EP610SC-15 - 16-Macrocell Classic EPLD, 15ns tPD | Altera (Intel)
MPN: EP610SC-15 ✗ Cuối đờiEP610SC-15 Tóm tắt
An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device sitting between simple PAL/GAL architectures and modern FPGAs/CPLDs in the programmable logic hierarchy. The Classic family uses a sum-of-products AND/OR structure with a programmable macrocell, allowing designers to implement glue logic, state machines, address decoding, and bus interfacing in a single chip that retains its configuration when power is removed. This product category sits between discrete 74-series logic gates and modern complex programmable logic devices (CPLDs), offering deterministic 15 ns timing without the need for JTAG or in-system programming.
Key features include a maximum operating frequency in the tens of MHz range (fMAX around 83 MHz typical for the -15 speed grade), 24 input/output pins, 16 macrocells, low CMOS standby current, and a JEDEC-standard 24-pin 300-mil SOIC package. The part supports both combinatorial and registered logic modes through its macrocell flip-flop, with independent feedback paths into the AND array. Programming is performed via a standard EPROM-style algorithm and the configuration is erased with a UV window (the ceramic-windowed variants such as the EP610LC series), while the 'SC' commercial plastic package is one-time-programmable for production volumes.
Typical applications include TTL/CMOS logic replacement, bus address decoding and chip-select generation, state machines for peripheral controllers, encoder/decoder logic, and interface glue between microprocessors and peripherals. Its deterministic 15 ns timing and 5 V interface make it especially suitable for legacy industrial control boards, telecommunications backplane cards, and instrumentation front-ends that require bus-interface logic without software-driven PLD configuration.
When designing with the EP610SC-15, ensure that the 24-pin SOP land pattern matches the JEDEC SO-24 300-mil footprint. Decoupling should include a 0.1 µF ceramic capacitor as close as possible to the VCC and GND pins. Designers migrating to lower-density CPLDs from Lattice or Xilinx should verify pinout compatibility because the EP610's pin ordering is specific to the Classic family. This page consolidates distributor pricing, drop-in speed-grade alternatives within the EP610 family, and practical design notes beyond the manufacturer datasheet.

Ứng dụng tiêu biểu
EP610SC-15 phù hợp cho 6 Áp dụngs: TTL/CMOS Logic Replacement, Bus Address Decoding and Chip Select Generation, State Machines for Peripheral Controllers, Encoder / Decoder and Protocol Translation, Legacy Industrial Control Board Glue Logic, Instrumentation Front-End Logic.
TTL/CMOS Logic Replacement
The EP610SC-15 is well-suited for replacing multiple discrete 74-series TTL/CMOS SSI/MSI gates with a single programmable device. With 16 macrocells and 300 usable gates plus a deterministic 15 ns pin-to-pin delay, the EP610SC-15 can consolidate dozens of glue-logic gates into one chip, reducing PCB area, BOM count, and overall system cost. Designers port a TTL logic schematic into a JEDEC fuse map and program the part once via standard EPROM hardware. The 5 V single-supply operation matches existing TTL logic rails with no level shifting. Compared to a discrete gate implementation, the EP610SC-15 also provides design flexibility: late-stage logic changes only require a re-programmed fuse map, not a PCB re-spin.

Bus Address Decoding and Chip Select Generation
The EP610SC-15's 16 macrocells and 24 pins are sufficient to implement address decoders, chip-select logic, and wait-state generators for microprocessor and microcontroller systems. With its 15 ns propagation delay, the EP610SC-15 can decode addresses and assert chip-selects within one clock cycle of 8-bit and 16-bit microprocessors running up to 30-40 MHz. Each macrocell supports registered or combinatorial outputs, allowing fully synchronous or asynchronous decoding. The part's 5 V TTL interface matches legacy 8086, 68000, 8051, and similar microprocessors without level translation. Designers configure the AND/OR array once and get a single-chip replacement for a board full of 74LS138/139/151/688 decoders.

