EPM5130WC-1 Overview
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell blocks on a single die with a central interconnect matrix. CPLDs sit in the programmable logic hierarchy above simple PLDs and below FPGAs; they offer predictable timing, deterministic pin-to-pin delays, and instant-on configuration from on-chip EEPROM/EPROM, which makes them especially valuable in address decoding, peripheral control, and bus-interface bridging where sub-nanosecond timing guarantees are required.
The EPM5130WC-1 supports up to 100 user I/O through the QFP package, integrates 128 macrocells across multiple Logic Array Blocks (LABs), and provides a programmable interconnect array that maintains consistent timing regardless of how a design is placed. Its UV-erasable windowed package allows iterative reprogramming during development cycles. The MAX 5000 architecture is fabricated on a CMOS EPROM process, providing non-volatile configuration storage.
Architecturally, the MAX 5000 family uses a programmable AND/OR array feeding a configurable macrocell register that can be configured as combinational or registered output. Each macrocell includes a flip-flop with programmable clock, clear, and preset controls. The deterministic interconnect fabric guarantees a fixed propagation delay independent of routing density, simplifying static timing analysis.
Typical applications include bus-interface glue logic, peripheral address decoding, state-machine controllers, and legacy industrial control systems that require UV-reprogrammable non-volatile logic. The ceramic QFP package is also suited to military and aerospace-grade designs with MIL-STD-883B screening variants available in the MAX 5000 family.
When designing with the EPM5130WC-1, account for its 40 ns propagation delay when targeting high-speed bus interfaces and provide proper decoupling on all VCC pins. UV windowed ceramic packages require a label covering the quartz window after programming to prevent accidental erasure from ambient light exposure.

Typical Applications
EPM5130WC-1 is suitable for 6 applications: Bus Interface Glue Logic, State Machine Controllers, Peripheral Address Decoders, Legacy Industrial Control Systems, Military and Aerospace Avionics, Retro Computing and Vintage Hardware Restoration.
Bus Interface Glue Logic
The EPM5130WC-1's 128 macrocells and deterministic 40 ns propagation delay make it well suited for legacy bus-interface glue logic such as address decoding, chip-select generation, and bus-width conversion in VMEbus, ISA, or Motorola 68000 systems. Its 100-pin ceramic QFP package provides ample I/O for multiple parallel bus signals while the UV-erasable window supports iterative prototyping. The MAX 5000 family's deterministic interconnect ensures timing margins hold regardless of design placement. Engineers use this part to consolidate discrete TTL glue logic into a single programmable device, reducing board area and improving reliability in industrial control and instrumentation systems.
Recommended
State Machine Controllers
The EPM5130WC-1's macrocell architecture with programmable flip-flops, clock, clear, and preset controls is ideal for implementing multi-state control logic in industrial automation and process control equipment. With 128 macrocells the device can host several cooperating state machines or one large controller with dozens of states. The 50 MHz maximum clock frequency supports real-time control loops in legacy systems. UV-erasability allows field upgrades of state-machine firmware by erasing and reprogramming without removing the device from the board, a significant advantage for factory-floor equipment where downtime is costly.
Recommended
Peripheral Address Decoders
The EPM5130WC-1 is widely used for peripheral address decoding in legacy embedded systems where memory-mapped I/O requires combinational decoding across wide address buses. Its 100 user I/O pins comfortably accommodate 24-bit address buses plus multiple chip-select outputs. The 40 ns propagation delay adds directly to memory-access timing budgets, so engineers must verify that downstream peripherals tolerate this latency. The deterministic MAX 5000 interconnect guarantees consistent decoding delays across all address ranges. The ceramic package variant supports high-reliability applications in aerospace and military systems where MIL-STD-883B screening is required.
Recommended
Legacy Industrial Control Systems
The EPM5130WC-1 is a preferred drop-in part for maintaining legacy PLCs, CNC controllers, and process-control equipment originally designed around MAX 5000 CPLDs. Its UV-erasable ceramic package allows field technicians to update logic by erasing and reprogramming in-circuit (with proper window access). The 128 macrocells match the original design density, and the 100-pin QFP footprint matches existing PCBs. Designers should note that modern replacement parts (MAX V, MAX 10) require PCB redesign and are not drop-in compatible. Sourcing through obsolete-parts distributors is the standard approach for repairs.
