EP610PC-30 - 16-Macrocell Classic EPLD, 30ns, PDIP-24 | Altera
MPN: EP610PC30 ✗ Cuối đờiEP610PC30 Tóm tắt
A PLD (Programmable Logic Device) is a digital integrated circuit whose internal logic structure and interconnect are user-configurable after manufacture, allowing engineers to implement custom glue logic, state machines, address decoding, and bus arbitration without committing to a custom ASIC. Within the broader taxonomy, the EP610 sits at: PLD -> EPLD (erasable, UV-window package optional) -> Classic EPLD family -> small-scale (16-macrocell) glue-logic segment. Compared to early bipolar PALs, the EP610 family added CMOS low power consumption, macrocell-based architecture (sum-of-products plus an output register), and erasable programming.
Key features of the EP610PC-30 include 16 macrocells with configurable output polarity and feedback, 300 usable gates of logic capacity, pin-to-pin propagation delay of 30 ns (commercial speed grade), a maximum toggle frequency of 33.3 MHz, and an internal EPROM/EEPROM-based configuration memory (the Classic family uses UV-erasable or one-time-programmable cells). The device also exposes a dedicated JTAG/serial programming interface and supports in-system or device-programmer configuration via Altera's MAX+plus II legacy toolchain.
Architecturally, the EP610 implements a programmable AND/OR array feeding 16 output macrocells, each containing a sum-of-products term generator plus a configurable D/T flip-flop. This architecture delivers deterministic, fixed-pin propagation delays (no routing-dependent timing), which simplifies timing closure in legacy 5 V designs versus early FPGAs. The classic EPLD is non-volatile - configuration is retained after power-down without external configuration memory.
Typical applications include 5 V bus-interface glue logic (ISA, VME, and STD-bus address decoding), state machines for industrial control boards, peripheral chip-select generation in legacy computing platforms, parallel-port decoding, and replacement of multiple discrete 74-series TTL gates in compact through-hole designs. The PDIP-24 package is well-suited to breadboard prototyping, educational lab kits, and through-hole industrial controllers where socketed, user-replaceable logic is preferred.
When designing with this part, note that the -30 speed grade trades off roughly 50 percent of toggle frequency versus the -15 grade, so verify that 33.3 MHz toggle / 30 ns pin-to-pin delay is sufficient for the target clock domain. For modern 3.3 V or lower-voltage systems, a level translator or a current-generation MAX II / MAX V CPLD is recommended.

Ứng dụng tiêu biểu
EP610PC30 phù hợp cho 6 Áp dụngs: 5V ISA/VME Bus Address Decoding, Industrial Control State Machines, Parallel-Port and Peripheral Chip-Select Generation, Legacy TTL Glue-Logic Consolidation, Educational PLD Laboratory Kits, Avionics and Military Legacy Replacement.
5V ISA/VME Bus Address Decoding
The EP610PC-30 is well-matched to legacy 5V ISA and VME bus address-decoding applications because its 16 macrocells provide sufficient sum-of-products terms for full 24-bit address decode, while the 30 ns tPD comfortably meets ISA's 8 MHz / 125 ns cycle budget with margin. The non-volatile EPROM configuration means no external boot PROM is needed, simplifying the BOM versus early FPGAs. Placed between the bus transceivers and peripheral chip-select pins, the EP610PC-30 replaces multiple 74LS138/688 decoder pairs with a single socketed device, simplifying PCB rework. Trade-off: the 5V-only supply and 30 ns speed grade make it unsuitable for 3.3V PCIe or modern MCUs.

Industrial Control State Machines
In industrial control boards and PLC-style sequencers, the EP610PC-30's 16 macrocells each containing a D/T flip-flop make it an efficient single-chip state machine for stepper control, conveyor sequencing, and I/O scanning. The 30 ns tPD supports deterministic state transitions up to ~33 MHz, and the PDIP-24 through-hole package is socket-friendly, allowing field replacement in legacy factory equipment. Industrial designers appreciate the non-volatile configuration that survives power-down without battery backup, plus the extended-temperature -LI suffix option (EP610LI-30) for harsh environments. Trade-off: for state machines exceeding 16 states or requiring complex arithmetic, a larger MAX V CPLD is recommended.

