EPF8820ATI144-2 Ringkasan

The Intel (formerly Altera) EPF8820ATI144-2 is a member of the FLEX 8000 family of CMOS Field-Programmable Gate Arrays (FPGAs), delivering 672 logic elements (LEs) in a 144-pin Plastic Quad Flat Pack (PQFP) package with 112 user I/O pins and 4 dedicated inputs. It is graded for the industrial temperature range and operates from a 4.5V to 5.5V single supply with a nominal VCC of 5V.

An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells, allowing the designer to implement arbitrary digital logic after PCB fabrication. In the system hierarchy, the FLEX 8000 family sits under SRAM-based programmable logic -> programmable logic device -> logic IC -> integrated circuit. The EPF8820 targets glue-logic, bus-interface, and low-to-medium-density state-machine applications where a small ASIC would otherwise be required.

Key features include 1.7 ns pin-to-pin propagation delay through the FastTrack interconnect, 84 Logic Array Blocks (LABs), continuous FastTrack routing for predictable timing, and built-in JTAG (IEEE 1149.1) boundary-scan support. The 0.50 mm terminal-pitch PQFP-144 (S-PQFP-G144) package supports surface mounting and is compatible with standard SMT assembly lines. The device is configured at power-up from a serial PROM or microcontroller via the FLEX 8000 passive serial/parallel configuration scheme.

Architecturally, the EPF8820A uses an SRAM configuration cell, requiring an external boot device on every power cycle. Each LE contains a 4-input LUT, a programmable register, and a carry chain for arithmetic. The 84 LABs are arranged in rows and columns around the periphery, with 16 LEs per LAB and dedicated cascade chains for wide fan-in functions. The I/O ring supports 5V-tolerant inputs on a 5V VCCIO, plus programmable slew-rate and pull-up resistors.

Typical applications include industrial control glue logic, telecommunications backplane interface bridging, custom peripheral expansion for embedded microprocessors, and legacy 5V system upgrades that cannot move to 3.3V FPGAs. The 1.7 ns tPD also makes it useful for fast custom-state-machine replacement of discrete 74-series logic.

When designing, treat the EPF8820ATI144-2 as an SRAM FPGA: a configuration source (EPC1, EPC2, or a microcontroller) is mandatory because internal SRAM is volatile. Ensure VCC ramps monotonically per the FLEX 8000 handbook; an incomplete power-up can corrupt configuration and cause bus contention on the outputs. Place a 0.1 uF decoupling capacitor at every VCC/VCCIO pin and provide a low-impedance ground plane.
