EPM9320RI208-10N 概述
A CPLD (Complex Programmable Logic Device) is a programmable logic IC that combines multiple PAL-like logic blocks with a programmable interconnect matrix on a single die. In the broader hierarchy, a CPLD sits between simple programmable logic devices (SPLDs) and full FPGAs: CPLDs offer deterministic, non-volatile timing and instant-on operation, while FPGAs provide higher logic density. The MAX 9000 family extends the classic MAX 7000 architecture with higher macro cell counts and multiple I/O banks, targeting glue-logic consolidation, bus bridging, and state-machine implementations.
The EPM9320RI208-10N provides 320 macro cells organized into 20 logic array blocks (LABs), each containing 16 macro cells. The device supports in-system programmability (ISP) via the JTAG interface, allowing field upgrades without removing the part from the board. Its 10 ns propagation delay and 100 MHz system clock capability make it suitable for high-speed address decoding, DMA arbitration, and peripheral interface logic.
The MAX 9000 architecture uses a 5 V core with 5 V-tolerant I/O, ensuring direct compatibility with legacy TTL and CMOS logic levels. The 208-pin RQFP package provides up to 160 user I/O pins, enabling wide bus interfaces without external multiplexing. Non-volatile EEPROM configuration means the device is operational immediately at power-up, eliminating the configuration PROM required by SRAM-based FPGAs.
Typical applications include industrial control backplanes, telecommunications line cards, test and measurement instrumentation, and legacy system maintenance where the original design must be preserved. The device is widely used as a drop-in replacement in existing MAX 9000 designs and as a bridge between modern processors and legacy peripherals.
When designing with this CPLD, ensure the JTAG chain is properly terminated and that the 5 V supply is well decoupled. Because the part is a mature, non-volatile device, designers should verify availability and consider pin-compatible MAX 9000 variants for long-lifecycle programs.
This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, providing a single reference for engineers maintaining or sourcing MAX 9000 designs.

典型应用
EPM9320RI208-10N 适用于 6 应用s: Industrial Control Backplane Logic, Telecommunications Line Card Glue Logic, Test and Measurement Instrumentation, Legacy System Maintenance and Drop-In Replacement, Bus Bridging and Protocol Conversion, Medical and Diagnostic Equipment Control.
Industrial Control Backplane Logic
The EPM9320RI208-10N fits industrial control backplanes because its 320 macro cells and 160 user I/O pins can implement address decoding, chip-select generation, and bus arbitration for multi-card systems without discrete glue logic. Its 10 ns pin-to-pin delay supports backplane clock rates up to 100 MHz, and the -40C to +85C industrial temperature range matches factory-floor environments. The device is typically placed between the host CPU bus and peripheral card slots, translating 5 V TTL signals and generating wait states. Unlike SRAM-based FPGAs, its EEPROM configuration is live at power-up, so the backplane is operational immediately after power-on with no configuration PROM or boot delay.
推荐
Telecommunications Line Card Glue Logic
In telecommunications line cards, the EPM9320RI208-10N consolidates glue logic for TDM bus interfacing, timeslot assignment, and control-plane register decoding. Its 6,000 usable gates and 320 macro cells replace dozens of 74-series logic packages, reducing board area and improving reliability. The 100 MHz system clock capability supports OC-3 and STM-1 line rates, while the 5 V I/O interfaces directly with legacy telecom backplanes. The device is usually placed between the line interface unit and the system controller, handling interrupt aggregation and status registers. Non-volatile EEPROM configuration ensures the card boots deterministically, which is critical for carrier-grade equipment requiring fast recovery after power interruption.
推荐
Test and Measurement Instrumentation
The EPM9320RI208-10N is well suited to test and measurement instrumentation where deterministic timing and wide I/O count are essential. Its 10 ns propagation delay and 100 MHz clock support trigger generation, pattern sequencing, and high-speed data acquisition control. The 160 user I/O pins allow direct connection to multiple instrument buses without external multiplexers, and the 5 V interface matches legacy GPIB and parallel instrument ports. The CPLD typically implements the trigger state machine and address decoder between the acquisition front end and the host processor. Because configuration is non-volatile, the instrument is ready to measure immediately at power-up, avoiding the boot latency of SRAM-based programmable logic.
推荐
Legacy System Maintenance and Drop-In Replacement
The EPM9320RI208-10N is frequently used to maintain legacy systems where the original MAX 9000 design must be preserved without PCB redesign. Its 208-pin RQFP footprint and 5 V operation match earlier MAX 9000 devices, allowing direct replacement on existing boards. The 320 macro cells and 10 ns timing reproduce original logic behavior, so firmware and JEDEC programming files remain valid. Engineers typically use it to replace failed or obsolete units in industrial, medical, and aerospace equipment where requalification costs are prohibitive. Because the device is non-volatile, no configuration memory is needed, simplifying spares management. Verify the exact speed grade and temperature suffix before ordering to ensure pin and timing compatibility.
推荐
Bus Bridging and Protocol Conversion
The EPM9320RI208-10N implements bus bridging between dissimilar interfaces such as ISA, PCI, and custom backplanes. Its 160 user I/O pins and 320 macro cells can hold address translation tables, handshake state machines, and FIFO control logic in a single device. The 10 ns pin-to-pin delay supports bus cycles in the 50-100 MHz range, and the 5 V I/O is directly compatible with legacy bus signaling. The CPLD is placed between the two bus connectors, converting protocols and generating wait states. Non-volatile configuration means the bridge is active at power-up, which is important for systems that must enumerate devices before the host OS loads. This reduces component count versus discrete transceiver and PAL implementations.
推荐
Medical and Diagnostic Equipment Control
The EPM9320RI208-10N is used in medical and diagnostic equipment for deterministic control of acquisition timing, motor sequencing, and safety interlocks. Its 10 ns propagation delay ensures precise trigger timing, while the 320 macro cells implement redundant state machines and watchdog logic. The industrial temperature range supports equipment operating in non-climate-controlled environments, and the 5 V I/O interfaces with legacy sensor and actuator electronics. The device typically sits between the main controller and the analog front end, generating sample clocks and gating data conversion. Non-volatile EEPROM configuration guarantees the safety logic is active immediately at power-up, a requirement for many medical device certifications.

设计说明
Decouple every VCCINT and VCCIO pin with a 0.1 uF ceramic capacitor placed within 5 mm of the pin, plus a 10 uF bulk capacitor per supply rail. The MAX 9000 family draws transient current during macro cell switching; inadequate decoupling causes ground bounce and unreliable JTAG configuration. Estimated: at 100 MHz with 50% macro cell toggle, dynamic current can reach several hundred milliamps, so size the bulk capacitor for at least 10x the expected transient charge.
Route the JTAG chain (TDI, TDO, TMS, TCK) as short, matched traces with a solid ground return. Keep TCK away from high-speed I/O to avoid clock injection into the configuration logic. Terminate TDO with a series resistor if the trace exceeds 50 mm. The 208-pin RQFP package requires a thermal pad soldered to a ground plane for mechanical and thermal stability.
Do not leave unused I/O pins floating; configure them as inputs with internal pull-ups or tie them to VCCIO through a resistor. Floating inputs on MAX 9000 devices can cause excessive supply current and erratic behavior. Also verify the speed grade suffix (-10 vs -15 vs -20) before ordering, because a slower grade may not meet the original design's timing closure.
