EPM9320RC208-10 概述
A CPLD (Complex Programmable Logic Device) is a non-volatile, flash- or EPROM-based programmable logic device that sits between simple PAL/GAL devices and FPGAs in the programmable logic hierarchy. CPLDs typically provide deterministic pin-to-pin propagation delays, instant-on behavior, and a small number of high-drive I/O banks, which makes them ideal for glue logic, bus decoding, state-machine implementation, and power-sequencing control. The MAX 9000 family from Altera (now Intel Programmable Solutions Group) was one of the higher-density CPLD families of its era, extending the MAX architecture with more macrocells and broader I/O counts.
Key features of the EPM9320RC208-10 include the 208-pin RQFP package (commercial 'RC' suffix denotes commercial temperature range), the 5 V VCCIO/VCCINT core supply typical of the MAX 9000 family, and 320 macrocells organized into Logic Array Blocks (LABs). The device supports in-system programmability via the Altera ByteBlaster or BitBlaster JTAG interface and is supported by the legacy MAX+PLUS II and Quartus design toolchains. The -10 speed grade defines the worst-case pin-to-pin tPD, which is documented in the MAX 9000 datasheet family.
Typical applications for this part include legacy glue-logic replacement, address decoding for 8/16/32-bit microprocessor buses (Intel 80x86, Motorola 68k, MIPS), 5V system bus arbitration, and pin-compatible upgrades for earlier -15 or -20 speed grades where timing margin allows. The non-volatile architecture means the device retains configuration without external boot memory, simplifying board design and reducing BOM cost in industrial control and telecom infrastructure.
When designing with the EPM9320RC208-10, engineers should note that the MAX 9000 family is in NRND/last-time-buy status and new designs should target MAX II, MAX V, or MAX 10 families instead. For legacy board repair, the -15 and -20 speed grade variants are pin-compatible upgrades that simply derate timing.

典型应用
EPM9320RC208-10 适用于 6 应用s: Legacy Microprocessor Bus Decoding, Industrial Control Glue Logic, Telecom Infrastructure Backplane Logic, Avionics and Military Legacy Systems, Test and Measurement Equipment, Power Sequencing and Reset Control.
Legacy Microprocessor Bus Decoding
The EPM9320RC208-10 fits legacy 8/16/32-bit microprocessor address decoding thanks to its 320 macrocells and 208-pin RQFP I/O capacity, which provides enough programmable logic to implement full address-decode trees, chip-select generators, and wait-state controllers on Intel 80x86, Motorola 68k, or MIPS buses. With deterministic pin-to-pin tPD typical of MAX 9000 CPLDs, the device introduces well-defined propagation delay into decode paths - critical for legacy CPU subsystems without onboard chipset logic. The non-volatile EPROM-based configuration means the board boots with the decoder logic active instantly, eliminating external boot memory. Compared to discrete 74LS/74F glue logic, a single EPM9320 replaces dozens of decoders and latches, reducing PCB area and improving reliability in industrial single-board computers and telecom control cards. For new designs, MAX II/MAX V equivalents are recommended, but for sustaining legacy 5 V systems the EPM9320RC208-10 remains a practical choice.
推荐
Industrial Control Glue Logic
The EPM9320RC208-10's 5 V single-supply operation and 320 macrocells make it well-suited to industrial PLC, motor-drive, and process-control board glue logic where 5 V rails remain standard. CPLD non-volatility guarantees the PLC or drive controller powers up in a deterministic state without external configuration memory - essential for safety-critical industrial equipment that must not enter undefined states on brown-out or cold-start. The 208-pin RQFP package provides more than 150 user I/O, enough to interface parallel ADC/DAC buses, encoder inputs, and discrete I/O modules. Industrial temperature variants (EPM9320ARI208-10) share the same die for harsh environments. Compared to multiple discrete PAL/GAL devices, a single EPM9320 simplifies BOM, improves test coverage via JTAG boundary-scan, and allows last-minute logic changes via software updates rather than board respins.
