EPF8820ATC144-10 Présentation

The Altera EPF8820ATC144-10 is a member of the FLEX 8000 family of CMOS SRAM-based FPGAs, integrating approximately 8,000 usable gates, 672 logic cells, and 84 Logic Array Blocks (LABs) in a 144-pin LQFP (Low-profile Quad Flat Pack) package. Speed grade -10 corresponds to a 10 ns pin-to-pin propagation delay through the logic element, making it the slowest member of the EPF8820A speed-grade ladder. The device is fabricated on a 0.42 µm CMOS process and operates from a 5 V supply with MultiVolt I/O capability allowing 3.3 V or 5.0 V interface voltages on all packages except specific 84-pin variants.

What is an FPGA? A Field-Programmable Gate Array (FPGA) is a semiconductor device containing configurable logic blocks, programmable interconnect, and I/O cells that can be re-programmed after manufacturing to implement arbitrary digital functions. Within the taxonomy, the EPF8820ATC144-10 sits inside the broader hierarchy: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit. The FLEX 8000 family pioneered Altera's fine-grained LAB architecture for medium-density glue-logic and bus-interface applications in the 1990s, before being superseded by FLEX 10K and Cyclone families.

Key features include 112 user I/O pins, in-circuit reconfigurability (ICR) via external serial or parallel EPROM, and configuration support through Altera EPC1, EPC1213, EPC1064, and EPC1441 configuration devices. The 144-pin LQFP package has a 0.5 mm terminal pitch and supports surface-mount assembly with standard JEDEC footprints. Operating temperature range is commercial 0 °C to 70 °C.

Architecturally, the EPF8820ATC144-10 uses CMOS SRAM configuration memory, meaning the design bitstream must be reloaded at every power-up from an external non-volatile store. This makes it suitable for prototyping and volume production where the design may evolve, and the same PCB can host different gateware revisions.

Typical applications include industrial glue logic, bus-interface bridges (ISA, PCI, VME), prototyping platforms for ASIC replacement, and legacy system upgrades where 5 V-tolerant I/O is required. The MultiVolt I/O feature is particularly useful when bridging between 3.3 V peripherals and 5 V backplanes. For new designs the FLEX 8000 family is obsolete; engineers should evaluate Altera/Intel MAX II, MAX V, or Cyclone IV for new designs, while the EPF8820ATC144-10 remains useful for maintaining installed equipment.

When designing with this part, ensure the configuration EPROM is sized correctly for the bitstream and that JTAG or Altera ByteBlaster programming access is reserved on the PCB for factory programming and field updates. Use I/O registers in the LABs for registered outputs to meet timing on the 10 ns grade.
