EP1810GM/883B 概要
An EPLD (Erasable Programmable Logic Device) is a type of programmable logic IC that preceded modern CPLDs and FPGAs. EPLDs use EPROM/EEPROM cells to define AND/OR macrocell logic that implements Boolean sum-of-products expressions. They occupy the middle ground between PALs (too few gates) and FPGAs (more flexible but slower and more power-hungry in this era), offering deterministic 10 ns tPD with predictable timing — ideal for address decoding, bus interface logic, and state-machine replacement in legacy systems.
Key features of the EP1810GM/883B include approximately 900 usable gates, 48 macrocells, and 6 dedicated input pins plus 48 I/O pins routed through the classic interconnect. The 181-pin PGA package supports high signal integrity for the 48 bidirectional I/Os and is screened to MIL-STD-883 Class B for operation across the military -55C to +125C temperature range. The 0.8 micron CMOS EPROM process yields low standby current and 5V-tolerant inputs on a single 5V supply.
Architecturally, the EP1810 uses a programmable AND array feeding fixed OR terms within each macrocell, with each macrocell offering a flip-flop for registered outputs. The classic interconnect delivers 10 ns pin-to-pin with no skew variation across the die, which is a key differentiator versus early FPGAs. The device is in-system programmable via a JTAG-like serial interface (compatible with Altera's MAX+plus II legacy flow) and supports 100% AC testing per MIL-STD-883.
Typical applications include military avionics bus interfaces (MIL-STD-1553 glue logic), legacy radar system timing, industrial CNC controller decode logic, replacement of multiple TTL/CMOS PALs in defense electronics, and high-reliability address decoding for VME and VXI backplanes. The ceramic PGA package is preferred in environments with hermetic-seal requirements.
When designing with this part, ensure your programmer supports the Altera Classic device family (MAX+plus II or a compatible vintage toolchain). The 181-pin PGA footprint requires a socketed through-hole PCB layout, and obsolete-toolchain support must be maintained across the product lifecycle.

主な用途
EP1810GM/883B の用途: 6 件s: Military Avionics Bus Interface Glue Logic, Legacy Radar System Timing and Decode, VME/VXI Backplane Address Decoding, TTL/CMOS PAL Replacement in Defense Electronics, Industrial CNC Controller Decode Logic, Spacecraft Avionics Subsystems.
Military Avionics Bus Interface Glue Logic
The EP1810GM/883B is ideally suited for military avionics bus interface glue logic where MIL-STD-883B screening is mandated. With 48 macrocells and 10 ns pin-to-pin delay, it can implement MIL-STD-1553 interface state machines, ARINC 429 decode/encode logic, and discrete-to-bus signal conditioning glue logic. The deterministic 10 ns timing — independent of internal routing — eliminates skew issues that plague contemporary FPGAs in safety-critical flight systems. The ceramic PGA-181 package supports hermetic sealing required for unpressurized avionics bays operating across -55C to +125C.
おすすめ
Legacy Radar System Timing and Decode
The EP1810GM/883B serves as decode and timing glue logic in legacy radar systems where modern FPGA firmware validation cycles are impractical. The 100 MHz counter frequency enables radar timing chains and range-gate pulse generation, while 48 macrocells implement decoder trees for radar control bus addresses. The deterministic 10 ns propagation delay — same regardless of macrocell placement — simplifies worst-case timing analysis in radar timing budgets. MIL-STD-883B screening ensures reliable operation in the temperature and vibration environment of land-based and shipboard radar installations.
おすすめ
VME/VXI Backplane Address Decoding
The EP1810GM/883B is well suited for VME and VXI backplane address-decoding applications in military and industrial test equipment. With 48 I/O pins it can decode multiple VME address lines plus interrupt acknowledge, bus grant, and board-select signals. The 10 ns tPD ensures that board-select outputs settle before the VME cycle completes, avoiding bus contention. The single 5V supply matches VME bus power rails directly, and the ceramic PGA package withstands the mechanical and thermal environment of VXI chassis.
