EPF8820ARC-4 Ringkasan

The Intel / Altera EPF8820ARC-4 is a member of the FLEX 8000 family of SRAM-based Field Programmable Gate Arrays (FPGAs) with 672 logic elements (LEs), 152 user I/O pins, and a -4 speed grade. According to the Altera FLEX 8000 datasheet, the EPF8820ARC-4 is supplied in a 208-pin BFQFP (R-C suffix) package and operates from a 5V VCCINT with 3.3V or 5V tolerant I/O, making it compatible with mixed-voltage legacy and 3.3V ASIC interfaces.

A Field Programmable Gate Array (FPGA) is a programmable logic device containing an array of configurable logic blocks (CLBs), programmable interconnects, and configurable I/O cells. FPGAs sit in the broader hierarchy of programmable logic -> logic ICs -> integrated circuits -> semiconductors, and are used to implement arbitrary digital logic that can be reconfigured after manufacture. The FLEX 8000 family specifically targets glue logic, bus interface, and state-machine applications in telecom, industrial, and embedded systems.

Key features of the EPF8820ARC-4 include 672 logic elements (LEs), 152 user I/O pins, an embedded array block (EAB) for memory functions, and a -4 speed grade providing a balance between timing performance and power. The device supports in-system programmability via the Altera BitBlaster or ByteBlaster download cable, and configuration can be stored in serial EPROM or via the passive serial / passive parallel asynchronous modes. Compared with smaller FLEX 8000 members, the EPF8820 provides more than 3x the logic density of the EPF8282 family.

Architecturally, the EPF8820 uses Altera's Classic look-up table (LUT) approach combined with EAB blocks for efficient RAM/ROM implementation. The device is built on a 0.5 um CMOS SRAM process, which provides deterministic configuration and unlimited re-programmability but requires a configuration device at power-up. The 208-pin BFQFP package exposes both core and I/O power rails for noise decoupling.

Typical applications include telecommunications line cards, industrial control glue logic, ASIC prototyping, and legacy bus-interface bridges. Designers select the EPF8820ARC-4 when they need medium logic density with a generous I/O count in a robust surface-mount plastic QFP. The FLEX 8000 family is widely supported by the Altera (now Intel) MAX+PLUS II and Quartus design tools.

When designing with the EPF8820ARC-4, ensure a configuration EPROM (such as the Altera EPC1 or EPC2) is present at power-up since FLEX 8000 devices are SRAM-based and lose configuration when VCCINT drops. Decouple all VCCINT and VCCIO pins individually with 0.1 uF capacitors, and provide a minimum of 6 layers or a solid ground plane to suppress simultaneous switching noise on the 152 I/Os. Operating junction temperature must stay below 85C for commercial and 100C for industrial grades.
