A Complex Programmable Logic Device (CPLD) is a non-volatile, instantly-on semiconductor that combines multiple PAL-like macrocell blocks with a programmable interconnect matrix on a single die. CPLDs sit between discrete TTL/CMOS glue logic and larger FPGAs in the programmable-logic hierarchy: PLD -> CPLD -> FPGA -> programmable logic. They are valued for deterministic timing, zero-configuration latency, and high pin-to-pin drive strength, which makes them ideal for address decoding, bus interfacing, and state-machine replacement in legacy industrial designs.
Key features of the EPM5192AGC84-20 include 192 macrocells (delivering up to ~7,500 usable gates), 64 bi-directional I/O pins organized into 4 I/O banks, 7 dedicated global input pins (GCLK, OE1, OE2, OE3, OE4, CLR, PRE), in-system UV-erase window (ceramic package), and 5-Volt CMOS I/O compatible with TTL levels. The "-20" speed grade corresponds to tPD = 20 ns and fMAX = 66.7 MHz.
The device is built on Altera's classic MAX (Multiple Array matriX) architecture, which arranges macrocells into Logic Array Blocks (LABs) connected by a continuous programmable interconnect. The ceramic CPGA package is hermetic and UV-transparent, allowing erasure under a UV lamp; an OTP window is included for production programming. The design supports both combinatorial and registered logic with per-macrocell D/T/JK flip-flop configuration.
Typical applications include legacy bus-interface glue logic in industrial controllers, address decoding for microprocessor and DSP systems, peripheral replacement (decoders, multiplexers, state machines), and prototype-to-production migration where deterministic timing and instant-on behavior are required. Its 84-pin CPGA is also well suited to through-hole industrial backplanes and military-style card cages where ceramic packaging is preferred.
When designing with this part, verify that the CPGA land pattern matches your socket or PCB footprint; ceramic CPGA sockets are specialty items and may have long lead times. For new designs, modern Altera/Intel MAX II or MAX V devices in PLCC/QFP packages are recommended, but the EPM5192AGC84-20 remains the canonical drop-in for legacy systems requiring UV erase.

典型應用
EPM5192AGC84-20 適用於 6 應用s: Legacy Industrial Bus Interface Glue Logic, Microprocessor Address Decoding, Peripheral Replacement (Decoders / MUX / State Machines), Prototype-to-Production Migration Designs, Test & Measurement Backplane Controllers, Legacy Aerospace & Defense Subsystems.
Legacy Industrial Bus Interface Glue Logic
The EPM5192AGC84-20's 192 macrocells and 64 I/O pins are well-matched to legacy industrial bus-interface glue logic. Its 66.7 MHz fMAX and 20 ns tPD comfortably decode ISA, VME, and PC/104 address spaces, while the 84-pin CPGA hermetic package withstands factory-floor temperature cycling and vibration. Compared with discrete 74LS/74F glue logic, a single EPM5192 replaces 10-20 small-scale integration packages, reducing board area and improving noise immunity through deterministic pin-to-pin timing.
推薦
Microprocessor Address Decoding
The EPM5192AGC84-20 excels at microprocessor address decoding, where its 192 macrocells can implement multi-bank chip-select logic for 32-bit and 64-bit address spaces. With 20 ns tPD the part sits comfortably between CPU address latch and peripheral enable pins on 25-33 MHz 68000/i386 systems, and the 7 dedicated inputs accept global clock, reset, and bus-control signals. The ceramic CPGA package is preferred in military/aerospace SBCs that demand hermeticity and known-provenance parts.
推薦
Peripheral Replacement (Decoders / MUX / State Machines)
Designers use the EPM5192AGC84-20 to consolidate decoder, multiplexer, and state-machine functions into a single instant-on device, replacing 5-15 discrete 74xx/54xx TTL packages. The MAX 5000 architecture's registered macrocells allow per-bit D, T, JK, or SR flip-flop configuration, and the deterministic 20 ns delay eliminates race conditions that plague discrete-logic equivalents. The 64 I/O pins support up to 32-bit datapath muxes, ideal for legacy parallel-port, SCSI, and GPIB interface cards.
