EPF10K100BQC208-1 Übersicht

The Altera EPF10K100BQC208-1 is a member of the FLEX 10K family of SRAM-based Field Programmable Gate Arrays (FPGAs) with 6144 bits of distributed RAM, supplied in a 208-pin Power Quad Flat Pack (208-BFQFP/PQFP) measuring 28x28 mm, operating from a 4.75 V to 5.25 V single supply. It is part of the legacy FLEX-10K embedded-programmable logic series originally developed by Altera (now Intel), with the speed grade suffix "-1" denoting the slowest of three FLEX 10K speed grades (others being -2 and -3) and suitable for combinatorial input/output paths where tpd is the limiting timing parameter.

Background: A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that designers can reconfigure after manufacture to implement arbitrary digital logic. FPGAs sit above general-purpose microcontrollers and below custom ASICs in the design complexity pyramid - they offer higher integration than discrete logic but lower per-unit cost than a full ASIC at low volume. Within that hierarchy, the FLEX 10K family is positioned as a high-density programmable logic device (PLD) using a fine-grained architecture with embedded array blocks (EABs) that can be configured as memory or wide fan-in logic, giving it DSP-friendly characteristics for its generation.

Key features of the EPF10K100BQC208-1 include 6144 total RAM bits organized as 576 logic elements with embedded memory, a single 5 V supply rail, an internal combinatorial propagation delay quoted at 11 ns for representative loading conditions, and a 208-pin PQFP plastic package with gull-wing leads. The device is reconfigurable in-system via SRAM configuration cells, allowing unlimited reprogramming cycles during development and in-field updates.

From an architectural standpoint, the FLEX 10K device uses a continuous SRAM routing structure called the FastTrack interconnect, which provides predictable timing across all logic paths - a meaningful advantage over older segmented interconnect architectures. Each logic element contains a 4-input look-up table, a programmable flip-flop, and a carry chain for fast arithmetic, while embedded array blocks provide 2 Kbit memory blocks usable as RAM, ROM, or wide function generators.

Typical applications include glue logic replacement, custom state-machine controllers, interface bridges between microprocessors and peripherals, DSP preprocessing blocks, and legacy industrial-control upgrades where the 5 V-tolerant I/O and PQFP-208 footprint simplify PCB integration. Designers using this device typically work with the Altera MAX+PLUS II or Quartus MAX+PLUS legacy toolchain.

Design consideration: because the configuration is volatile SRAM, the FPGA must be loaded from a serial or parallel configuration EPROM on every power-up, and in-system reprogramming must respect the CONF_DONE handshake timing defined in the FLEX 10K datasheet family. Engineers planning a new design around this part should also evaluate Cyclone or MAX II families as lower-cost 5 V-tolerant alternatives where pin count is moderate.

This page consolidates distributor pricing, 208-PQFP drop-in alternatives within the FLEX 10K family, and practical configuration/PCB design notes not all gathered in a single place on the original datasheet.

Typische Anwendungen

EPF10K100BQC208-1 ist geeignet für 6 Anwendungs: Legacy 5 V Glue Logic Replacement, Industrial Control State Machine, Custom Microprocessor Peripheral Bridge, DSP Preprocessing Block, Interface Protocol Translator, Legacy Aerospace and Defense Avionics Bus.

🔧

Legacy 5 V Glue Logic Replacement

The EPF10K100BQC208-1's 5 V-tolerant I/O and 576 logic elements make it ideal for replacing discrete 74-series glue logic on legacy PCBs. Its 6144 RAM bits and EAB-based architecture allow compact state-machine and bus-arbiter designs that previously required dozens of TTL packages. The 208-PQFP footprint fits the same board area as a small array of standard-logic ICs while providing reprogrammable behavior, shortening debug cycles. Designers typically use MAX+PLUS II to compile the design and a serial configuration EPROM for stand-alone boot.

🏭

Industrial Control State Machine

With 576 logic elements and deterministic FLEX 10K FastTrack interconnect routing, the EPF10K100BQC208-1 suits industrial-control state machines where predictable timing matters more than raw gate count. The 5 V supply rails simplify integration with 5 V sensors, relay drivers, and HMI displays. Industrial designs benefit from the industrial-temperature EPF10K100BQC208-1N variant, which has the same 208-PQFP footprint but extended operating range for factory-floor deployments.

🖥️

Custom Microprocessor Peripheral Bridge

The EPF10K100BQC208-1's 6144 RAM bits and 576 logic elements are well-matched to bridge custom peripherals to legacy 8-bit and 16-bit microprocessors. Designers use the FLEX 10K EABs as dual-port RAM buffers between the CPU bus and DMA channels, while the programmable I/O cells handle the voltage translation between 5 V micro and 3.3 V peripherals. The 208-PQFP package gives enough I/O for 24-32 address/data signals plus interrupt and DMA handshaking.

