EPM9560RC208-14 Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like logic blocks on a single chip with a central interconnect matrix. In the system hierarchy, the EPM9560 sits between simple SPLDs (like classic PAL/GAL) and larger FPGAs, providing fast deterministic pin-to-pin timing, instant-on behavior (no boot PROM required), and high fan-in / fan-out glue-logic capability. The MAX 9000 family extends MAX 7000 architecture with larger Logic Array Blocks (LABs), more I/O pins, and enhanced in-system programmability (ISP) via JTAG.
Key features of the EPM9560RC208-14 include 560 macrocells distributed across 16 Logic Array Blocks, 149 user I/O pins, 12,000 usable gates, and a maximum operating frequency up to 117.6 MHz. It supports 5 V and 3.3 V mixed-voltage operation on its I/O banks and is in-system programmable through the IEEE 1149.1 JTAG boundary-scan port. The -14 speed grade provides a 14 ns pin-to-pin propagation delay and a 118 MHz internal counter frequency.
The device is implemented in 0.35 µm CMOS EEPROM technology with five programmable logic blocks (the MAX 9000 also adds I/O blocks for each pin), allowing design changes via the Altera MAX+PLUS II or Quartus development flows. The 208-pin RQFP package exposes dedicated JTAG, configuration, and global clock pins for design flexibility. Built-in EEPROM cells retain the design without external boot memory.
Typical applications include high-density glue logic in telecommunications line cards, industrial control boards, ASIC prototyping, peripheral bus interfacing (PCI bridge logic, address decoding, bus arbitration), and replacement of multiple discrete PAL/GAL devices. The fast pin-to-pin delay also suits decoder and interrupt-controller designs where deterministic timing matters.
Designers should plan for a 5 V core supply with local 0.1 µF + 10 µF decoupling near the device. The MAX 9000 architecture allows multiple MAX 9560 devices to be cascaded through the JTAG chain, supporting multi-device ISP flows. Note that newer Altera MAX V / MAX 10 CPLDs have superseded this part - the EPM9560 is generally used today for legacy design maintenance.

Applications typiques
EPM9560RC208-14 convient pour 6 applications: High-Density Glue Logic in Telecommunications, ASIC Prototyping and Logic Emulation, Bus Interface and Address Decoding, Industrial Control and Automation, Legacy Peripheral Bridge and Bus Converter, Test and Measurement Instrument Logic.
High-Density Glue Logic in Telecommunications
The EPM9560RC208-14's 560 macrocells, 149 user I/O pins, and 14 ns pin-to-pin delay make it well suited to telecom line-card glue logic where dozens of small PAL/GAL functions are consolidated onto a single non-volatile device. The 5 V core with mixed 3.3 V/5 V I/O allows direct interfacing to legacy 5 V bus transceivers and modern 3.3 V ASICs without external level shifters. The JTAG (IEEE 1149.1) in-system programmability enables field updates without removing the board, while EEPROM non-volatility guarantees instant-on operation on power-up - critical for telecom systems requiring deterministic cold-start timing. Designers can replace 10-20 discrete 22V10/PALCE610-style devices with one EPM9560, simplifying the BOM and improving testability.
Recommandé
ASIC Prototyping and Logic Emulation
With 12,000 usable gates and 560 macrocells, the EPM9560RC208-14 provides enough capacity to prototype ASICs in the 5K-10K gate range across multiple packages on a single PCB. The 14 ns pin-to-pin delay offers accurate emulation of typical ASIC cell delays, while the deterministic timing model (unlike FPGA look-up-table delays) lets engineers validate timing closure before committing to silicon. The JTAG interface enables fast design iterations: a new netlist can be programmed in seconds via BitBlaster or JTAG cable, dramatically shortening prototype turnaround. The 208-pin RQFP package exposes enough I/O to wire the CPLD into the target board's address, data, and control buses during prototyping. Multiple EPM9560 devices can be cascaded through the JTAG chain for multi-chip prototyping flows.
Recommandé
Bus Interface and Address Decoding
The EPM9560RC208-14's wide I/O count (149 pins) and 14 ns propagation delay make it ideal for multi-bus address decoding, chip-select generation, and interrupt arbitration in PCI, VME, ISA, and proprietary backplane designs. Its deterministic pin-to-pin delay simplifies worst-case timing analysis for setup/hold margins on synchronous buses, while the 5 V/3.3 V mixed I/O allows direct drive of 5 V peripherals alongside 3.3 V host processors. The EEPROM-backed configuration boots instantly at power-on, eliminating the boot PROM typically required by SRAM-based FPGAs. Designers commonly use the EPM9560 to consolidate scattered 22V10 / 16V8 / 20V8 glue-logic devices into a single part, freeing PCB area and reducing the BOM count on legacy backplane cards.
