EPM9320ARC208-10 Обзор

The Altera EPM9320ARC208-10 is a high-performance CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 9000 device family, delivering 320 macrocells with a 10 ns pin-to-pin logic delay in a 208-pin RQFP (Power Quad Flat Pack) package. The device integrates 6,000 usable gates and operates from a 5 V supply, offering 144.9 MHz maximum internal performance and in-system programmability (ISP) through the built-in IEEE Std. 1149.1 JTAG interface. The MAX 9000 architecture combines third-generation Multiple Array MatriX (MAX) technology with EEPROM configuration memory for instant-on, non-volatile behavior.

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.

Типичное применение

EPM9320ARC208-10 подходит для 6 применениеs: 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.

🖥️

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.

🏭

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.

✈️

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.

🌐

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.

🔧

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.

What is the pin-to-pin logic delay of EPM9320ARC208-10?
The EPM9320ARC208-10 has a pin-to-pin logic delay (tPD) of 10 ns, as encoded in the part suffix '-10'. According to the MAX 9000 datasheet, this corresponds to a maximum internal operating frequency of 144.9 MHz. This speed grade suits high-speed address decoding, bus arbitration, and state-machine designs requiring deterministic timing.
How many macrocells does the EPM9320ARC208-10 contain?
The EPM9320ARC208-10 contains 320 macrocells organized into 16 Logic Array Blocks (LABs), with approximately 6,000 usable gates. According to Altera MAX 9000 family documentation, this density targets bus-interface bridging, peripheral control, and glue-logic consolidation applications that exceed the capacity of smaller MAX 7000 devices.
What package does the EPM9320ARC208-10 use?
The EPM9320ARC208-10 is packaged in a 208-pin RQFP (Power Quad Flat Pack) with an integral heat sink for thermal dissipation. According to the MAX 9000 datasheet, RQFP is one of four supported package types (PLCC, RQFP, PGA, BGA), and the heat sink is essential for the higher-power density of this 320-macrocell member.
Is EPM9320ARC208-10 in-system programmable?

Choose the 'I' suffix for industrial (-40C to +85C) operating environments, and the 'C' (commercial, 0C to +70C) for benign conditions.
Is EPM9320ARC208-10 still in production?
No, the EPM9320ARC208-10 is in last-time-buy (LTB) lifecycle status as of 2026-09-13. Altera (now Intel PSG / Altera) has discontinued the MAX 9000 family and is shipping remaining inventory. The successor family is MAX II (and MAX V), which offer similar glue-logic density with lower power and active production status.
What is the best drop-in replacement for EPM9320ARC208-10?
The best drop-in replacement for EPM9320ARC208-10 within the MAX 9000 family is the EPM9320ARC208-15 (same package, slower tPD) or EPM9320ARI208-10 (industrial temp, same speed). According to cross-reference data, both share the same 208-pin footprint. For new designs requiring active production, migrate to a MAX II EPM240 or EPM570 CPLD with Quartus Prime support.
Where can I download the EPM9320ARC208-10 datasheet PDF?
The official EPM9320ARC208-10 datasheet is available as the MAX 9000 Device Family datasheet from Altera's documentation archive (altera.com/literature/ds/m9000.pdf). Third-party mirrors (digchips.com, fpgakey.com) also host PDF copies. According to Altera documentation policy, the datasheet remains available for legacy parts even after last-time-buy status.
What is the pinout of EPM9320ARC208-10?
The EPM9320ARC208-10 pinout is documented in the MAX 9000 Device Family datasheet, Chapter 2 (Pin Information). The 208-pin RQFP package provides dedicated JTAG pins (TCK, TMS, TDI, TDO), multiple VCC/GND pairs distributed for noise immunity, and I/O pins organized into banks. Engineers should consult the datasheet pin tables, not the package outline, when designing the PCB land pattern.
What Altera equivalent is pin-compatible with EPM9320ARC208-10?
Pin-compatible Altera equivalents for EPM9320ARC208-10 include the EPM9320ARC208-12, EPM9320ARC208-15, EPM9320ARI208-10 (industrial temp), and EPM9320ARI208-15 - all in the same 208-pin RQFP. According to FindIC cross-reference data, the main differences are speed grade and operating temperature. All four are direct drop-in replacements for the same PCB footprint.
What are the key specifications of EPM9320ARC208-10 engineers should know?
The EPM9320ARC208-10 key specifications are: 320 macrocells, 10 ns tPD, 144.9 MHz fMAX, 6,000 usable gates, 5.0V VCC, EEPROM-based ISP via JTAG (IEEE 1149.1), RQFP-208 package with integral heat sink, and programmable speed/power per macrocell. According to the MAX 9000 datasheet, these parameters position it for high-density 5V glue logic, bus bridging, and synchronous state-machine applications.

Руководство по выбору

Choose the EPM9320ARC208-10 when you need a 320-macrocell CPLD with 10 ns tPD in a 208-pin RQFP for commercial-temperature (0C to +70C) applications. It is ideal for high-speed bus bridging, address decoding, and glue-logic replacement in legacy 5V systems. Choose the EPM9320ARC208-15 if the same density and footprint are needed but 15 ns timing is acceptable - this gives cost savings for non-critical paths. Choose the EPM9320ARI208-10 for industrial (-40C to +85C) deployments requiring identical 10 ns performance. Avoid the EPM9320ALC84-10 unless your design fits within 84 I/O pins - the PLCC package is not drop-in compatible with the RQFP-208 PCB layout. For new designs, consider migrating to a MAX II (EPM240/EPM570) or MAX V CPLD, which offers similar logic density with active lifecycle status and lower power.

Заметки по проектированию

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.
