EPF8282ATI100-4N Tóm tắt

The Intel / Altera EPF8282ATI100-4N is a member of the FLEX 8000 family of CMOS SRAM-based programmable logic devices, delivering 208 logic elements (LEs) and 282 flip-flops in a 100-pin TQFP (S-PQFP-G100) industrial-temperature package. The device features a 5 V core supply, in-system programmability via an EPROM/EEPROM controller, and is built on a 0.42 µm CMOS process with four-sided I/O flexibility. This part corresponds to the -4 speed grade, the slowest of the FLEX 8000 family grades, traded off for the lowest unit cost.

What is a FLEX 8000 FPGA? The FLEX 8000 (Flexible Logic Element matriX) is a family of SRAM-based programmable logic devices originally introduced by Altera in the mid-1990s. Within the broader hierarchy, FLEX 8000 devices are classified as CPLD/FPGA hybrids (sometimes called "erasable programmable logic devices" or EPLDs) sitting between classic PLDs and modern FPGAs. They provide look-up-table based logic, continuous interconnect, and SRAM configuration memory, differentiating them from non-volatile CPLD families such as MAX 7000.

Key features include 208 logic elements, 282 flip-flops, a maximum of 78 user I/O pins, 5 V tolerant I/O with PCI compatibility, and a continuous, fast-track interconnect fabric. The device supports JTAG boundary-scan testing (IEEE 1149.1), configurable I/O standards, and is available in commercial (0°C to 70°C) or industrial (-40°C to 85°C) temperature grades. The -4N suffix indicates an industrial operating range.

Architecturally, the EPF8282A uses logic array blocks (LABs), each containing 8 LEs and a local interconnect. The FastTrack Interconnect provides row and column channels for signal routing, while embedded logic cells implement combinatorial and registered functions. The chip supports a system clock from a dedicated input or any user I/O.

Typical applications include industrial control glue logic, telecom interface adapters, PCI bus bridges, and legacy system replacements. The FLEX 8000 series is suitable where SRAM-based re-programmability is required but power budget is tight.

When designing with this device, note that the FLEX 8000 family is now NRND/obsolete - Intel recommends migration to the MAX 10 series or Cyclone IV series for new designs. Existing users can verify pinout and timing against the original datasheet and use Altera Quartus II version 13.0 or earlier for legacy support.
