EP610DC-30 - Classic EPLD, 16 Macrocells, 30ns | Altera
MPN: EP610DC-30 ✗ Tapus ng BuhayEP610DC-30 Ulas
A Classic EPLD is an early-generation programmable logic device that uses EPROM cells to store the configuration. In the broader taxonomy, the EP610DC-30 sits inside the PLD (Programmable Logic Device) family, which is a subset of programmable logic alongside CPLDs and FPGAs. EPLDs were widely adopted in the late 1980s and 1990s as a means of replacing discrete 74-series TTL/MSI glue logic, integrating state machines, address decoders, bus arbiters, and counter/timer functions into a single non-volatile, one-time-programmable (windowed-erasable UV) IC. The Classic device family preceded the MAX series and offers pin-to-pin compatibility across the EP610 and EP910 lines.
Key features include 16 macrocells organized in 4 Logic Expanders, 16 dedicated input pins, and 16 I/O pins with output enable control, plus a programmable clock with global and per-macrocell options. The EP610DC-30 supports a maximum toggle frequency of 100 MHz in pipelined mode, delivers a tPD (pin-to-pin propagation delay) of 30 ns in commercial temperature grade, and offers both registered and combinatorial output modes. The device also features a synchronous preset and asynchronous clear network, plus a security bit to protect proprietary designs after programming.
Architecturally, the EP610DC-30 uses a sum-of-products (AND-OR-XOR) PLA-like structure with a global interconnect that routes the 16 inputs and 16 feedback paths into 4 Logic Expanders, each producing 4 product terms per macrocell. The JEDEC-standard 24-pin ceramic DIP package supports through-hole mounting, which is typical for legacy and aerospace applications where socketed, field-replaceable logic remains preferred.
Typical applications include TTL/MSI glue-logic replacement in industrial controllers, address decoding in 8-bit and 16-bit microprocessor systems (such as 8086 and 68000 bus interfaces), state-machine implementations in telecom and instrumentation, and aerospace/avionics systems requiring ceramic-package reliability. Designers transitioning from 74LS/74ALS logic to a programmable equivalent often select this part for its predictable timing and EPROM non-volatility.
When designing with the EP610DC-30, note that ceramic DIP packages require through-hole PCB footprints and are not compatible with modern surface-mount assembly processes. Programming requires a UV-erasable window (no in-system programmability), and design entry uses legacy tools such as Altera MAX+PLUS II or the older A+PLUS environment. Designers should verify second-source availability (Rochester Electronics and Intel/Altera continue to manufacture this part) before committing to new designs.

Tipikal na mga Gamit
EP610DC-30 ay nararapat para sa 6 aplikasyons: TTL/MSI Glue Logic Replacement, Microprocessor Address Decoding, State Machine Implementation, Aerospace & Avionics Systems, Industrial Control Systems, Legacy Test & Measurement Instrumentation.
TTL/MSI Glue Logic Replacement
The EP610DC-30 replaces discrete 74LS/74ALS TTL logic by integrating address decoders, bus arbiters, and combinational glue into one non-volatile device. With 16 macrocells and 300 usable gates it can absorb 4-8 SSI/MSI packages, and its 30 ns tPD matches 74LS timing within tolerance. The EPROM non-volatility means logic is available at power-up with no boot sequence, unlike SRAM-based alternatives. The 24-pin CERDIP package drops onto standard through-hole PCB footprints designed for legacy 74LS replacement boards, simplifying field upgrades.
Inirekomenda
Microprocessor Address Decoding
The EP610DC-30 implements address decoding for 8-bit and 16-bit microprocessor systems including 8086, 68000, and Z80 designs. Its 16 dedicated inputs accept full address buses plus control signals (/RD, /WR, /MREQ), and 16 I/O pins produce chip-select outputs for memory and peripheral mapping. The 30 ns propagation delay fits comfortably within the address-to-CS timing window of 8 MHz 8086 and 10 MHz 68000 systems. JEDEC-standard programming files integrate the decoder into one package, replacing 2-3 PAL16L8/20L8 devices.
Inirekomenda
State Machine Implementation
The EP610DC-30 implements Moore and Mealy state machines for instrumentation, telecom, and control applications where deterministic, non-volatile logic is required. Each macrocell supports registered output with synchronous preset and asynchronous clear, and the 4 Logic Expanders provide product-term sharing for large state encodings. With 100 MHz maximum pipelined clock frequency and 30 ns tPD, the device handles telecom bit-rate processing up to 33 MHz comfortably. The EPROM storage means the state machine boots to a known state at power-on.
Inirekomenda
Aerospace & Avionics Systems
The EP610DC-30's ceramic DIP package with UV-erasable window satisfies aerospace and avionics reliability requirements where plastic packages and surface-mount only footprints are unacceptable. The part is used in long-life avionics subsystems including flight-control interfaces, navigation displays, and legacy radar signal processors that require 20+ year field support. Rochester Electronics' continuing-manufacture program guarantees supply for aerospace-grade customers throughout the platform lifecycle. The through-hole CERDIP package also enables socketed field replacement, important in MRO scenarios.
Inirekomenda
Industrial Control Systems
The EP610DC-30 drives discrete I/O expansion, motor-control timing, and PLC ladder-logic equivalent functions in legacy industrial controllers. Its 16 I/O pins interface directly to 5V CMOS/TTL industrial buses, and its EPROM non-volatility ensures controllers come up in a deterministic safe state at power-on - critical for safety-rated industrial machinery. The 30 ns tPD suits PLC scan times of 10-20 ms typical, where the EPLD performs sub-millisecond I/O decoding. Industrial customers value the part's predictable long-term availability via Rochester Electronics.
Inirekomenda
Legacy Test & Measurement Instrumentation
The EP610DC-30 implements timing generators, pulse-width modulators, and counter/timer chains in benchtop and ATE test equipment. Its 100 MHz pipelined clock capability and 16 macrocells produce 4-6 channels of independently programmable timing signals. The CERDIP package allows through-hole PCB assembly consistent with 1980s-1990s instrument designs still in field service. The EPROM non-volatility eliminates configuration memory and simplifies calibration procedures - the instrument powers up ready to measure.

Talaan ng Disenyo
The EP610DC-30 ceramic DIP package requires through-hole PCB mounting - it is NOT compatible with surface-mount assembly processes. Verify your board has DIP-24 footprints before sourcing this part. For new designs requiring SMD assembly, consider the Altera/Intel MAX series (EPM7032S in TQFP-44) which provides in-system programmability and modern footprints.
Place 0.1uF decoupling capacitors as close as possible to the VCC (pin 23) and GND (pin 12) pins of the EP610DC-30. For multi-EPLD designs, use a 10uF bulk tantalum capacitor at the power-entry point. Route the global clock (pin 18) with a 50-ohm controlled-impedance trace if operating above 25 MHz to avoid clock-distortion issues. The UV-erase window requires clearance above the package for erasure access.
The EP610DC-30 is NOT in-system programmable - design changes require a UV eraser (15-30 min exposure at 12 mW/cm^2) and a device programmer supporting the JEDEC-standard EP610 bitstream. Modern design flows use legacy tools (Altera MAX+PLUS II or A+PLUS), not Quartus. Plan for at least one development cycle per design iteration to allow UV erase and reprogram cycles.
Impormasyon ng Pagsunod sa Kautusan
Ceramic DIP package with UV window typically contains lead-bearing solder/glass. Not RoHS compliant due to ceramic-package materials. AEC-Q100 not applicable - this is a programmable logic IC, not an automotive-grade semiconductor in the modern AEC sense. Aerospace and avionics customers use this part under legacy qualification programs.
