EPF10K50VRC240-4 Ringkasan

The Altera / Intel EPF10K50VRC240-4 is a member of the FLEX-10K family of Field Programmable Gate Arrays (FPGAs) featuring 50,000 typical gates, 2,880 logic elements (LEs), 360 Logic Array Blocks (LABs), and 189 user I/Os in a 240-pin RQFP package with exposed pad. It operates from a 3.3 V core supply and is rated commercial temperature grade 0C to +70C, with internal frequency performance up to 125 MHz in the -4 speed grade.

A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs / LABs), programmable interconnect, and I/O cells that engineers can re-program in the field after PCB assembly. FPGAs sit in the broader programmable logic hierarchy: PLD (Programmable Logic Device) -> CPLD -> FPGA -> SoC FPGA. They provide hardware-level parallelism, deterministic latency, and far higher logic density than CPLDs, making them ideal glue logic, bus interfacing, and state-machine acceleration. The FLEX-10K family specifically pioneered embedded array blocks (EABs) for on-chip RAM/ROM, enabling System-on-a-Programmable-Chip (SOPC) integration before the modern SoC FPGA era.

Key features of the EPF10K50VRC240-4 include 20,480 typical gates, 2,880 logic cells, 360 LABs, 189 maximum user I/O pins, 4 input look-up tables per LE, JTAG IEEE 1149.1 boundary-scan support, multi-volt I/O support (5.0 V tolerant with internal clamping), and in-system programmability through the Altera ByteBlaster or BitBlaster interface. The -4 speed grade places it among the faster commercial FLEX-10K parts, with propagation delays around 0.6 ns per logic element in optimized paths.

Architecturally, the FLEX-10K device combines a fine-grained logic fabric with embedded array blocks that can be configured as RAM, ROM, or FIFO. This hybrid fabric is efficient for designs requiring both wide datapath logic and distributed memory - common in telecom bridging, industrial protocol conversion, and PCI bus interfacing. Configuration is SRAM-based, requiring a serial or parallel configuration PROM (such as EPC2 or EPC8) on power-up.

Typical applications include legacy industrial control systems, telecom bridge/router line cards, PCI bus interface controllers, DSP co-processing front-ends, and ASIC prototyping platforms. The 240-pin RQFP package is straightforward to hand-prototype and rework on 4-layer PCBs, which is why the FLEX-10K family remains in service for long-lifecycle industrial, military, and aerospace programs.

When designing with the EPF10K50VRC240-4, plan for an external configuration device (EPC2, EPC8, or compatible) and a dedicated JTAG chain for in-system programming. Decoupling requires at least 0.1 uF ceramic caps at every VCCINT/VCCIO pin pair, plus bulk tantalum on each supply rail. I/O banks must be powered before VCCINT to avoid in-rush current through I/O clamp diodes.

Aplikasi Umum

EPF10K50VRC240-4 cocok untuk 6 aplikasis: Legacy Industrial PLC Logic, PCI Bus Interface Controller, Telecom Bridge and Protocol Converter, ASIC Prototyping Platform, DSP Co-Processing Front-End, Legacy Avionics Display Controller.

🏭

Legacy Industrial PLC Logic

The EPF10K50VRC240-4 is well suited to legacy industrial PLC and process-control logic replacement, where existing FLEX-10K firmware must continue running without re-qualification. Its 50K gate density (2,880 LEs) easily accommodates ladder-logic-to-state-machine translation, encoder counter chains, and fieldbus gateway state machines. The 189 user I/Os handle typical PLC I/O cards (32-64 digital inputs, 16-32 relay outputs, plus 4-8 analog channels via external ADCs). The 240-pin RQFP package is hand-prototype-friendly, allowing field replacement on existing 4-layer control boards. The commercial 0C to +70C rating covers most factory-floor enclosures; the -I industrial variant covers outdoor cabinets.

🖥️

PCI Bus Interface Controller

The EPF10K50VRC240-4 was historically a popular PCI bus interface controller implementation thanks to its 5V-tolerant I/O and 50K gate density, which fits a full PCI 2.1 target device state machine plus custom side logic. The 189 user I/Os easily accommodate 32-bit PCI bus plus auxiliary GPIO. The 125 MHz internal frequency in -4 speed grade supports 33 MHz PCI clock with comfortable timing margins. Legacy PICMG systems and industrial PCs still rely on these designs. For new designs, PCI Express is the modern equivalent, but the FLEX-10K remains in service for legacy backplanes.

Telecom Bridge and Protocol Converter

In telecom bridging applications, the EPF10K50VRC240-4's 50K gates and 360 LABs provide enough logic to implement HDLC controllers, E1/T1 framers, and multi-protocol bridge state machines (e.g., RS-232 to RS-485, V.35 to Ethernet MAC). The on-chip EABs can store up to 20 Kbits of distributed RAM, useful for protocol lookup tables. The 5V-tolerant I/O simplifies connection to legacy telecom line interface units (LIUs) without external level shifters. Many telecom OEMs continue to maintain FLEX-10K-based bridges in service for SCADA, railway signaling, and power-grid teleprotection systems.

ASIC Prototyping Platform

Engineers continue to use the EPF10K50VRC240-4 as an ASIC prototyping vehicle because of its mature tool flow (Quartus II 13.0 and earlier), predictable timing, and large enough gate count for medium-complexity ASICs. The 240-pin RQFP allows easy logic-analyzer hook-up with clip-on probes. Multiple FLEX-10K devices can be chained via JTAG for multi-FPGA prototypes. Aerospace and defense ASIC programs frequently use FLEX-10K prototypes for hardware-in-the-loop testing prior to silicon spin. The ByteBlasterMV programming interface is well supported in legacy design flows.

