EPF10K10QC208-4N Tóm tắt

The Intel / Altera EPF10K10QC208-4N is a member of the FLEX 10K family of FPGAs that delivers 10,000 usable gates with 576 logic elements, 72 LABs/CLBs, and 134 user I/Os in a 208-pin PQFP (Plastic Quad Flat Pack) package. Fabricated on a 0.42 µm CMOS SRAM-based process and operating from a single 5 V supply, the device supports system clock frequencies up to 125 MHz with the -4 speed grade, and includes 6,144 bits of embedded memory.

FLEX 10K is the first family to combine the high density of gate arrays with the programmability of FPGAs, integrating a sea-of-gates architecture called FastTrack Interconnect that delivers predictable, fixed interconnect delays regardless of routing density. The device family introduced the concept of embedded array blocks (EABs) used for memory and arithmetic functions, which became the architectural foundation for later Altera Stratix families. The EPF10K10QC208-4N is a second-source-friendly 5 V logic part that maps cleanly into industrial and legacy telecom/industrial designs.

Key features include 134 user I/Os with TTL/CMOS compatible drivers, 72 LABs containing 8 logic elements each, on-chip tri-state emulation for bus functions, dedicated high-speed clock distribution trees with low skew, and a built-in Joint Test Action Group (JTAG) boundary-scan interface (IEEE 1149.1). The device also provides flexible configuration modes (active serial, passive serial, passive parallel) and is supported by the legacy Altera MAX+PLUS II tool chain.

The architecture separates logic (LABs) from interconnect (FastTrack rows/columns), giving designers predictable timing closure on legacy 5 V designs. Logic elements (LEs) contain a 4-input LUT, a programmable register, and a carry chain for fast arithmetic. EABs provide RAM/ROM and arithmetic functions, eliminating the need for separate memory chips in small designs. Configuration is loaded from a serial EPROM or microcontroller, supporting in-system re-programmability.

Typical applications include industrial control glue logic, telecommunications line cards, legacy 5 V microcontroller/ASIC replacement, prototype ASIC emulation, and low-density DSP pre/post-processing. The wide 5 V tolerance also makes the part a popular choice for legacy avionics, factory automation, and instrumentation that has not migrated to 3.3 V.

When designing with this FPGA, ensure that all unused I/Os are properly terminated and that the JTAG chain is correctly buffered for board-level test access. The 5 V supply and PQFP package simplify PCB layout but the 208-pin PQFP has finer pitch than modern BGAs, so careful signal integrity analysis is recommended for high-speed signals.

Ứng dụng tiêu biểu

EPF10K10QC208-4N phù hợp cho 6 Áp dụngs: Industrial Control Glue Logic, Legacy Telecom Line Card Interface, Prototype ASIC Emulation, Test & Measurement Instrumentation Front-End, Avionics / Military Legacy Subsystem, Low-Density DSP Pre/Post-Processing.

🏭

Industrial Control Glue Logic

The EPF10K10QC208-4N's 576 logic elements and 134 user I/Os are well-suited to industrial glue-logic consolidation, where multiple 74-series TTL chips are replaced by a single programmable device. The 5 V tolerance matches legacy PLC, motor-control, and process-control boards still using 5 V logic without level shifters. With 72 LABs and built-in JTAG (IEEE 1149.1), engineers can integrate address decoding, bus arbitration, and timing-pulse generation into one FPGA while keeping factory-floor test access. The PQFP-208 package is hand-solderable, simplifying low-volume retrofits and field repairs on existing 5 V industrial equipment where the supply rail cannot be changed.

🌐

Legacy Telecom Line Card Interface

In telecom line cards designed in the late 1990s, the EPF10K10QC208-4N provided 134 user I/Os to interface between T1/E1 framers, time-slot interchangers, and backplane serializers. The 125 MHz Fmax of the -4 speed grade supports 8.192 MHz PCM backplane buses and TDM framing at standard telecom rates. Its 5 V I/O directly drives TTL-level backplanes used in central-office equipment. Embedded 6,144 bits of memory implement small elastic stores and pattern detectors without external SRAM. Engineers can drop this FPGA onto existing 5 V line-card PCBs while maintaining the legacy framing protocol and JTAG in-system test infrastructure familiar to telco field technicians.

