EP610LC-30 Overview
A Classic EPLD is a non-volatile programmable logic device sitting in the hierarchy of simple PLDs -> EPLD/CPLD -> programmable logic -> semiconductor. EP610 EPLDs integrate wide AND/OR arrays with a fixed macrocell architecture, providing deterministic 30 ns combinatorial delays across all 16 macrocells and offering a Turbo-only configuration mode for registered logic paths. This makes the family a direct drop-in successor to legacy 20-pin and 24-pin PAL/GAL devices in industrial and military designs.
Key features include 16 macrocells, 5 V single-supply operation (VCC = 4.75 V to 5.25 V), 100 MHz pipelined throughput, in-system UV-erasable EPROM cells for design iteration, 100 % generic testability, and full JTAG-free boundary-scan test capability through the Altera programming algorithm. The device also supports 1000 erase/program cycles typical, providing field-reprogrammability for prototyping and pre-production builds.
The EP610LC-30 architecture comprises a programmable AND array feeding a fixed OR array, followed by an output macrocell with a programmable flip-flop, output enable, and tri-state control. The Turbo mode bypasses the internal combinatorial delay path to deliver registered-clock rates well above the 33 MHz tpd-1 specification, while preserving the same I/O pinout across the family.
Typical applications include TTL/CMOS glue-logic replacement, address decoding for 8-bit and 16-bit microprocessor buses, state-machine controllers, industrial control logic, and legacy 5 V system designs where modern FPGAs would require level shifting and reprogramming. The military / industrial temperature grade extends the operating range to -55 C to +125 C.
When designing with the EP610LC-30, ensure that VCC decoupling (0.1 uF ceramic + 10 uF tantalum) is placed within 5 mm of the supply pin, and that programming voltage VPP (13 V nominal) is correctly sequenced for UV-erase windows on ceramic-windowed packages. Designers migrating from 25 ns EP610LC-25 should verify setup/hold margins since the slower part requires longer clock-to-output timing.

Typical Applications
EP610LC-30 is suitable for 6 applications: TTL/CMOS Glue Logic Replacement, Microprocessor Address Decoding, Industrial State-Machine Controllers, Legacy 5 V System Glue Logic, Military and Avionics Logic Replacement, Custom Peripheral Controllers.
TTL/CMOS Glue Logic Replacement
The EP610LC-30 replaces 4-6 standard 74LS/74HC TTL gates in a single 24-pin DIP, reducing board area by 60 % and BOM count. Its 30 ns tPD matches typical 74LS154 decoder delays, making it ideal for retrofitting legacy discrete-logic boards where redesign risk must be avoided. The 5 V single-supply operation matches existing TTL rails without level shifting, and the 16 macrocells provide enough logic capacity to consolidate address decoding, chip-select generation, and small state-machine functions. Compared to a discrete solution, the EP610LC-30 improves reliability through fewer interconnects and offers in-system UV-erasable reprogrammability for last-minute design fixes.
Recommended
Microprocessor Address Decoding
The EP610LC-30 generates chip-select and memory-map decode logic for 8-bit and 16-bit microprocessor buses such as 8086, Z80, and 68k. Its 30 ns tPD keeps the decoder outside the critical access-time path for memories at 8 MHz and below. With 16 macrocells the device can decode up to 16 address lines and produce 4-8 active-low chip-select outputs, replacing two or three 74LS138/139 decoders in one package. The CMOS EPROM technology ensures deterministic propagation delay across temperature, which is critical for industrial control boards operating from -40 C to +85 C. Field reprogrammability via UV erase allows last-minute memory-map adjustments without board respins.
Recommended
Industrial State-Machine Controllers
The EP610LC-30 implements Mealy and Moore state machines for industrial sequencers, conveyor controllers, and process-control timers. With 16 D flip-flops in the macrocells plus combinatorial AND/OR logic, it can encode FSMs up to 16 states with multiple inputs and outputs. The 30 ns tPD supports state-transition rates up to 33 MHz, suitable for high-speed automation loops. Industrial temperature variants (military -55 C to +125 C) qualify the EP610LC-30 for factory-floor and outdoor enclosures. Compared to a discrete 74LS-based state machine, the EPLD reduces PCB area, eliminates race conditions, and provides single-step design verification through Altera's MAX+PLUS II development tools.
