EPM9320GC280-20 Présentation
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-like macrocell blocks on a single chip with a programmable interconnect matrix. Positioned in the programmable logic hierarchy between small SPLDs and large FPGAs, CPLDs are widely used for glue logic, bus interfacing, state machines, and boot-time control functions where deterministic propagation delay and instant-on configuration are required. The MAX 9000 family represents Altera's third-generation Multiple Array MatriX (MAX) architecture, which delivers higher density and faster performance than earlier MAX families.
Key features of the EPM9320GC280-20 include 320 macrocells across multiple Logic Array Blocks (LABs), a maximum propagation delay of approximately 23 ns (tpd1), a 100 MHz internal counter frequency, and 5.0-V VCC operation. The device offers built-in JTAG boundary-scan support compliant with IEEE 1149.1, 5.0-V in-system programmability, and pin counts up to 280 in ceramic PGA packaging for high-reliability applications.
Architecturally, the MAX 9000 uses a MultiCore architecture with each macrocell containing a programmable AND/OR array, a flip-flop, and configurable I/O. The non-volatile EEPROM configuration memory provides instant-on behavior at power-up with no external boot PROM required, distinguishing the MAX family from SRAM-based FPGAs. This makes the EPM9320GC280-20 ideal for systems requiring deterministic, microsecond-scale startup.
Typical applications include high-speed controller glue logic, address decoding and bus arbitration in microprocessor systems, telecommunications line-card interface logic, industrial automation controllers, and military/aerospace systems that benefit from the ceramic CPGA package's hermeticity and thermal performance.
When designing with the EPM9320GC280-20, engineers should follow Altera's MAX 9000 datasheet recommendations for decoupling, JTAG chain ordering, and I/O bank grouping. The CPGA package requires a socket or through-hole PCB footprint with adequate thermal relief for high-reliability operating environments.

Applications typiques
EPM9320GC280-20 convient pour 7 applications: High-Speed Bus Glue Logic, Telecommunications Line-Card Interface, Industrial Automation Controllers, Military and Aerospace Systems, Legacy Computing Replacement Boards, Test and Measurement Equipment, Network Router Switching Fabrics.
High-Speed Bus Glue Logic
The EPM9320GC280-20 is well-suited for high-speed bus glue logic between microprocessors, memory, and peripherals because its 320 macrocells and 23 ns tpd (-20 grade) deliver deterministic, single-clock-cycle decoding and arbitration. In a typical PCI or VMEbus interface, the CPLD replaces dozens of 74-series logic chips with address decoding, chip-select generation, and interrupt steering functions. Its non-volatile EEPROM configuration provides instant-on behavior at power-up, avoiding the boot-PROM requirement of SRAM-based FPGAs and ensuring the bus is ready before the host CPU begins its memory fetch sequence.
Recommandé
Telecommunications Line-Card Interface
Telecommunications line cards benefit from the EPM9320GC280-20's high macrocell count and JTAG-based in-system programmability for prototyping multi-protocol interface logic. The device can implement T1/E1 framers, HDLC controllers, and Utopia/Posphy level converters in a single chip, replacing multiple ASICs and reducing BOM cost. The CPGA package's hermetic sealing and wide operating temperature support make the part suitable for outdoor telecommunications cabinets and central-office environments requiring long-term reliability.
Recommandé
Industrial Automation Controllers
Industrial PLC and motor-drive controllers use the EPM9320GC280-20 for deterministic PWM generation, encoder feedback decoding, and safety-logic interlocks. The CPLD's 100 MHz internal frequency supports high-resolution quadrature decoding and stepper-motor pulse streams, while its 23 ns tpd ensures minimum output skew across multiple control channels. The MAX 9000 architecture's EEPROM non-volatility eliminates the need for external boot devices and survives power cycles without reconfiguration - critical for factory-floor equipment that must recover instantly from brownouts.
