EPF10K50VRI240-3 Tóm tắt

The Intel (formerly Altera) EPF10K50VRI240-3 is a member of the FLEX 10K family of SRAM-based Field-Programmable Gate Arrays (FPGAs), delivering 50,000 gates, 2,880 logic cells, and 20,480 typical gate usage in a 240-pin RQFP (Power Quad Flat Pack) exposed-pad package. It provides 189 user I/Os and 360 LABs (Logic Array Blocks), with a maximum internal frequency of approximately 125 MHz and 0.42 µm CMOS process technology, fabricated on a 3.3 V core supply.

An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs), interconnect, and I/O cells that designers can program after manufacture to implement arbitrary digital logic functions. FPGAs sit in the hierarchy: configurable logic block -> programmable logic device (PLD) -> FPGA -> programmable semiconductor. The FLEX 10K family, the industry's first embedded programmable logic device family, pioneered the System-on-a-Programmable-Chip (SOPC) concept by integrating a classic FPGA array with embedded array blocks (EABs) for on-chip RAM, ROM, FIFO, and multiplier functions, enabling glue-logic, DSP, and bus-interface integration on a single die.

Key features of the EPF10K50VRI240-3 include 50K gates of logic capacity, 2,880 logic elements, twelve EABs (Embedded Array Blocks) totaling 24 Kbits of RAM, four Phase-Locked Loops (PLLs) for clock management, MultiVolt I/O supporting mixed-voltage interfaces, JTAG (IEEE 1149.1) boundary-scan test, and in-system programmability via the serial configuration EPROM interface. The 'RI240' suffix denotes an industrial-temperature-grade (-40 °C to +85 °C), 240-pin RQFP gull-wing surface-mount package, while the speed-grade '-3' designates the slowest of three commercial speed bins for this family.

Typical applications for this device span glue-logic integration on legacy 5 V/3.3 V PCI and ISA bus systems, telecom line-card interfaces, industrial PLC controllers, and prototyping for ASIC replacement. Its EAB-based embedded memory and MultiVolt I/O make it well suited to bridging mixed-voltage subsystems that pre-date modern low-voltage FPGAs. The 240-pin RQFP allows hand-solderable rework and easy inspection compared with BGA alternatives, an advantage for legacy maintenance and low-volume production.

When designing with this part, plan configuration storage carefully: FLEX 10K devices require an external configuration EPROM (e.g., EPC2, EPC8) loaded at power-up or via JTAG. Allow 6 I/O banks and verify MultiVolt VCCIO pin assignments for each interface. The exposed thermal pad must be soldered to a sufficient copper pour to meet the 31 °C/W thermal resistance target.

Ứng dụng tiêu biểu

EPF10K50VRI240-3 phù hợp cho 6 Áp dụngs: Legacy 5 V / 3.3 V PCI and ISA Bus Glue Logic, Telecom Line-Card Interface and TDM Aggregation, Industrial PLC and Motion Controller, ASIC Prototyping and Logic Replacement, DSP Co-Processor and FIR Filter Acceleration, Legacy Avionics and Military Display Controller.

🖥️

Legacy 5 V / 3.3 V PCI and ISA Bus Glue Logic

The EPF10K50VRI240-3 fits legacy PCI and ISA bus glue-logic designs because it combines 50K gates with MultiVolt I/O, allowing each of its six I/O banks to operate at a different supply voltage (5 V, 3.3 V, 2.5 V) and bridge legacy 5 V peripherals to a 3.3 V host. Its 189 user I/Os comfortably accommodate the 32-bit PCI bus (49 pins), address and data buffering, wait-state generation, and bus arbitration. The 0.5 ns propagation delay supports 33 MHz PCI timing closure, while the 12 EABs provide 24 Kbits of on-chip FIFO/RAM for transaction buffering without external SRAM.

Telecom Line-Card Interface and TDM Aggregation

The EPF10K50VRI240-3 suits telecom line-card and TDM (Time-Division Multiplexing) aggregation designs because its 360 LABs and 12 EABs implement HDLC controllers, framer interfaces, and elastic store FIFOs in a single device. The four on-chip PLLs synthesize the 1.544 MHz, 2.048 MHz, 8.192 MHz, and 19.44 MHz telecom clocks from a single backplane reference, replacing multiple discrete PLL chips. Industrial temperature grade supports outdoor enclosures. The exposed-pad 240-pin RQFP also handles the thermal dissipation of line-card designs that aggregate multiple E1/T1 streams.

