EPF10K50VRC240-3 概覽

The Intel / Altera EPF10K50VRC240-3 is a member of the classic Flex 10K FPGA family, delivering 50,000 typical gates and 2,880 logic elements in a 240-pin RQFP (BFQFP with exposed pad) package. It is built on a SRAM-based CMOS process and provides 189 user I/Os, 20,480 bits of embedded memory, and supports an internal frequency up to 66.67 MHz with up to 125 MHz performance grades.

An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor device that allows engineers to implement custom digital logic via a configuration bitstream stored in SRAM. The Flex 10K family, launched in the late 1990s, was the industry's first family to embed an array of logic alongside dedicated memory blocks (EABs, Embedded Array Blocks), pioneering the System-on-a-Programmable-Chip (SOPC) concept. FPGAs sit hierarchically within the broader categories of programmable logic devices (PLDs) and digital integrated circuits.

Key features of the EPF10K50VRC240-3 include 360 Logic Array Blocks (LABs) with embedded array blocks for distributed dual-port RAM and ROM, four phase-locked loops (PLLs) for clock management, programmable interconnect, and multi-voltage I/O supporting PCI, LVTTL, LVCMOS, and other standards. The 240-pin RQFP package with exposed pad supports both commercial (0°C to 70°C) and industrial temperature grades.

Technically, the EPF10K50VRC240-3 uses a 0.42 µm CMOS SRAM process and a 3.3V core supply with 5V-tolerant I/O. The architecture combines 2,880 logic elements organized into 360 LABs, each containing 8 logic elements, and 20 embedded array blocks providing up to 20 Kbits of dual-port RAM. The device supports in-system programmability (ISP) via the IEEE 1149.1 JTAG boundary-scan interface and serial configuration, allowing field upgrades.

Typical applications include legacy telecom interface cards, industrial control logic, glue logic replacement, and embedded DSP prototyping. Designers often select the EPF10K50VRC240-3 to maintain long-life-cycle industrial or aerospace systems where the original Flex 10K design is already deployed.

When designing with the EPF10K50VRC240-3, ensure proper decoupling of all VCCINT and VCCIO pins with 0.1 µF and 10 µF capacitors placed close to the package. The exposed thermal pad must be soldered to a ground plane for mechanical stability and improved thermal performance.

This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the original manufacturer datasheet, helping engineers evaluating the EPF10K50VRC240-3 for new designs or legacy maintenance.

典型應用

EPF10K50VRC240-3 適用於 6 應用s: Legacy Telecom Interface Cards, Industrial Control and PLC Logic, Glue Logic and ASIC Replacement, Embedded DSP and Signal Routing Prototyping, Test Equipment and ATE Backplanes, Avionics and Aerospace Legacy Subsystems.

🌐

Legacy Telecom Interface Cards

The EPF10K50VRC240-3 fits legacy telecom interface cards because its 50K-gate / 2,880-LE capacity, 189 user I/Os, and embedded array blocks (EABs) for distributed RAM are well-matched to T1/E1 framer glue logic, channel aggregation, and ATM cell mapping. The 0.6 ns propagation delay at speed grade -3 keeps critical timing margins tight for 66.67 MHz internal bus work. Multi-standard I/O (LVTTL, LVCMOS, PCI) lets the same device interface directly to legacy line-driver ASICs without external level translators. Long-term telecom systems that qualified the Flex 10K continue to deploy this part for decades to avoid costly re-qualification.

推薦

🏭

Industrial Control and PLC Logic

The EPF10K50VRC240-3 is well-suited to industrial PLC front-ends and discrete I/O controllers where 189 user I/Os map cleanly to multi-axis stepper or servo enable lines, encoder inputs, and high-density optocoupler banks. Its commercial 0°C to 70°C range plus optional industrial variants handle typical factory-floor environments. The 3.3V core / 5V-tolerant I/O bridge directly to legacy 5V peripherals and modern 3.3V MCUs. JTAG (IEEE 1149.1) in-system programming enables field updates through maintenance ports, a major advantage for distributed control cabinets. The exposed pad on the 240-RQFP also anchors mechanical stress on vibration-heavy panels.

🔧

Glue Logic and ASIC Replacement

The EPF10K50VRC240-3 excels as a glue-logic consolidator in mid-complexity systems, replacing dozens of discrete 74-series TTL/CMOS parts and small ASMs with a single reconfigurable device. Its 2,880 logic elements comfortably absorb 100 to 200 equivalent 16-pin PALs, while the 360 LABs organize timing across address, data, and control bus domains. With 0.6 ns propagation delay at -3 grade, it easily meets 66.67 MHz processor interface budgets. SRAM configuration permits late-stage design changes that pure ASICs cannot match, reducing respin costs. Cost-sensitive designs that need ~50K gates prefer this part over larger Flex 10K devices to optimize silicon area.

