EPM5128GM883B Présentation
An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic IC that combines AND/OR array logic with macrocell flip-flops. EPLDs sit at the bottom of the programmable logic hierarchy: macrocell -> CPLD -> programmable logic -> digital IC. Unlike SRAM-based FPGAs that require a configuration ROM, EPLDs retain their logic on power-down and boot in microseconds, which is critical for power-on control logic and glue logic replacement.
Key features of the EPM5128GM883B include 128 macrocells of user logic, 59 total inputs (52 user I/O + 7 dedicated), 8 LABs, a PIA that distributes signals between every LAB with uniform delay, and 55 ns pin-to-pin propagation delay. The MAX 5000 architecture provides predictable timing because every signal path traverses the same PIA, simplifying static timing analysis versus SRAM FPGA fabric.
Technically, the EPM5128GM883B uses UV-erasable EPROM cells for configuration retention and CMOS I/O for low static power. The GM883B suffix designates a ceramic pin grid array package and MIL-STD-883 Class B processing for military and aerospace programs. The dedicated clock pin feeds a global clock network that drives every macrocell register with low skew.
Typical applications include military and aerospace avionics, industrial control glue logic, bus interface adapters, state-machine controllers, and address decoding for microprocessor systems. Designers select the EPM5128GM883B when a moderate-density, non-volatile, deterministic-timing logic device is required for harsh-environment programs.
When designing with this part, budget for a UV eraser window on the top of the package because the device must be exposed to UV-C light for ~20 minutes to erase. Also verify that 55 ns propagation delay meets the system timing budget; if not, consider the -2 speed grade variant with 45 ns delay.

Applications typiques
EPM5128GM883B convient pour 6 applications: Military Avionics Control Logic, Industrial Control Glue Logic, Bus Interface Adapter, Aerospace Satellite Subsystems, State Machine Controllers, Address Decoding Logic.
Military Avionics Control Logic
The EPM5128GM883B fits military avionics because its MIL-STD-883 Class B qualification, -55C to +125C operating range, and ceramic PGA-883 package meet the harsh-environment requirements of airborne platforms. Its 128 macrocells provide enough logic density for flight-control glue logic, sensor interface conditioning, and discrete-to-bus conversion circuits. The 55 ns propagation delay is acceptable for sub-MHz control loops where deterministic timing matters more than raw speed.
Recommandé
Industrial Control Glue Logic
In industrial automation systems, the EPM5128GM883B replaces discrete TTL/CMOS glue logic arrays with a single programmable device. Its 52 I/O and 7 dedicated inputs handle multiple sensor inputs, control outputs, and bus interfaces. UV-erasable programmability allows field reconfiguration with a UV eraser, which is valuable for long-lifecycle industrial programs that span decades. The CMOS technology keeps quiescent current low for 24V-powered control cabinets.
Recommandé
Bus Interface Adapter
The EPM5128GM883B serves as a bus interface adapter for legacy microprocessor systems, providing address decoding, wait-state generation, and protocol translation between incompatible bus standards. Its 128 macrocells handle full 24-bit address decoders with chip-select outputs and handshake logic. The PIA architecture delivers uniform interconnect delay, simplifying worst-case timing calculations for asynchronous bus cycles in 68k and x86 legacy platforms.
Recommandé
Aerospace Satellite Subsystems
The EPM5128GM883B suits satellite subsystems requiring radiation-tolerant characteristics through its MIL-STD-883 Class B screening and ceramic hermetic PGA-883 package. Its 128 macrocells are sufficient for telemetry encoding, command decryption glue logic, and power-system sequencing in low-earth-orbit and geosynchronous platforms. UV-EPROM configuration is non-volatile and immune to configuration upsets that affect SRAM-based FPGAs in radiation environments.
Recommandé
State Machine Controllers
Designers use the EPM5128GM883B to implement complex state machines for protocol handlers, sequencers, and finite-state control systems. Its macrocell flip-flops with product-term-based logic allow state encoding and transition equations to be implemented in a single device without external MSI glue. The deterministic PIA delay ensures state transitions occur at predictable intervals, eliminating metastability risks common in asynchronous FPGA designs.
Recommandé
Address Decoding Logic
The EPM5128GM883B excels at memory and peripheral address decoding for 16-bit and 32-bit microprocessors. Its 52 I/O can drive 24-bit address inputs plus multiple chip-select outputs, replacing banks of 74LS138 decoder chips. The 55 ns propagation delay is compatible with 8-12 MHz microprocessors such as the 8086, 68k, and early ARM cores where propagation delay is a small fraction of the bus cycle.

- UV-erasable, non-volatile configuration (vs MAX 7000 SRAM-based CPLDs)
Notes de conception
The PGA-883 package requires through-hole sockets or pin-grid-array PCB footprints with plated through-holes on a 2.54 mm grid. For prototype builds, use a machined-pin PGA socket to allow device removal for UV erasure. For production builds, solder the device directly to the PCB using wave or hand soldering processes consistent with MIL-STD-883 assembly requirements. Maintain clearance around the ceramic package for thermal expansion and inspect solder joints per IPC-A-610 Class 3.
Programming the EPM5128GM883B requires a UV eraser because the device uses UV-erasable EPROM cells. A quartz window on the top of the PGA-883 package allows UV-C exposure for approximately 20 minutes for full erasure. Standard room fluorescent lighting does not erase the device, but cover the window during programming to prevent accidental erasure. Verify programming voltages and timing against the Altera MAX 5000 programming specification.
The EPM5128GM883B operates over -55C to +125C case temperature in military applications. Decoupling capacitors (one 0.1 uF ceramic per VCC pin and one 10 uF tantalum bulk per supply) must be placed within 5 mm of each VCC pin to suppress switching noise. The PGA-883 ceramic package provides low thermal resistance and can dissipate CMOS switching power without a heatsink in most designs, but verify junction temperature with derating curves for high-utilization designs.
Informations de conformité
PGA-883 ceramic military package contains lead-based solder terminators and is not RoHS compliant. MIL-STD-883 Class B qualification per suffix 883B. Not applicable for AEC-Q100 (military/aerospace grade, not automotive).