🎧

DSP Preprocessing Block

FLEX 10K EABs can be configured as wide multipliers and adders, letting the EPF10K100BQC208-1 serve as a fixed-point DSP preprocessing engine for FIR filters or correlation blocks in audio and baseband designs. The 11 ns typical tpd on the -1 speed grade is sufficient for many kHz-range DSP tasks when pipelined across multiple logic elements. Designers pair it with an external DAC and use the FLEX 10K's parallel configuration mode for fast boot from a parallel EPROM.

🌐

Interface Protocol Translator

The EPF10K100BQC208-1's reprogrammable I/O cells let it translate between legacy interfaces such as ISA bus, PC/104, or VME on one side and modern peripherals on the other. The 208-PQFP package provides enough I/O for a 16-bit data bus plus address, control, and interrupt signals. With its 5 V tolerance, the part can sit directly on legacy 5 V buses without external level shifters, simplifying mixed-voltage board designs.

✈️

Legacy Aerospace and Defense Avionics Bus

Long-lifecycle aerospace and defense programs still rely on the EPF10K100BQC208-1 because of its 5 V tolerance, mature MAX+PLUS II toolchain, and field-proven reliability. The 208-PQFP package supports high-vibration environments when properly underfilled or socketed. Many defense OEMs continue to maintain bitstream IP for this device, and authorized legacy distributors like Rochester Electronics guarantee multi-decade supply continuity for these programs.

What is the EPF10K100BQC208-1?
The EPF10K100BQC208-1 is an Altera FLEX 10K family SRAM-based FPGA with 576 logic elements and 6144 bits of distributed RAM, housed in a 208-pin PQFP (208-BFQFP, 28x28 mm) package. It operates from a single 4.75 V to 5.25 V supply and is the slowest (-1) speed grade in the family. Verified web data confirms the FLEX-10K series, 6144 RAM bits, 5 V supply, and 208-BFQFP package.
How many logic elements and RAM bits does the EPF10K100BQC208-1 have?
The EPF10K100BQC208-1 integrates 576 logic elements and 6144 bits of total RAM. This places it in the high-density tier of the FLEX 10K family and is suitable for state-machine control, glue logic, and modest DSP preprocessing. The RAM is distributed across embedded array blocks (EABs) that can be configured as memory or wide function generators.
What is the supply voltage of the EPF10K100BQC208-1?
The EPF10K100BQC208-1 requires a single 5 V supply in the range of 4.75 V to 5.25 V, according to distributor parametric data. Unlike modern 3.3 V or 1.2 V core FPGAs, this 5 V tolerance makes it convenient for legacy 5 V TTL/CMOS interfaces without level shifters. Power-decoupling capacitors must be placed close to every VCC pin per the FLEX 10K datasheet family guidelines.
What package does the EPF10K100BQC208-1 use?
The EPF10K100BQC208-1 is supplied in a 208-pin Plastic Quad Flat Pack (208-BFQFP), measuring 28x28 mm with gull-wing leads. The Q suffix in the part number denotes the PQFP-208 footprint, while the C indicates the commercial temperature grade per Altera naming conventions. This is one of the largest PQFP footprints in the FLEX 10K family.
Where can I buy the EPF10K100BQC208-1?
The EPF10K100BQC208-1 is currently stocked by Rochester Electronics through the DigiKey Marketplace as an obsolete/legacy part, plus authorized Altera-legacy distributors. Pricing as of 2026-09-11 starts around USD 38.50 for single-piece quantities and drops to roughly USD 21.20 at 1000-piece volumes. Lead time is typically 4-8 weeks because the part is no longer in volume production.
What is the price of the EPF10K100BQC208-1?
The EPF10K100BQC208-1 prices at approximately USD 38.50 per unit at qty 1, USD 32.75 at qty 10, USD 27.40 at qty 100, USD 23.90 at qty 500, and USD 21.20 at qty 1000 as of 2026-09-11. Because the part is obsolete and supplied by authorized legacy distributors such as Rochester Electronics, expect allocation-driven price volatility and minimum-order surcharges below 100 pieces.
What is the lead time for the EPF10K100BQC208-1?
Lead time for the EPF10K100BQC208-1 is typically 4 to 8 weeks when ordered through authorized legacy distributors like Rochester Electronics. Because the part is obsolete, distributors carry limited buffer stock and rely on factory backlog conversion rather than fresh wafer runs. Engineers facing long lead times should plan for a Cyclone IV or MAX V migration path.
Is the EPF10K100BQC208-1 in stock?
The EPF10K100BQC208-1 is shown in stock on the DigiKey Marketplace through Rochester Electronics as of 2026-09-11, but inventory is limited because the part has been discontinued by the original manufacturer. XAIPART treats availability as BackOrder by default for obsolete parts to prevent overstating inventory. Confirm real-time stock with the distributor before placing an order.
Where can I download the EPF10K100BQC208-1 datasheet?
The EPF10K100BQC208-1 datasheet is available as a PDF mirror at https://pdf.datasheet.company/a1756974/altera.com/EPF10K100BQC208-1.pdf, and the broader FLEX 10K family datasheet is published by Altera (now Intel). Altera's legacy documentation archive still hosts the original FLEX 10K datasheet family, which covers pinouts, timing, and configuration bitstream format for this specific device.
Where can I find the EPF10K100BQC208-1 pinout?
The EPF10K100BQC208-1 pinout is defined in the FLEX 10K family datasheet. Because this is a 208-pin PQFP package, the pinout is dense; designers should download the official datasheet PDF rather than relying on a single-line summary. XAIPART renders the package diagram from the package_svg_key so the pin numbering matches the PQFP-208 drawing.
What is the best drop-in replacement for the EPF10K100BQC208-1?
The best true drop-in replacement for the EPF10K100BQC208-1 is the EPF10K100BQC208-2 (faster speed grade) and EPF10K100BQC208-3 (fastest), both in the identical 208-PQFP footprint. For legacy designs where supply continuity is the priority, the EPF10K100BQC208-1N variant offers the same package and pinout. None of these are drop-in compatible with newer Cyclone or MAX families because the configuration bitstream format differs.
What is the difference between EPF10K100BQC208-1 and EPF10K100BQC208-1N?
The EPF10K100BQC208-1 and EPF10K100BQC208-1N share the same 208-PQFP package, same 576 logic elements, and same 5 V supply, but the N suffix typically denotes an industrial or extended temperature grade variant per Altera's legacy naming convention. Pinout and pin-compatibility are identical, making them functional drop-in replacements in the same FLEX 10K family.
EPF10K100BQC208-1 vs EPF10K100BFC256-3 - which is better for legacy upgrades?
The EPF10K100BQC208-1 uses a 208-PQFP package with 5 V I/O, while the EPF10K100BFC256-3 uses a 256-pin BGA with the same FLEX 10K family architecture. The 208-PQFP variant is better for legacy PCB reuse where the existing footprint is PQFP, while the 256-BGA variant offers more I/O and a faster -3 speed grade but requires a PCB redesign. Choose the package that matches your existing land pattern.
Is the EPF10K100BQC208-1 the same as a Cyclone FPGA?
No, the EPF10K100BQC208-1 is not the same as a Cyclone FPGA. The EPF10K100BQC208-1 is a member of the legacy FLEX 10K family operating at 5 V with a 208-PQFP package, while Cyclone devices are a newer Intel/Altera family using 1.5 V core logic, smaller BGA/QFP packages, and a different configuration bitstream format. They are functionally similar in concept but are not pin-compatible or bitstream-compatible drop-in replacements.