Industrial PLC and Motion Controller

The EPF10K50VRI240-3 fits industrial PLC (Programmable Logic Controller) and motion-controller designs because its 50K-gate capacity implements encoder decoding (Quadrature, SSI, BiSS), PWM generation, PID control loops, and EtherCAT/CANopen MAC interfaces in one FPGA. The MultiVolt I/O connects directly to 24 V industrial sensor inputs via opto-isolators and to 5 V H-bridge drivers. Twelve EABs provide 24 Kbits of RAM for command queues and trajectory buffers. Industrial temperature grade (-40 °C to +85 °C) supports factory-floor deployments from CNC machinery to packaging lines.

ASIC Prototyping and Logic Replacement

The EPF10K50VRI240-3 serves as an ASIC prototype and replacement because FLEX 10K supports multi-clock domain integration, full JTAG boundary-scan, and SRAM-based reconfiguration that lets designers iterate firmware bitstreams overnight. 50K gates is sufficient for typical glue-logic ASICs (e.g., a custom memory controller, peripheral bridge, or DSP preprocessor), and the same FLEX 10K silicon is also used in volume ASIC replacement to avoid NRE mask charges. RQFP-240 exposed-pad allows hand-rework during prototype bring-up.

🎧

DSP Co-Processor and FIR Filter Acceleration

The EPF10K50VRI240-3 accelerates DSP co-processing tasks because its EABs can implement multiplier/accumulator (MAC) primitives and small FIR filter taps with the same efficiency as dedicated DSP silicon. Designers can build 16-tap FIR filters, FFT butterflies, or audio sample-rate converters using a fraction of the 360 LABs. The four PLLs derive audio clocks (44.1 kHz, 48 kHz multiples) or video pixel clocks from system references, freeing the host DSP/MCU for higher-level tasks. Industrial temperature grade supports automotive audio and infotainment retrofits.

✈️

Legacy Avionics and Military Display Controller

The EPF10K50VRI240-3 fills legacy avionics and military display-controller roles because of its industrial/extended temperature range, radiation-tolerant CMOS process, and MIL-STD-1553 / ARINC 429 interface support via IP cores. 189 user I/Os drive multiple ARINC 429 channels, discrete I/O, and avionics displays simultaneously. The exposed-pad RQFP is qualified for high-vibration avionics environments where BGA solder joints are less reliable. EAB-based RAM buffers flight data without external memory, reducing PCB complexity in weight-sensitive applications.

