EP610SC-20 Visão geral
An EPLD (Erasable Programmable Logic Device) is a non-volatile reprogrammable logic device that sits in the programmable logic hierarchy between simple PAL/GAL devices and modern CPLDs/FPGAs. Classic EPLDs use EPROM cells to store the configuration, providing true non-volatile instant-on behavior without external boot memory. The EP610 family belongs to Altera's first-generation classic architecture, later succeeded by MAX-series CPLDs, and is often specified for long-lifecycle industrial, telecom, and aerospace systems where modern FPGAs are unacceptable for legacy reasons or where instant-on logic glue is required.
Key features of the EP610SC-20 include 16 macrocells (24-pin logic capacity), 22 ns tPD combinational delay enabling 100 MHz pipelined operation, 5V CMOS I/O, and 300 gate equivalent density. The 24-pin SOIC package offers easy through-hole-compatible SMT assembly and supports JTAG-free ISP via Altera's classic programming algorithm using dedicated programming pins. Power consumption is moderate for the 5V CMOS process, and the device is specified over commercial and industrial temperature grades depending on sub-variant.
The EP610SC-20 uses Altera's classic EPLD architecture with EPROM-configured AND/OR arrays feeding 16 flip-flop-equipped macrocells. Each macrocell offers configurable D/T/JK flip-flop polarity, feedback paths, and output enable control. With 22 ns tPD and registered throughput up to 100 MHz, the architecture targets glue-logic, address decoding, state-machine, and bus-interface applications that benefit from instant-on non-volatile configuration. The CMOS EPROM cell provides bit-level reprogrammability with UV-windowed ceramic variants historically available for engineering development.
Typical applications include legacy industrial control board replacement, telecom infrastructure glue logic, address decoding and bus arbitration in 5V embedded designs, 5V state machines, and military/aerospace sustainment programs that require drop-in Altera-classic form-fit-function continuity. Rochester Electronics' ongoing manufacture makes the EP610SC-20 a viable long-term sustainment part.
When designing with this device, ensure your design fits within the 16 macrocell and ~300 gate-equivalent logic capacity, as overflow requires logic partitioning across multiple devices. Verify the 5V VCC tolerance of downstream logic since 5V CMOS outputs may exceed 3.3V tolerance of newer devices.

Aplicações típicas
EP610SC-20 é adequado para 6 aplicaçãos: Legacy Industrial Control Board Replacement, Telecom Infrastructure Glue Logic, 5V Address Decoding and Bus Arbitration, 5V State Machine Controllers, Military and Aerospace Sustainment, Legacy Peripheral and I/O Controller Replacement.
Legacy Industrial Control Board Replacement
The EP610SC-20 is ideal for sustaining legacy 5V industrial control boards where original Altera Classic EPLDs must be replaced without redesign. With 16 macrocells and 300 gate equivalents, it fits typical glue-logic functions such as I/O decoding, interrupt steering, and motor-control timing blocks that were originally implemented in EP610 silicon. The 22 ns tPD enables deterministic 5V state-machine operation at control-loop rates up to several hundred kHz without propagation-delay jitter. Designers can drop the SOIC-24 EP610SC-20 onto existing footprints that previously held Altera-marked parts, since Rochester Electronics produces pin-compatible authorized-source silicon. This avoids costly board respins for long-lifecycle factory automation, CNC, and process-control equipment that has been in service since the 1990s.
Recomendado
Telecom Infrastructure Glue Logic
In telecom backplane and line-card designs from the 1990s and early 2000s, the EP610SC-20 served as instant-on non-volatile glue logic for address decoding, bus arbitration, and timing-strobe generation. Its EPROM-configured macrocells power up in a known valid state within microseconds, unlike SRAM FPGAs that require configuration boot time - critical for telecom fault-recovery scenarios where the system must come back online without external intervention. The 5V CMOS I/O is compatible with legacy TTL/CMOS telecom ASICs and bus transceivers, while the 24-pin SOIC package fits densely populated line cards. With 100 MHz pipelined throughput available, the EP610SC-20 can drive address/control buses at telecom backplane speeds. Rochester Electronics' ongoing authorized manufacture keeps this part available for telecom OEM sustainment programs.