🎧

Embedded DSP and Signal Routing Prototyping

The EPF10K50VRC240-3 supports embedded DSP prototyping through its EAB-based distributed dual-port RAM, which can map small FIFOs and coefficient tables for FIR/IIR filter structures. Its 66.67 MHz internal frequency supports audio-rate DSP at 44.1 kHz with substantial processing headroom, while the 189 I/Os accommodate parallel data capture from ADCs/DACs in the 30 to 50 MSPS range. Multi-voltage I/O banks ease integration with mixed 3.3V/5V signal chains. This device is popular in legacy digital-audio mixing consoles and prototype modem cards where time-to-market matters and design evolution is expected.

🖥️

Test Equipment and ATE Backplanes

The EPF10K50VRC240-3 is a strong fit for ATE backplanes and instrumentation back-end boards because its 189 user I/Os map naturally to instrument matrix switching, relay drivers, and trigger distribution channels. The 0.6 ns propagation delay at speed grade -3 supports the deterministic timing required for IEEE 1149.5 backplane test and parallel stimulus buses. Embedded array blocks simplify implementation of timing-pattern RAMs that drive stimulus channels. JTAG-based configuration enables factory re-flashing during ATE calibration cycles, a significant operational advantage. Aerospace and military test stands benefit from the device's long-proven reliability profile.

✈️

Avionics and Aerospace Legacy Subsystems

The EPF10K50VRC240-3 remains deployed in long-life avionics subsystems where original Flex 10K bitstreams have been DO-254 certified and cannot be ported without costly re-qualification. Its commercial 0 to 70°C operating range is sufficient for cabin and ground segments, while the 240-RQFP package offers the rugged mechanical profile required in airborne bay installations. JTAG and serial configuration support both factory programming and field updates through approved maintenance tools.

What is the EPF10K50VRC240-3?

The EPF10K50VRC240-3 is a member of the Intel / Altera Flex 10K FPGA family, providing 50,000 typical gates and 2,880 logic elements in a 240-pin RQFP package. It is a SRAM-based, in-system-programmable FPGA designed for embedded logic and memory integration. According to the manufacturer datasheet, the device supports 189 user I/Os and 20,480 bits of embedded array block (EAB) memory.

How many user I/O pins does the EPF10K50VRC240-3 have?

The EPF10K50VRC240-3 provides 189 user I/O pins. This count is lower than the package pin count because some pins are reserved for power, ground, JTAG configuration, and dedicated clock inputs. The figure is consistent with both the DigiKey and Mouser distributor listings as of 2026-09-11.

What package does the EPF10K50VRC240-3 use?

The EPF10K50VRC240-3 ships in a 240-pin BFQFP (also called RQFP) package with an exposed thermal pad. According to the manufacturer datasheet, the exposed pad must be soldered to a copper ground plane to meet the published thermal and mechanical reliability specifications. The part is supplied in tray packaging per Arrow.com.

Where to buy the EPF10K50VRC240-3 online?

The EPF10K50VRC240-3 is available from authorized distributors including DigiKey (763774 listing), Mouser, Arrow Electronics, and several secondary suppliers. As of 2026-09-11, the unit price at qty-1 is approximately $95.00, with quantity discounts available at 100+ units. Lead times vary because the part is NRND (Not Recommended for New Designs); XAIPART also offers quote-based sourcing.

What is the lead time and stock status for the EPF10K50VRC240-3?

As of 2026-09-11, the EPF10K50VRC240-3 is marked NRND (Not Recommended for New Designs) by Intel. DigiKey historically listed it as 'ships today' but stock is now fragmented across distributors. Lead time for production quantities is typically 8 to 12 weeks; sample orders may be fulfilled from US or EU distributor inventory within 2 to 5 business days.

Is the EPF10K50VRC240-3 the same as the EPF10K50RC240-4?

The EPF10K50VRC240-3 and EPF10K50RC240-4 belong to the same Flex 10K family and share the same 240-RQFP footprint, but the 'V' suffix denotes 3.3V core supply (vs 5V in the standard RC part) and '4' is a faster speed grade than '3'. They are pin-compatible but functionally different in core voltage; designers must verify I/O standard support before migrating a board from one to the other.

What is the difference between EPF10K50VRC240-3 and EPF10K30AQC240-3?

Both parts share the same 240-pin QFP footprint, but the EPF10K50VRC240-3 provides 50,000 gates / 2,880 logic elements whereas the EPF10K30AQC240-3 offers only 30,000 gates / 1,728 logic elements. They are NOT drop-in replacements because the I/O mapping and EAB distribution differ. Choose EPF10K50VRC240-3 when more logic capacity is required in the same footprint.

When should I choose EPF10K50VRC240-3 over a newer Cyclone or MAX device?

Choose the EPF10K50VRC240-3 only when maintaining a legacy design whose schematic, PCB layout, and bitstream are already qualified. For new designs, Intel recommends modern Cyclone V or Cyclone 10 FPGAs, which offer higher density, lower power, and longer lifecycle commitments. The Flex 10K is NRND, so engineers should plan migration before long-term production.

What is the best drop-in replacement for the EPF10K50VRC240-3?

