EP1810LC-30 Übersicht
Classic EPLDs occupy a specific niche in the programmable logic taxonomy: they sit between discrete TTL/CMOS glue logic (PAL/GAL) and modern SRAM-based FPGAs. An EPLD is a one-time- or UV-erasable PLD that uses sum-of-products macrocell architecture to implement combinational and registered logic. Compared to simple 22V10-style PALs, a Classic EPLD offers higher macrocell density, predictable timing, and lower power consumption than equivalent discrete SSI/MSI implementations. Compared to FPGAs, EPLDs provide instant-on behavior (no configuration PROM required), deterministic fixed timing, and very low standby current, which is why they remained popular for control-plane glue logic, bus interfacing, and address decoding well into the 2000s.
The EP1810LC-30 supports typical tPD (propagation delay) of 30 ns at 5 V operation, four dedicated input pins, a global clock network, and asynchronous clear/preset on each macrocell. Programmable I/O architecture allows each pin to be configured as input, output, or bidirectional with output enable control. The device is in-system programmable through a JTAG-compatible interface and provides security-bit support to protect designs from readback.
Typical applications include address decoding for microprocessor/microcontroller systems, bus interfacing and arbitration logic, state-machine and sequencer replacement for discrete 74LS/74HC logic, peripheral glue logic in legacy industrial controllers, and replacement of multiple discrete PLD/PAL devices with a single integrated part. The 30 ns speed grade is well-matched to 8-bit and 16-bit bus interfaces (e.g., 8086, 68000) where address decode must complete within one clock cycle.
When designing with the EP1810LC-30, account for the ceramic package thermal mass (suitable for harsh environments) and the 30 ns propagation delay when computing system timing margins. For new designs, modern CPLDs from Intel (MAX series) or Lattice (ispMACH) provide higher density and lower power in smaller packages, but the EP1810LC-30 remains in demand as a drop-in replacement for legacy boards.

Typische Anwendungen
EP1810LC-30 ist geeignet für 7 Anwendungs: Microprocessor Address Decoding, Bus Arbitration and Interface Logic, Legacy Industrial Controller Glue Logic, State Machine and Sequencer Replacement, Peripheral Chip Select Generation, Military and Aerospace Legacy Systems, Test Equipment and Instrumentation.
Microprocessor Address Decoding
The EP1810LC-30 is well-suited for microprocessor address decoding in 8-bit and 16-bit systems such as the 8086, 68000, and Z80. Its 48 macrocells easily handle chip-select logic for memory banks, peripheral I/O, and DMA controllers, replacing multiple 74LS138/139 decoders with a single integrated device. The 30 ns tPD fits within one clock cycle of legacy 5-10 MHz bus systems, ensuring valid chip selects before the next bus cycle. Programmable I/O polarity and product-term sharing simplify address-map changes during development.
Empfohlen
Bus Arbitration and Interface Logic
In multi-master systems (VME, ISA, PC/104, Multibus), the EP1810LC-30 implements bus arbitration, request/grant sequencing, and wait-state generation in a single device. Its deterministic 30 ns timing simplifies worst-case latency analysis, and the registered macrocells provide clean state-machine implementation for bus-protocol handshakes. The CMOS low-power design minimizes heat dissipation in densely populated backplane cards where multiple EPLDs operate simultaneously.
Empfohlen
Legacy Industrial Controller Glue Logic
Industrial controllers, PLCs, and CNC machines built in the 1990s-2000s use the EP1810LC-30 to consolidate discrete 74LS/74HC glue logic into a single reprogrammable part. Field-service replacement requires the exact part number; the EP1810LC-30 fits existing board layouts without redesign. The CMOS technology delivers low standby current suitable for battery-backed control systems, and the ceramic JLCC-68 package withstands industrial temperature and vibration environments.
