EPM9560WC208-20 - 560-Macrocell CPLD, 23.6ns, PQFP-208 | Intel/Altera
MPN: EPM9560WC208-20 ✗ انتهى عمره الإنتاجيEPM9560WC208-20 نظرة عامة
A CPLD (Complex Programmable Logic Device) is a non-volatile reconfigurable digital IC built from an array of AND/OR macrocell structures backed by EEPROM or flash memory; it occupies the design hierarchy between simple PLDs (PAL/GAL) and FPGAs, providing deterministic timing, fast I/O response, and instant-on behavior without external boot memory. Within Altera’s MAX 9000 family the EPM9560 sits at the top of the 9000 series density range, with 149 usable I/O pins and a programmable interconnect that makes it well suited to bus decoding, address mapping, glue-logic and state-machine replacement in industrial and telecom systems.
Key features of the EPM9560WC208-20 include 560 macrocells, 35 LABs, 149 user I/O pins, JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan test (BST) interface, dual 3.3 V/5 V I/O capability, and a programmable register/feedback architecture. The “W” suffix designates the power PQFP package with enhanced thermal characteristics for high-density designs, and the “-20” designator indicates a 23.6 ns pin-to-pin logic delay suitable for systems clocked up to roughly 40 MHz on combinational paths.
Architecturally the device uses an EEPROM-based macrocell with individually programmable product-term steering, D/T/JK flip-flops, and a global interconnect matrix that delivers predictable, deterministic timing independent of routing density. This makes timing closure straightforward for address decoding, interrupt steering, and synchronous state-machine designs where FPGAs would add unnecessary silicon cost and configuration overhead.
Typical applications include high-density bus and address decoding in microprocessor/microcontroller systems, peripheral interface glue logic (e.g., PCI/ISA bus bridges), state-machine and sequencer replacement, industrial control logic, telecom backplane glue logic, and JTAG-driven system monitoring. The 149 I/O pins allow large pin-count designs to be consolidated into a single PLD.
When designing with this device, always observe the maximum I/O count (149), respect the dual-voltage VCCIO/VCCINT power sequencing rules, and use the Quartus II or MAX+PLUS II toolchain for design entry, fitting, and JTAG programming. Decoupling caps (0.1 microfarad ceramic in parallel with 10 microfarad bulk) should be placed within 1 cm of each supply pin to maintain signal integrity during in-system programming cycles.

Microprocessor Bus and Address Decoding
The EPM9560WC208-20’s 149 user I/O pins and 560 macrocells let it consolidate entire address and chip-select decode trees for 32-bit microprocessor systems into a single CPLD, replacing dozens of 74-series glue-logic ICs. With 23.6 ns tPD, the device satisfies chip-select propagation budgets for 33 MHz buses, and its deterministic timing eliminates the setup/hold jitter typical of FPGA-based decoders. Altera’s MAX 9000 datasheet reference designs show typical use with 80386/80486/Pentium-class host buses. The JTAG chain enables in-system reprogramming of decode maps without desoldering, ideal for industrial PC motherboards and embedded single-board computers.

Peripheral Interface Glue Logic
The EPM9560WC208-20 serves as a flexible bridge between microcontrollers, memory, and legacy peripherals (ISA bus, PCI, parallel ports, UARTs, FIFOs) where discrete logic would otherwise require many packages. Its 35 LABs and dual 3.3 V/5 V I/O capability let designers mix 5 V peripherals with a 3.3 V processor on the same board without level shifters. Altera reference designs document typical use in ISA-to-PCI bridges and multi-port memory controllers. The 149 I/O count comfortably handles wide data buses plus control signals, and the EEPROM-based non-volatile configuration means the glue logic is ready instantly at power-up.
موصى به
Industrial Control and Sequencer Logic
The EPM9560WC208-20 is widely deployed in industrial PLCs, motor controllers, and machine automation where deterministic state-machine behavior and high noise immunity are mandatory. Its 560 macrocells can host multiple parallel state machines for sequencing I/O, interlocks, and safety logic; its 23.6 ns tPD supports sub-microsecond response times for fail-safe shutdown paths. The JTAG BST (IEEE 1149.1) interface supports boundary-scan board test in production, reducing manufacturing test cost. Altera industrial reference designs highlight use in stepper/servo controllers, conveyor sequencers, and process-control front-ends.
موصى به
Telecom Backplane Glue Logic
The EPM9560WC208-20 is a workhorse in legacy telecom backplanes where it handles line-card interface logic, clock distribution, alarm steering, and HDB3/AMI encode-decode state machines. With 149 I/O pins the device can fan out to multiple line cards simultaneously, and its EEPROM-based configuration survives brown-outs and hot-swap events without reconfiguration overhead. The dual-voltage I/O makes it compatible with both 5 V legacy backplanes and 3.3 V newer ASICs. Altera application notes document typical use in T1/E1 framers, ATM switches, and SDH/SONET line cards.
موصى به
State-Machine and Sequencer Replacement
Designers use the EPM9560WC208-20 to replace discrete MSI/LSI state machines, counters, and sequencers that would otherwise consume 5–10 standard-logic packages. Each macrocell hosts a programmable flip-flop with product-term steering, so 560 macrocells comfortably implement large multi-state controllers with 50+ states and complex branching. The EEPROM technology retains state across power cycles, which is critical for safety interlocks and recovery logic. Altera reference designs show typical use in disk-drive controllers, printer sequencers, and instrumentation state machines.

