Typical Applications
EPM9320ARI208-10 is suitable for 6 applications: PCI Bus Interface Logic, Industrial Control Glue Logic, Telecommunications Line Cards, Legacy System Replacement and Repair, Address Decoding and Memory Control, Test and Measurement Instrumentation.
PCI Bus Interface Logic
The EPM9320ARI208-10 is fully compliant with the PCI Local Bus Specification Revision 2.2, making it a natural fit for PCI target and master interface logic in legacy computing and industrial platforms. Its 132 user I/O pins accommodate the 32-bit address/data multiplexed bus plus control signals, while the 10 ns pin-to-pin delay meets PCI timing requirements at 33 MHz. The 5 V core allows direct connection to the PCI bus without external level shifters, reducing component count. Designers typically implement bus arbitration, configuration space registers, and target state machines in the 320 macrocells. The trade-off is power: at 5 V, dynamic power is higher than modern 3.3 V CPLDs, so thermal management via the exposed pad is important in densely packed boards.
Recommended
Industrial Control Glue Logic
In industrial control systems, the EPM9320ARI208-10 consolidates discrete 74-series glue logic into a single non-volatile CPLD, reducing board area and improving reliability. Its -40 C to +85 C industrial temperature rating suits factory automation, motor control, and process instrumentation environments. The 320 macrocells and 6,000 gates can implement address decoding, chip-select generation, wait-state logic, and custom state machines for microcontroller peripherals. Because configuration is stored in EEPROM, the device is instant-on at power-up with no external configuration PROM, which is critical for safety-related industrial equipment that must not have a configuration delay. The 132 I/O pins support wide parallel buses typical of industrial backplanes.
Recommended
Telecommunications Line Cards
Telecommunications line cards often require programmable logic for protocol handling, timeslot interchange, and bus bridging. The EPM9320ARI208-10 provides 320 macrocells and 132 I/O pins, enough to implement TDM framing, HDLC controllers, and PCM highway interfaces in legacy telecom equipment. Its 144.9 MHz counter frequency supports high-speed timing generation, while the non-volatile EEPROM configuration ensures deterministic startup in always-on telecom racks. The industrial temperature range covers central office and remote cabinet deployments. Designers should note that the 5 V core requires level shifting when interfacing with 3.3 V backplanes, and that the exposed-pad RQFP package needs a thermal land for continuous operation.
Recommended
Legacy System Replacement and Repair
Because the EPM9320ARI208-10 is obsolete, a major application is sustaining existing legacy systems where the device must be replaced during repair or refurbishment. The 208-pin RQFP footprint and 320-macrocell architecture match the original MAX 9000 design, so a replacement part can be dropped into an existing socket without PCB changes. Engineers maintaining industrial PCs, medical imaging systems, and military/aerospace equipment rely on the industrial temperature rating and EEPROM non-volatility to preserve original system behavior. When sourcing, verify date codes and authenticity because obsolete parts are frequently counterfeited. Where long-term supply is a concern, migrating the logic to a MAX 10 or MAX V CPLD with a level shifter is the recommended path.
Recommended
Address Decoding and Memory Control
The EPM9320ARI208-10 is well suited to address decoding and memory control in embedded systems with wide address buses. Its 132 I/O pins can capture a 32-bit address bus plus control strobes, and the 10 ns pin-to-pin delay provides fast chip-select generation for SRAM, Flash, and peripheral devices. The 320 macrocells allow implementation of programmable wait-state generators, bank switching, and DMA arbitration logic. Because the device is in-system programmable via IEEE Std. 1149.1 JTAG, address maps can be updated in the field without removing the part. The 5 V core matches legacy 5 V microcontrollers and memory devices, simplifying mixed-signal board design in industrial and instrumentation platforms.
Recommended
Test and Measurement Instrumentation
Test and measurement instruments frequently require custom digital logic for triggering, timestamping, and data acquisition control. The EPM9320ARI208-10 offers 320 macrocells and 144.9 MHz counter frequency, enabling precise event timing and multi-channel trigger logic. Its non-volatile EEPROM configuration means the instrument boots immediately with the correct logic, an important attribute for benchtop equipment. The industrial temperature range supports operation in non-climate-controlled test environments. Designers can implement custom serial protocols, FIFO control, and bus interfaces in a single device, reducing board complexity. The exposed-pad RQFP package provides adequate thermal performance for continuous instrument operation, though forced-air cooling may be needed in high-density chassis.

Key Differentiators
- Industrial temperature rating (vs EPM9320ARC208-10N)
- Fastest speed grade in the 208-pin MAX 9000 family (vs EPM9320ARC208-15)
- Non-volatile EEPROM configuration (vs SRAM-based FPGAs)
- PCI Local Bus Specification Rev 2.2 compliance (vs General-purpose CPLDs)
Design Notes
The EPM9320ARI208-10 uses a 5 V core and I/O, so dynamic power is significantly higher than modern 3.3 V or 1.8 V CPLDs. Estimated: at 144.9 MHz with 50% of macrocells toggling, supply current can reach several hundred milliamps, so decouple each VCC pin with a 0.1 uF ceramic capacitor and add bulk capacitance (10 uF to 100 uF) near the device. Use a dedicated power plane for VCC to minimize IR drop and noise coupling into the PCI or address buses.
The 208-pin RQFP package includes an exposed thermal pad that must be soldered to a matching copper land on the PCB. Estimated: with a typical theta_JA of 25-30 C/W for the exposed-pad RQFP, a 1 W dissipation raises junction temperature by 25-30 C above ambient. In a 70 C industrial ambient, this approaches the 85 C limit, so provide a thermal land of at least 1 square inch with thermal vias to an internal ground plane. Forced airflow is recommended in high-density enclosures.
Because the EPM9320ARI208-10 is obsolete, counterfeit and re-marked parts are common in the independent distribution channel. Always purchase from authorized distributors or verified independent stockists, and inspect date codes and packaging. Additionally, the 5 V I/O does not directly interface with 3.3 V logic; use level shifters or series resistors with clamping diodes. Finally, the EEPROM configuration is non-volatile but has a finite reprogramming endurance, so avoid excessive in-system reprogramming cycles in production.
Route the JTAG signals (TCK, TMS, TDI, TDO) as short, matched traces with a solid ground reference to ensure reliable in-system programming. Keep the TCK trace away from high-speed PCI or clock signals to avoid crosstalk that can corrupt configuration. Place the JTAG header close to the device and include a 10 kOhm pull-up on TMS and a pull-down on TCK as recommended in the MAX 9000 family datasheet.
