EPM9320RC208-20 Ringkasan

The Altera EPM9320RC208-20 is a 320-macrocell, 132-I/O CMOS EEPROM-based Complex Programmable Logic Device (CPLD) from the MAX 9000 family, housed in a 208-pin RQFP (exposed-pad BFQFP) package. Built on Altera's third-generation Multiple Array Matrix (MAX) architecture, it delivers a maximum pin-to-pin propagation delay (tPD) of 20 ns at 5.0 V and integrates approximately 6,000 usable gates with in-system programmability (ISP) via the built-in IEEE Std. 1149.1 JTAG interface. The -20 suffix denotes the 20 ns commercial speed grade.

A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL-like macrocell blocks with a programmable interconnect matrix, sitting in the programmable logic hierarchy between simple SPLDs/GALs and higher-density FPGAs. CPLDs are favored for glue-logic, bus-interface, state-machine, and power-on control tasks where deterministic timing, fast input-to-output response, and instant-on (zero-config-time) operation are required. The MAX 9000 family extends this concept to higher densities than earlier MAX 5000/7000 generations while retaining the predictable timing that makes CPLDs the preferred choice for asynchronous logic replacement.

Key features of the EPM9320RC208-20 include 320 macrocells organized across 20 logic array blocks (LABs), 132 user I/O pins, 5.0 V in-system programmability through the JTAG-compliant IEEE 1149.1 boundary-scan interface, and a commercial 0 °C to 70 °C operating-temperature range. The exposed-pad RQFP-208 package provides a thermal path for moderate dissipation in surface-mount designs, and the EEPROM process allows unlimited reprogramming cycles without an external configuration memory. The device operates from a single 4.75 V to 5.25 V supply, simplifying integration into legacy 5 V logic systems.

Architecturally, the MAX 9000 device combines high-density AND-OR PLA-style logic with fast, deterministic interconnect, giving every macrocell a fixed, predictable delay independent of the design's routing complexity. This contrasts sharply with SRAM-based FPGAs, whose interconnect delays vary with placement. The 132 available I/O pins are 5 V-tolerant within the supply range, supporting TTL and CMOS interfacing without level shifters, and each pin is JTAG-controlled for boundary-scan testability.

Typical applications for the EPM9320RC208-20 include 5 V glue-logic consolidation in industrial controllers, address decoding and bus-interface bridging in legacy microprocessor systems, peripheral control logic in telecommunications and networking equipment, and state-machine replacement in instrumentation. Its instant-on non-volatile behavior makes it especially suitable for safety-critical boot logic that must be valid before any host processor runs.

When designing with this part, observe the 4.75 V to 5.25 V supply window and keep all inputs within the absolute maximum ratings specified in the datasheet; the exposed thermal pad must be soldered to a sufficient copper area to keep junction temperature within the commercial 0 °C to 70 °C range. Use Altera's MAX+PLUS II or Quartus II legacy support tools to fit designs, and verify JTAG chain order when multiple devices share the same boundary-scan port.