Recommandé
Industrial Control and Automation
The EPM9560RC208-14's 5 V tolerance, robust EEPROM non-volatile configuration, and industrial temperature variants make it well suited for PLCs, motor controllers, and factory-automation controllers where field reliability matters more than cutting-edge speed. Its 560 macrocells can implement complex state machines for sequencing I/O, encoder counters, and safety interlocks in a single chip, while the JTAG port supports field diagnostics and in-system firmware updates without removing the controller from the line. The RQFP-208 package's through-hole-friendly footprint (hand-solderable leads) supports low-volume industrial production runs. The part's deterministic timing also benefits IEC 61131-style PLC scan-cycle scheduling where predictable logic execution is required.
Recommandé
Legacy Peripheral Bridge and Bus Converter
Designers bridging legacy peripherals (ISA, VME, PC/104) to modern processors commonly use the EPM9560RC208-14 as a bus-format translator: its 149 I/O pins and 560 macrocells can implement both bus-side state machines simultaneously, while the 14 ns delay is fast enough to keep up with 33 MHz ISA bus cycles. The 5 V I/O tolerance allows direct connection to legacy 5 V peripherals without buffering, and the JTAG port enables late-stage firmware fixes during the bring-up phase. EEPROM configuration eliminates the boot PROM that would otherwise complicate the bridge card's BOM. The 208-pin RQFP package provides enough margin to expose dedicated diagnostic LEDs and test points on the bridge card.
Recommandé
Test and Measurement Instrument Logic
The EPM9560RC208-14's non-volatile instant-on behavior, mixed-voltage I/O, and deterministic timing suit bench-top and rack-mount test instruments such as logic analyzers, protocol analyzers, and switch-matrix controllers. The 560 macrocells can implement parallel stimulus generators, protocol-state machines, and trigger sequencers in a single chip, while the JTAG boundary-scan chain simplifies board-level interconnect testing during manufacturing. The 5 V I/O banks tolerate direct connection to legacy 5 V measurement front-ends, and the 14 ns delay supports timing generation at frequencies up to ~70 MHz in real-world designs. The part's long-term availability through independent brokers keeps legacy instruments serviceable decades after their original production run.

Principaux différenciateurs
- Highest non-military speed grade in RQFP-208 package (vs EPM9560RC208-15)
- Commercial temperature grade with full JTAG ISP support (vs EPM9560ARC208-10)
- Standard JTAG boundary-scan for in-system programming (vs EPM7256SQC208-10)
Notes de conception
The EPM9560RC208-14 requires a stable 5 V ±5% supply on VCCINT (pin 162 and additional VCC pins). Place 0.1 µF ceramic decoupling capacitors adjacent to every VCC/GND pair on the package perimeter (every 3-5 pins). Add a bulk 10-47 µF tantalum or aluminum electrolytic capacitor at the board's power entry to suppress switching transients from upstream regulators. The I/O banks can be powered at 3.3 V independently of the 5 V core, allowing mixed-voltage interfacing without external level shifters - verify bank voltage compatibility in the MAX 9000 datasheet before mixing 5 V and 3.3 V peripherals.
The EPM9560 uses Altera's MAX+PLUS II (legacy) or Quartus Prime (newer) design flow - confirm tool version compatibility for the -14 speed grade before starting the design. JTAG programming requires the four dedicated pins (TCK, TMS, TDI, TDO at pins 159-164) to be accessible on the PCB for in-system programming; do not tie any of these pins to ground or VCC. The 208-pin RQFP package has gull-wing leads with 0.5 mm pitch - hand-soldering is feasible but reflow is preferred for production. EEPROM programming cycles are limited (~100 erase/program cycles); design firmware-update flows to minimize unnecessary reprogramming.
Route JTAG signals (TCK, TMS, TDI, TDO) as a short daisy-chain with proper pull-ups on TCK/TMS as required by IEEE 1149.1. Keep global clock pins (GCLK1 at pin 143, GCLK2 at pin 144) routed with controlled impedance and short trace lengths to maintain signal integrity across the 5 V core. For mixed-voltage designs, group 3.3 V I/O into one bank and 5 V I/O into another bank to simplify power routing. Place the EPM9560 close to the devices it interfaces with (memory, ASICs, microprocessors) to minimize propagation delay in critical timing paths.