Parallel-Port and Peripheral Chip-Select Generation
The EP610PC-30 is ideal for generating peripheral chip-select signals in legacy parallel-port designs, PC/104 stacks, and embedded SBCs where multiple peripherals share a single bus. With 16 macrocells, designers can implement 8-16 independent chip-select decoders with strobe qualification, all in one socketed device. The 30 ns tPD easily fits within the 100-200 ns access windows of MFM/IDE hard-disk controllers and parallel-port peripherals. Placed between the address bus and peripheral CE pins, the EP610PC-30 consolidates what would otherwise require 3-4 discrete decoder ICs. Trade-off: modern USB-based peripherals do not require this glue logic.

Legacy TTL Glue-Logic Consolidation
Designers replacing scattered 74LS/74F-series TTL gates benefit from the EP610PC-30's ability to absorb 4-6 SSI/MSI packages into one socketed PLD, reducing PCB area and improving serviceability. With 300 usable gates and 16 macrocells, a single EP610PC-30 can implement address decoding plus a few small state machines plus custom timing logic. The PDIP-24 form factor is breadboard-friendly for prototype labs and educational courses teaching PLD design with Altera's classic MAX+plus II toolchain. Trade-off: the -30 speed grade limits use in 50 MHz+ glue-logic paths; the -25 or -20 grade is preferred there.

Educational PLD Laboratory Kits
Universities and technical colleges use the EP610PC-30 in digital-logic laboratories because its PDIP-24 through-hole package fits standard solderless breadboards and IC sockets, and its 5V supply matches common lab power rails. Students learn programmable logic fundamentals - sum-of-products, macrocell flip-flops, JTAG programming - on a part that has decades of teaching material available. The MAX+plus II legacy toolchain runs on modern Windows machines via compatibility mode, supporting coursework continuity. Trade-off: universities transitioning to FPGA-based teaching now pair the EP610PC-30 with a modern dev board for comparative labs.
Được đề xuất
Avionics and Military Legacy Replacement
The EP610PC-30 is widely used to sustain legacy avionics, radar, and military systems where the original Altera parts were specified decades ago. Sustained by Rochester Electronics, the EP610PC-30 (and its -DM/883B MIL-STD-883 variant) provides drop-in replacement for obsolete inventory, extending the service life of fielded equipment. The 30 ns tPD and 16-macrocell architecture exactly match original specifications, eliminating the need for board re-design or re-qualification. Trade-off: for new military designs, modern radiation-hardened FPGAs are required; the EP610 is a sustainment-only part.

Ghi chú thiết kế
The EP610PC-30 requires a single +5V +/-10% supply on pin 24 with a 0.1 uF ceramic decoupling capacitor placed within 5 mm of the VCC pin. The device is CMOS technology but its 16 macrocells switching simultaneously at 33.3 MHz can produce transient currents up to ~50 mA, so bulk decoupling (10 uF tantalum) at the supply rail is recommended. Estimated: ICC is not explicitly stated in the public datasheet excerpt, but Classic EP610 family typical ICC at 33 MHz is 30-60 mA. Always decouple VCC to GND pin 12 with both high-frequency and bulk capacitors.
Place the EP610PC-30 in a DIP socket (e.g., 24-pin machined-pin socket) for prototyping and field serviceability - the part is through-hole and legacy systems frequently require socketed replacement. Keep trace lengths on all 16 I/O pins under 50 mm to avoid reflections; this device is designed for slow, board-level signal rates, not high-speed transmission lines. Provide a ground plane under the device to reduce switching noise on adjacent analog sections. The non-volatile EPROM configuration means no programming header footprint is required on the production PCB.
Do not assume the EP610PC-30 is pin-compatible with the EP600 family - they share the Classic EPLD heritage but have different pinouts, JTAG IDs, and programming bitstreams; substituting one for the other will fail configuration. Do not operate at VCC below 4.5 V or above 5.5 V - the EPROM read margin degrades outside this range. Do not use the EP610PC-30 in new 3.3V designs; use a modern MAX II/MAX V CPLD with level translators. When programming with MAX+plus II, always select the exact device variant (-30 speed grade) - mis-selection produces bitstreams that appear to work but have timing violations.
The EP610PC-30 in PDIP-24 has a junction-to-ambient thermal resistance (theta_JA) of approximately 60-70 C/W (estimated for plastic DIP packages of this pin count). At typical 5V / 30 mA ICC, power dissipation is ~150 mW, producing a junction temperature rise of ~10 C above ambient - well within commercial operating limits. Designers using the industrial-grade EP610LI-30 variant must still verify thermal margin in enclosed housings, as the -40C to +85C operating range does not waive thermal derating.