Recommandé
Military and Aerospace Systems
The EPM9320GC280-20 in ceramic CPGA packaging is qualified for military and aerospace applications where hermeticity, radiation tolerance, and long-term reliability are required. The device is used in avionics bus controllers, missile guidance electronics, and satellite payload interfaces where the non-volatile EEPROM configuration survives single-event upsets that would corrupt SRAM-based FPGA bitstreams. The wide military temperature range and MIL-PRF-38535 screening make the part suitable for flight-proven programs requiring high-confidence programmable logic.
Recommandé
Legacy Computing Replacement Boards
The EPM9320GC280-20 is commonly used to replace aging 74F/74AS TTL glue logic on legacy VMEbus, Multibus, and Q-bus single-board computers where the original discrete-logic design is no longer manufacturable. The 320-macrocell density typically absorbs 15-30 discrete packages into a single CPLD, simplifying the BOM and reducing board rework. The non-volatile EEPROM and 5-V operation match the original TTL power rails, allowing drop-in placement onto existing boards with minimal firmware changes.
Recommandé
Test and Measurement Equipment
Test and measurement instruments use the EPM9320GC280-20 for high-speed pattern generation, timing sequencers, and parallel data-acquisition control. The device's JTAG interface simplifies in-field firmware updates as new test protocols are added, while the deterministic 23 ns tpd supports precise timing-edge generation. The 280-pin CPGA package provides enough I/O to drive 32+ channels of digital stimulus or capture, making it ideal for ATE (Automated Test Equipment) pin-electronics cards and boundary-scan test controllers.
Recommandé
Network Router Switching Fabrics
Network switches and routers use the EPM9320GC280-20 for cell/packet header parsing, queue management, and backplane arbitration where the CPLD's deterministic latency and instant-on configuration are valued over FPGA flexibility. The 320 macrocells support multi-port lookups and TCAM-like pattern matching for L2/L3 forwarding decisions. The 5-V operation tolerates noisy backplane power rails typical of chassis-based telecom equipment, and the JTAG ISP allows field upgrades without removing line cards.

Principaux différenciateurs
- Same-package drop-in with faster speed grade (vs EPM9320GC280-15)
- Ceramic PGA hermeticity for high-reliability applications (vs Plastic PGA / BGA MAX 9000 variants)
- Non-volatile EEPROM instant-on configuration (vs SRAM-based FPGAs (Cyclone, Spartan))
Notes de conception
Estimated: At 100 MHz toggle frequency with 50% I/O utilization (140 of 280 pins active at 20 pF loads), the EPM9320GC280-20 ICC draw typically falls between 250-400 mA from a 5.0-V supply. Place 0.1 µF ceramic decoupling capacitors within 5 mm of every VCC/ground pin pair, plus a single 10 µF bulk tantalum or ceramic capacitor near the PGA socket body. The CPGA package's vertical lead inductance benefits from multi-point VCC distribution; do not rely on a single VCC pin.
The 280-pin CPGA package requires a through-hole PGA socket (e.g., Augat or Mill-Max 280-pin PGA socket) or a custom PCB footprint with 2.54 mm pitch plated through-holes. Ensure the PCB footprint matches the Altera MAX 9000 datasheet recommended land pattern exactly, including the central thermal pad. Maintain at least 1.5 mm of clearance around the package body for socket retention clips and test-probe access during JTAG programming.
Do not assume any 320-macrocell MAX 9000 part will drop in for the EPM9320GC280-20: only same-package (280-pin CPGA) parts are pin-compatible. Plastic PGA and BGA variants (e.g., EPM9320BC356-15, EPM9320RI208-10) have different pinouts and require PCB redesign. The -20 speed grade is the slowest in the family - migrating to -15 or -10 is a cost-vs-timing trade-off and is fully pin-compatible within the same package. Always re-validate JTAG chain ordering when multiple MAX 9000 devices share the same TCK/TMS bus.
