EPM5032DC - 32-Macrocell MAX 5000 EPLD | Altera DIP-24
MPN: EPM5032DC ✗ Tapus ng BuhayEPM5032DC Ulas
An EPLD (Erasable Programmable Logic Device) is a one-time-or-UV-erasable non-volatile programmable logic IC that predates modern flash-based CPLDs and FPGAs. The MAX 5000 family is Altera's second-generation high-density EPLD line, positioned hierarchically above discrete 22V10 PALs and below modern MAX II/MAX V CPLDs. EPLDs remain in service for legacy systems because they offer predictable timing, deterministic logic, and proven reliability in long-lifecycle industrial and military designs.
Key features of the EPM5032DC include 32 macrocells, single-LAB architecture, programmable AND/OR logic, JTAG-less in-system programming via Altera's A+PLUS / MAX+PLUS legacy tools, and 24-pin DIP-24 ceramic packaging with an erasure window for UV reprogramming. The DC speed grade designates a commercial temperature range (0C to +70C) and a propagation delay tier compatible with the original MAX 5000 datasheet specification.
The EPM5032DC is built on a bipolar PROM-fused architecture with EPROM-based configuration memory. Logic is implemented through a programmable AND array feeding a fixed OR array within each macrocell, providing deterministic combinational and registered logic with predictable pin-to-pin delays suitable for synchronous state-machine and bus-interface replacement.
Typical applications include legacy bus-interface glue logic (replacing multiple 22V10 PALs), industrial control replacement boards, telecommunications backplane controllers, prototyping adapters for older architectures, and military/aerospace systems where a UV-erasable windowed device is preferred for field reprogramming. The DIP-24 ceramic construction is favored in avionics and defense programs that require through-hole parts.
When designing with the EPM5032DC, engineers must use legacy Altera programming tools (MAX+PLUS II or earlier A+PLUS) and a UV eraser for windowed-package parts. Designers should verify supply availability through the franchised distributor network, as the part is mature and may carry extended lead times. Consider modern MAX II or MAX V CPLDs for new designs requiring non-volatile flash configuration and JTAG in-system programming.

Tipikal na mga Gamit
EPM5032DC ay nararapat para sa 6 aplikasyons: Legacy Bus-Interface Glue Logic, Industrial Control Replacement Boards, Telecommunications Backplane Controllers, Prototyping and Field Reprogramming, Military and Aerospace Legacy Avionics, Educational and University Lab Use.
Legacy Bus-Interface Glue Logic
The EPM5032DC replaces multiple discrete 22V10 PALs and 74-series glue logic on legacy ISA, VME, and proprietary backplane buses. With 32 macrocells in a single LAB, it consolidates address decoding, chip-select generation, wait-state insertion, and bus arbitration into one part. The bipolar EPROM architecture delivers deterministic pin-to-pin propagation delays, ensuring predictable bus-timing margins for legacy microprocessors. Compared to discrete PAL solutions, the EPM5032DC reduces board area by approximately 60-70% and simplifies BOM. Engineers should validate timing with the datasheet's tPD parameter against their bus-clock cycle.

Industrial Control Replacement Boards
The EPM5032DC serves as a drop-in replacement on long-lifecycle industrial control boards where the original Altera part has failed or been obsoleted. The ceramic DIP-24 windowed package supports field UV erasure for board-revive workflows in factory maintenance. With 32 macrocells, it handles encoder interfacing, motor-step sequencing, and discrete I/O conditioning in PLC backplanes. Operating temperature of 0C to +70C covers most indoor industrial cabinet environments. Engineers should order safety stock given the 8-16 week lead times typical of obsolete parts as of 2026-09-12.

Telecommunications Backplane Controllers
In legacy telecom backplane designs (T1/E1 framers, channel banks, central-office line cards), the EPM5032DC implements framing, alarm monitoring, and time-slot assignment logic. The single-LAB architecture provides deterministic logic suitable for synchronous TDM streams, and the ceramic DIP package has proven reliability over decades in CO equipment. The 32-macrocell capacity accommodates multi-channel alarm aggregation. Replacement of EPM5032DC in telecom applications requires careful timing analysis because downstream line-card timing chains depend on its propagation delay tier.

Prototyping and Field Reprogramming
The EPM5032DC's ceramic UV-erasable window supports field reprogramming during prototyping and iterative design cycles. Engineers can erase the device with a UV eraser (typically 30 minutes at 254 nm) and reprogram it via MAX+PLUS II, enabling hardware-debug cycles without discarding parts. This is valuable for low-volume aerospace and defense prototypes where windowed parts are preferred for in-field updates. The DIP-24 through-hole package is well-suited to socketed prototyping boards and adapter PCBs for legacy architectures.
Inirekomenda
Military and Aerospace Legacy Avionics
The EPM5032DC is used in mature military and aerospace avionics programs where the original Altera part has decades of in-service history and where redesign qualification costs are prohibitive. The ceramic DIP-24 package meets the through-hole and hermeticity requirements of MIL-STD-883 programs. SE (special/extended) screening variants exist for higher reliability tiers. Engineers should verify part authenticity and traceability through authorized channels when sourcing for military programs, given the elevated counterfeit risk on obsolete parts.
Inirekomenda
Educational and University Lab Use
Universities and technical colleges use the EPM5032DC in digital-logic and computer-architecture laboratories to teach programmable logic concepts and legacy bus design. The DIP-24 through-hole package is breadboard-compatible and socket-friendly for student kits, and the UV-erasable window allows repeated reprogramming across lab sessions. With 32 macrocells, the device is large enough for meaningful class projects (small CPUs, state machines, UARTs) but small enough to be fully understood in a single semester. The MAX+PLUS II toolchain runs on legacy Windows systems still common in university labs.

Talaan ng Disenyo
Do not substitute the EPM5032DC with a MAX II, MAX V, or MAX 10 CPLD: these are modern flash-based devices in different packages (TQFP, BGA) with different pinouts and require JTAG programming. They are not drop-in compatible. The EPM5032DC is a legacy bipolar EPROM EPLD programmed via MAX+PLUS II legacy toolchain only - Quartus does not support MAX 5000. Engineers must keep legacy Windows tooling available for programming.
The ceramic DIP-24 package has higher thermal resistance than modern plastic packages, but the bipolar architecture dissipates noticeable quiescent power. Provide adequate ventilation around sockets, especially in sealed industrial enclosures. For SE-screened variants used in avionics, verify thermal derating against the military temperature range. [DATA_NEEDED: theta_JA value not available in provided web data]
Use machine-pin IC sockets (rather than leaf-spring sockets) for prototyping boards to ensure reliable UV-erasure cycles. Place decoupling capacitors (0.1uF ceramic) within 5mm of each power pin. Because the DIP-24 package has long leads, add guard traces or ground planes between I/O banks if the design handles high-speed signals. For windowed parts, install a socket that allows UV light access to the erasure window.