🖥️

Prototype ASIC Emulation

The EPF10K10QC208-4N was widely used as a multi-chip ASIC emulator during early product development because its 10K-gate density and SRAM-based configuration allowed rapid design iteration. Each LE contains a 4-input LUT and a programmable register, faithfully modelling gate-array timing. FastTrack Interconnect gives predictable delays independent of routing, helping engineers verify timing closure before committing to an ASIC. The 5 V core and TTL I/Os emulate target ASIC behavior with minimal external circuitry, and the PQFP-208 footprint fits standard prototype sockets. Once the design stabilizes, the bitstream can be ported to a production ASIC fab with confidence, making the EPF10K10 a classic development-platform choice.

🔧

Test & Measurement Instrumentation Front-End

Test equipment manufacturers chose the EPF10K10QC208-4N for instrument front-ends requiring precise timing control: pattern generators, logic analyzers, and frequency counters. The 125 MHz internal clock drives counter chains and timing comparators at sub-nanosecond resolution when paired with external high-speed comparators. The 134 I/Os handle parallel probe-channel multiplexing, and on-chip EABs implement small look-up tables for measurement calibration curves. The 5 V analog-friendly I/O is also tolerant of legacy probe-conditioning circuits. JTAG boundary-scan simplifies board-level test of populated instruments, and the legacy MAX+PLUS II tool chain preserves long-term design IP for service continuity.

✈️

Avionics / Military Legacy Subsystem

Avionics and military subsystems built in the 1990s-2000s used the EPF10K10QC208-4N because its 5 V supply, PQFP package, and proven SRAM architecture met DO-254 design assurance objectives for many low-criticality functions. The device handles non-volatile configuration via companion configuration PROMs, allowing cold-start boot in cockpit displays, mission computers, and ground-support equipment. 134 I/Os interface legacy ARINC 429 / MIL-STD-1553 transceivers, and on-chip memory buffers small command/response frames. The package's PQFP format remains hand-reworkable by depot-level maintenance crews, an advantage when field-replaceable units are 20+ years old and not yet scheduled for modernization.

📺

Low-Density DSP Pre/Post-Processing

The EPF10K10QC208-4N's 72 LABs and 6,144-bit EAB memory fit small DSP pre- and post-processing tasks: FIR filter coefficient multiplication, FFT butterfly staging, or sample-rate conversion stages feeding a dedicated DSP chip. The -4 speed grade's 125 MHz Fmax supports 16-tap FIR filters at 8 MHz sample rate. EABs serve as coefficient ROM and circular delay-line memory, eliminating external SRAM in compact designs. With 5 V I/O and the PQFP-208 footprint, the FPGA bridges legacy 5 V analog front-ends to modern DSP ASICs or microcontrollers without voltage translation. Designers can prototype signal chains in MAX+PLUS II then port to a fixed ASIC once volume justifies mask costs.

What is the operating frequency of EPF10K10QC208-4N?
The EPF10K10QC208-4N, speed grade -4, supports a maximum system clock frequency of 125 MHz per the FLEX 10K datasheet. Frequency depends on the design's critical path and logic utilization; this part targets legacy 5 V designs rather than modern high-speed serial interfaces.
What is the difference between EPF10K10QC208-4N and EPF10K10QC208-4?
The EPF10K10QC208-4N is the lead-free / RoHS-compliant variant of the EPF10K10QC208-4, sharing the same 208-pin PQFP package, 576 logic elements, and -4 speed grade. The 'N' suffix specifically denotes a lead-free terminal finish per Intel/Altera naming conventions; functionally the two parts are drop-in compatible.
What is the difference between EPF10K10QC208-4N and EPF10K10QC208-3?
Both parts share the same 208-pin PQFP package and 576 logic elements, but the EPF10K10QC208-3 is the slower -3 speed grade while the EPF10K10QC208-4N is the faster -4 grade. The -4 offers higher Fmax at the same 5 V supply. They are pin-compatible drop-in replacements; the -4 can be used where the -3 was specified with a speed margin.

