Typical Applications
EPM9320ARI208-10N is suitable for 6 applications: Industrial Automation Glue Logic, Telecommunications Bus Arbitration, Address Decoding and Chip-Select Generation, Legacy PCI Bridge and Expansion Logic, Military and Aerospace Avionics, Consumer Electronics Interface Bridging.
Industrial Automation Glue Logic
The EPM9320ARI208-10N is widely deployed in industrial automation controllers as glue logic that bridges microprocessors to legacy peripherals. With 320 macrocells and 20 LABs, it can replace multiple discrete TTL/CMOS logic chips (74-series gates, latches, decoders) on a single device, reducing board area and BOM cost. The 10 ns tPD and 144.9 MHz fMAX are sufficient to decode ISA-bus addresses, generate chip-select signals, and arbitrate interrupts without introducing timing bottlenecks. The industrial -40C to +85C temperature rating covers factory-floor environments, and the non-volatile EEPROM configuration ensures instant-on behavior after power cycling - critical for deterministic controller startup in PLC and CNC machinery.
Recommended
Telecommunications Bus Arbitration
In legacy telecom line-card and central-office designs, the EPM9320ARI208-10N serves as a bus arbiter and protocol bridge. Its 320 macrocells can implement multi-master PCI-to-ISA bridges, HDLC framing controllers, and T1/E1 line-interface glue logic at line rates up to T1 (1.544 MHz) and E1 (2.048 MHz) easily within timing margins. The 5V-tolerant I/Os match legacy TTL bus levels without level shifters, while the IEEE 1149.1 JTAG interface allows field-reprogrammability for protocol updates and bug fixes. The 208-RQFP package provides high pin density suitable for the bus-oriented pinout typical of telecom backplane interfaces.
Recommended
Address Decoding and Chip-Select Generation
The EPM9320ARI208-10N excels at microprocessor address decoding and chip-select generation, a classic CPLD application where its deterministic timing and high pin count deliver major board-simplification benefits. With 16 dedicated global inputs and 320 macrocells, the device can decode wide address buses (24-32 bits) and generate 20+ chip-select signals for memory banks and peripherals with sub-10 ns latency - matching the access-time requirements of fast SRAM and DRAM chips. The non-volatile configuration means the decoder logic is active at power-on without boot delay, enabling instant memory access by the host CPU on cold-start.
Recommended
Legacy PCI Bridge and Expansion Logic
For legacy PCI bus add-in cards and embedded PCI expansion designs, the EPM9320ARI208-10N provides the configuration-space registers, address decoding, and interrupt routing required to bridge PCI to local buses. Its 5V tolerance matches the original PCI 5V signaling environment (the part predates 3.3V PCI), and its 144.9 MHz fMAX supports 33 MHz PCI clocking with comfortable timing margin for state-machine-based transaction handling. The 320 macrocells are sufficient for full PCI target or master implementations including parity generation and bus mastering arbitration.
Recommended
Military and Aerospace Avionics
The EPM9320ARI208-10N's industrial temperature range (-40C to +85C) and non-volatile EEPROM configuration make it a candidate for military and aerospace subsystems where deterministic instant-on behavior and tolerance to thermal extremes are required. Legacy avionics systems, radar signal processors, and flight-control peripherals have historically relied on the MAX 9000 family for bus-bridging logic between proprietary backplanes and standard microprocessors. The JTAG-based in-system programmability supports field-update scenarios for deployed equipment, and the 208-RQFP package is compatible with high-reliability PCB manufacturing processes used in aerospace electronics.
Recommended
Consumer Electronics Interface Bridging
In consumer audio/video equipment of the late 1990s and 2000s, the EPM9320ARI208-10N bridged proprietary ASIC chipsets to standardized interfaces such as I2C, SPI, UART, and parallel LCD buses. Its 320 macrocells could simultaneously drive an LCD panel controller, manage button-matrix debouncing, and implement power-sequencing logic for multi-rail consumer products. The 5V-tolerant I/Os simplified interfacing with legacy microcontrollers and signal sources, while the 10 ns tPD met the timing requirements of parallel data buses connecting to graphics controllers and memory chips.

Key Differentiators
- Highest-density MAX 9000 CPLD in industrial temperature grade (vs EPM9320ARC208-10N)
- Standard -10 speed grade (10 ns tPD) balances speed and power (vs EPM9320RI208-20)
- Lead-free (Pb-free) "N" finish for RoHS compliance (vs EPM9320ARI208-10)
Design Notes
The EPM9320ARI208-10N was discontinued per Altera PDN0711 in November 2008. Engineers designing new products should select a current-generation CPLD such as Altera/Intel MAX V (5V-tolerant, pin-compatible with MAX 7000) or a Lattice Semiconductor ispMACH 4000ZE series part with verified 208-pin footprint compatibility. For legacy board repairs, source from franchised distributors holding last-time-buy inventory and qualify multiple second-source suppliers to mitigate single-point supply risk.
The 208-pin RQFP (S-PQFP-G208) package has 0.5 mm pitch leads with a 28x28 mm body. Allocate at least 2.5 mm of board real estate beyond the package edges for trace fan-out, and use 0.15 mm/0.20 mm trace-and-space rules on inner layers. A continuous ground plane beneath the package improves thermal dissipation and reduces EMI - the exposed thermal pad (if present on the die flag) should be soldered to a copper pad connected to ground with multiple thermal vias for high-power designs.
Do not apply 3.3V signals to the EPM9320ARI208-10N I/O without level shifting - the device is 5V-tolerant but its inputs will see 3.3V as a logic high and may not meet VIH thresholds across all temperatures. Use proper VCCIO rail decoupling with 0.1 uF ceramic capacitors placed within 5 mm of each VCCIO pin, plus a 10 uF tantalum bulk capacitor on each supply rail. Verify JTAG chain integrity before programming by checking IDCODE values against expected 0x... register contents documented in the MAX 9000 datasheet Boundary-Scan section.
Compliance Information