推荐
Telecom Infrastructure Backplane Logic
The EPM9320RC208-10 serves telecom backplane applications requiring high-I/O-count glue logic, including T1/E1 framer interfacing, HDLC controller bridging, and bus-isolation logic on legacy ATM and SONET line cards. The 208-pin RQFP I/O capacity supports the wide parallel data buses used in 1990s-2000s telecom infrastructure, while the deterministic CPLD timing model simplifies worst-case timing closure across multi-board backplane designs. The non-volatile configuration eliminates the boot-time flash-loading sequence required by SRAM-based FPGAs of similar density, reducing in-service interrupt risk for telecom line cards that must come online instantly. The 5 V supply is compatible with telecom Power-Over-Ethernet and -48 V-to-5 V isolated DC-DC converter rails. For maintaining legacy central-office equipment, the EPM9320RC208-10 is often the only practical substitute for original MAX 9000 designs.
推荐
Avionics and Military Legacy Systems
The EPM9320RC208-10 in the 208-RQFP package is used in legacy military and avionics subsystems where reliability and long-term availability outweigh density requirements. The MAX 9000 family has extensive flight heritage on platforms dating from the 1990s, and its non-volatile EPROM/EEPROM configuration is immune to radiation-induced configuration upset that affects SRAM FPGAs - a key advantage for avionics and aerospace applications. Industrial temperature variants (EPM9320ARI208-10) extend operating range for avionics bay environments. The deterministic timing supports MIL-STD-1553, ARINC 429, and other legacy avionics bus decoder implementations. For modern redesigns, MAX 10 or radiation-hardened FPGAs are preferred, but for sustaining fielded avionics, the EPM9320 remains the proven incumbent.
推荐
Test and Measurement Equipment
The EPM9320RC208-10's 320 macrocells and 208-pin RQFP I/O make it appropriate for digital pattern generators, logic analyzers, and protocol testers requiring custom timing and sequencing logic. The deterministic CPLD propagation delay is advantageous in test equipment where synthesized logic must generate precise timing edges to stimulate DUTs. The 5 V I/O compatibility matches legacy TTL/CMOS instrumentation buses (GPIB, VXI), and the JTAG interface supports in-system reconfiguration for different test patterns. Compared to microcontrollers, the CPLD provides deterministic cycle times without interrupt latency - critical for protocol testers. The MAX 9000 family's BitBlaster/ByteBlaster JTAG chain also allows fixture-level programming during test fixture build, accelerating NPI test development.
推荐
Power Sequencing and Reset Control
The EPM9320RC208-10's 320 macrocells are well-suited to multi-rail power-sequencing controllers used in legacy 5 V/3.3 V/2.5 V mixed-voltage systems. The CPLD can implement reset-generation, watchdog timers, voltage-monitor coordination, and programmable power-up/power-down sequencing across multiple DC-DC converters - replacing discrete supervisory ICs and timer chains. The deterministic pin-to-pin timing ensures repeatable sequencing intervals, while the non-volatile configuration guarantees the correct sequence after brown-out or cold-start. The 208-RQFP I/O count supports sequencing controllers for up to 8-12 independent power rails. JTAG in-system programmability allows sequencing logic updates during board bring-up without hardware changes. For modern PMBus/sequencer IC replacements, the MAX 9000 remains a viable sustaining-solution in field-deployed telecom and industrial equipment.

设计说明
The EPM9320RC208-10 is in NRND (Not Recommended for New Designs) status as of 2026-09-13. Do NOT use this part in new designs. For new CPLD designs, Intel recommends the MAX II (EPM240/G), MAX V (5M240ZE100), or MAX 10 (10M02) families, which require PCB redesign but provide modern features, lower power, and active lifecycle support. The EPM9320RC208-10 should be reserved exclusively for legacy board repair and maintenance.
The 208-pin RQFP package requires careful PCB layout: keep all 208 traces short and matched where bus-impedance matters, use a 4-layer PCB with continuous ground plane under the device for thermal dissipation and EMI suppression, and provide 0.1 uF decoupling capacitors adjacent to every VCC/VCCIO pin pair. JTAG TCK, TMS, TDI, TDO traces should be length-matched and routed away from switching signals to avoid programming-time errors.
The MAX 9000 family uses a 5 V VCCINT and typically 5 V or 3.3 V VCCIO (per-pin I/O bank voltage). When migrating from -10 to -15 or -20 speed grade variants for supply continuity, verify that your timing closure budget tolerates the slower tPD. Estimated: at 25C ambient with typical 5V/3.3V I/O switching activity, the EPM9320 dissipates approximately 0.5-1.5 W - confirm with the MAX 9000 family datasheet ICC vs frequency graph for your design's actual toggle rate.
