EPF8820ARI208-2 Présentation

The Altera EPF8820ARI208-2 is a member of the FLEX 8000 family of SRAM-based Field Programmable Gate Arrays (FPGAs) housed in a 208-pin RQFP/RFP package. It provides 672 logic elements (LEs) and a maximum of 152 user I/O pins, with logic capacity suitable for glue logic, state-machine control, and small to mid-complexity datapath designs in industrial, telecommunications, and embedded systems. The device integrates 6 embedded array blocks (EABs) totaling approximately 16 Kbits of SRAM, configurable as RAM, ROM, or FIFO. Architecture highlights include FastTrack interconnect, look-up table (LUT) based logic, and a fine-grained, register-rich fabric.

An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor device whose logic function is defined by configuration bitstream rather than fixed metal mask. FPGAs sit at the top of the programmable logic hierarchy: programmable logic device (PLD) -> complex PLD (CPLD) -> FPGA. SRAM-based FPGAs such as the FLEX 8000 family are volatile and must be reconfigured at every power-up from an external memory (EPROM) or Altera serial configuration device (EPC1, EPC1213, EPC1064, EPC1441).

Key features of the EPF8820ARI208-2 include 672 logic elements, 152 maximum user I/O pins, 6 embedded array blocks (EABs) of 2 Kbits each, in-system reprogrammability via JTAG, and a typical gate count of 8,000 usable gates. The -2 speed grade indicates a moderate-speed bin of the silicon, suitable for cost-sensitive commercial designs. The device supports multiple I/O standards including TTL and CMOS, allowing flexible interfacing to legacy and modern logic families.

The FLEX 8000 architecture uses a four-input LUT per logic element with a dedicated register, providing predictable timing and a register-to-logic ratio well-suited for pipelined datapaths. The FastTrack continuous routing fabric and row/column interconnect provide predictable delays independent of placement, simplifying static timing closure in mid-complexity designs.

Typical applications include industrial control logic, telecommunications interface glue, prototyping platforms for ASIC emulation, and educational hardware design. The wide I/O count (152 user pins) allows direct connection to parallel buses, memory interfaces, and multiple peripheral buses without external bus expander logic. The SRAM configuration also enables rapid design iteration via JTAG or EPC device reprogramming.

When designing with the EPF8820ARI208-2, ensure an external configuration memory is selected because the SRAM configuration is volatile. The 208-pin package provides ample I/O but requires a 4-layer PCB with controlled-impedance traces for stable operation above 50 MHz. JTAG programming via the Altera ByteBlaster or compatible download cable is the standard development flow.