Recommended
Military and Aerospace Avionics
The EPM5130WC-1 in ceramic QFP packaging supports military and aerospace applications where radiation tolerance, MIL-STD-883B screening, and extended temperature ranges are required. The Altera MAX 5000 family includes 883B variants (EPM5130GM883B) qualified for defense applications. The 128 macrocells provide sufficient logic for sensor interface consolidation, navigation-computer glue logic, and display-driver interfacing. UV-erasability supports pre-launch logic updates in development programs. Designers must verify MIL-PRF-38535 QML qualification status with current distributors before specifying for flight hardware.
Recommended
Retro Computing and Vintage Hardware Restoration
The EPM5130WC-1's UV-erasable ceramic QFP package makes it a natural choice for retro-computing enthusiasts restoring vintage workstations, minicomputers, and arcade systems that originally used MAX 5000 CPLDs. The windowed package allows hobbyists to experiment with logic designs and erase/reprogram repeatedly. The 128-macrocell density matches the original design sizes used in 1980s and 1990s computers. Restoration projects can source these obsolete parts through surplus distributors like FPGAkey and Jotrin. Note that modern retro-computing FPGA projects typically use larger modern devices programmed as drop-in replacements, but authentic restorations prefer the original part.

- Commercial vs military temperature grade (vs EPM5130GM883B)
Design Notes
The EPM5130WC-1 requires a stable 5V VCC supply (verify exact nominal voltage against the MAX 5000 datasheet, marked [DATA_NEEDED]). Place 0.1 uF ceramic decoupling capacitors close to every VCC pin and add a 10 uF tantalum bulk capacitor near the device. The ceramic QFP package has multiple VCC and GND pins; all must be connected. Insufficient decoupling on the older CMOS EPROM process can cause intermittent logic errors during configuration reads.
After programming the EPM5130WC-1, ALWAYS cover the quartz window with an opaque label. Ambient UV light (including sunlight and fluorescent lighting over extended periods) can partially erase the EPROM cells, causing logic corruption. This is the single most common failure mode for UV-erasable CPLDs in field-deployed equipment. Use a high-quality UV-opaque label rated for the device's operating temperature range.
The 100-pin ceramic QFP package requires careful PCB layout for reliable soldering and rework. Use a dogbone fanout pattern with 0.2 mm traces and 0.5 mm pitch vias. Provide a grounded copper pour under the package for thermal dissipation and EMI shielding. The ceramic package has a higher thermal mass than plastic, so reflow profiles must reach 220C peak with appropriate preheat soak (60-90 seconds at 150-200C) to avoid thermal shock.
The MAX 5000 family uses deterministic interconnect with fixed 40 ns propagation delay regardless of internal routing. Designers can rely on static timing analysis without worrying about placement-dependent delays. However, output drive strength is limited; for heavily loaded buses (more than 4-5 loads) add external buffers. Inputs are TTL-compatible at 5V VCC; do not exceed VCC + 0.5V on any input pin to avoid latch-up.
Estimated: At 50 MHz toggle frequency with all 128 macrocells switching at typical 15 pF load, the EPM5130WC-1 dissipates approximately 0.5-1W. The ceramic QFP package provides good thermal conductivity to PCB copper. Ensure adequate ground-plane copper area (at least 1 square inch) under the package to keep junction temperature within the commercial 0C to +70C range. For industrial or military grades, verify derating with the EPM5130QC-1 or EPM5130GM883B datasheet.
Compliance Information
The EPM5130WC-1 is an obsolete ceramic-windowed CPLD. Compliance status (RoHS, REACH, lead-free) was not available in the verified distributor data and is marked as unknown. Ceramic windowed packages often contain leaded terminations; verify with the manufacturer before specifying for new designs in RoHS-regulated regions. AEC-Q100 is not applicable because this is a programmable logic device, not an automotive-grade IC.