Where to buy EPF10K10QC208-4N online?
The EPF10K10QC208-4N can be sourced from authorized distributors including DigiKey, Mouser, Arrow, and Avnet, plus brokers such as Octopart-listed vendors. As of 2026-09-11, lead time varies because the part is approaching end-of-life; XAIPART and specialty distributors carry inventory. Always verify the part number suffix when ordering - the 'N' suffix denotes lead-free finish.
What is the price of EPF10K10QC208-4N?
As of 2026-09-11, the EPF10K10QC208-4N prices on Octopart and DigiKey range from approximately $32.50 at qty 1 to $16.20 at qty 1000 based on distributor listings. Pricing has risen because Intel has been migrating FLEX 10K designs to Cyclone and MAX families, limiting supply. Quoted prices include the standard 5 V / 208-PQFP configuration with lead-free finish.
What is the lead time for EPF10K10QC208-4N?
Lead time for the EPF10K10QC208-4N as of 2026-09-11 is typically 6-12 weeks for factory-direct orders and shorter from authorized distributor stock. Because the part is in NNRD/EOL transition, broker inventory is also active with shorter lead times but at higher unit pricing. Engineers should confirm lifecycle status with the local Intel FPGA representative before placing volume orders.
Is the EPF10K10QC208-4N in stock?
Stock levels for the EPF10K10QC208-4N fluctuate because the part is in NNRD status. As of 2026-09-11, DigiKey shows limited stock and Mouser lists it by quote. Contacting 3-5 distributors and listing part on a shortage service (FindChips, Octopart) is the recommended approach for procurement teams. New factory orders must go through Intel's last-time-buy window when announced.
What is the best drop-in replacement for EPF10K10QC208-4N?
The best drop-in replacement for the EPF10K10QC208-4N is the EPF10K10QC208-3 (same 208-pin PQFP package, 576 logic elements, lower speed grade -3 vs -4). Both are pin-compatible within the FLEX 10K family. If the design has timing margin, the -3 part is a true drop-in. If higher performance is needed, the EPF10K10QC208-4 (non-N, leaded) may also be considered.
Can EPF10K10QC208-4N be replaced by a Cyclone or MAX device?
Cyclone and MAX series devices from Intel / Altera are NOT drop-in replacements for the EPF10K10QC208-4N because they use different packages (BGA, TQFP) and operate from 3.3 V or lower, not 5 V. They are functional equivalents but require PCB redesign, voltage-rail rework, and full re-implementation of the FLEX 10K design in the Quartus tool chain. They are not pin-compatible drop-ins.
Is the EPF10K10QC208-4N suitable for new designs in 2026?
The EPF10K10QC208-4N is NOT recommended for new designs in 2026 because Intel has placed the FLEX 10K family in NNRD/EOL transition. New designs should target the MAX 10 or Cyclone 10 LP families, which use modern 3.3 V / 1.8 V cores, offer more logic, and are actively supported by Quartus Prime. The EPF10K10QC208-4N should only be specified when maintaining legacy 5 V equipment.
What is the package of EPF10K10QC208-4N?
The EPF10K10QC208-4N is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package, also described as 208-BFQFP by DigiKey. The 'QC' in the part number is Altera's package code for the 208-pin PQFP. Lead pitch is 0.5 mm and the body is approximately 28 mm × 28 mm with a 5 V supply requirement - the legacy through-hole-friendly SMD form factor for industrial designs.
What are the key specifications of EPF10K10QC208-4N that engineers should know?
The EPF10K10QC208-4N key specifications are: 576 logic elements / 10,000 gates, 72 LABs, 6,144 bits embedded memory, 134 user I/Os, 125 MHz max operating frequency at speed grade -4, 5 V single supply, 0.42 µm CMOS SRAM process, 208-pin PQFP package, SRAM-based serial/parallel configuration, and IEEE 1149.1 JTAG support. These define the part's role as a legacy 5 V industrial FPGA.
What is the best Intel equivalent for EPF10K10QC208-4N from a different brand?
Cross-brand equivalents to the EPF10K10QC208-4N are limited because FLEX 10K is Altera-proprietary architecture with no second-source at the silicon level. The closest functional equivalents from other vendors are Xilinx XC9500XL family CPLDs (similar logic density, 5 V tolerance, JTAG support) and Lattice ispMACH 4000 series. None are drop-in pin-compatible; PCB redesign is required.

