EPM5032DI-20 - 32-Macrocell MAX 5000 EPLD, 62.5MHz, DIP-20 | Intel
MPN: EPM5032DI-20 ✗ Cuối đờiEPM5032DI-20 Tóm tắt
An EPLD (Erasable Programmable Logic Device) is a type of programmable logic IC that uses UV-erasable CMOS technology to implement combinational and registered logic in a single chip. The MAX 5000 family sits in the PLD hierarchy between classic 22V10-style PALs and the larger MAX 7000 / MAX 3000A CPLDs that followed it, providing higher density than SSI/MSI TTL packages while keeping the simple, deterministic PAL architecture familiar to legacy designers.
Key features include 32 macrocells with PAL-type architecture, 320 available product terms, 16 macrocell flip-flops, a global clock with programmable OE control per macrocell, and a single -20 speed grade suffix denoting 20 ns propagation delay. The 'DI' suffix indicates the ceramic DIP-20 industrial-temperature package, while 'I' denotes the commercial/industrial temperature range suitable for non-automotive designs.
Typical applications include glue-logic replacement of multiple 7400-series TTL/CMOS gates, bus-interface adapters, address decoding, state-machine controllers, and legacy industrial controllers where the MAX 5000 architecture is already qualified and a drop-in replacement with identical footprint is required.
When designing with the EPM5032DI-20, use the Altera MAX+PLUS II development tool or compatible third-party legacy programmers to generate JEDEC fuse files. Verify timing with the -20 speed-grade derating and ensure the ceramic DIP-20 socket footprint matches standard 0.300" through-hole tooling. This page synthesizes distributor pricing, drop-in alternatives from the same MAX 5000 family, and practical design notes not found in the original datasheet.

Ứng dụng tiêu biểu
EPM5032DI-20 phù hợp cho 6 Áp dụngs: TTL/CMOS Glue-Logic Replacement, Address Decoding and Bus Interface, State-Machine Controllers, Legacy Industrial Control Boards, Peripheral Chip-Select Generator, Educational and Prototyping Platforms.
TTL/CMOS Glue-Logic Replacement
The EPM5032DI-20 replaces dozens of 7400-series SSI/MSI TTL gates with a single 32-macrocell EPLD, freeing board space and reducing power consumption in legacy industrial designs. With 320 product terms and 16 macrocell flip-flops, it can absorb an entire address-decoder, bus-arbitration, or state-machine cluster that previously required 10-20 discrete packages. The 62.5 MHz fMAX and 20 ns pin-to-pin delay match the timing of standard 74LS and 74F TTL, so signal integrity is preserved.

Address Decoding and Bus Interface
The EPM5032DI-20's 32 macrocells and 320 product terms make it well-suited for address-decoding and bus-interface logic in 8-bit and 16-bit microprocessor systems. Each macrocell can implement a wide product-term sum (AND-OR), enabling complex address maps with chip-select outputs that previously required multiple 74LS138/139 decoders. The 7 dedicated inputs accept buffered address lines directly, while the 16 bidirectional I/O pins serve as peripheral chip-select outputs.
Được đề xuất
State-Machine Controllers
State-machine controllers with up to 16 registered states fit naturally into the EPM5032DI-20's 16 macrocell flip-flops and PAL-type AND-OR architecture. The deterministic per-macrocell delay and wide product-term fan-in simplify timing closure versus discrete 74LS/74F flip-flop packages. Designers can implement Moore or Mealy machines with combinational output logic using the same macrocell flip-flops, achieving 62.5 MHz operation at the -20 speed grade.
Được đề xuất
Legacy Industrial Control Boards
The EPM5032DI-20's ceramic DIP-20 industrial-temperature package and 20-year design heritage make it ideal for sustaining legacy industrial controllers that are still in service and where a board-level redesign is uneconomical. The windowed ceramic package supports UV erasure for field reprogramming during board rework, while the industrial temperature range tolerates factory-floor thermal cycling. Engineers maintaining 1990s-era PLCs, motor drives, and test fixtures rely on this exact part number.
Được đề xuất
Peripheral Chip-Select Generator
The EPM5032DI-20 generates multiple peripheral chip-select signals from a single address bus, replacing a stack of 74LS138/139 decoders with one 32-macrocell EPLD. Each macrocell's wide product-term sum (up to 16 product terms) accommodates complex address maps, while the 62.5 MHz fMAX keeps chip-select timing aligned with the host microprocessor's bus cycle. The 16 I/O pins comfortably drive 8-12 peripheral enables with two pins reserved for handshaking.
Được đề xuất
Educational and Prototyping Platforms
The EPM5032DI-20's UV-erasable windowed ceramic package and well-documented MAX+PLUS II toolchain make it a popular teaching aid in university digital-logic labs where students learn PAL-type architecture fundamentals. The 32-macrocell complexity is large enough to implement meaningful designs (UARTs, small CPUs, custom interfaces) yet small enough to fit a single lab session. Instructors value the predictable per-macrocell delay for teaching timing analysis.

Ghi chú thiết kế
The EPM5032DI-20 is a UV-erasable ceramic device, NOT one-time-programmable (OTP). If you cover the quartz window with opaque label, the part becomes difficult to reprogram; field engineers often forget this and lose the ability to update the JEDEC fuse file. For new designs where UV erasure is not required, prefer the plastic DIP-20 OTP variants (EPM5032DC-20 / EPM5032DC-25) for lower cost and easier handling.
Route all 7 dedicated inputs with short traces and place a 0.1 uF ceramic decoupling capacitor within 5 mm of the VCC pin (pin 20). The 16 bidirectional I/O pins each source/sink up to 8 mA (DC) per the MAX 5000 datasheet, so use wider traces (>= 0.3 mm) for any I/O pin driving LEDs or bus pull-ups. Add a bulk 10 uF tantalum capacitor on VCC for the simultaneous-switching current typical of PAL-type outputs.
The EPM5032DI-20 operates from a single 5 V supply and draws up to ~150 mA Icc when all 32 macrocells switch simultaneously at 62.5 MHz. Estimated: total dynamic power at 62.5 MHz with 50% toggle rate is roughly (150 mA x 5 V x 0.5) = 375 mW, dominated by the PIA charging/discharging. For battery-backed applications, gate the clock when the macrocells are idle to cut ICC by 80-90%.
Thông tin tuân thủ
Ceramic DIP-20 EPLD predates RoHS directives and is typically supplied as a legacy Altera/Intel part with non-compliant lead finish. RoHS/REACH status not stated in available data; obsolete-status parts are commonly exempted under RoHS Annex IV. Use plastic-DIP variants for new RoHS-compliant designs.
