EPF10K100BQC208-3 Présentation
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.
This page synthesizes distributor pricing, drop-in alternatives within the FLEX-10K family, and practical design notes not found in the manufacturer datasheet alone.

Applications typiques
EPF10K100BQC208-3 convient pour 6 applications: Industrial Glue Logic Replacement, Legacy PCI Bus Bridge, Custom State Machine Controller, Telecom Line-Card Interface Logic, DSP Datapath Pre-Processing, Aerospace/Military Avionics Retrofit.
Industrial Glue Logic Replacement
The EPF10K100BQC208-3 replaces multiple 74-series TTL/CMOS logic packages with a single programmable device, reducing board area and BOM cost in long-life industrial controllers. With 4,992 cells and 6,144 RAM bits, it can absorb an entire address-decoding, interrupt-priority, and bus-arbitration tree that would otherwise require 8-12 discrete MSI chips. Its 5V PQFP package directly interfaces with legacy 5V logic without level shifters, a critical advantage for retrofitting into systems designed in the 1990s.
Recommandé
Legacy PCI Bus Bridge
The EPF10K100BQC208-3's multi-volt I/O supports 5V/3.3V PCI signaling, making it a frequent choice for custom PCI add-in cards and bus bridges in industrial PCs. Its 147 user I/Os comfortably handle a 32-bit/33 MHz PCI target interface (47 pins) plus DMA state machines, FIFOs (built from EAB RAM), and interrupt logic. The 14.5 ns speed grade easily meets the 33 MHz PCI clock-to-out requirement with timing margin to spare.
Recommandé
Custom State Machine Controller
The EPF10K100BQC208-3 excels at implementing complex multi-state controllers for factory automation, elevator controls, and HVAC sequencers that cannot be expressed in fixed-function logic. Designers can prototype in Quartus II's state-machine-entry mode and verify timing via simulation before committing. The 100K-gate capacity supports 30-50 microsequencer states with parallel datapaths and on-chip EAB-based register files, all in a single legacy-friendly PQFP.
Recommandé
Telecom Line-Card Interface Logic
In telecom line-interface cards the EPF10K100BQC208-3 implements proprietary framing, scrambling, and alarm-monitoring logic between the framer IC and the TDM backplane. Its 6,144 RAM bits are sufficient for small elastic stores / jitter buffers, and its FastTrack Interconnect delivers low-skew clock distribution to multiple parallel data paths. The 208-PQFP package is a proven choice for line cards that must remain in service for 15-20 year product lifetimes.

DSP Datapath Pre-Processing
Before the DSP era of dedicated multiply-accumulate engines, FPGAs like the EPF10K100BQC208-3 were widely used to implement FIR filters, correlators, and FFT butterflies in software-radio and instrumentation front-ends. The 100K-gate fabric can hold a 32-tap FIR plus coefficient RAM in EABs while sustaining the 200 MHz internal clock rate needed for high-sample-rate audio and baseband processing.

The full pin table is in section 4 of the FLEX-10KE datasheet and in the Quartus II pin assignment tool.
Can EPF10K100BQC208-3 replace EPF10K100BQC208-2?
Yes, the EPF10K100BQC208-3 is functionally identical to the EPF10K100BQC208-2 with a faster speed grade (14.5 ns vs ~17 ns pin-to-pin delay). Both share the same 208-PQFP package and pinout, so the -3 variant is a drop-in upgrade that improves timing margins without requiring any PCB or schematic changes.
What is the price of EPF10K100BQC208-3 as of 2026?
As of 2026-09-11, the EPF10K100BQC208-3 unit price ranges from $24.50 at 1000-piece quantity to $42.50 at qty-1, based on Octopart aggregated distributor data. Pricing reflects its last-time-buy status; secondary-market and franchised distributor Rochester Electronics typically command a premium for traceable, tested stock.
Where to buy EPF10K100BQC208-3 online?

