above their VIH level without level shifters or resistor dividers. When designing for new products in 2026, prefer MAX II (EPM240/570) or MAX V (5M80ZE64) for active lifecycle and lower power, reserving MAX 7000 for legacy board-repair applications.
