EPF8820AQC208-2N Ringkasan

The Intel (formerly Altera) EPF8820AQC208-2N is a CMOS SRAM-based FLEX 8000 family FPGA with approximately 8,000 usable gates and 672 logic elements, packaged in a 208-pin Power Quad Flat Pack (PQFP/QFP). The device supports 152 user I/O pins, runs from a 5 V supply, and is fabricated on a 0.42 µm CMOS process node, achieving a maximum toggle frequency around 125 MHz with a propagation delay of roughly 5 ns.

An FPGA (Field-Programmable Gate Array) is a programmable logic device that integrates configurable logic blocks, programmable interconnect, and I/O cells on a single die. Within the broader semiconductor taxonomy, FPGAs sit alongside CPLDs, microcontrollers, and ASICs as the dominant platforms for digital logic implementation. The FLEX 8000 family specifically targets register-rich, glue-logic and bus-integration applications, sitting hierarchically between low-density PLDs and high-density ASICs.

Key features of the EPF8820AQC208-2N include 672 logic elements, 152 user I/O pins, JTAG-based in-system reconfigurability via the ByteBlaster interface, four dedicated fast inputs, multiVolt I/O support for 3.3 V and 5 V interfaces, and a global low-skew clock network. The device uses a continuous SRAM configuration architecture, so it must be configured at every power-up by an external EPROM, an Altera EPC1/EPC1441 configuration device, or a system controller.

Architecturally, FLEX 8000 devices use a Logic Array Block (LAB) structure of 8 logic elements per LAB with shared carry chains and cascade paths, surrounded by a FastTrack Interconnect routing fabric. The embedded memory array holds the configuration bitstream, enabling live reconfiguration but making the part inherently volatile. The 5 V core and I/O operate at commercial temperature grade (0 to 70 °C), with the part produced under the FLEX 8000 family datasheet umbrella.

Typical applications include high-speed bus bridges, peripheral controllers in telecom and networking, industrial machine control glue logic, prototyping for ASIC replacement, and bus-intensive designs such as 32-bit RISC/CISC peripheral glue. The 152 I/O pins accommodate multiple parallel buses in a single device, eliminating external bus-multiplexing logic.

When designing with this part, ensure that configuration is supplied on every power-up using an EPC-series configuration device or microcontroller, and observe 5 V VCCINT and VCCIO decoupling guidelines. The part is EOL/legacy; new designs should consider Cyclone or MAX families.
