EP610ILC-10 Overview
An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device that combines the integration density of early PLDs with erasable EPROM-style configuration memory; in the broader taxonomy EPLD -> PLD -> programmable logic -> digital IC, the EP610 sits at the low-density end typically used to replace discrete TTL/CMOS glue logic, state machines, address decoders, and bus-interface functions. The Classic family provides pin-to-pin delays of 10-25 ns and supports counter frequencies up to 100 MHz, making it suitable for synchronous control logic in industrial and embedded systems.
Key features of the EP610ILC-10 include 160 product terms, 4 dedicated inputs, 16 I/O pins, and a 5 V single-supply operation; the -10 speed grade delivers 10 ns tPD and 100 MHz fCNT, allowing the device to be clocked at full speed without metastability issues typical of slower PALs. The macrocell architecture supports both registered and combinatorial outputs with feedback, enabling efficient state-machine implementation. The PLCC-28 package uses J-leads suitable for socketed programming and field replacement, which is important for legacy and MIL-spec applications.
Typical applications include address decoding in 8086/68000 microprocessor systems, glue logic in VMEbus/ISA backplanes, state machines in industrial controllers, and bus arbitration logic in legacy embedded systems. The 5 V supply and TTL-compatible I/O make the EP610 directly compatible with bipolar and CMOS 5 V logic families including 74LS, 74HC, and 74F series.
When designing with the EP610ILC-10, ensure that input rise/fall times remain below the datasheet limit to avoid AC noise issues, and provide proper decoupling with 0.1 uF capacitors on each VCC pin. Because the EP610 is a legacy part with limited current production, engineers should verify lifecycle status with the distributor before committing to new designs and consider pin-compatible successors such as the EP610ILC-12 or EP910 for higher gate counts.

Typical Applications
EP610ILC-10 is suitable for 6 applications: Microprocessor Address Decoding, VMEbus / ISA Bus Glue Logic, Industrial State Machine Controller, Legacy Embedded System Replacement, TTL/CMOS Glue Logic Consolidation, Aerospace/MIL-STD Field-Replaceable Logic.
Microprocessor Address Decoding
The EP610ILC-10's 16 macrocells and 4 dedicated inputs make it an efficient address decoder for 8086, 68000, and similar 5 V microprocessor systems. Its 10 ns tPD is fast enough to decode a 16- or 20-bit address bus in a single-pass, generating chip-select signals for memory and peripheral devices without wait states. The 100 MHz fCNT rating also lets the device handle synchronous control logic alongside the CPU clock. Compared to discrete 74LS/74F TTL decoder cascades, the EP610ILC-10 replaces 4-6 decoder packages with a single PLCC-28 part, simplifying PCB layout and improving reliability.
Recommended
VMEbus / ISA Bus Glue Logic
The EP610ILC-10 integrates multiple bus-interface functions - data buffers, address latching, interrupt acknowledge, and bus arbitration - into one 5 V PLD in a 28-pin PLCC package. The 16 I/O pins are sufficient for 8- or 16-bit data bus arbitration plus 4 control signals, while the 4 dedicated inputs accept bus grant/acknowledge and system clock. The 10 ns tPD matches VMEbus and ISA timing budgets, and the TTL-level I/O is directly compatible with bus transceivers like the 74LS245 or 74F245. Engineers typically use one EP610ILC-10 per bus slot to replace 2-4 discrete decoder/logic packages.
Recommended
Industrial State Machine Controller
The EP610ILC-10 is well-suited for synchronous state machines in PLCs, motor controllers, and process-control equipment, with 16 macrocells capable of encoding 8-12 states with combinational outputs. The 100 MHz fCNT rating supports high-speed sequencing of discrete I/O events, while the registered output mode lets each macrocell implement a D flip-flop for state-register functions. Because the EP610 is a non-volatile PLD, the state-machine definition is retained across power cycles without boot-time configuration, an advantage over SRAM-based FPGAs in safety-critical industrial applications.
Recommended
Legacy Embedded System Replacement
The EP610ILC-10 is widely used to repair and maintain legacy VMEbus, Multibus, and STD-bus systems installed in industrial machinery and aerospace test equipment from the 1980s and 1990s. Its PLCC-28 package can be socketed for field replacement without desoldering, simplifying maintenance on equipment where the original PLDs have failed or were damaged by handling. Distributors such as Jotrin and Nantian stock limited quantities specifically for this MRO (maintenance-repair-overhaul) market. The 5 V supply and TTL I/O ensure direct compatibility with original 5 V logic in the host system.
