EPF8820ATI144-2N Visão geral

The Altera (now Intel) EPF8820ATI144-2N is a member of the FLEX 8000 family of CMOS SRAM-based programmable logic devices (PLDs) and field-programmable gate arrays (FPGAs), offering 672 logic elements in a 144-pin TQFP (TQ144) industrial-grade package with a 1.7 ns propagation delay. It is a loadable PLD that operates from a single 5V supply (4.5V to 5.5V range) and is intended for surface-mount designs requiring a moderate gate density with predictable timing.

A FLEX 8000 device is a class of SRAM-based programmable logic that combines fine-grained logic elements (LEs) with continuous interconnect and embedded array blocks (EABs) for memory functions. FPGAs in general sit within the programmable logic hierarchy (PLD -> CPLD -> FPGA) under the broader semiconductor category, and the FLEX 8000 family was Altera's mainstream high-density family prior to the MAX and Cyclone series. Unlike antifuse or flash FPGAs, FLEX 8000 parts are volatile and must be configured from an external EPROM or Altera serial configuration device (EPC1, EPC1213, EPC1064, EPC1441) at every power-up.

Key features include 672 logic elements, 1.7 ns combinatorial propagation delay (tPD), SRAM-based configuration that supports in-system re-programmability, an industrial operating temperature grade (-40C to +85C), and JTAG-erasable memory cells for fast design iteration. The 144-pin TQFP package uses gull-wing leads at 0.500 mm pitch for SMT assembly, and the device is pin-compatible with other EPF8820A TQ144 speed grades, allowing board reuse across the family.

Architecturally, the EPF8820A integrates logic elements organized into Logic Array Blocks (LABs), each containing multiple LEs with a 4-input look-up table, programmable register, and carry chain. EABs provide on-chip RAM/ROM with widths up to 16 bits. Continuous routing channels deliver predictable, deterministic timing well-suited to glue-logic, bus-interface, and state-machine roles in legacy industrial systems.

Typical applications include industrial machine control, legacy telecom interfaces, glue-logic replacement for TTL/74-series designs, custom bus controllers (ISA, PC/104, VME), and prototyping platforms where the FLEX 8000 toolchain (MAX+PLUS II or Quartus) is still in production use. The part is also common in long-lifecycle defense and aerospace programs where a stable 5V supply and industrial-temperature silicon are required.

When designing with this part, designers must provide an external configuration memory because FLEX 8000 devices lose their configuration on power-down. Plan a 5V analog supply with adequate decoupling (100 nF + 10 uF), respect the 4.5V to 5.5V supply window, and reserve board area for the EPC1/EPC1441 configuration EPROM. Programming is performed via the Altera ByteBlaster or via JTAG.
