Typical Applications
EPM9480RC240-20 is suitable for 6 applications: Legacy Glue-Logic Consolidation, Address Decoding and Bus Interface Bridging, Power-Up Sequencing for Multi-Rail Systems, State-Machine and Protocol Controllers, Industrial Control Backplanes, Telecom Equipment Line Cards.
Legacy Glue-Logic Consolidation
The EPM9480RC240-20 is well-suited to consolidating multiple legacy PAL, GAL, and 22V10 devices onto a single non-volatile CPLD in industrial backplane designs. Its 480 macrocells and 175 user I/O pins can absorb 10-20 discrete PLDs in one package, while the deterministic 20 ns tpd guarantees worst-case timing regardless of internal routing. Designers route each legacy PLD function into one of the MAX 9000 Logic Array Blocks and rely on JTAG ISP to reprogram the part without removing it from the board, dramatically reducing BOM count and assembly cost.
Recommended
Address Decoding and Bus Interface Bridging
With 175 user I/O pins and a 20 ns tpd, the EPM9480RC240-20 acts as a fast address decoder or bus bridge between legacy microprocessors and modern peripherals in telecom and industrial systems. The wide input voltage tolerance (3.3 V or 5 V I/O configurable) lets one device straddle mixed-voltage buses without external level shifters. The MAX 9000 architecture's deterministic interconnect delay means the same decode latency is achieved whether the chip routes one macrocell or 480, simplifying timing closure for designers migrating from discrete 74LS/74F logic.
Recommended
Power-Up Sequencing for Multi-Rail Systems
The EPM9480RC240-20's non-volatile EEPROM configuration makes it ideal for power-up sequencing controllers in multi-rail systems where each rail must come up in a specific order to avoid latch-up. At power-on the device is active within microseconds (no FPGA-style configuration time), and its 480 macrocells can generate 20+ independent rail-enable signals with precise inter-rail delay chains. JTAG ISP allows in-field sequencing firmware updates without board removal, which is valuable for telecom equipment that cannot be easily powered down.
Recommended
State-Machine and Protocol Controllers
The EPM9480RC240-20 is well-matched to implementing complex state machines and protocol controllers such as UART, SPI, I2C bridges, or custom industrial protocols. Its 480 macrocells and 676 family-level flip-flops support 30+ parallel state machines, and the deterministic 20 ns tpd simplifies the timing analysis for synchronous protocol bit-banging. The 240-pin RQFP package exposes enough I/O for full-duplex multi-channel designs, and the JTAG ISP interface allows rapid firmware iteration during development.
Recommended
Industrial Control Backplanes
The EPM9480RC240-20's 240-pin RQFP package with 175 user I/O pins makes it a strong fit for industrial backplane controllers that aggregate dozens of digital signals from sensor and actuator cards. Its 4.75 V to 5.25 V supply tolerance matches 5 V backplane rails, while configurable 3.3 V or 5 V I/O signaling lets one CPLD interface both legacy and modern cards. The non-volatile EEPROM configuration provides instant-on behavior critical for safety systems, and JTAG ISP supports field-upgradable control logic in installed equipment.
Recommended
Telecom Equipment Line Cards
The EPM9480RC240-20 is commonly deployed in telecom line cards as a glue-logic hub between framer ICs, network processors, and SERDES devices. Its 480 macrocells absorb TDM/Ethernet overhead processing, while 175 I/O pins handle multi-port T1/E1 or Ethernet aggregation. The MAX 9000 family's deterministic 20 ns timing guarantees consistent latency for voice traffic, and JTAG ISP enables remote firmware updates when integrated with a microcontroller. For new designs, modern MAX V CPLDs are preferred, but the EPM9480 remains a proven choice in installed telecom infrastructure.

- Lower density than EPM9560 but with proven availability (vs EPM9560RC240-20)
- 240-pin RQFP package enables larger user I/O count (vs EPM9480RC208-20 (208-RQFP))
Design Notes
Perform a complete thermal analysis before committing the EPM9480RC240-20 to a design, because the 240-pin RQFP (32x32 mm) package dissipates more heat than the smaller BGA or PLCC variants in the MAX 9000 family. Reference Altera Application Note 74 (Evaluating Power for Altera Devices) for power budgeting. Estimated: at 100% toggle rate on 175 outputs at 5 V and 100 MHz, the device may dissipate 1.5-2.5 W; ensure your PCB thermal design accounts for this. Use thermal vias under the exposed die-attach pad region and provide adequate copper pour on inner PCB layers.
Use a 4-layer PCB with dedicated ground and power planes for the EPM9480RC240-20 to minimize ground bounce on the 175 user I/O pins and to support the IEEE 1149.1 JTAG signal integrity. Decouple VCCINT and VCCIO pins with 0.1 uF ceramic capacitors placed within 5 mm of each power pin, plus bulk 10 uF tantalum capacitors at each power-section entry point. Route JTAG signals (TDI, TDO, TMS, TCK) as a daisy chain with 10 kohm pull-ups on TMS and TCK to keep the TAP controller in a known state during power-up.
Common pitfalls when using the EPM9480RC240-20: (1) Forgetting that the device is NRND and designing it into new production without a migration plan to MAX V or MAX 10; (2) mixing 3.3 V and 5 V signals on the same I/O bank without configuring VCCIO correctly per bank; (3) omitting JTAG pull-up resistors which leaves the TAP controller floating at power-up and can cause unintended IDCODE shifts during reset; (4) using a ByteBlasterMV instead of the original ByteBlaster - MAX 9000 ISP requires 5 V VCC on the programming cable for legacy devices. Always verify programming hardware compatibility before finalizing the BOM.
Compliance Information