推薦
Prototype-to-Production Migration Designs
The EPM5192AGC84-20's UV-erasable window allows engineers to iterate designs during prototype development, then mask-program the final production units. This is valuable for low-volume industrial and aerospace systems where NRE mask charges are amortized over hundreds rather than millions of units. With 192 macrocells and 66.7 MHz fMAX, the part covers the majority of mid-complexity glue-logic designs, and the ceramic CPGA package is accepted by many defense/aerospace procurement specifications.
推薦
Test & Measurement Backplane Controllers
In test-and-measurement instrumentation, the EPM5192AGC84-20's deterministic timing and 64 I/O pins make it ideal for VXI, PXI, and proprietary instrument backplane controllers. The 7 dedicated inputs (clock, output-enable, clear, preset) simplify synchronisation to a backplane 10 MHz or 100 MHz reference, and the 84-pin CPGA socketable form factor eases field replacement. Its instant-on behavior eliminates FPGA configuration timeouts that would otherwise complicate production test sequencing.
推薦
Legacy Aerospace & Defense Subsystems
The EPM5192AGC84-20's ceramic CPGA hermetic package and established Altera MAX 5000 pedigree make it a documented source for legacy aerospace and defense subsystems that must use form-fit-function replacements for end-of-life parts. Its 192-macrocell density covers most 1990s-era mission-computer interface logic, and the part is supported by established independent distributors with full traceability documentation (date code, lot, country of origin). For new defense designs, however, MAX 10 (10M02, 10M08) is preferred.

設計說明
The 84-pin Ceramic Pin Grid Array (CPGA, package code WPGA) requires a specialty PGA socket or a custom through-hole PCB land pattern. Do not assume standard 0.1" headers will accept the pin grid - the PGA pin pitch is 2.54 mm (0.1") but the array is 12x12 with the center positions depopulated, not a single inline or dual-inline package. For prototype work, use a 3M or Tyco/Amp PGA socket (84-position, machined-pin); for production, a custom PCB footprint with plated through-holes is required.
When laying out the EPM5192AGC84-20, place at least one 0.1 uF decoupling capacitor per VCC/VCCIO pin pair, positioned within 5 mm of the PGA pins. Add bulk 10-47 uF tantalum or aluminum capacitors near the device. The CPGA package has multiple VCC and GND pins distributed around the perimeter - review the MAX 5000 family datasheet pin table and ensure all VCC pins are decoupled. Programmed CPLDs draw significant dynamic current during simultaneous switching outputs; without proper decoupling this will appear as ground bounce and degrade fMAX margin.
The UV-erasable window must be covered with an opaque label during production use to prevent accidental erasure from ambient UV light (sunlight, fluorescent lamps, or UV-A curing stations). Use a standard ESD-protective label or 3M polyester tape. Erasure requires approximately 20-30 minutes under a 12,000 uW/cm^2 UV lamp at 253.7 nm; do not exceed recommended exposure or the EPROM cells may be damaged. After erasure, the device returns to all-ones state and must be reprogrammed before use.
Estimated: at 66.7 MHz clock with 64 simultaneously-switching outputs, the EPM5192AGC84-20 can draw transient currents of approximately 200-400 mA on VCC. Use wide VCC/GND traces (at least 0.5 mm) and multiple vias to inner VCC/GND planes. For long PCB traces (>50 mm), add 22-33 ohm series damping resistors to suppress transmission-line ringing. The 7 dedicated inputs (GCLK, OE1-OE4, CLR, PRE) should be terminated with 10 kohm pull-ups if unused, to prevent spurious clock/reset events.
合規資訊
RoHS and REACH compliance status not stated in available web data; the ceramic CPGA package with lead-bearing solder termination is generally considered NOT RoHS-compliant, but this part was originally designed before RoHS and is supplied as legacy/new-old-stock. For RoHS-compliant alternatives, choose modern Altera/Intel MAX II or MAX V plastic packages.