Recomendado
5V Address Decoding and Bus Arbitration
The EP610SC-20 is well suited for 5V address decoding and bus arbitration in VME, ISA, and proprietary embedded bus systems. Its 16 macrocells can implement multi-bank chip-select decoding, wait-state generation, and DMA arbitration logic with combinational tPD of 22 ns - sufficient for legacy 8/16-bit bus cycles at 25-33 MHz. Unlike discrete 74LS/74F glue logic, a single EP610SC-20 replaces dozens of decoder and latch packages, reducing PCB area and improving signal integrity on long bus traces. The EPROM non-volatile configuration means decoded address maps persist across power cycles without external PROMs. For designs migrating from 74-series logic to programmable logic at 5V, the EP610SC-20 in SOIC-24 offers a familiar footprint with predictable 5V CMOS timing.
Recomendado
5V State Machine Controllers
The EP610SC-20's 16 flip-flop-equipped macrocells implement complex 5V state machines with up to 16 states plus output logic. Each macrocell provides configurable D/T/JK flip-flop polarity, feedback paths, and output enable control - sufficient for protocols like SPI, I2C, UART, and legacy serial-control interfaces at MHz rates. The 22 ns tPD plus 100 MHz pipelined throughput allows state-machine outputs to be registered and re-driven within a single clock period, supporting deterministic real-time control. The EPROM-based configuration eliminates the boot-time delay of SRAM FPGAs, enabling instant-on behavior in safety-critical applications. Designers can implement multi-state sequencers, watchdog controllers, and protocol bridges in a single SOIC-24 EP610SC-20, replacing discrete 74HC logic arrays.
Recomendado
Military and Aerospace Sustainment
The EP610SC-20 family supports military and aerospace sustainment programs that must keep legacy avionics, radar, and weapons-system electronics operational beyond their original production lifecycle. Rochester Electronics' authorized-source status under the original Altera design provides qualified silicon for these long-lifecycle programs, often extending operational service for 20-30 years. The ceramic CERDIP-packaged EP610DC-20 variant is preferred for military temperature ranges and vibration-sensitive applications, while the SOIC-24 EP610SC-20 suits commercial-temperature aerospace systems. With 16 macrocells and 300 gate equivalents, the EP610 family handles interface adaptation, signal conditioning, and timing-control functions in systems where modern FPGAs are not approved for use.
Recomendado
Legacy Peripheral and I/O Controller Replacement
The EP610SC-20 is commonly used as a drop-in replacement for aging 5V peripheral and I/O controllers in industrial PCs, test equipment, and embedded controllers. Its 24-pin SOIC package and 5V CMOS interface match the original Altera EP610 footprint, allowing direct substitution on existing PCBs without board rework. With 16 macrocells, the device implements parallel-port expansion, SCSI termination control, GPIB handshake logic, and custom peripheral interfaces that have no modern equivalent. The 22 ns tPD enables peripheral timing compatible with legacy bus standards, while the EPROM configuration preserves custom logic across decades of operation. Rochester Electronics' active manufacture ensures continued availability for sustainment of legacy test-and-measurement and industrial-PC platforms.

Notas de projeto
The EP610SC-20 requires a stable 5V VCC supply with typical CMOS quiescent current in the tens of milliamps. Decouple VCC (pin 24) with a 0.1 uF ceramic capacitor placed within 5 mm of the supply pin, plus a bulk 10 uF tantalum or aluminum electrolytic at the board's power entry. The 5V CMOS I/O is not 3.3V tolerant - if interfacing to 3.3V logic, use 74HCT-series level shifters. Power sequencing is not required since the EPROM configuration is non-volatile.
Route the SOIC-24 EP610SC-20 with controlled-impedance traces if I/O toggles above 50 MHz. Place decoupling capacitors as close as possible to VCC (pin 24) and GND (pin 9), using short, wide traces to minimize inductance. Keep programming-pin traces away from switching signals to prevent noise coupling during configuration. For mixed-signal boards, isolate the EP610SC-20's ground return from high-current switching loads to avoid ground-bounce coupling into logic outputs.
Estimated: when migrating from the original Altera-marked EP610SC-20 to Rochester Electronics' authorized-source part, verify the pinout against the original Altera EP610 datasheet because Rochester's SOIC-24 package follows the same industry-standard pinout. Do not assume 3.3V tolerance - the EP610 family is pure 5V CMOS and outputs will damage 3.3V-only logic devices. For windowed CERDIP variants (EP610DC-20), use proper UV erasure procedures; OTP plastic versions cannot be re-programmed.
