EPF10K10AQC208-2 概覽
The Intel EPF10K10AQC208-2 is a member of the FLEX-10KA family of Field-Programmable Gate Arrays (FPGAs) housed in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) measuring 28x28 mm. The device integrates 576 logic elements, 72 logic array blocks (LABs), and 134 user I/O pins, with 6144 bits of embedded RAM. It operates from a 3.0 V to 3.6 V supply, uses 0.3 um CMOS SRAM process technology, and supports a maximum internal frequency of 142.86 MHz. Speed grade -2 corresponds to a maximum internal propagation delay in the medium-speed range.
What is an FPGA? A Field-Programmable Gate Array is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs/LABs), programmable interconnects, and I/O cells, allowing the designer to implement arbitrary digital logic after fabrication. FPGAs occupy the middle ground between fixed-function ASICs and software-programmable microcontrollers, providing hardware-timed parallelism and reprogrammability. The FLEX-10KA family sits within the broader taxonomy of programmable logic devices (PLDs) -> FPGAs -> SRAM-based LUT FPGAs -> legacy/low-density FPGAs, and was historically used for glue logic, bus interfacing, and DSP pre-processing in telecom and industrial systems.
Key features of the EPF10K10AQC208-2 include embedded array blocks (EABs) for memory or multiplier functions, JTAG-compliant boundary-scan test support, in-system programmability via the serial configuration EPROM interface, and 5V-tolerant I/O on selected pins. Each LAB combines 8 logic elements with a carry chain, while each EAB provides up to 2048 bits of dual-port RAM.
Architecture: the FLEX-10KA device fabric uses a four-input look-up table (LUT) per logic element, fast row-and-column interconnect, and dedicated carry chains for arithmetic. The 0.3 um process delivers predictable timing closure for designs up to several thousand gates, with the FastTrack interconnect minimizing routing congestion.
Typical applications include legacy industrial control, telecom glue logic, prototyping interfaces to legacy buses (PCI, ISA, VME), DSP pre-processing, and educational platforms. The 208-pin PQFP footprint is still widely supported in long-lifecycle industrial designs.
Design consideration: the EPF10K10AQC208-2 requires an external configuration EPROM (EPC1/EPC2) on every power-up, since the SRAM-based fabric is volatile; designers must budget for the configuration circuit and the POR (power-on reset) timing.
This page synthesizes distributor pricing, FLEX-10KA family variants, and practical configuration/design notes that go beyond what is printed in the original Altera FLEX-10KA datasheet.

典型應用
EPF10K10AQC208-2 適用於 6 應用s: Legacy Industrial Control Logic, Telecom Glue Logic / Channel Card, PCI / ISA Bridge Prototyping, DSP Pre-Processing Front-End, Educational / University FPGA Trainer, Aerospace & Defense Legacy Spares.
Legacy Industrial Control Logic
The EPF10K10AQC208-2 fits legacy industrial control designs that need glue-logic integration on a 3.3 V rail with predictable timing closure. Its 576 logic elements and 72 LABs are enough for state machines, I/O conditioning, and protocol bridging on a 208-PQFP board that has been in production since the late 1990s.
推薦
Telecom Glue Logic / Channel Card
In legacy telecom line cards and channel banks, the EPF10K10AQC208-2 served as glue logic between TDM buses, framer ICs, and backplane transceivers. Its 134 user I/O and bidirectional FastTrack interconnect supported 8-bit datapaths at 50 MHz, while 6144 bits of distributed RAM sufficed for small FIFOs and look-up tables.
推薦
PCI / ISA Bridge Prototyping
The EPF10K10AQC208-2 was widely used as a PCI-to-ISA bridge prototyping platform because its 134 I/O pins map easily to the 49-pin PCI bus plus 24-bit address/data ISA bus. Designers leverage the 3 EABs (2048 bits each) to implement small FIFOs and the 0.3 um process timing to meet the 33 MHz PCI clock domain.
推薦
DSP Pre-Processing Front-End
For DSP pre-processing in audio and baseband applications, the EPF10K10AQC208-2 implements FIR filters, FFT bit-reversal, and gain control in parallel hardware. With 576 logic elements and a 142.86 MHz internal frequency, the part easily delivers 30-40 MHz sample rates for 16-bit audio or low-MHz IF baseband signals.
