EPM5032DI25 - 32-Macrocell MAX 5000 EPLD, 25ns | Altera
MPN: EPM5032DI25 ✗ Cuối đờiEPM5032DI25 Tóm tắt
An EPLD (Erasable Programmable Logic Device) is a non-volatile PLD family that preceded modern CPLDs and FPGAs; it provides PAL-type AND/OR arrays with user-programmable macrocell flip-flops, retaining configuration without external memory. The MAX 5000 sits in the programmable logic hierarchy as: macrocell -> Logic Array Block (LAB) -> Programmable Logic Device -> PLD -> programmable logic -> semiconductor IC. UV-erasable variants in ceramic DIP packages were intended for engineering development and military/industrial programs where in-system reprogrammability by erasing through the quartz window was acceptable.
Key features include 32 macrocells, 16 dedicated output macrocells, 320 product terms, 62.5 MHz fMAX, 5 V single-supply operation, TTL-compatible inputs and outputs, and 24-pin ceramic DIP (DI) packaging rated over the industrial temperature range. The DI suffix denotes a ceramic DIP with a UV-erasable window.
The EPM5032DI25 architecture is implemented in CMOS technology with EPROM storage cells, providing non-volatile configuration and TTL-compatible I/O. Its PAL-type AND-OR logic array with output macrocell flip-flops allows designers to implement both combinatorial and registered functions, while the PIA routes signals between LABs. Operating at 5 V VCC and 25 ns tPD, it delivers deterministic logic-timing suitable for glue logic, bus interfacing, and state-machine replacement in 5 V-only systems.
Typical applications include bus-interface glue logic in 5 V systems, address decoding and wait-state generation in legacy CPU boards, state machines and sequencers in industrial control, TTL-to-TTL signal conditioning, and replacement of multiple discrete PAL/GAL devices in legacy designs. The 25 ns delay supports systems with clock frequencies up to roughly 25-30 MHz synchronous logic.
When designing with this part, ensure the 5 V supply is well-decoupled with 0.1 uF ceramic capacitors placed close to VCC and GND pins, and note that UV-erasable parts require an external EPROM eraser to reprogram; in-system updates are not supported. Designers should also confirm that 5 V tolerance of downstream logic matches TTL thresholds, especially when interfacing to 3.3 V modern devices via level shifters.

