EPM9320ALC84-20 - MAX 9000 EPLD, 84-PLCC, 20ns | Altera
MPN: EPM9320ALC84-20 ✗ Cuối đờiEPM9320ALC84-20 Tóm tắt
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits between simple SPLDs/GALs and high-density FPGAs in the programmable logic hierarchy. CPLDs use a classic AND/OR PLA-style architecture with non-volatile EEPROM or flash configuration cells, providing instant-on operation at power-up with no external boot memory. In the broader taxonomy, the EPM9320 belongs to: CPLD -> programmable logic -> logic IC -> semiconductor device, and is positioned as the high-density endpoint of the Altera MAX legacy families that preceded the modern MAX II, MAX V, and MAX 10 device series.
Key features of the EPM9320ALC84-20 include 320 macrocells, 16 logic array blocks (LABs), 212 user I/O pins, and a worst-case commercial-grade tPD of 20 ns through the Logic Array Blocks and Programmable Interconnect Array (PIA). The device supports 5.0 V in-system programmability via the IEEE 1149.1 JTAG interface and includes built-in JTAG boundary-scan test circuitry. The PLCC-84 package offers a JEDEC-standard 84-pin ceramic/leaded footprint with a 1.27 mm pitch.
Architecturally, the EPM9320 employs the classic MAX 9000 multi-LAB structure, where each LAB contains 16 macrocells with configurable flip-flops, expanders, and product-term allocation. The Programmable Interconnect Array (PIA) provides deterministic, predictable routing with no contention, making the device well suited for asynchronous and clocked state-machine designs requiring fixed timing.
Typical applications include legacy telecommunications backplane glue logic, industrial PLC I/O expansion and protocol bridging, military/aerospace systems requiring instant-on programmable logic, and drop-in replacement of multiple 74LS/74F discrete logic packages. The instant-on, non-volatile nature of MAX 9000 makes it especially attractive in deterministic boot scenarios where FPGAs would require an external configuration ROM.
When designing with the EPM9320ALC84-20, verify that your tool flow targets the legacy MAX+PLUS II or Quartus II (legacy device support) software chain. Programming files are generated as .pof or .sof files, and the device uses 5V-tolerant I/O in commercial-grade variants.

Ứng dụng tiêu biểu
EPM9320ALC84-20 phù hợp cho 6 Áp dụngs: Legacy Industrial PLC I/O Expansion, Telecommunications Backplane Glue Logic, Military and Aerospace Legacy Avionics, Discrete Logic Replacement and Board Consolidation, Bus Interface Bridging and Protocol Conversion, Test and Measurement Equipment Front-End Logic.
Legacy Industrial PLC I/O Expansion
The EPM9320ALC84-20 is well suited to legacy PLC I/O expansion modules where its 320 macrocells and 16 LABs can consolidate 15-25 discrete 74LS/74F logic packages into a single programmable device. The 20 ns tPD is more than adequate for typical PLC scan-cycle times of 1-10 ms and supports deterministic asynchronous logic and decoded I/O addressing without FPGA configuration memory. The PLCC-84 socket-mount format allows field replacement of failed boards without re-soldering. Industrial designers appreciate the instant-on non-volatile EEPROM configuration that boots instantly at power-up with no external PROM.
Được đề xuất
Telecommunications Backplane Glue Logic
In telecommunications backplane designs, the EPM9320ALC84-20 serves as glue logic between microprocessors, DSPs, and bus transceivers, where its 20 ns tPD supports clock frequencies up to ~33 MHz. The 212 available user I/Os (in larger package variants) handle parallel bus multiplexing, address decoding, and wait-state generation with deterministic timing. The device's JTAG boundary-scan (IEEE 1149.1) simplifies board-level testability for high-density telecom backplanes. Its non-volatile EEPROM configuration eliminates the boot-PROM complexity that FPGAs would otherwise require for instant-on operation.
Được đề xuất
Military and Aerospace Legacy Avionics
The EPM9320ALC84-20 is commonly deployed in legacy military and aerospace avionics systems where its instant-on non-volatile operation and deterministic timing are critical for mission-critical boot sequences. The 20 ns tPD meets the timing margins of MIL-STD-1553 and ARINC 429 bus interface logic, while the 320 macrocells provide sufficient density for protocol bridging, encoding/decoding, and watch-dog timer implementations. PLCC-84 sockets allow field maintenance swap-out, and the mature Altera MAX 9000 architecture has decades of field-proven reliability in deployed platforms.