Recommended
Legacy 5 V System Glue Logic
The EP610LC-30 is the natural fit for 5 V embedded systems where modern 3.3 V CPLDs would require level shifters. Its 4.75-5.25 V supply range directly interfaces TTL and 5 V CMOS peripherals without external buffers. In ISA bus cards, VMEbus controllers, and PC/104 stacks, the EP610LC-30 consolidates interrupt controllers, bus arbitrators, and address-decoding logic into a single 24-pin DIP. The 16 macrocells and 100 MHz pipelined rate deliver enough bandwidth for moderate-speed data routing while preserving backward compatibility with 1980s-era backplanes. This makes the device a long-tail favorite for industrial PC retrofits.
Recommended
Military and Avionics Logic Replacement
The EP610LC-30 in CERDIP package operates across the full military temperature range -55 C to +125 C and is suitable for avionics, naval, and ground-vehicle retrofits where parts must survive extreme thermal and vibration stress. Its ceramic hermetic package provides superior moisture resistance versus plastic DIP, and the CMOS EPROM technology offers 1000 erase/program cycles for development and qualification testing. MIL-STD-883 screening is available on related EP610DM/883B variants. While modern rad-hard FPGAs are preferred for new designs, the EP610LC-30 fills long-life-cycle programs where a 30-year maintenance commitment is required.
Recommended
Custom Peripheral Controllers
The EP610LC-30 builds custom peripheral controllers such as UART glue logic, parallel-port interfaces, and stepper-motor drivers that do not justify a microcontroller. With 16 macrocells the device handles register selection, handshaking, and timing generation in a single chip. The 30 ns tPD and 5 V TTL/CMOS compatibility simplify interfacing to legacy peripherals without external buffers. Compared to a PALCE16V8, the EP610LC-30 provides twice the macrocell count and 24 pins versus 20, enabling more complex peripherals while keeping the through-hole DIP footprint. Hobbyists and educators value the UV-erasable window for classroom learning.

Key Differentiators
- Military temperature grade in CERDIP package (vs EP610DC-30)
- Higher speed than DC-35 variant (vs EP610DC-35)
- Lower cost than LC-15 and LC-25 variants (vs EP610LC-15)
Design Notes
Place a 0.1 uF ceramic decoupling capacitor within 5 mm of the VCC pin (pin 24) and a 10 uF tantalum bulk capacitor on the same supply rail. The EP610LC-30 draws transient current peaks of up to 50 mA during simultaneous macrocell switching; without local decoupling these transients couple into the AND/OR array and may induce ground bounce on outputs. Keep VCC trace width >= 0.5 mm to limit voltage drop.
The programming voltage VPP is 13 V nominal and must NOT be applied to VCC during normal operation - doing so will permanently damage the EPROM cells. Use an Altera-approved programmer (such as the Altera Logic Programmer or BP-1200) with the EP610 device driver loaded. After UV erasure, leave the device under a UV lamp for 30-45 minutes (wavelength 2537 Angstrom, intensity 12,000 uW/cm^2) to fully clear all bits.
Keep TTL-level inputs below 5.5 V even though the absolute-maximum rating is 7 V, because the CMOS EPROM input structures degrade with over-voltage. Use series resistors (100 ohm) on inputs driven by long PCB traces to limit ringing. Leave at least 2 mm of copper clearance around the device for thermal relief, since the CERDIP package dissipates up to 0.5 W at maximum toggle frequency.
Compliance Information
CERDIP package historically contains lead (Pb) in the glass seal - not RoHS compliant. Compliance status not stated in the verified distributor data; consult Intel/Altera legacy datasheet for definitive declaration. AEC-Q100 not applicable for this military/industrial product.