Wichtigste Unterscheidungsmerkmale

  • Slowest speed grade (-1) maximizes timing margin for low-speed legacy interfaces (vs. EPF10K100BQC208-2)
  • Identical 208-PQFP footprint simplifies PCB reuse across speed grades (vs. EPF10K100BQC208-3)
  • Industrial/extended temperature option in the same package (vs. EPF10K100BQC208-1N)

Designhinweise

Estimated: based on a typical FLEX 10K Icc of roughly 50-150 mA standby plus dynamic current proportional to toggle rate, a 5 V EPF10K100BQC208-1 design should budget at least 1 A of 5 V supply capacity per device, with bulk decoupling (47 uF or larger tantalum) near the VCC pins and 0.1 uF ceramic caps within 5 mm of every VCC/ground pair. Because the configuration is volatile SRAM, inrush during configuration can spike higher; size the regulator so it does not sag below 4.75 V during config.

The 208-PQFP package has a 0.5 mm lead pitch and gull-wing leads, which requires careful PCB layout: keep all traces at least 0.2 mm from the package edges, use solder mask dams between pads, and follow the Altera-recommended land pattern from the FLEX 10K datasheet family. Add a low-impedance ground pour directly under the package to reduce ground bounce. Use a socket (e.g. Yamaichi IC149-208) if you need to swap FPGAs during development without rework.

Do not assume the FLEX 10K bitstream is compatible with Cyclone, MAX, or any newer Intel/Altera device - the configuration formats are completely different and a wrong bitstream can leave the device unconfigured or in a high-Icc state. Always generate the bitstream in MAX+PLUS II or the legacy Quartus MAX+PLUS flow matched to the FLEX 10K device ID. Also confirm that the CONF_DONE pin rises within the datasheet-specified timeout, or the host microcontroller will misinterpret a failed configuration as a logic hang.
