EPM5128GM883B Ringkasan

The Altera EPM5128GM883B is a UV-erasable programmable logic device (EPLD) from the MAX 5000 family, featuring 128 macrocells, 52 I/O lines, 7 dedicated inputs, and a propagation delay of 55 ns, housed in a ceramic PGA-883 package and qualified to MIL-STD-883 Class B. The device is organized as 8 Logic Array Blocks (LABs) interconnected by a Programmable Interconnect Array (PIA), supports one external clock input, and operates from a single 5 V supply using CMOS technology.

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.
