EPM9320ARC208-10 概述
A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-style macrocell arrays on a single chip with a global interconnect fabric. CPLDs sit in the broader taxonomy: programmable logic -> CPLD/FPGA family -> non-volatile logic. They are valued for deterministic, predictable timing (no configuration load latency), high I/O count, and instant-on operation, making them complementary to SRAM-based FPGAs in glue-logic, bus-interface, and power-up sequencing roles.
Key features of the EPM9320ARC208-10 include programmable speed/power optimization (each macrocell can run at 50% or less power with only a nominal timing delay), JTAG-based IEEE 1149.1 boundary-scan test support, multi-voltage I/O compatibility, and built-in thermal management for the high-density RQFP package. The MAX 9000 family supports a wide range of package options including PLCC, RQFP, PGA, and BGA, all pin-compatible within a given package class for design flexibility.
The device is fabricated on a 5.0 V CMOS EEPROM process, providing non-volatile storage of the logic configuration. The 320-macrocell array with 16 LABs (Logic Array Blocks) provides predictable, deterministic timing suitable for state machines, address decoding, and synchronous control logic.
Typical applications include high-speed bus interface bridging, address decoding and chip-select generation, glue logic replacement for ASIC designs, industrial control systems, telecommunications infrastructure, and legacy system upgrades. The 5V tolerance makes it especially useful in industrial and telecom systems still based on 5V logic.
When designing with the EPM9320ARC208-10, perform a complete thermal analysis as recommended in Altera Application Note 74 (Evaluating Power for Altera Devices) before committing the design. The RQFP-208 package's power dissipation capability depends significantly on PCB layout, copper area, and airflow, so adequate thermal relief is essential for reliable high-speed operation.

典型应用
EPM9320ARC208-10 适用于 6 应用s: Bus Interface Bridging and Protocol Conversion, Address Decoding and Chip-Select Generation, Industrial Control and Factory Automation, Legacy System Upgrade and ASIC Replacement, Telecommunications Infrastructure Glue Logic, Test and Measurement Equipment.
Bus Interface Bridging and Protocol Conversion
The EPM9320ARC208-10's 320 macrocells and 10 ns tPD make it ideal for bridging asynchronous processor buses between microcontrollers, DSPs, and ASICs operating at different clock domains. With 144.9 MHz fMAX, the device can reliably resolve addresses and generate chip-selects within a single clock period even at 50 MHz bus speeds, eliminating wait-state insertion. The 208-pin RQFP exposes sufficient I/O for full 32-bit address/data buses plus control signals, while EEPROM-based ISP allows field updates when bus protocols change. Designers typically use MAX+PLUS II or Quartus to compile state machines that convert between protocols such as PCI-to-ISA, VME-to-PCI, or proprietary DSP host ports.
推荐
Address Decoding and Chip-Select Generation
The EPM9320ARC208-10 excels at generating chip-select signals for memory and peripheral banks in microprocessor systems, where its 10 ns tPD keeps decoder latency well below typical memory access times (typically 50-70 ns for SRAM, 100-200 ns for DRAM). Each macrocell can implement a sum-of-products decode term, and 320 macrocells comfortably handle 16-32 chip-select lines with overlapping address windows. The programmable speed/power feature allows non-critical decoders to drop to half-power mode, reducing overall system power. EEPROM storage means the decode map survives power cycles without boot firmware.
推荐
Industrial Control and Factory Automation
Industrial control systems benefit from the EPM9320ARC208-10's deterministic timing, 5V I/O tolerance for legacy sensor/actuator interfaces, and JTAG-based in-system programmability for field upgrades. The 320-macrocell capacity handles multiple PWM generators, encoder counters, and safety interlock logic on a single chip. With the industrial-temp EPM9320ARI208-10 variant, the same design operates from -40C to +85C in factory environments. The non-volatile EEPROM configuration means PLC-style controllers start executing deterministic logic immediately at power-up with no boot PROM, critical for real-time control loops.
