EPF8820AQC160-2 Ringkasan

The Intel (formerly Altera) EPF8820AQC160-2 is a member of the FLEX 8000 family of CMOS SRAM-based programmable logic devices, offering 672 logic elements (cells) and 120 user I/Os in a 160-pin Plastic Quad Flat Pack (PQFP) package. Built on a 0.42 µm CMOS process and rated for a 5 V supply, it delivers up to 8,000 usable gates with a maximum toggle frequency of 125 MHz, making it suitable for glue-logic, bus-interface, and medium-complexity state-machine designs in commercial-grade systems.

An FPGA (Field Programmable Gate Array) is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all of which can be reconfigured after manufacture. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs) between simple CPLDs and high-density SoC FPGAs, and they are widely used for digital logic prototyping, custom interface bridging, and small-volume hardware acceleration where ASIC NRE costs are prohibitive. The FLEX 8000 series pioneered in-circuit reconfigurability (ICR) via an external serial or parallel configuration EPROM, allowing field updates without removing the device from the board.

Key features of the EPF8820AQC160-2 include 120 user I/O pins supporting 5 V PCI-compliant signaling, a built-in JTAG (IEEE 1149.1) boundary-scan test interface, and a hierarchical interconnect architecture that routes signals between logic elements through fast local and global routing resources. The device supports both synchronous and asynchronous design styles, and its rich register count (approximately 712 flip-flops across the 672 logic elements) makes it well suited to pipelined datapaths and control logic with significant state-holding requirements.

From a technical perspective, the FLEX 8000 architecture implements each logic element as a 4-input look-up table (LUT) feeding a programmable register, with carry-chain support for fast arithmetic. The SRAM configuration memory means the device is volatile and must be loaded at power-up, typically from a serial configuration PROM such as the EPC1 or EPC2. The -2 speed grade indicates a mid-tier timing closure suitable for most commercial designs at clock rates up to 125 MHz.

Typical applications include PCI bus interface bridges, custom peripheral controllers for legacy microprocessors, glue logic replacing multiple 74-series TTL devices, industrial control boards with moderate logic density, and telecommunications line-card interface logic. The 160-pin PQFP package is easy to hand-prototype and rework, making the EPF8820AQC160-2 a popular choice for low-volume production and engineering development platforms.

When designing with this device, ensure the configuration memory solution (EPC1/EPC2 or compatible) is correctly wired to the dedicated configuration pins (nCONFIG, nSTATUS, CONF_DONE, DCLK, DATA0). Because the configuration is SRAM-based, plan for deterministic power-up behavior, and add JTAG boundary-scan to simplify board test.