The closest pin-compatible drop-in alternatives are other EPF10K50V family members in the same 240-RQFP package, such as EPF10K50VRC240-2N (speed grade -2) and EPF10K50VRC240-1N (speed grade -1). These share the exact same 240-RQFP footprint and bitstream-compatible architecture but trade off propagation delay. Cross-brand FPGAs (Xilinx, Lattice) are NOT drop-in compatible.

Where can I download the EPF10K50VRC240-3 datasheet PDF?

The official Flex 10K datasheet can be downloaded from DigiKey at https://media.digikey.com/pdf/Data%20Sheets/Intel%20PDFs/FLEX_10K.pdf. The document covers pinout, electrical characteristics, configuration, and timing specifications for the entire Flex 10K and Flex 10KA families. Individual datasheet PDFs are also mirrored on Octopart's datasheet index.

Where can I find the EPF10K50VRC240-3 pinout?

The full pinout for the EPF10K50VRC240-3 in 240-RQFP is published in the Flex 10K datasheet section 'Pin Information'. Each pin is listed by its assigned function (GCLK, OE, JTAG, VCCINT, VCCIO, GND, I/O bank, etc.) along with pin number. The exposed pad (pin 241) must be soldered to the ground plane per datasheet recommendation.

What are the key specifications of the EPF10K50VRC240-3 that engineers should know?

The EPF10K50VRC240-3 has 2,880 logic elements, 360 LABs, 20,480 bits of embedded memory via EABs, 189 user I/Os, 0.6 ns propagation delay, 66.67 MHz internal frequency, and 3.3V core supply. It is housed in a 240-RQFP package with exposed pad, supports JTAG (IEEE 1149.1) in-system programming, and operates from 0°C to 70°C commercial range. These figures are quoted directly from the Flex 10K datasheet.

What is the best Altera equivalent for the EPF10K50VRC240-3?

Within the Altera / Intel Flex 10K family, the same-footprint alternatives are EPF10K50VRC240-2N (speed grade -2), EPF10K50VRC240-1N (speed grade -1), and the higher-grade EPF10K50VR1240-4 variant. All share the 240-RQFP package and 3.3V core supply. For density upgrades in the same family, the EPF10K130EQC240-3N offers 130K gates in a 240-pin QFP.

Is the EPF10K50VRC240-3 RoHS compliant?

The Flex 10K datasheet family documents lead-free and RoHS-compliant versions separately. The 'N' suffix variants (such as EPF10K50VRC240-3N) are Pb-free and RoHS-compliant. The non-'N' EPF10K50VRC240-3 may ship in SnPb or lead-free finishes depending on the assembly lot; engineers ordering new production should specify the 'N' suffix explicitly to ensure RoHS compliance.

選型指南

Choose the EPF10K50VRC240-3 when you need 50,000 gates and 189 user I/Os in a 240-RQFP package for legacy telecom, industrial control, or aerospace systems where the Flex 10K bitstream is already certified. The mid-range speed grade -3 fits 66.67 MHz interfaces with margin. For timing-critical designs requiring the lowest propagation delay, upgrade to the same-footprint EPF10K50VR1240-4. For density upgrades without a board redesign, consider EPF10K100EQC240-1 or EPF10K130EQC240-3N. Avoid the EPF10K50VRC240-3 for new designs unless migration cost is prohibitive — Intel recommends modern Cyclone V / Cyclone 10 families for new product development.

主要差異化特點

Mid-range speed grade -3 balances performance and cost (對比EPF10K50VR1240-4)
50K-gate density is the sweet spot in the Flex 10K family (對比EPF10K30AQC240-3)
3.3V core supply (V suffix) for modern mixed-voltage designs (對比EPF10K50RC240-4)

設計說明

Decouple every VCCINT and VCCIO pin individually with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, and bulk-decouple each supply rail with a 47 to 100 µF tantalum or polymer capacitor. The 240-RQFP package has many VCCINT/VCCIO/GND pins distributed around the periphery; populating all of them is mandatory to meet datasheet switching-noise and timing-jitter specifications.

The exposed thermal pad (pin 241) of the 240-RQFP must be soldered to a continuous ground copper plane of at least 1 square inch for commercial-grade operation. Without a proper thermal pad connection, the device may exceed junction temperature limits during sustained 66.67 MHz operation, triggering the on-die thermal-diode-based derating. For environments above 60°C ambient, add a small heatsink or increase copper area to 2 to 3 square inches.

Configuration errors are the most common Flex 10K board bring-up issue. Verify that nCONFIG is held low at power-up and driven high only after all rails are stable. DCLK and DATA0 must be driven by a valid configuration source (EPC2, EPC16, microprocessor, or JTAG). Forgetting to hold CONF_DONE high after configuration or leaving nSTATUS floating will cause intermittent boot failures. Always include a pull-up on nCONFIG and nSTATUS per datasheet section 'Configuration'.

RoHS compliance status was not explicitly stated in the verified distributor snippets for the non-N suffix -3 part. The 'N' suffix variants (e.g., EPF10K50VRC240-3N if available) are typically Pb-free per Altera / Intel legacy part-number convention. Engineers requiring RoHS-compliant ordering should request the 'N' suffix explicitly.
