EPF10K100BQC208-1 概要
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.

主な用途
EPF10K100BQC208-1 の用途: 6 件s: 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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.
おすすめ
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.

設計ノート
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.