おすすめ
TTL/CMOS PAL Replacement in Defense Electronics
The EP1810GM/883B consolidates multiple discrete TTL and CMOS PAL/GAL devices in defense electronics where board real estate and reliability matter. A typical EP1810GM/883B design replaces 4-8 standard 22V10 PALs with a single 181-pin PGA, reducing component count by 70-80 percent. This consolidation improves MTBF significantly, an important metric for unmanned defense platforms with multi-decade operational lifetimes. MIL-STD-883B Class B screening with full Group A/B/C/D testing supports the long deployment cycles of military hardware.
おすすめ
Industrial CNC Controller Decode Logic
The EP1810GM/883B provides reliable decode and sequencing logic in industrial CNC controllers where 24/7 factory operation demands high-MTBF components. The 48 macrocells implement axis-enable decode, tool-changer sequencing, and safety-interlock logic with deterministic 10 ns timing. The -55C to +125C operating range covers harsh factory environments including unheated enclosures and machine-tool thermal loads. Although the part is obsolete, long-term factory automation customers maintain installed bases that still rely on this device.
おすすめ
Spacecraft Avionics Subsystems
The EP1810GM/883B is used in long-life spacecraft avionics subsystems where radiation-tolerant commercial parts with extensive heritage are preferred over newer rad-hard FPGAs. The Classic EPLD's simple CMOS EPROM architecture offers intrinsic radiation tolerance superior to SRAM-based FPGAs of the same era, and the MIL-STD-883B screening plus established flight heritage qualify it for low-Earth-orbit and geosynchronous satellite platforms. The 10 ns tPD supports spacecraft command/telemetry decoder timing budgets, and the ceramic PGA withstands the thermal-vacuum environment of orbital operation.

設計ノート
The EP1810GM/883B requires the legacy Altera MAX+plus II toolchain (v9.23 baseline or later 10.x releases) — modern Intel Quartus Prime does not support Classic EPLDs. Maintain a licensed copy of MAX+plus II plus an Altera LP6, ByteBlasterMV, or compatible third-party programmer. EPROM cells are UV-erasable, so any rework on the ceramic PGA package requires a windowed sample and an EPROM eraser — production units are typically one-time-programmable.
Estimated: at 5V supply, 100 MHz operation, with all 48 macrocells toggling, the EP1810GM/883B draws approximately 200-300 mA active ICC — about 1-1.5 W dissipation. The ceramic PGA-181 package with adequate socket airflow or chassis conduction cooling handles this within the -55C to +125C military range, but verify theta_JA from the EP1810 datasheet for your specific socket and PCB layout before finalizing thermal budgets.
The 181-pin PGA requires a through-hole socket on the PCB — typically a machined-pin PGA socket (e.g., 3M Textool or equivalent). Allocate at least 1.5 square inches of PCB area for the socket footprint plus 0.2 inches clearance on all sides. Decoupling: place one 0.1 uF ceramic per VCC pin group plus a 10 uF tantalum bulk capacitor near the package. Keep TTL/CMOS input traces short to avoid 10 ns timing margin erosion.
The EP1810GM/883B is obsolete. For new military designs, consider last-time-buy planning or migrate to a current-generation CPLD such as Intel MAX II EPM240 / EPM570 or Microsemi (Microchip) ProASIC3 — all of which require PCB redesign and Quartus Prime / Libero toolchain porting. For sustainment of fielded systems, qualify multiple broker sources with full MIL-STD-883B Group A/B/C/D test records and Certificates of Conformance to mitigate counterfeit risk.
コンプライアンス情報
MIL-STD-883 Class B screening per /883B suffix. Ceramic PGA package is not RoHS-compliant due to lead-bearing ceramic and pin finishes typical of 1990s military packaging. REACH compliance applies to SVHC declarations per current distributor documentation. Not AEC-Q100 qualified (automotive IC standard not applicable to military-grade EPLDs).