Empfohlen
State Machine and Sequencer Replacement
The EP1810LC-30 is ideal for replacing discrete 74LS/74HC state-machine implementations - one EPLD can replace 5-10 small-scale integration packages, reducing board area and improving reliability. Each macrocell provides a flip-flop with asynchronous clear/preset, perfect for Moore or Mealy state machines. Design entry via ABEL, CUPL, or Altera's MAX+PLUS II allows quick iteration, and the same JEDEC file can be programmed into any speed-grade variant.
Empfohlen
Peripheral Chip Select Generation
The EP1810LC-30 generates chip-select signals for memory and peripheral devices in embedded systems, with each macrocell implementing one product term in the address-decode equation. The 30 ns delay fits within standard peripheral-access timing for UARTs, timers, parallel I/O chips, and SRAM/ROM. Programmable output polarity (active-high or active-low) accommodates any chip-select convention without external inverters, simplifying PCB layout.
Empfohlen
Military and Aerospace Legacy Systems
The ceramic JLCC-68 package and CMOS low-power design of the EP1810LC-30 make it suitable for military and aerospace legacy systems where thermal cycling, vibration, and radiation tolerance matter. While not formally MIL-STD-883 qualified in all speed grades, the ceramic package itself supports the temperature and mechanical requirements. For modern military designs, the EP1810GM/883B and EP1810GM883 screened variants provide formal MIL-STD-883 processing.
Empfohlen
Test Equipment and Instrumentation
Bench-top test equipment and ATE systems from the late 1990s and 2000s use the EP1810LC-30 to implement custom timing generators, pulse shapers, and pattern generators. Its reprogrammability allows engineers to iterate on test patterns without board respins, and the 30 ns timing suits most general-purpose instrumentation clock rates. When production-test timing margins are tight, designers can substitute the EP1810LC-25 or EP1810LC-20 in the same socket.

Wichtigste Unterscheidungsmerkmale
- Pin-compatible speed-grade flexibility within same family (vs. EP1810LC-25)
- Low-power CMOS technology (LC suffix) (vs. EP1810GC-35)
- Ceramic JLCC-68 package durability (vs. Plastic PLCC-68 EPLDs)
Designhinweise
Estimated: The EP1810LC-30 supports 48 macrocells but only a subset of I/O pins are usable depending on the chosen pinout. When designing with ABEL, CUPL, or MAX+PLUS II, reserve at least 4 macrocells for output enables and global control signals (input clock, OE, clear). Exceeding the macrocell budget is the most common design failure for first-time EPLD users; verify the fitted design report before committing to programming.
The ceramic JLCC-68 package provides excellent thermal performance (theta_JA approximately 30-40 C/W) suitable for industrial and military temperature ranges. However, unlike plastic packages, the ceramic body does not flex; mechanical stress on PCB through-hole or socket pins can crack solder joints. Use pin sockets (e.g., machined-pin IC sockets) for prototype builds and conformal coating for high-vibration deployments.
Place decoupling capacitors (0.1 uF ceramic + 10 uF tantalum or electrolytic) within 5 mm of each VCC/GND pin pair. The EP1810LC-30 has multiple VCC and GND pins; the datasheet pinout specifies which pins must be connected. Missing or improper decoupling causes intermittent logic errors and reset glitches, especially in noisy industrial environments.
Estimated: At 30 ns tPD, the EP1810LC-30 is well-suited for bus frequencies up to approximately 16 MHz. For higher-speed buses, upgrade to the EP1810LC-25 (25 ns) or EP1810LC-20 (20 ns) - these are pin-compatible drop-in alternatives. Long PCB traces (>50 mm) on clock or output-enable lines may require series termination (33-68 ohm) to prevent reflections.
Compliance-Informationen
Compliance status not stated in the available web data; the legacy ceramic JLCC package typically contains lead-based solder (SnPb) and is not RoHS compliant. For RoHS-compliant alternatives in the same family, refer to plastic PLCC variants. The part is obsolete and not recommended for new commercial designs requiring modern environmental compliance.
