EPM5128GC2 Présentation
An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device that combines the architecture of a PAL (Programmable Array Logic) with an EPROM-style erasable cell, allowing engineers to implement glue logic, state machines, address decoding, bus interfacing, and other random-logic functions in a single chip. Within the broader programmable logic hierarchy, EPLDs sit between simple SPLDs/PALs and higher-density CPLDs and FPGAs, offering predictable timing, instant-on behavior, and zero in-system configuration overhead because the logic is stored in on-chip EPROM cells.
Key features of the EPM5128GC2 include 128 macro cells organized into 8 Logic Array Blocks (LABs) of 16 macro cells each, 16 dedicated inputs, 64 I/O pins, a programmable interconnect array (PIA), a 5V VCC supply with 5V-tolerant I/O, a maximum internal toggle frequency of 50 MHz, propagation delays measured in tens of nanoseconds, and a programmable macrocell flip-flop with selectable D/T/JK/SR behavior. Per the datasheet, the part supports both combinatorial and registered logic with dedicated clear, preset, and clock controls per macro cell.
The MAX 5000 architecture uses a sum-of-products AND/OR plane feeding a programmable macrocell register, with a global PIA that routes signals between LABs. This architecture provides fast, deterministic pin-to-pin timing that is independent of logic placement, which is highly desirable for asynchronous glue logic and bus interface designs. Unlike SRAM-based FPGAs, the EPM5128GC2 holds its configuration without external boot memory and is ready to drive outputs within nanoseconds of VCC ramp.
Typical applications include legacy 5V bus-interface and address-decoding logic in industrial control backplanes, prototyping adapters and test fixtures where the ceramic PGA windowed package allows UV erasure and reuse, MIL/aerospace and high-reliability systems that still require mature 5V CPLD logic, replacement of discrete 74LS/74F glue-logic gates, and as a bridge between 5V and 3.3V buses using its 5V-tolerant I/O structure.
When designing with this device, the ceramic PGA windowed package requires a UV eraser for reprogramming, so high-volume production generally migrates to one-time-programmable (OTP) plastic package variants such as EPM5128LC, while the GC2 remains the preferred choice for engineering development, breadboarding, and long-life military/aerospace programs.

Applications typiques
EPM5128GC2 convient pour 6 applications: 5V Bus Address Decoding and Glue Logic, Industrial Control Backplane Logic, Prototype and Development Adapter Logic, MIL/Aerospace and High-Reliability Systems, Legacy TTL/CMOS Logic Consolidation, 5V-to-3.3V Bus Bridge / Level Shifting Helper.
5V Bus Address Decoding and Glue Logic
The EPM5128GC2 is well suited to legacy 5V bus address decoding and discrete glue-logic replacement. Its 128 macro cells and 64 I/O pins let a designer replace dozens of 74LS/74F packages with one part, while the deterministic AND/OR + PIA architecture gives predictable pin-to-pin propagation delay independent of logic placement, which is essential for asynchronous decoder paths. The 5V VCC and 5V-tolerant I/O match legacy 5V microprocessors and peripheral buses (8086, 68K, VME) without level shifters. Place the device close to the buffers it drives to keep stubs short, and use the dedicated clock/clear/preset per macro cell for synchronous control logic.
Recommandé
Industrial Control Backplane Logic
In industrial control backplanes the EPM5128GC2 implements handshaking, interrupt steering, and bus arbitration logic on 5V VME, VXI, or proprietary parallel backplanes. The on-chip EPROM configuration means the device is ready to drive outputs within nanoseconds of VCC ramp, with no external boot PROM and no FPGA bitstream loading latency - critical for hot-swap and fault-recovery scenarios. The 16 dedicated inputs simplify capture of backplane control signals (BBSY, BG, IRQ lines). The ceramic PGA package tolerates the wider industrial temperature range and provides the mechanical robustness required for backplane sockets.
Recommandé
Prototype and Development Adapter Logic
The windowed ceramic PGA package of the EPM5128GC2 allows UV erasure and reprogramming, making it ideal for engineering development boards, prototype adapters, and test fixtures where the design is iterated frequently. Engineers can implement state machines and bus-protocol engines, verify them on the bench, erase with a UV eraser, and re-program within minutes - a workflow that is not possible with one-time-programmable plastic parts. 128 macro cells accommodate substantial logic density (a full 16-bit state machine plus bus-master logic) in a single chip. Use a low-profile PGA socket so the UV window stays accessible without removing the part.