Ứng dụng tiêu biểu
EPM5032DI25 phù hợp cho 6 Áp dụngs: Legacy 5V Bus-Interface Glue Logic, Address Decoding and Chip-Select Generation, Industrial State Machines and Sequencers, TTL-to-TTL Signal Conditioning and Level Shifting, Multi-PAL/GAL Replacement and Consolidation, Test and Measurement Front-End Logic.
Legacy 5V Bus-Interface Glue Logic
The EPM5032DI25 is a strong fit for legacy 5V bus-interface glue logic where 32 macrocells, 16 bidirectional I/Os, and 25 ns tPD are needed to consolidate discrete 74LS TTL glue into a single socketed DIP. With 5V TTL-compatible I/O and 320 product terms, it absorbs address decoding, chip-select generation, and wait-state logic that would otherwise occupy multiple 74LS138/139/32 packages. The ceramic DIP with UV window supports iterative prototype reprogramming during development cycles common in industrial controller retrofits.
Được đề xuất
Address Decoding and Chip-Select Generation
The EPM5032DI25 fits address-decoding and chip-select generation tasks in 8/16-bit legacy CPU boards (8086, 68k, Z80) where 7 dedicated inputs plus 16 I/O lines are exactly right for full 16-bit address decoding with multiple bank selects. The 25 ns tPD ensures one-DECode-stage insertion does not break a 25 MHz memory-access budget, and 320 product terms comfortably handle complex AND-OR qualifier logic. The 24-pin ceramic DIP allows easy socket-mounting on backplanes for field-replaceable unit (FRU) serviceability.
Được đề xuất
Industrial State Machines and Sequencers
The EPM5032DI25 is well-suited to industrial state machines and sequencers where 32 macrocells provide flip-flops for 16-state encoding with full Mealy/Moore output decode, plus 24 inputs for sensor and operator-panel switches. The 25 ns tPD gives a worst-case state-transition latency that supports step rates up to about 10 MHz before combinational paths become critical, while 5V TTL I/O interfaces directly to 24V-to-5V opto-isolated industrial I/O. The ceramic DIP is rated for industrial temperature ranges and resists thermal-cycling fatigue in 24/7 factory automation.
Được đề xuất
TTL-to-TTL Signal Conditioning and Level Shifting
The EPM5032DI25 works in TTL-to-TTL signal-conditioning and protocol-translation cards, where 24 inputs handle bus-level signal sampling and 16 outputs drive conditioned signals back to the bus. The 25 ns tPD adds minimal latency to enable/disable or format-conversion paths, and 320 product terms absorb the AND-OR logic of typical bus-arbitration or hand-shaking state machines. The 24-pin ceramic DIP with UV window supports field engineering updates to translation tables without re-spinning the PCB.
Được đề xuất
Multi-PAL/GAL Replacement and Consolidation
The EPM5032DI25 is ideal for replacing multiple discrete PAL/GAL devices (typically 4-6 PAL16L8/PAL20L8 packages) with a single 32-macrocell device, reducing PCB area and improving reliability by removing socketed interconnects. With 320 product terms and 24 inputs, it absorbs the AND-OR planes of typical PAL-GAL banks used in legacy telecom, instrumentation, and test equipment. The ceramic DIP with UV window preserves the development-cycle reprogramming convenience of the original discrete PALs.
Được đề xuất
Test and Measurement Front-End Logic
The EPM5032DI25 fits test and measurement front-end logic where 24 inputs accept parallel sensor data and 16 outputs drive relays, multiplexers, or ADC channel-selects with deterministic 25 ns latency. The 5V TTL-compatible I/O interfaces directly to legacy instrumentation-grade signal chains, while 32 macrocells implement trigger logic, gating, and sequence generators in a single socketed DIP. The UV window supports iterative calibration-algorithm updates during instrument development.

Ghi chú thiết kế
Decouple the EPM5032DI25 VCC pin (pin 24) with a 0.1 uF ceramic capacitor placed within 5 mm of the package, plus a bulk 10 uF tantalum or aluminum electrolytic capacitor on the same 5V rail. The 32-macrocell CMOS core can draw transient current spikes during simultaneous output transitions; without adequate decoupling these spikes can cause ground bounce and false triggering of input pins. A ferrite bead in series with VCC may be added for noise-sensitive analog front-end designs.
Use a 24-pin DIP socket (machined-pin or dual-wipe preferred) rather than soldering the EPM5032DI25 directly to the PCB, because UV erasure requires physical removal of the part. For prototypes, an open-frame ZIF socket accelerates development cycles; for production runs, a closed-frame socket with pin retention is more reliable. Keep trace stubs to unused I/O pins short or remove them entirely to minimize signal reflections on bidirectional pins.
Avoid mixing ceramic DIP UV-erasable parts (DI suffix) with plastic OTP parts (DC suffix) on the same production PCB without verifying that the OTP version is bitstream-compatible: the JEDEC fuse map is identical but UV-erasable parts must be erased before reprogramming, while OTP parts cannot be erased. Also note that the quartz window of ceramic DIP parts is sensitive to ESD and contamination; cover it with opaque tape when not erasing to prevent accidental UV exposure from fluorescent lighting or sunlight that can corrupt the configuration over time.
The 24 dedicated-input pins and 16 bidirectional I/O pins are TTL-compatible, not CMOS-compatible with 5V inputs from 3.3V logic without a level shifter. When interfacing to 3.3V modern microcontrollers, add a 74LVC245 or similar bidirectional level translator between the 3.3V device and the EPM5032DI25; do not rely on the 5V TTL inputs to safely accept 3.3V signals over the full temperature range. Also terminate long bus traces with 220-330 ohm series resistors to dampen ringing on the 25 ns-class outputs.

Compliance status not stated in verified distributor data. The ceramic DIP package predates most RoHS conversion programs and may contain lead-bearing glass or terminations; engineers should request compliance documentation from the distributor before design-in for RoHS/REACH-regulated end products.