Legacy Computing Platform Emulation
The EPM9560WC208-20 is used by hardware enthusiasts and industrial-repair channels to recreate or replace obsolete glue-logic on legacy 386/486/Pentium motherboards, VMEbus boards, and STD-bus cards. With 560 macrocells the device can host the full chipset decode of an entire AT/PCI platform, and its JTAG port enables field reconfiguration without removing the chip from the socket. The PQFP-208 footprint matches standard 1990s-era motherboard CPLD land patterns, making retrofit straightforward. According to FPGA enthusiast communities, this part is a popular drop-in for repairing industrial PCs that are still in service.

JTAG-Based System Monitoring and Test
The EPM9560WC208-20’s built-in JTAG BST (boundary-scan test) interface enables board-level interconnect test, cluster-pin diagnostics, and in-field logic reconfiguration without external programmers. Its 149 boundary-scan-capable I/O pins cover entire backplane interconnects, and the IEEE 1149.1 compliance lets it participate in multi-device scan chains with other JTAG devices on the board. Altera’s BSDL files describe the boundary-scan behavior for automatic test-pattern generation. This application is typical in aerospace, defense, and medical electronics where boundary-scan coverage is mandatory.

ملاحظات التصميم
The EPM9560WC208-20 requires separate VCCINT (5 V internal logic) and VCCIO (3.3 V or 5 V I/O) rails. Per Altera MAX 9000 datasheet, place a 0.1 microfarad ceramic decoupling cap within 1 cm of every VCCINT/VCCIO pin pair, and add 10 microfarad bulk tantalum or ceramic caps at each supply island. Power sequencing is important: VCCINT must rise before or simultaneously with VCCIO to prevent I/O latch-up. Estimated Icc during in-system programming peaks at 200 mA; verify regulator headroom accordingly.
The PQFP-208 package has 0.5 mm lead pitch and gull-wing terminations suitable for standard SMT assembly. Use a land pattern that matches JEDEC MS-026 variation BBA. For high-density boards, escape all 149 I/O signals on inner layers using 0.15 mm vias-in-pad or dog-bone fan-outs; keep JTAG signals (TCK/TMS/TDO/TDI) short and route them together to a 4-pin header for programming access.
Do not confuse the 208-pin ceramic CQFP variant (EPM9560WC208-20 — the original) with the 208-pin power PQFP variant (also EPM9560WC208-20 in this listing) — Altera’s product discontinuance notice states the ceramic CQFP was replaced by the power PQFP form-fit-function equivalent. Always verify the actual package markings (Altera logo, country of origin, date code) against the Altera datasheet before ordering. Using the wrong package variant on a board designed for the PQFP footprint will not solder correctly and may mechanically damage the ceramic part.
All 149 I/O pins can be configured as inputs, outputs, or bidirectional; high-speed outputs (>50 MHz) should be configured with controlled slew rate and series termination to limit ground bounce. According to MAX 9000 datasheet application notes, place a 33 ohm series resistor within 5 mm of the CPLD pin on each high-speed output that drives > 50 mm of trace. Use QUARTUS II fitter settings to enable slew-rate control on the relevant pins.
معلومات الامتثال
The EPM9560WC208-20 in the legacy W/PQFP package is non-compliant with RoHS due to lead-bearing termination; choose EPM9560RC208-20x variants (R-suffix) for RoHS-compliant drop-in equivalents. Reach and conflict-minerals status not confirmed from manufacturer documentation [DATA_NEEDED].