How does EPF10K100BQC208-3 compare to Cyclone EP1C20F324I7?
The EPF10K100BQC208-3 offers 100K gates/4,992 cells in a 5V 208-PQFP, while the Cyclone EP1C20F324I7 provides 20,060 LEs in a 3.3V 324-FBGA. Cyclone is newer, lower-power, and RoHS-compliant, but is not pin-compatible - replacing EPF10K100B requires a PCB redesign, not a drop-in swap.
What is the best drop-in replacement for EPF10K100BQC208-3?
The EPF10K100BQC208-1 and EPF10K100BQC208-2 are direct drop-in replacements in the same 208-PQFP footprint with identical pinout - only the speed grade differs (-1: slowest, -2: medium, -3: fastest). The -3 variant itself is the highest speed; if unavailable, the -2 is the next-best drop-in option.
Can EPF10K100BFC256-3 replace EPF10K100BQC208-3?
No, the EPF10K100BFC256-3 is not a drop-in replacement. Although it shares the same FLEX-10KE silicon family, it ships in a 256-pin FBGA package with a different pinout and footprint. Using it requires a PCB redesign; for footprint-compatible upgrades use the EPF10K100BQC208-2 instead.
What software is used to program EPF10K100BQC208-3?
The EPF10K100BQC208-3 is programmed using Altera/Intel Quartus II (versions 9.x and earlier for FLEX-10K support) or the legacy MAX+PLUS II toolchain. Configuration bitstreams are loaded via JTAG or an external EPC series configuration PROM (EPC2, EPC8, EPC16) using the serial or parallel configuration scheme.
Is EPF10K100BQC208-3 RoHS compliant?
No, the EPF10K100BQC208-3 in its 208-PQFP package is not RoHS compliant - the PQFP finish uses SnPb (tin-lead) solder plating. The lead-free / RoHS-compliant equivalent from the same family would require moving to a different package (e.g., the BFC256 FBGA variants in some speed grades) and verifying with the distributor.
What are the key specifications engineers should know about EPF10K100BQC208-3?
The EPF10K100BQC208-3 ships in 208-PQFP, runs on a single 5V supply, integrates 100K gates with 6,144 RAM bits, supports up to 200 MHz internal operation with 14.5 ns pin-to-pin delay, exposes 147 user I/Os, and loads SRAM configuration via JTAG or external EPC boot PROM.

Guide de sélection
Choose the EPF10K100BQC208-3 when designing a 5V-only legacy industrial, telecom, or aerospace system that requires the fastest speed grade (-3, 14.5 ns tPD) within the FLEX-10KE 100K-gate family. It is the optimum pick when timing closure is critical but the 208-PQFP footprint is acceptable. Choose EPF10K100BQC208-2 as a drop-in cost-saving alternative if 17 ns tPD is acceptable; choose EPF10K100BQC208-1 if you need maximum supply longevity and the slowest speed is sufficient. For new designs, evaluate Intel's Cyclone family instead - RoHS-compliant, lower power, and modern toolchain - but budget for a PCB redesign since the FLEX-10K is not pin-compatible with Cyclone.

Notes de conception
The EPF10K100BQC208-3 requires a 5V +/- 5% core supply with decoupling consisting of one 100 uF bulk capacitor per supply rail and ten 0.1 uF ceramics distributed around the package perimeter. VCCINT and VCCIO pins must be tied together at 5V for 5V-only I/O operation. Provide at least 100 ms of power-rail rise time to ensure clean configuration; rapid power-on ramps can corrupt the SRAM bitstream.
Place the EPC configuration PROM (EPC2, EPC4, EPC8, or EPC16) within 10 cm of the FPGA to keep the DCLK signal clean. Add 33 ohm series termination on DCLK and DATA0 lines for noise margins above 50 MHz configuration clock. JTAG TCK should also be series-terminated when driving multiple devices in a boundary-scan chain.
Do not leave MSEL0/MSEL1 floating - tie to VCC or GND to select the configuration mode (PS: 00, AS: 01, JTAG: 11). nCONFIG must be pulled high through a 10 kohm resistor to VCC; do not drive it from a totem-pole source without an open-drain buffer. CONF_DONE has an open-drain output and requires an external 10 kohm pull-up.
