EP910DM/883B - Altera Classic EPLD, 24 Macrocells, MIL-883B | Intel / Altera

Background: An EPLD (Erasable Programmable Logic Device) is a type of programmable logic IC that sits in the hierarchy between simple PLDs (PAL/GAL) and larger CPLDs/FPGAs. The classic Altera EPLD family uses UV-erasable or one-time-programmable CMOS cells to implement combinational and registered logic in a single non-volatile device, replacing dozens of 74-series TTL parts with one chip. EPLDs are non-volatile (retain configuration without a bootloader), deterministic in timing, and instantly reconfigurable, which is why they remain preferred for low-density, latency-critical applications and legacy MIL-grade designs.
Key features include 24 macrocells with flexible output polarity, 10 dedicated inputs, 12 bidirectional I/O pins, 4 sum-product terms per macrocell, and an in-system programmable architecture (on selected variants). The CMOS process yields typical standby current in the low milliamp range, and the ceramic DIP-24 package supports the MIL-STD-883B environmental and reliability screening that this /883B suffix designates.
The EP910DM/883B uses a programmable AND/OR array with output macrocells that can be configured as D, T, JK, or SR flip-flops. This allows designers to implement complex state machines, address decoding, and synchronous glue logic in a single device while preserving deterministic pin-to-pin propagation delays across operating conditions.
Typical applications include avionics data-bus controllers, military radar interface logic, naval communication backplanes, industrial-control state machines, and legacy VME/VXI interface adapters. The MIL-STD-883B screening specifically supports high-reliability environments where commercial-grade EPLDs would not meet vibration, thermal, or burn-in requirements.
When designing with this device, note that the EP910DM/883B requires a 5V VCC supply typical of the classic EPLD family and a programmer compatible with the Altera Classic architecture. Designers migrating to modern Intel/Altera devices should consider MAX II or MAX V CPLDs as the architectural successors.

Ứng dụng tiêu biểu
EP910DM/883B phù hợp cho 6 Áp dụngs: Military Avionics Bus Interface Logic, Radar Signal Processing Glue Logic, Naval Communication Backplane Controllers, Industrial Control State Machines, Legacy VME/VXI Interface Adapters, Aerospace Flight Control Redundancy Logic.
Military Avionics Bus Interface Logic
The EP910DM/883B implements MIL-STD-1553 or ARINC-429 bus controllers, address decoders, and handshake logic in avionics LRUs where the Altera Classic 24 macrocells provide ample headroom. Its MIL-STD-883B screening guarantees operation across -55C to +125C, vibration, and thermal-shock profiles demanded by DO-254 design assurance. Ceramic DIP-24 supports through-hole PCBs common in legacy avionics backplanes, and the part's 5 V CMOS interface matches older bus-driver ASICs without level shifters.

Radar Signal Processing Glue Logic
In phased-array radar front-ends the EP910DM/883B serves as deterministic glue logic between ADC/DAC converters and DSP processors, replacing dozens of 54-series TTL gates with one non-volatile device. The Altera Classic EPLD's nanosecond-class propagation delay preserves timing margins in beam-steering and pulse-compression paths. MIL-STD-883B screening is critical because radar electronics operate in high-vibration, high-temperature environments that disqualify commercial plastic EPLDs. Through-hole DIP-24 also simplifies field serviceability on deployed radar units.

Naval Communication Backplane Controllers
Navy communication systems on surface combatants and submarines depend on MIL-STD-883B-screened logic for secure data buses, crypto interfaces, and timing-distribution networks. The EP910DM/883B's 24 macrocells and 12 I/O pins support multi-channel protocol framing, while its non-volatile Altera Classic architecture eliminates boot time and configuration memory. Ceramic DIP-24 with hermetic packaging resists salt fog and humidity that would degrade commercial plastic parts, making EP910DM/883B a long-life-cycle choice for naval electronics.

Industrial Control State Machines
The EP910DM/883B replaces electromechanical relays and discrete logic in heavy-industrial PLCs, motor drives, and process-control systems where deterministic, non-volatile logic is mandatory. Its 24 macrocells comfortably hold complex state machines for sequential control of assembly lines or batch processes, and its MIL-STD-883B screening supports factory environments with high EMI and temperature swings. The ceramic DIP-24 footprint is mechanically rugged for vibration-prone factory floors.

Legacy VME/VXI Interface Adapters
Test-and-measurement racks using the VME and VXI backplane standards still rely on EPLDs for address decoding, interrupt steering, and bus arbitration. The EP910DM/883B's 24 macrocells and 12 I/O pins support full VME master/slave interfaces with deterministic timing. MIL-STD-883B screening ensures the adapter survives shipboard, airborne, and laboratory qualification testing, and the ceramic DIP-24 package aligns with the through-hole VME card form factor used in legacy instrumentation.

Aerospace Flight Control Redundancy Logic
Flight-control computers and actuator drivers use the EP910DM/883B to implement voting logic, watchdog timers, and discrete-output decoding in triplex or quad-redundant architectures. The Altera Classic EPLD's nanosecond propagation delay supports the deterministic response times required by DO-178C design assurance levels, while MIL-STD-883B screening ensures the part survives the altitude, vibration, and thermal profiles of commercial and military aircraft. Ceramic DIP-24 supports rugged chassis mounting.

Ghi chú thiết kế
Estimated: EP910DM/883B draws approximately 50-100 mA at 5 V depending on output switching frequency and output loading. Place 0.1 uF ceramic decoupling capacitors within 5 mm of each VCC pin and a single 10 uF tantalum bulk capacitor on the board's 5 V rail. CMOS logic families can produce significant supply transients during simultaneous output transitions; insufficient decoupling can cause VCC droop that mis-clocks internal registers.
The ceramic DIP-24 package (DM) is through-hole and benefits from socketed installation to allow UV erasure and re-programming of windowed variants. Keep input traces short and route clocks on inner layers with ground reference to minimize skew. For MIL-STD-883B programs, follow IPC-2222 section designs for through-hole ceramic packages and ensure pad finishes are SnPb (not lead-free) to maintain solder joint reliability in thermal-cycling environments.
Do not assume EP910DM/883B is RoHS-compliant - the /883B suffix targets military programs that frequently mandate SnPb lead-bearing terminations. Confirm with the manufacturer before specifying lead-free reflow profiles. Designers should also verify the variant ordering code carefully: EP910DM, EP910DC, EP910DI, EP910DM/883, and EP910DM/883B differ in package, screening, and speed grade, and the wrong suffix will cause qualification failures.
