EPF8820ATI144-4N Ringkasan

The Altera EPF8820ATI144-4N is a member of the legacy FLEX 8000 family of SRAM-based Field-Programmable Gate Arrays (FPGAs), delivering 672 logic elements (LEs) organized into 84 Logic Array Blocks (LABs). Housed in a 144-pin LQFP (LFQFP) gull-wing package, the device supports configurable I/O standards for both 3.3V and 5V signaling, and is graded for industrial temperature operation. The 'N' suffix indicates lead-free / Pb-free terminal finish, and the 'I' in the package designator indicates the industrial temperature grade.

An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit whose logic functionality is defined by the customer after manufacture using a configuration bitstream loaded into on-chip SRAM. Within the broader taxonomy, the EPF8820ATI144-4N sits in the hierarchy: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit. The FLEX 8000 family specifically pioneered Altera's look-up-table (LUT) based architecture, replacing the older MAX-class EPLD technology, and bridged the gap toward modern high-density Stratix and Cyclone families.

Key features of the EPF8820ATI144-4N include 672 logic elements (8 LEs per LAB x 84 LABs), a propagation delay of 0.1 ns through the FastTrack interconnect, configurable I/O supporting 3.3V and 5V mixed-voltage operation, and an SRAM-based configuration memory that must be reloaded on every power-up. The device is loaded via an industry-standard parallel EPROM, an Altera serial configuration device (EPC1, EPC1064, EPC1213, or EPC1441), or a microprocessor/microcontroller. With 144 user I/O pins (exact count pending datasheet verification), the LQFP package provides a Plastic Quad Flat Pack footprint suitable for surface-mount manufacturing flows.

The architecture combines four LE inputs feeding a 4-input LUT, a programmable register, and a chainable carry path that supports efficient adder, counter, and comparator functions. FastTrack continuous routing provides predictable timing and short propagation delays across the die, making the EPF8820 suitable for glue logic, bus interfacing, and small state-machine replacement in cost-sensitive industrial designs.

Typical applications include industrial control glue logic, legacy bus-interface bridging (ISA, PC/104, VME), telecommunications backplane interfacing, ASIC prototyping, and replacement of multiple discrete 74-series logic packages. Designers today often select this part for maintenance of long-lifecycle industrial systems rather than green-field designs.

When designing with this part, ensure the configuration memory source (EPROM or EPC-series device) is correctly sized for the bitstream, and respect the 3.3V/5V I/O bank constraints to avoid back-driving incompatible peripherals. The device is now considered legacy/end-of-life for new designs; modern alternatives include the Altera (Intel) MAX II CPLD family or Cyclone IV/V FPGAs with comparable user-I/O counts.