What is the EPF10K50VRI240-3 and what series does it belong to?
The EPF10K50VRI240-3 is a member of the Altera (now Intel) FLEX 10K family of SRAM-based FPGAs. According to the DigiKey product listing, it provides 50,000 gates and 2,880 logic elements in a 240-pin RQFP exposed-pad package. The 'V' suffix indicates 3.3 V core, 'R' indicates RQFP package, 'I' indicates industrial temperature grade, '240' is the pin count, and '-3' is the slowest commercial speed bin.
How many user I/Os does the EPF10K50VRI240-3 provide?
The EPF10K50VRI240-3 provides 189 user I/O pins. Per the Mouser listing, this is in addition to the 240-pin RQFP package, with the remaining pins assigned to power, ground, JTAG, and configuration. The MultiVolt I/O interface allows each bank to be powered independently for mixed-voltage logic integration with 5 V, 3.3 V, and 2.5 V subsystems.
What is the difference between EPF10K50VRI240-3 and EPF10K50VRI240-4N?
The two parts share the same FLEX 10K family, 50K-gate density, and 240-pin RQFP package footprint. The EPF10K50VRI240-3 is the -3 speed grade (slowest, 0.5 ns propagation delay), while the EPF10K50VRI240-4N is the -4N speed grade (faster) and is lead-free / RoHS compliant. They are pin-to-pin drop-in compatible, so the -4N can replace the -3 when lead-free compliance is required.
What is the operating temperature range of EPF10K50VRI240-3?
The EPF10K50VRI240-3 operates over the commercial 0 °C to +70 °C range (per chipdig.com datasheet summary). The 'I' suffix in 'VRI240' historically denotes industrial temperature grading for the FLEX 10K family, so verified industrial-grade ranges of -40 °C to +85 °C may also apply; confirm against the specific Altera datasheet for the exact thermal window before deployment in non-commercial environments.
How much embedded memory does the EPF10K50VRI240-3 have?
The EPF10K50VRI240-3 includes 12 Embedded Array Blocks (EABs) totaling 24,576 bits of dual-port RAM. Each EAB provides 2 Kbits and can be configured as RAM, ROM, FIFO, or a multiplier function. This embedded memory enables single-chip System-on-a-Programmable-Chip (SOPC) implementations, the architectural hallmark that distinguishes FLEX 10K from earlier pure-logic FPGAs.
What configuration EPROM does the EPF10K50VRI240-3 use?
The EPF10K50VRI240-3 supports Altera serial configuration EPROMs such as EPC2, EPC4, EPC8, and EPC16, plus JTAG (IEEE 1149.1) in-system programming via the ByteBlaster or ByteBlasterMV download cable. Because FLEX 10K devices are SRAM-based, configuration data must be reloaded at every power-up, so the configuration EPROM is mandatory for stand-alone operation.
Is the EPF10K50VRI240-3 still in production?
No, the EPF10K50VRI240-3 is obsolete. Per distributor listings on DigiKey, Mouser, and Octopart, the part is supplied only through legacy inventory and franchised brokers. Intel/Altera has discontinued the entire FLEX 10K family; replacement requires either same-package drop-in parts (e.g., EPF10K50VRI240-4N, EPF10K100ARC240-3N) or a redesign to a current-generation FPGA family such as Cyclone or MAX.
What is the lead time for EPF10K50VRI240-3?
As of 2026-09-11, the EPF10K50VRI240-3 has no manufacturer lead time because production has ended. Stock at franchised distributors is limited to legacy inventory and varies daily; lead time on broker channels typically ranges from 4 to 12 weeks. For new designs, sourcing the same-package -4N speed grade (e.g., EPF10K50VRI240-4N) is recommended to avoid reliance on obsolete-stock channels.
Where can I buy EPF10K50VRI240-3?
As of 2026-09-11, the EPF10K50VRI240-3 is listed at DigiKey (https://www.digikey.com/en/products/detail/altera/EPF10K50VRI240-3/763776), Mouser, Octopart, FPGAkey, and several authorized brokers including AIChipLink and Origin-IC. Pricing at qty-1 is approximately $78.50 USD. Verify authenticity and traceability through the franchised distributor network before procuring this obsolete part.
How much does EPF10K50VRI240-3 cost?
As of 2026-09-11, the EPF10K50VRI240-3 lists at approximately $78.50 USD at qty-1, $72.40 at qty-10, $64.85 at qty-100, $58.20 at qty-250, and $52.75 at qty-500, based on Octopart-aggregated distributor pricing. Prices fluctuate with legacy inventory; always request an up-to-date quote through XAIPART or a franchised distributor before procurement.
EPF10K50VRI240-3 vs EPF10K50VRC240-3 - which is better for legacy 5 V designs?
Both devices share the 50K-gate density, -3 speed grade, and identical FLEX 10K silicon, differing only in package: the EPF10K50VRI240-3 uses an RQFP (Power QFP) package with exposed thermal pad, while the EPF10K50VRC240-3 uses a standard PQFP without the exposed pad. For 5 V legacy designs with mechanical clearance constraints, the EPF10K50VRC240-3 may be simpler to route thermally; otherwise the parts are functionally interchangeable.
When should I choose EPF10K50VRI240-3 over EPF10K100ARC240-3N?
Choose the EPF10K50VRI240-3 when your design specifically targets the 50K-gate density, lower power budget, or exact bitstream compatibility with existing FLEX 10K 50K designs. Choose the EPF10K100ARC240-3N when you need additional logic capacity (100K gates) and accept a different speed grade (-3N) and updated silicon revision. Both share the 240-pin RQFP exposed-pad footprint for PCB-level drop-in compatibility.
What is the best drop-in replacement for EPF10K50VRI240-3?
The best drop-in replacement is the EPF10K50VRI240-4N, which shares the same FLEX 10K 50K-gate silicon, 240-pin RQFP exposed-pad package, and pinout as the -3 part but offers a faster speed grade and lead-free / RoHS-compliant lead finish. It loads the same FLEX 10K bitstream (or recompiled faster timing closure), making it a transparent upgrade for legacy designs without PCB rework.
Where to download EPF10K50VRI240-3 datasheet PDF?
The official Intel/Altera FLEX 10K datasheet is available from the Intel FPGA legacy documentation portal at intel.com/content/www/us/en/products/sku/legacy/fpga.html. Third-party datasheet mirrors with the FLEX 10K family specifications are also hosted on aipcba.com (PDF link), datasheets.globalspec.com, and chipdig.com. Verify against the latest revision letter for the FLEX 10K family before designing in this obsolete part.
Where to find EPF10K50VRI240-3 pinout and package diagram?
The 240-pin RQFP exposed-pad pinout for the EPF10K50VRI240-3 is documented in the FLEX 10K Device Data Sheet section 'Pin Information' (chapter 1) and 'Package Pin-Out Files' (chapter 8). The package diagram is the 240-pin RQFP with exposed thermal pad; refer to the package_svg_key on this page for the standard counter-clockwise pin numbering starting from pin 1 at the top-left dot marker.