推薦
Educational / University FPGA Trainer
Universities still use the EPF10K10AQC208-2 in legacy Altera UP2/UP3 education boards because the 208-PQFP through-hole-friendly footprint simplifies hand-soldering and the 3.3 V supply is forgiving. Quartus II Web Edition still supports the part, making it ideal for introductory Verilog/VHDL labs.
推薦
Aerospace & Defense Legacy Spares
Long-lifecycle aerospace and defense systems with FLEX-10KA on the bill-of-materials still source the EPF10K10AQC208-2 for spares and depot repairs. Because PCN/EOL cycles for these programs span 20-30 years, the obsolete status of the part is acceptable when paired with rigorous traceability and counterfeit-screening.

Is EPF10K10AQC208-2 still in production?
No. The EPF10K10AQC208-2 is an obsolete FLEX-10KA part that has been out of production for many years. According to distributor stock data, only aftermarket and broker inventory remains. For new designs, Intel recommends migrating to the Cyclone, Cyclone II, or Cyclone III families, which are footprint-incompatible but tool-compatible via Quartus.
What is the supply voltage of EPF10K10AQC208-2?
The EPF10K10AQC208-2 operates from a single 3.3 V supply with an allowed range of 3.0 V to 3.6 V. According to the FLEX-10KA datasheet, the device also uses an internal charge pump to generate the programming voltage for the SRAM configuration cells, so no external VPP is required.
Where to buy EPF10K10AQC208-2 online?
EPF10K10AQC208-2 is available from authorized distributors like DigiKey and Mouser in very limited stock, and from independent brokers such as Avnet, Arrow, Microchip-Price, Jotrin, and Avaq as of 2026-09-11. Pricing on the secondary market typically ranges USD 22-33 per unit in small quantities and can rise sharply for production volumes.
What is the price of EPF10K10AQC208-2?
The EPF10K10AQC208-2 was last listed around USD 33 per unit at qty-1 as of 2026-09-11 according to seekic.com distributor data. Volume pricing drops to roughly USD 22-24 at qty-1000. Because the part is obsolete, prices fluctuate with broker inventory and lead times can stretch to 8-20 weeks.
What is the lead time for EPF10K10AQC208-2?
Lead time for the EPF10K10AQC208-2 as of 2026-09-11 is typically 8-20 weeks from independent brokers, since authorized distributor stock is largely depleted. The Altera/Intel FLEX-10KA family reached end-of-life more than a decade ago. Buyers should request a full trace and qualification report before committing to volume orders.
EPF10K10AQC208-2 vs EPF10K100EFC484-1 - which is better for new designs?
The EPF10K10AQC208-2 (10K gates, 576 LEs, PQFP-208) is obsolete and only fits legacy boards, while the EPF10K100EFC484-1 (100K gates, ~5000 LEs, FBGA-484) is the modern drop-in upgrade path within the same FLEX-10KE family. For new designs, prefer the EPF10K100EFC484-1 and migrate to a Cyclone IV/V device for long-term availability.
When should I choose EPF10K10AQC208-2 over a Cyclone II FPGA?
Choose the EPF10K10AQC208-2 only when you must maintain an existing 208-PQFP PCB footprint or replicate a legacy bitstream - it is drop-in compatible with EPF10K10AQC208-1 and EPF10K10AQC208-3 in the same package. For any new design, choose a Cyclone II/IV/V FPGA: you get more logic, lower power, modern tools, and an active product lifecycle, but you must redesign the PCB.
What is the best drop-in replacement for EPF10K10AQC208-2?
The best drop-in replacement for the EPF10K10AQC208-2 in the same 208-PQFP footprint is the EPF10K10AQC208-1 (faster speed grade -1, otherwise identical). For the same family with more logic in a larger package, the EPF10K30AQC208-1 or EPF10K50AQC208-1 keep the 208-PQFP footprint and double or quintuple the available logic.
Can EPF10K10AQC208-1 replace EPF10K10AQC208-2?
Yes, the EPF10K10AQC208-1 is a direct drop-in replacement for the EPF10K10AQC208-2. Both parts share the same 208-PQFP package, 576 logic elements, 72 LABs, 134 user I/O, and 3.3 V supply; the only difference is the speed grade (-1 is faster than -2). The bitstream and PCB layout are unchanged.