Recommended
TTL/CMOS Glue Logic Consolidation
Designers use the EP610ILC-10 to consolidate 4-10 discrete 74LS, 74HC, or 74F series logic packages - gates, multiplexers, latches, and small decoders - into one PLD. Each macrocell replaces a small cluster of discrete gates, and the 160 product terms provide enough logic capacity for typical glue-logic designs. The 5 V TTL-compatible I/O lets the EP610ILC-10 drop into existing TTL-based designs without level shifting, and the 10 ns tPD matches 74F performance while reducing PCB area and improving noise margin.
Recommended
Aerospace/MIL-STD Field-Replaceable Logic
In aerospace and military test equipment, the EP610ILC-10 serves as a field-replaceable programmable logic part on legacy 5 V systems, with PLCC-28 sockets enabling rapid swap-out during line maintenance. The same-family EP610DM/883B and EP610DI variants provide MIL-STD-883B screening for harsher environments, but the EP610ILC-10 is acceptable for industrial-grade avionics subsystems. The non-volatile UV-erasable configuration memory allows one-time programming and long-term retention, an advantage for mission-critical firmware-logic paths.

Key Differentiators
- Fastest speed grade in the EP610 family (vs EP610ILC-12)
- Industrial temperature range vs commercial-only EP610DC-10 (vs EP610DC-10)
- Lower timing margin than slower EP610DC grades (vs EP610DC-15)
- Higher-density migration path to EP910 family (vs EP910 (24 macrocells, PLCC-44))
Design Notes
The EP610ILC-10 operates from a single 5 V supply on pin 24, with GND on pin 12. Place a 0.1 uF ceramic decoupling capacitor as close as possible to the VCC pin, plus a bulk 1-10 uF tantalum or electrolytic cap on the same power rail. The PLCC-28 package distributes power through the corner pins, so symmetric placement of bypass capacitors on both VCC/GND corners reduces switching noise. Because the part draws CMOS-level quiescent current (typically <100 mA), thermal management is not a concern even at full 100 MHz operation.
Keep input rise/fall times below the datasheet limit (typically 250 ns for 5 V CMOS inputs) to avoid AC noise-induced oscillation on unused inputs. Unused I/O macrocell pins should be configured as outputs driving low or left open per datasheet recommendations. For high-speed 100 MHz designs, maintain controlled-impedance traces on the clock input (pin 26) and route critical signals on inner PCB layers with continuous ground reference. Place a 33 ohm series termination on clock traces longer than 50 mm to dampen ringing.
Use a PLCC-28 socket (e.g., 3M 8430 series) for prototype and field-replaceable applications; for production, the PLCC-28 can be surface-mount soldered with standard J-lead profile (peak 235-245 C, 60-90 s above 183 C). Maintain at least 0.5 mm clearance between PLCC J-leads and adjacent components; the package footprint requires 4 solder pads at the corners for mechanical stability. Avoid placing the EP610ILC-10 near heat sources or analog-sensitive circuits, as the 100 MHz switching can couple noise into nearby traces if not properly ground-isolated.
Do not exceed the maximum input voltage of 7 V absolute maximum, or the latchup threshold of the CMOS EPROM cells. Verify that the 5 V supply is well-regulated (within +/-5%) before programming the device, as undervoltage during programming can leave cells partially programmed. When using the EP610ILC-10 as a replacement for TTL logic, ensure the output drive current (typically 4-8 mA per pin) is sufficient for the load - use a buffer like the 74LS244 if driving high fanout. Finally, the EP610ILC-10 is UV-erasable, so windowed ceramic packages can be reprogrammed but plastic PLCC packages are OTP only.
Compliance Information
Compliance data not in verified sources; EP610 family is a legacy Altera (now Intel FPGA) part with limited compliance documentation. Not AEC-Q100 qualified (industrial/aerospace grade is via -DM/883B and -DI variants). Verify RoHS/lead-free status with distributor per specific date code before use in RoHS-compliant designs.