State Machines for Peripheral Controllers
The EP610SC-15 implements Moore and Mealy state machines for peripheral controllers, printers, motor control sequencers, and protocol converters. Its 16 macrocells provide enough flip-flops for 4-bit (16-state) to 8-bit (256-state) machines, and the macrocell architecture supports both registered output and combinatorial feedback, ideal for FSM design. With 15 ns timing the part can drive state-machine outputs synchronously to clocks up to 66 MHz (fMAX), giving ample margin for most UART, SPI, I2C, and parallel-port sequencer applications. The OTP plastic package is suitable for high-volume production where the state machine is fixed. The 5 V CMOS interface is directly compatible with common peripheral ICs and opto-isolated industrial inputs.
Được đề xuất
Encoder / Decoder and Protocol Translation
The EP610SC-15 fits encoder/decoder applications such as Manchester, NRZ, BCD-to-7-segment, and Hamming-code generation. Its 24 pins include up to 16 I/O plus dedicated input and clock pins, sufficient for 8-to-16-bit encoders, 7-segment display drivers, and simple error-correction encoders. The 15 ns timing supports bit rates up to about 30 Mbps in pipelined encoder topologies. Because each macrocell has its own flip-flop and feedback, the EP610SC-15 can implement both the encoder logic and the output register in a single device. The 5 V single supply and CMOS output drive are suitable for direct interface to legacy instrumentation buses and panel meters.

Legacy Industrial Control Board Glue Logic
The EP610SC-15 is a go-to glue-logic device for legacy industrial control boards, factory automation cards, and backplane interface cards. Its 5 V TTL interface, 24-pin SOIC footprint, and 15 ns deterministic timing make it a drop-in logic integration device for PLC I/O cards, motor-driver interface boards, and process-control front-ends. Compared to a full CPLD, the EP610SC-15 has simpler timing closure and lower cost for low-density functions such as relay de-bouncing, encoder quadrature decoding, and PWM safety interlocks. Rochester Electronics continues to supply the part for industrial customers with long-life product support requirements. The OTP plastic package is well-suited for sealed industrial installations.
Được đề xuất
Instrumentation Front-End Logic
The EP610SC-15 is used in instrumentation front-ends for range selection, gain switching, multiplexer control, and trigger logic. Its low-noise CMOS architecture adds minimal noise to sensitive analog signal chains, while the 5 V interface is compatible with precision ADCs, DACs, and analog switches. The 15 ns timing supports real-time range-switching in oscilloscope and data-acquisition front-ends. Each macrocell can drive analog switches such as the DG408 or the ADG708 directly via a few hundred ohms of output impedance. Designers value the deterministic timing because instrumentation channels often require glitch-free switching at known instants relative to ADC sample clocks.

Ghi chú thiết kế
Mount the EP610SC-15 in the JEDEC-standard 24-pin 300-mil SOP (SOIC-24) footprint with a top-side 0.1 µF ceramic decoupling capacitor placed within 5 mm of the VCC pin (pin 24) and a 0.1 µF ceramic on the GND pin (pin 12). The exposed lead frame is not present, so thermal dissipation is limited to the 8 ground leads; the part typically dissipates under 200 mW. Provide a 50 mm² copper pour on VCC and GND for additional heat spreading. Avoid running high-speed traces underneath the device to minimize coupling into the macrocell inputs.
Clock and registered-input signals must be routed with controlled impedance if they exceed 50 MHz; for typical 33-66 MHz designs, keep traces short and place a 33 Ω series-termination resistor near the driver if multiple EP610SC-15 inputs share a clock. The Classic family does not have Schmitt-trigger inputs, so noisy or slowly-rising inputs may cause macrocell oscillation. Add a hysteresis resistor (1-10 kΩ) on the clock pin if the source is mechanical (switch contact) or long-line (>100 mm). Keep high-current switching signals (relay coils, bus drivers) at least 10 mm from any analog input.
Estimated: EP610SC-15 propagation delay is 15 ns at room temperature with nominal 5 V supply; designers operating near the timing limit should add 20% margin to account for temperature and voltage variation. Do not substitute the EP610LC-15 (28-pin PLCC) on a 24-pin SOP board - pinouts differ. Do not connect unused macrocell I/O pins to VCC or GND directly; configure them as outputs driving a defined state via the JEDEC fuse map, or leave them floating if the device is in a socket. Programming the part with a wrong JEDEC file silently corrupts the function - verify with a functional tester before conformal coating or potting.
