EPF8820ATC144-3N Ringkasan

The Intel (Altera) EPF8820ATC144-3N is a member of the FLEX 8000 family of CMOS SRAM-based Field-Programmable Gate Arrays, delivering approximately 8,000 usable gates and 672 logic cells in a 144-pin TQFP (also described as 144-LFQFP) surface-mount package. It is fabricated on a 0.42 µm process node and operates from a 5 V supply within the commercial 0 °C to 70 °C temperature range. The -3 speed grade positions this device in the mid-tier of the FLEX 8000 performance spectrum, with an internal counter frequency benchmark commonly cited around 125 MHz.

What is a FLEX 8000 FPGA? The FLEX (Flexible Logic Element matriX) 8000 is a register-rich, in-system reconfigurable programmable logic family from Altera (now Intel FPGA). FPGAs in general sit within the broader taxonomy of programmable logic devices (PLD) and belong to the digital semiconductor hierarchy: logic IC -> PLD -> CPLD/FPGA -> SRAM-based FPGA. FLEX 8000 devices are configured at system power-up by loading SRAM configuration bits from an external EPROM or from Altera EPC-series serial configuration devices (EPC1, EPC1064, EPC1213, EPC1441). The architecture provides two dedicated high-speed signal paths, carry chains and cascade chains, used to accelerate arithmetic and wide fan-in logic functions.

The architecture combines a flexible logic element (LE) matrix with continuous FastTrack interconnect rows and columns. Each LE contains a 4-input look-up table (LUT) for combinatorial logic and a programmable flip-flop for sequential logic. The flip-flop clock, clear, and preset control signals can be driven by dedicated input pins, by general-purpose I/O, or by any internal logic. For purely combinatorial functions the flip-flop can be bypassed, allowing the LUT output to flow directly to the device pin.

Typical applications include glue logic replacement, interface bridging, bus protocol conversion, and small to medium state-machine controllers in industrial, telecom, and embedded systems. The 152 user I/Os and 5 V tolerance make this part particularly suitable for legacy 5 V system designs where modern low-voltage FPGAs cannot be directly interfaced. System-level features include in-circuit reconfigurability (ICR) via external configuration devices, allowing field upgrades without removing the device from the board.

Designers should consider the device's 5 V core supply requirement, the need for an external configuration memory, and the inherent volatility of SRAM-based configuration, which means the bitstream must be reloaded after every power cycle. Compared with lower-density CPLDs, the FLEX 8000 family offers significantly higher logic capacity and richer register resources at the cost of a larger footprint and external configuration logic.
