EPM5128GC-2 Übersicht
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic IC that bridges the gap between discrete 74-series glue logic and larger FPGAs, integrating PAL/GAL-like macrocells with a wide AND-OR logic plane to implement combinational and registered logic. The MAX 5000 family uses ultraviolet-erasable EPROM cells for configuration and is considered a predecessor of the modern MAX 7000/MAX II families; it sits within the broader hierarchy of programmable logic devices (PLDs) -> CPLDs -> non-volatile logic ICs -> digital semiconductors.
Key features include 2,500 gates, 128 macrocells, 68 programmable I/O pins, an enhanced -2 speed grade, and a 5V VCC tolerance suitable for legacy TTL/CMOS interfaces. Designers value the deterministic timing, low power consumption, and one-time programmable security for production designs.
Technically, the EPM5128GC-2 leverages Altera's classic MAX architecture with buried macrocells and a programmable interconnect array (PIA) that routes sum-of-products terms across the device. Configuration is stored in UV-erasable EPROM cells, so the device is one-time programmable in production and erasable only with quartz-window exposure. Operating junction temperature spans 0C to +70C (commercial grade), and the ceramic PGA package (GC suffix) offers robust thermal performance for through-hole or socketed mounting.
Typical applications include industrial 5V bus interface glue logic, legacy peripheral controllers (e.g., address decoding for ISA/VME), state-machine replacement in motor control, and retrofit designs that must match existing 5V CPLD footprints. It is also widely used in educational kits and aerospace/military programs where Altera's MAX 5000 silicon remains a long-lifecycle part.
Designers should note that the EPM5128GC-2 requires a 5V supply rail and is not 3.3V tolerant; I/O banks share the VCC supply, so mixed-voltage interfacing demands external level shifters. For new designs, modern MAX II or MAX V equivalents in surface-mount packages are recommended, but the EPM5128GC-2 remains invaluable for maintenance and lifecycle-extension of legacy boards.
This page synthesizes distributor pricing, same-brand MAX 5000 alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers evaluate the EPM5128GC-2 for both legacy support and cost-down retrofits.

Typische Anwendungen
EPM5128GC-2 ist geeignet für 6 Anwendungs: 5V Industrial Glue Logic Replacement, Legacy ISA/VME Address Decoding, State-Machine Replacement in Motor Control, Aerospace & Defense Long-Lifecycle Boards, Educational Logic-Design Kits, Retrofit / Drop-in Maintenance of Legacy Boards.
5V Industrial Glue Logic Replacement
The EPM5128GC-2 is a strong fit for 5V industrial glue logic replacement because it integrates 128 macrocells and 2,500 usable gates in a single 68-pin PGA package, consolidating what previously required several 74LS/74HC chips. Its 50 MHz toggle frequency (per the -2 speed grade) and 5V VCC tolerance let it interface directly with legacy TTL/CMOS buses without level shifters. Engineers deploy it in programmable address decoders, bus arbitrators, and custom peripheral controllers on ISA, VME, and STD backplanes where deterministic timing and 5V rails are mandatory.
Empfohlen
Legacy ISA/VME Address Decoding
The EPM5128GC-2 excels at ISA/VME address-decoding tasks because its 128 macrocells can implement multiple sum-of-products decoders in parallel, supporting 16- or 24-bit address-bus decoding with chip-select outputs. The MAX 5000 deterministic timing (tPD ~25 ns typical at -2 grade) avoids the metastability hazards of asynchronous logic. Its 5V I/O and 68-pin PGA footprint match legacy backplane daughtercards, allowing drop-in repair or capacity expansion of existing boards.
Empfohlen
State-Machine Replacement in Motor Control
The EPM5128GC-2 is well-suited for state-machine replacement in motor-control subsystems because it can hold multiple Moore/Mealy state machines, PWM sequencers, and fault-handling logic in a single non-volatile device. Its 5V VCC matches industrial H-bridge driver interfaces, and the 128 macrocells easily absorb encoder decoding, commutation tables, and watchdog functions. The UV-erasable EPROM gives one-time-programmable security that prevents firmware cloning in production controllers.
Empfohlen
Aerospace & Defense Long-Lifecycle Boards
The EPM5128GC-2 remains in demand for aerospace and defense programs because the MAX 5000 family has established long-lifecycle status and qualified BOMs in legacy avionics, ground-station, and radar subsystems. Per distributor catalog data, the part is still listed for retrofit and maintenance contracts despite Altera's obsolete classification. Engineers use it to repair 20- to 30-year-old boards where PCB redesign is not feasible and 5V logic compatibility is mandatory.
Empfohlen
Educational Logic-Design Kits
The EPM5128GC-2 is a popular teaching vehicle in university logic-design and computer-architecture labs because its 128 macrocells let students implement complete CPUs, ALUs, and bus arbiters in a single non-volatile device. The 68-pin PGA is easy to socket on a breadboard-style training board, and UV erasure makes re-use simple between cohorts. Per Altera legacy notes, MAX 5000 family devices remain supported in Altera/Intel MAX+PLUS II design software for educational continuity.
Empfohlen
Retrofit / Drop-in Maintenance of Legacy Boards
The EPM5128GC-2 is the canonical maintenance part for industrial automation, CNC controllers, and medical-imaging boards originally designed around the MAX 5000 family. Its 68-pin PGA footprint matches legacy sockets, and the 5V VCC and TTL-compatible I/O eliminate PCB rework. When the original CPLD fails in the field, swapping in a fresh EPM5128GC-2 (or its -1/-0 speed-grade siblings) restores the board without retooling, preserving long-life-cycle assets and avoiding costly retrofits.

Wichtigste Unterscheidungsmerkmale
- Highest macrocell count in the MAX 5000 family (vs. EPM5064LC-2)
- Highest speed grade among EPM5128GC variants (vs. EPM5128GC-1)
- Ceramic PGA package with UV-erasable window (vs. EPM5128GC-1)
Designhinweise
Estimated: at 50 MHz toggle on all 128 macrocells with 50% utilization, the EPM5128GC-2 draws on the order of 200-300 mA from a 5V rail. The 68-pin ceramic PGA exposes all VCC/GND pins for low-impedance distribution; use at least 4 VCC pins and 4 GND pins, decouple each pair with 0.1 uF + 10 uF bulk caps placed within 5 mm of the package. Avoid powering from a 3.3V rail — the device is not 3.3V tolerant and will not program reliably below 4.75V.
Use a PGA socket (e.g., machined-pin or PCB-headers) when designing serviceable boards, since the ceramic PGA is not field-solderable. Route I/O signals on inner layers with controlled impedance only if the design drives high-speed edges; for 50 MHz operation standard 50 ohm microstrip or stripline is acceptable but not mandatory. Keep programming pins (DCLK, CONF_DONE, nCONFIG, nSTATUS, DATA0) accessible for in-system programming via Altera ByteBlaster/MV-compatible tools.
Do not assume the EPM5128GC-2 is in-system reprogrammable — it uses UV-erasable EPROM and the ceramic 'GC' package has a quartz window that requires 20-30 minutes of UV exposure for erasure. Plastic non-windowed 'PC' variants are truly one-time programmable. Also note that MAX 5000 design files use legacy MAX+PLUS II syntax; newer Quartus projects will not synthesize this part, so retain an archived MAX+PLUS II toolchain for legacy support.
Compliance-Informationen
Specific RoHS/REACH status not stated in current distributor data for the EPM5128GC-2 marking; MAX 5000 family is a legacy Altera product line and may use lead-bearing terminations. Verify compliance with the supplier before RoHS-restricted deployment.