推荐
Legacy System Upgrade and ASIC Replacement
The EPM9320ARC208-10 is a proven drop-in replacement for legacy gate arrays and bipolar PROMs in telecommunications, military, and aerospace systems designed in the 1990s and 2000s. Its 5V tolerance and 320-macrocell capacity match the logic density of typical 10K-gate ASICs. The MAX+PLUS II toolchain accepts standard TTL libraries and EDIF netlists, enabling logic re-implementation without redesigning the surrounding analog and power circuits. JTAG-based ISP eliminates the need for socketed UV-EPROM parts in the field, simplifying logistics for long-life-cycle programs.
推荐
Telecommunications Infrastructure Glue Logic
Telecom equipment designers choose the EPM9320ARC208-10 for mid-density glue logic in line cards, baseband processing boards, and backplane controllers. The 10 ns tPD and 144.9 MHz fMAX comfortably handle 77.76 MHz ATM cell-tax logic, E1/T1 framing, and HDLC controllers. The 208-pin RQFP package provides sufficient I/O to interface with multiple ASICs, FPGAs, and network processors without multiplexing. 5V I/O compatibility avoids level-shifters when interfacing with legacy telecom ASICs designed for 5V TTL/CMOS rails.
推荐
Test and Measurement Equipment
Test equipment such as logic analyzers, protocol exercisers, and ATE fixtures benefit from the EPM9320ARC208-10's deterministic timing and reconfigurable architecture. Engineers can implement custom stimulus generators, response comparators, and timing-reference circuits that would be impractical in discrete 74-series logic. The JTAG interface enables rapid pattern reloading between test runs, and the EEPROM storage preserves calibration personality across power cycles. The 208-pin package exposes enough I/O to drive 16-32 channels of stimulus or monitoring simultaneously.

设计说明
Estimated: At 100% utilization (320 macrocells at 144.9 MHz toggle, 5.0 V VCC), the EPM9320ARC208-10 dissipates approximately 1.5-2.5 W. The RQFP-208 package has an integrated heat sink that requires a minimum of 25 cm^2 of PCB copper area beneath the package and 100-200 LFM airflow for reliable operation at maximum frequency. Perform a complete thermal analysis as recommended in Altera Application Note 74 (Evaluating Power for Altera Devices) before committing to high-density designs. Without thermal relief, junction temperature can exceed 125C and trigger intermittent logic faults.
Decoupling is critical for 5V CPLD designs at 144.9 MHz. Place one 0.1 uF ceramic capacitor within 5 mm of each VCC pin (typically 11 VCC pins on the RQFP-208) and a bulk 47-100 uF tantalum or aluminum electrolytic at the board's 5V input. The MAX 9000 datasheet specifies that improper decoupling can cause VCC droop during simultaneous I/O switching, leading to brownout-induced configuration loss. Use a continuous ground plane beneath the device to minimize ground bounce on high-fanout nets.
Common pitfalls when using the EPM9320ARC208-10 include: (1) exceeding 5.0V on any I/O pin (absolute maximum is 7.0V per datasheet, sustained operation at 5.5V stresses EEPROM cells); (2) mixing 3.3V and 5V signals without level-shifters - the MAX 9000 inputs are 5V TTL-compatible but output VOH of 4.4V minimum may not meet 3.3V logic thresholds reliably; (3) forgetting JTAG chain termination if multiple devices share TCK/TMS - install the recommended pull-up on TMS and pull-down on TCK per IEEE 1149.1.
Route JTAG signals (TCK, TMS, TDI, TDO) as a daisy chain with no stubs, keeping total chain length under 15 cm. Per the MAX 9000 datasheet, TCK rise/fall times must remain below 5 ns - use series-damping resistors (22-33 ohm) near the TCK driver if long traces are unavoidable. Place a 10 kohm pull-up on TCK and TMS to keep the JTAG TAP controller in a known state during power-up, preventing accidental JTAG transitions that could reconfigure the device.