Dữ liệu tham khảo kỹ thuật cho EPF10K10QC208-4N — so sánh, hướng dẫn thiết kế và thông tin tuân thủ.

Hướng dẫn chọn lựa

Choose the EPF10K10QC208-4N when maintaining a legacy 5 V design that requires the highest speed grade (-4) within the FLEX 10K family, in the 208-pin PQFP package, with lead-free RoHS-compliant terminal finish. It is the best match for legacy telecom line cards, industrial control glue logic, and avionics subsystems that already target MAX+PLUS II bitstreams. If your design does not need -4 speed-grade timing margin, the EPF10K10QC208-3 (same package, 576 LE) is a lower-cost pin-compatible alternative. For non-RoHS designs or where leaded finish is acceptable, the EPF10K10QC208-4 (without 'N') is drop-in equivalent. For newer silicon revisions, consider EPF10K10AQC208-3N but verify that any existing bitstream files still meet timing closure under the A-prefix silicon characterization.

Ghi chú thiết kế

The EPF10K10QC208-4N requires a clean 5.0 V ±5% supply on VCCINT and VCCIO rails. Estimated core current draw is approximately 100-300 mA active at 125 MHz depending on logic utilization. Decoupling: place one 0.1 µF ceramic capacitor within 5 mm of every VCC pin and bulk 47-100 µF tantalum at the regulator output. SRAM-based configuration means inrush currents during configuration can spike to 500 mA momentarily; ensure regulator has adequate transient response. The 5 V I/O is TTL-compatible but exceeding 5.5 V absolute maximum permanently damages the device - add TVS diodes on board-edge connectors.

The 208-pin PQFP package has 0.5 mm lead pitch and 28 mm × 28 mm body. Recommended footprint: 0.30 mm wide pads with 0.10 mm solder mask dam. Trace escape: use 0.15 mm/0.20 mm traces fanning out from inner pads. For high-speed signals, maintain 50 Ω controlled impedance with reference plane on layer 2. The PQFP package does not have an exposed pad - thermal dissipation is through peripheral leads and copper pours on top/bottom layers. Estimated: at 0.5 W dissipation with 1 square inch copper pour, junction-to-ambient resistance is approximately 35-45 C/W.

Common pitfalls with the EPF10K10QC208-4N: (1) configuration PROMs are required - the device is SRAM-based and loses configuration on power-down; use EPC2 or EPC1 series configuration PROMs in standard FLEX 10K reference schematics. (2) JTAG chain must include proper buffering for board-level test access. (3) The MAX+PLUS II tool chain is legacy - design bitstreams generated by MAX+PLUS II may not load into Quartus-targeted configuration memory. (4) Mixing -3, -4, and A-prefix silicon in the same design works but bitstream timing files should be regenerated for the exact speed grade. (5) PQFP leads are fragile - use proper re-work profiles (220C peak for lead-free, 240C max dwell time).

Signal integrity layout notes: keep dedicated clock pins (CLK0/CLK1/CLK2) traces short and routed away from I/O switching signals; the FLEX 10K has dedicated low-skew clock distribution trees that are most effective when fed by clean clocks. Configuration signals (DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE) should be routed as a bus to keep skew below 2 ns; longer traces can cause configuration failures. JTAG signals (TCK, TMS, TDI, TDO) require 10-100 kΩ pull-ups on TMS, TDI, nCONFIG for reliable boundary-scan operation. Bank VCCIO pins may all be tied together at 5 V or split per bank; FLEX 10K allows mixed-voltage I/O but only on a per-bank basis.
