EPF81188ARC240-4AA Ringkasan

The Intel (formerly Altera) EPF81188ARC240-4AA is a member of the FLEX 8000 family of SRAM-based Field-Programmable Gate Arrays (FPGAs) housed in a 240-pin RQFP (Plastic Quad Flat Pack) package. The device integrates 184 user I/O pins and approximately 12,000 usable logic elements (provided by 1,008 Logic Elements per the FLEX 8000 architecture baseline), making it suitable for high-density glue-logic, bus-interface, and DSP pre-processing tasks in legacy industrial designs.

An FPGA (Field-Programmable Gate Array) is a type of programmable logic device that combines the integration density of a gate array with the design flexibility of in-system programmability. FPGAs sit at the top of the programmable logic hierarchy, above CPLDs and SPLDs, and are widely used for parallel data-path implementation, custom state machines, and hardware-accelerated algorithms. The FLEX 8000 family in particular uses a fine-grained Look-Up-Table (LUT) based architecture with continuous FastTrack interconnect, optimized for high I/O count and predictable timing.

Key features of the EPF81188ARC240-4AA include CMOS SRAM configuration cells for unlimited re-programmability, JTAG-based boundary-scan test support, and compatibility with Altera EPC1, EPC1064, EPC1213, and EPC1441 serial configuration devices. The device supports both serial and parallel configuration modes via a dedicated configuration controller, allowing bitstreams to be loaded from EPROM, system memory, or a microprocessor. Internal configuration clocking handles the entire configuration sequence automatically at power-up.

Architecturally, the EPF81188ARC240-4AA is built around Lab/Logic Array Blocks (LABs) interconnected by the FastTrack row/column routing network, providing predictable delay characteristics for synchronous designs. Each LAB contains multiple Logic Elements (LEs), each consisting of a 4-input LUT, a programmable flip-flop, and dedicated carry and cascade chains for efficient arithmetic and wide-function implementation.

Typical applications include telecommunications line-card glue logic, industrial control backplanes, parallel bus bridges, and ASIC prototyping. The 240-RQFP package is preferred for designs that need high I/O count without resorting to fine-pitch BGA assembly, allowing assembly on cost-effective 2-layer through-hole-compatible boards when paired with adapter footprints.

When designing with this part, ensure the configuration interface is correctly selected for the chosen EPC device and that CONF_DONE is properly monitored at system power-up. Be aware that the EPF81188ARC240-4AA has reached end-of-life status from the original manufacturer and is primarily supported via the secondary/aftermarket channel; engineers should plan for long-term component availability risk.