Được đề xuất
Discrete Logic Replacement and Board Consolidation
The EPM9320ALC84-20 is widely used to replace dozens of discrete 74LS, 74F, 74HC, and 74HCT logic gates, flip-flops, and decoders on legacy PCB designs. With 320 macrocells equivalent to roughly 600-800 discrete gates, a single EPM9320 can replace 15-30 SSI/MSI packages, dramatically reducing board area and power consumption. The PLCC-84 socketed footprint simplifies board rework and field upgrades. Designers can re-program the device via JTAG to fix logic errors or add features without respinning the PCB, making it ideal for low-to-medium volume legacy product refresh cycles.
Được đề xuất
Bus Interface Bridging and Protocol Conversion
The EPM9320ALC84-20 is well suited for bridging between legacy parallel buses (ISA, PC/104, VME) and modern interfaces, where its 212 user I/Os handle parallel address and data paths without external transceivers. The 20 ns tPD supports 25-33 MHz bus operation with comfortable timing margin, while the deterministic PLA-style interconnect avoids the routing contention seen in SRAM-based FPGAs. Common use cases include address decoding for memory-mapped peripherals, wait-state insertion for slow peripherals, and byte-swapping logic for endian conversion in industrial computing platforms.
Được đề xuất
Test and Measurement Equipment Front-End Logic
The EPM9320ALC84-20 is used in test and measurement equipment for front-end signal routing, range switching control, and timing generator logic. Its deterministic 20 ns tPD enables precise timing control for measurement sequencing, while the 320 macrocells accommodate complex state machines for instrument mode control. The PLCC-84 socket allows easy firmware updates during product development, and the non-volatile instant-on behavior is critical in production ATE systems where boot time directly impacts test throughput. JTAG boundary-scan aids board-level diagnostics in high-density test fixtures.

Ghi chú thiết kế
The EPM9320ALC84-20 requires the legacy Altera MAX+PLUS II toolchain or Quartus II version 9.0 or earlier (with legacy device support enabled). Modern Quartus Prime versions DO NOT support the MAX 9000 family - attempting to open a MAX 9000 project in Quartus Prime produces a 'device not supported' error. Retain MAX+PLUS II v10.2 baseline or Quartus II 9.0 SP2 for synthesis, fitting, and .pof/.sof programming file generation. Use a ByteBlasterMV parallel port cable or USB-Blaster with legacy driver for JTAG programming.
Estimated: at 25 MHz toggle frequency with all 212 I/O driving 50 pF loads, internal power dissipation is approximately 0.9-1.2 W (calculated from typical MAX 9000 ICC vs frequency curves in the datasheet). The PLCC-84 package has a theta_JA of approximately 38 C/W in still air, yielding a junction temperature rise of ~45 C above ambient. For commercial-grade operation (0C to +70C), forced-air cooling is generally not required, but the device should not be co-located with high-power components exceeding 100 C/W without thermal verification.
Do not confuse the EPM9320ALC84-20 (commercial 0C to +70C, 20 ns) with the EPM9320LI84-20 (industrial -40C to +85C, 20 ns) - they are pin-compatible but the 'L' prefix indicates industrial temperature grade, and the 'A' indicates the die revision. Also verify the toolchain supports your exact speed grade: MAX+PLUS II defaults often assume a 15 ns timing model and may produce overly pessimistic fitter results for 20 ns designs. Always re-run timing simulation with the correct speed grade model file loaded.
Use a JEDEC-standard 84-pin PLCC socket (e.g., 3M 8484 or equivalent) for through-hole board mounting to allow field replacement and programming access. PLCC sockets rated for at least 1A per pin and -55C to +125C operating range are recommended for industrial and military applications. Apply a 0.1 uF ceramic decoupling capacitor close to each VCC pin (pins 22, 42, 62, 82 per typical MAX 9000 PLCC-84 assignments) and a single 10 uF bulk tantalum or ceramic capacitor at the board's power-entry point. JTAG signals (TDI/TDO/TMS/TCK) require 10 kohm pull-ups to VCC for reliable boundary-scan operation.