Where to download EPF10K10AQC208-2 datasheet PDF?
The official FLEX-10KA datasheet covering the EPF10K10AQC208-2 is hosted at the Intel/Altera literature archive at https://www.altera.com/literature/ds/dsf10ka.pdf. The device-specific pinout and timing tables are in the EPF10K10A Device-Specific Pin-Out file on the same Altera literature server. Both documents are freely accessible without registration.
Where can I find the EPF10K10AQC208-2 pinout?
The EPF10K10AQC208-2 pinout is published in the EPF10K10A Device-Specific Pin-Out PDF on the Altera/Intel literature server and reproduced on distributor product pages like DigiKey and Mouser. The 208-PQFP package assigns pins 1-208 around the perimeter; full signal names (I/O banks, JTAG, configuration, power, GND) are tabulated in the pinout file.
What configuration EPROM does EPF10K10AQC208-2 need?
The EPF10K10AQC208-2, like all FLEX-10KA devices, requires an Altera serial configuration EPROM (EPC1, EPC2, or EPC1064) on every power-up because the SRAM configuration cells are volatile. According to the FLEX-10KA datasheet, the EPC2 is the most common choice because it supports in-system reprogramming via JTAG and stores up to 2 Mbit of configuration data.
Is EPF10K10AQC208-2 RoHS compliant?
No. The EPF10K10AQC208-2 is a legacy PQFP package that contains lead in its leads and plating, and it is not RoHS-compliant. According to distributor compliance data, the part is classified as non-RoHS. For RoHS-compliant FLEX-10KA replacements, designers must migrate to the FLEX-10KE family in QFP/QFN/BGA packages, which Intel offers in lead-free finishes.

選型指南
Choose the EPF10K10AQC208-2 when you must maintain an existing 208-PQFP board design that already routes to a FLEX-10KA pinout - it remains pin-compatible with the EPF10K10AQC208-1, EPF10K10AQC208-3, EPF10K30AQC208-2, and EPF10K50AQC208-2, so the same PCB can be re-populated to scale up logic density or speed grade without layout changes. Pick EPF10K10AQC208-1 if you need higher Fmax, EPF10K30AQC208-2 if you need 3x logic, or EPF10K50AQC208-2 if you need 5x logic. Choose the EPF10K10ATC144-2 only if you redesign the PCB for a 144-TQFP footprint (it is NOT drop-in compatible with the 208-PQFP). For any new design, migrate to a Cyclone II/IV/V FPGA and the Quartus Prime toolchain, since the entire FLEX-10KA family is end-of-life and broker-only stock is the long-term supply.

主要差異化特點
- Same-density 208-PQFP variant in a faster speed grade (對比EPF10K10AQC208-1)
- Three-fold logic density in the same 208-PQFP footprint (對比EPF10K30AQC208-2)
- Five-fold logic density in the same 208-PQFP footprint (對比EPF10K50AQC208-2)
設計說明
The EPF10K10AQC208-2 SRAM configuration is volatile: without an external configuration EPROM (EPC1/EPC2) the device will not boot on power-up. Designers must include the configuration circuit on every board revision and verify nSTATUS, CONF_DONE, and nCONFIG timing against the FLEX-10KA handbook. Failure to do so is the single most common reason legacy FLEX-10KA boards fail to come up after reflow or firmware update.
The 208-PQFP package requires a 28x28 mm footprint with 0.5 mm pitch gull-wing leads; use 4-layer PCB with a continuous ground plane under the device to provide a low-impedance return path for the 134 high-speed I/O transitions. Place 0.1 uF decoupling capacitors as close as possible to every VCC/GND pair and add bulk 10 uF tantalum capacitors at the four VCC corners to suppress the simultaneous switching noise (SSN) generated by the FastTrack interconnect.
Long traces (>50 mm) on FLEX-10KA I/O banks should be source-terminated with a 33 ohm series resistor to control ringing at 33 MHz PCI or 50 MHz TTL edges. Use the Quartus II Assignment Editor to enable PCI clamping diode and PCI-compliant I/O standard on the relevant pins. JTAG chain integrity should be verified with the BSDL file shipped with Quartus to detect opens/shorts before functional test.
