EPF10K100BQC208-3 Overview

The Altera (now Intel) EPF10K100BQC208-3 is a FLEX-10KE-family Field Programmable Gate Array (FPGA) IC delivering 100,000 typical gates, 4,992 logic elements, and 6,144 RAM bits, housed in a 208-pin PQFP (28x28 mm, FQFP/BFQFP) package. It operates from a 4.75V to 5.25V single supply with a 0.22 µm CMOS process and is specified for a 14.5 ns pin-to-pin delay (speed grade -3, 200 MHz internal performance). The FLEX-10KE family combines fine-grained look-up table logic with embedded array blocks (EABs) for on-chip RAM/ROM, and its FastTrack Interconnect continuous routing fabric delivers predictable timing across the device.

An FPGA (Field-Programmable Gate Array) is a programmable logic device that lets designers implement arbitrary digital logic using a matrix of configurable logic blocks (CLBs), programmable interconnect, and I/O cells - in the taxonomy hierarchy: logic cell -> logic element -> CLB -> FPGA -> programmable logic device (PLD) -> digital IC -> semiconductor. FPGAs occupy the middle ground between fixed-function ASICs and low-density CPLDs, offering densities from a few thousand to millions of logic elements with re-programmability via SRAM or antifuse configuration memory.

Key features of the EPF10K100BQC208-3 include 4,992 logic cells (576 logic elements per the older LEs count), 6,144 bits of embedded RAM, multi-volt I/O support for 5.0V/3.3V PCI compliance, JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan interface, and built-in low-skew clock distribution trees. The device is 100% functionally tested at the factory and supports SRAM-based configuration via an external EPROM or Altera configuration device.

Typical applications span glue-logic integration, custom state machines, bus-interface bridges (PCI, ISA), DSP datapath pre-processing, industrial control, telecommunications line-card interface logic, and legacy prototype-to-production conversion. Because the FLEX-10KE architecture is well documented and the Quartus II (legacy: MAX+PLUS II) toolchain still supports it, the part is often seen in long-life-cycle industrial and military systems.

A key design consideration is the 5V-only core supply: level translation to 3.3V peripherals must be handled externally or by selecting a 3.3V-tolerant FLEX-10K variant. Engineers should also budget for configuration time on power-up (the device loads its SRAM from an external boot PROM) and provide proper JTAG chain termination.
