Typical Applications
EPM9320RC208-15 is suitable for 6 applications: Legacy Industrial Control Boards, Telecommunications Line Cards, Bus Bridging (PCI, VME, ISA), Glue Logic Consolidation, Sustaining Existing 5V Designs, Test and Measurement Instrumentation.
Legacy Industrial Control Boards
The EPM9320RC208-15 fits legacy industrial control boards because its 320 macro cells and 6,000 usable gates consolidate discrete 74-series glue logic into a single 5.0 V EEPROM-based CPLD. Its 15 ns pin-to-pin delay supports deterministic state-machine and address-decoding logic at clock rates up to 117.6 MHz, while non-volatile EEPROM configuration means the device is instant-on with no external configuration PROM. Placed between the host processor bus and peripheral I/O, it implements chip-select decoding and handshake logic. The trade-off is that the 5.0 V core is not 3.3 V tolerant on all pins, so level shifting is required when interfacing modern 3.3 V peripherals.
Recommended
Telecommunications Line Cards
The EPM9320RC208-15 suits telecommunications line cards where wide bus interfacing and deterministic timing are required. Its 208-pin RQFP package provides a high I/O count for interfacing TDM buses and control-plane signals, and the 15 ns propagation delay supports the timing budgets of legacy telecom backplanes. The EEPROM-based MAX 9000 architecture provides instant-on operation, which is important for line cards that must be ready immediately after power-up without a configuration boot cycle. The device implements bus arbitration, clock multiplexing, and status-register logic. Because it is a 5.0 V part, designers must confirm compatibility with mixed-voltage backplanes and add level shifters where 3.3 V signaling is used.
Recommended
Bus Bridging (PCI, VME, ISA)
The EPM9320RC208-15 is well suited to bus-bridging applications such as PCI, VME, and ISA interfaces because its 320 macro cells can implement protocol translation and wait-state generation in a single device. The 15 ns pin-to-pin delay provides adequate margin for 33 MHz PCI and legacy VME timing, and the 208-pin RQFP package supplies enough I/O to route a full address/data bus plus control signals. EEPROM configuration allows the bridge logic to be reprogrammed in-system via JTAG during board bring-up, accelerating debug. The main design consideration is that the 5.0 V supply and I/O levels must be reconciled with 3.3 V PCI signaling, typically requiring bus transceivers or level shifters on the 3.3 V side.
Recommended
Glue Logic Consolidation
The EPM9320RC208-15 is used to consolidate dozens of discrete 74-series logic devices into one programmable part, reducing board area, power, and BOM count. With 6,000 usable gates and 320 macro cells, it absorbs address decoders, multiplexers, counters, and state machines that would otherwise require multiple packages. The 15 ns speed grade supports clock rates up to 117.6 MHz, sufficient for most glue-logic functions, and the EEPROM configuration eliminates the external configuration memory needed by SRAM FPGAs. The trade-off is higher unit cost than discrete logic at very low volumes, so consolidation pays off mainly in medium-to-high volume or space-constrained designs. In-system programmability via IEEE Std. 1149.1 JTAG simplifies field updates.

Sustaining Existing 5V Designs
The EPM9320RC208-15 is primarily sourced today to sustain existing 5.0 V designs that cannot be redesigned. Because Altera declared the device obsolete in 2007 per PDN0706, engineers maintaining legacy equipment rely on remaining distributor and broker stock to keep production lines running. The device's EEPROM-based MAX 9000 architecture and 208-pin RQFP footprint match the original design, so no PCB or firmware changes are required. The key consideration is supply-chain risk: independent-channel stock must be verified for authenticity and date code, and a long-term migration plan to the MAX V family should be developed. Drop-in family variants such as the EPM9320ARC208-15 extend the available supply pool.
Recommended
Test and Measurement Instrumentation
The EPM9320RC208-15 fits test and measurement instrumentation where deterministic, non-volatile logic is needed for trigger generation, timing control, and interface sequencing. Its 15 ns pin-to-pin delay provides repeatable timing for trigger and gate logic, and the EEPROM configuration ensures the instrument boots into a known state without a configuration load cycle. The 208-pin RQFP package offers enough I/O for front-panel control, GPIB or parallel interfaces, and internal bus management. Because the device is 5.0 V, it interfaces naturally with legacy instrument backplanes. Designers should account for the obsolete status by qualifying alternate family variants and securing adequate stock for the instrument's production lifetime.

Key Differentiators
- Non-volatile EEPROM configuration (vs EPM570M256C5N)
- Drop-in family variants extend supply (vs EPM9320ARC208-15)
- Speed-grade flexibility within the same footprint (vs EPM9320RC208-10)
Design Notes
The EPM9320RC208-15 is a 5.0 V core device and requires a well-regulated 5 V rail. Decouple each VCC pin with a 0.1 uF ceramic capacitor placed as close to the pin as possible, plus a bulk 10 uF capacitor per device. Because the part is EEPROM-based, it draws no configuration inrush current at power-up, but the 5 V rail must still ramp monotonically to avoid undefined logic states. Do not power the device from a 3.3 V rail - the MAX 9000 family is not specified for 3.3 V operation.
The 208-pin RQFP package has an exposed thermal pad that must be soldered to a matching copper land and connected to ground with multiple vias for thermal and electrical integrity. Route high-speed clock and bus signals on controlled-impedance traces and keep them away from the JTAG TCK/TMS lines to avoid coupling. Place the JTAG header close to the device and keep TCK, TMS, TDI, and TDO traces short and matched. Follow the manufacturer's RQFP land-pattern drawing for pad dimensions and solder-mask openings.
The most common pitfall is assuming 3.3 V I/O compatibility: the EPM9320RC208-15 is a 5.0 V device and its I/O levels are not 3.3 V tolerant on all pins, so level shifters or bus transceivers are required when interfacing 3.3 V logic. A second pitfall is sourcing: the device was declared obsolete in 2007 per PDN0706, so independent-channel stock must be verified for authenticity and date code. Always program and functionally test incoming parts before committing them to production.