Recommandé
MIL/Aerospace and High-Reliability Systems
Aerospace and military programs that were qualified on the Altera MAX 5000 family continue to specify the EPM5128GC2 for line-replaceable units, radar interfaces, and avionics data buses because the ceramic PGA package meets the screening and hermeticity requirements of legacy MIL specifications. The mature CMOS EPROM process has decades of field reliability data, and the deterministic timing simplifies worst-case timing analysis required by DO-254 and MIL-HDBK-454. Maintain a documented last-time-buy strategy with qualified brokers (Jotrin, Censtry) and trace every lot to its original screening certificate to satisfy configuration management.
Recommandé
Legacy TTL/CMOS Logic Consolidation
The EPM5128GC2 lets designers consolidate dozens of 74LS, 74F, 74HC, and 4000-series SSI/MSI packages into a single programmable device, saving PCB area, reducing power, and easing documentation. Each of the 128 macro cells can implement D, T, JK, or SR flip-flops with dedicated clock and asynchronous clear/preset, which covers the majority of legacy counter, shift-register, and latch functions. The 50 MHz internal frequency is sufficient for most bus-sideband logic (chip selects, wait-state generators, parity logic). Re-target the original TTL schematic into Altera MAX+PLUS II or Quartus legacy libraries to leverage existing design intent.
Recommandé
5V-to-3.3V Bus Bridge / Level Shifting Helper
While the EPM5128GC2 is not a dedicated level shifter, its 5V-tolerant I/O and configurable direction control per pin make it a flexible bus bridge between 5V legacy buses and 3.3V peripherals in mixed-voltage systems. The dedicated inputs and I/O pins can be assigned direction in software at compile time, and the 50 MHz internal frequency easily handles 8-bit/16-bit bus transactions. Use the macrocell flip-flops to register both edges for clean crossing. For higher-throughput designs pair the EPM5128GC2 with a modern 3.3V CPLD or FPGA on the low-voltage side.

Principaux différenciateurs
- UV-erasable ceramic PGA package (vs EPM5128LC (plastic J-lead OTP))
- Pin-for-pin compatibility across the MAX 5128 speed grades (vs EPM5128GC-1 and EPM5128GC (same GC package))
- On-chip EPROM configuration (no external boot) (vs SRAM-based FPGA competitors)
Notes de conception
Do not assume the unsuffixed EPM5128GC can replace the EPM5128GC2 unconditionally: the GC is the commercial baseline speed grade while GC-2 is a specific speed bin per Altera's MAX 5000 datasheet convention. Estimate tPD and fMAX from the datasheet timing tables and re-run static timing analysis in MAX+PLUS II before substituting. Downgrading from -2 to plain GC may violate worst-case timing in asynchronous decoder paths.
Estimated: at 50 MHz toggle across all 128 macro cells with 5V VCC, internal power dissipation for a CMOS EPLD of this density is on the order of 0.5-1.5W. The ceramic PGA GC package offers good thermal conductivity through the pin grid; ensure the socket has a low thermal-resistance path to the PCB ground plane. For long-life programs add a conservative 20-30% derating above the datasheet junction temperature. Actual dissipation depends on toggle rate and output loading - measure on the bench, do not rely solely on this estimate.
Use a low-profile machine-pin PGA socket so the UV window stays accessible for erasure in development flows. Provide a solid ground plane on the component side and a VCC island with 0.1uF ceramic decoupling capacitors within 5 mm of each VCC pin pair. Keep output traces short and series-terminate high-fanout outputs to control ground bounce on the 5V rail. The PGA pin field leaves ample routing channels - plan the breakout so no signal trace passes under the device between socket pins.
Assign clock and asynchronous clear/preset to dedicated macrocell clock/control pins to guarantee predictable skew. For bus interfaces, place registered outputs on pins closest to the bus connector to minimize stub length. Reserve a few I/O pins as JTAG-style test points even if you do not use boundary scan - they are invaluable for oscilloscope probing in legacy systems. Mark U1 as 'UV-erasable' on the silkscreen and add a handling warning to prevent operators from inadvertently wiping the configuration.
Informations de conformité
Ceramic PGA package with quartz window is generally non-RoHS (lead-bearing ceramic and solder finish). RoHS status, REACH status, lead-free status, and conflict-minerals declaration are not explicitly published in current distributor listings and should be confirmed via the manufacturer's certificate of conformance on a per-lot basis.