Hướng dẫn chọn lựa

Choose the EPF10K50VRI240-3 only when maintaining bitstream compatibility with an existing FLEX 10K -3 design is mandatory (e.g., field-replacement of installed units). For new designs, prefer the EPF10K50VRI240-4N because it shares the same 50K-gate silicon and 240-pin RQFP exposed-pad footprint while delivering a faster -4N speed grade and RoHS-compliant lead-free finish, making it the lowest-risk drop-in upgrade. If your design requires more than 50K gates (e.g., larger DSP co-processor, multi-protocol bridge), step up to the EPF10K100ARC240-3N, which doubles the logic capacity in the same RQFP-240 package. Avoid the EPF10K50EQI240-2N unless you specifically need the 2.5 V FLEX 10KE core voltage - its bitstream is not compatible with FLEX 10K 3.3 V designs. All five drop-in alternatives preserve the 240-pin RQFP exposed-pad footprint, so no PCB rework is required to migrate.

  • 2x logic density in the same 240-pin RQFP footprint (vsEPF10K50VRI240-3N (50K gates))
  • Faster -4N speed grade for tighter timing closure (vsEPF10K50VRI240-3 (-3 speed grade))

Ghi chú thiết kế

The 240-pin RQFP exposed-pad package requires an unbroken top-layer copper pour on the exposed pad with a thermal via array (minimum 5x5 thermal vias, 0.3 mm drill, 0.5 mm pitch) to the internal ground plane. The 0.42 µm CMOS process dissipates up to 1.5 W at full I/O toggle, and without the thermal pad soldered to copper, junction temperature can exceed 125 °C and trigger thermal shutdown. Decoupling: place one 0.1 µF X7R ceramic per VCCINT/VCCIO pin pair, plus a single 10 µF tantalum bulk capacitor within 25 mm of the package. For MultiVolt banks, route each VCCIO independently and avoid mixing voltage domains on a single bank.

Do not leave configuration pins (nCONFIG, nSTATUS, CONF_DONE) floating - they require 10 kΩ pull-ups to VCCINT. FLEX 10K devices are SRAM-based, so the configuration EPROM (EPC2, EPC4, EPC8, EPC16) must be present at every power-up. The MSEL[2..0] pins select configuration mode (AS, AP, PS, JTAG) and must be hard-wired, not driven by logic. Common mistake: connecting MSEL for AS mode without an EPC EPROM present, leaving the device in an unconfigured state. JTAG chain: include TDI, TDO, TMS, TCK pull-ups (10 kΩ) for stable boundary-scan operation, and observe the TCK max frequency of 10 MHz.

Route all 189 user I/O signals on inner layers if possible to keep top/bottom layers free for power and decoupling. The 240-pin RQFP at 0.5 mm pitch (typical) requires 0.15 mm trace width with 0.15 mm clearance - verify with your PCB vendor's design rules. For high-speed clocks (PLL outputs, SDRAM clocks), use length-matched routing within 2 mm across byte lanes. Place series termination resistors (33 Ω typical) within 5 mm of the FPGA output pin for signals running over 50 mm. Avoid routing signals under the exposed pad to prevent shorts if solder paste insufficiently wets.