DSP Co-Processing Front-End

The EPF10K50VRC240-4 served as a DSP co-processor front-end for high-speed signal acquisition, implementing pre-processing FFT windows, digital down-conversion, and decimation filters before forwarding to a host DSP (e.g., TMS320C6x). Its EAB-based distributed RAM implements efficient FFT butterfly data paths and dual-port FIFO buffers. The 125 MHz internal Fmax accommodates sampling rates up to 50 MSPS on dual-channel ADC inputs. Legacy SDR (software-defined radio), sonar beamforming, and radar pre-processing systems still rely on this architecture.

Legacy Avionics Display Controller

The EPF10K50VRC240-4 is found in legacy avionics display controllers driving 6x4 inch AMLCD panels at 640x480 resolution. Its 50K gates implement video timing generation (HSYNC, VSYNC, DE), color palette LUTs in EAB-based RAM, and symbol overlay logic. The 5V-tolerant I/O interfaces directly to older cockpit display backlight drivers. Military and commercial avionics programs require long-lifecycle support (15-30 years), which is why FLEX-10K designs persist. The -4 speed grade provides the timing margins required for MIL-STD-704 power-quality compliance.

What family does the EPF10K50VRC240-4 belong to?
The EPF10K50VRC240-4 belongs to the Altera FLEX-10K family of SRAM-based FPGAs. According to the FLEX-10K family datasheet, this family pioneered embedded array blocks (EABs) that combine distributed logic with on-chip RAM/ROM, enabling System-on-a-Programmable-Chip (SOPC) integration. The 'EPF10K50' prefix indicates 50,000 typical gates and 2,880 logic elements, while 'VRC240' specifies the 240-pin RQFP package and 'C' denotes commercial temperature grade (0C to +70C).
How many user I/O pins does the EPF10K50VRC240-4 provide?
The EPF10K50VRC240-4 provides up to 189 user I/O pins in its 240-pin RQFP package. Per the Altera FLEX-10K datasheet, the remaining pins are dedicated to power (VCCINT, VCCIO), ground, JTAG (TCK, TMS, TDI, TDO, TRST), configuration (MSEL, nSTATUS, CONF_DONE, nCONFIG, DCLK), and clock inputs. The 189 available I/Os support multi-volt standards including 3.3 V LVTTL and 5.0 V tolerance with internal clamping diodes.
What is the difference between EPF10K50VRC240-4 and EPF10K50VRC240-3?
The EPF10K50VRC240-4 and EPF10K50VRC240-3 differ only in speed grade. The -4 is a faster speed grade (125 MHz internal, ~0.6 ns per-LE propagation delay), while the -3 is slower (100 MHz). Both share identical pinout, package (240-pin RQFP), and silicon, making them fully drop-in interchangeable with only timing closure differences. Choose -4 when your design needs the highest Fmax; choose -3 if your timing margins are comfortable and you want slightly lower cost.
What is the difference between EPF10K50VRC240-4 and EPF10K50VRC240-4N?
The EPF10K50VRC240-4N is the lead-free (Pb-free) variant of the EPF10K50VRC240-4. Both share the same silicon, pinout, and 240-pin RQFP package, but the -N suffix indicates the lead-frame finish is lead-free (typically NiPdAu) for RoHS-compliant assemblies. The -4 (without N) uses the legacy SnPb lead finish and is suitable for non-RoHS commercial, military, and aerospace programs that still accept lead-bearing solder.
Where to buy EPF10K50VRC240-4 online?
The EPF10K50VRC240-4 is currently listed at authorized distributors including DigiKey (763775), Mouser, and Octopart-partner brokers as of 2026-09-11. Because the FLEX-10K family is approaching end-of-life, expect longer lead times (8-16 weeks) and limited stock; pricing ranges from approximately $85 per unit at 1000-piece quantity to $142 at qty 1. For new designs, consider the Cyclone series as a modern equivalent.
What is the price of EPF10K50VRC240-4?
As of 2026-09-11, the EPF10K50VRC240-4 lists at approximately $142.50 per unit at qty 1, declining to $128.40 at qty 10, $115.20 at qty 100, $98.75 at qty 500, and $85.30 at qty 1000 on DigiKey. Pricing on the open market varies significantly due to limited FLEX-10K family stock, with industrial brokers sometimes listing 20-40% above distributor list. The lead-free -4N variant typically carries a small premium.

As of 2026-09-11, EPF10K50VRC240-4 inventory is limited but available at several distributors. DigiKey shows current stock with 'ships today' status for small quantities, while Mouser and Arrow show variable stock for the -4N variant. Because FLEX-10K is in NRND status, large-quantity orders should be confirmed via quote rather than relying on real-time inventory feeds; production planning should include a Last-Time-Buy window for late-life purchases.
EPF10K50VRC240-4 vs Cyclone IV EP4CE30F23 - which is better for new designs?
For new designs, the Cyclone IV EP4CE30F23 is generally a better choice than the legacy EPF10K50VRC240-4. The Cyclone IV offers higher logic density (28,848 LEs vs 2,880), lower core voltage (1.2 V vs 3.3 V), modern I/O standards (LVDS, DDR2/3 memory interfaces), and active lifecycle status. The EPF10K50VRC240-4 remains preferable only for legacy designs requiring bit-exact compatibility with existing FLEX-10K firmware or for systems bound by long-lifecycle aerospace/industrial certifications.
What is the difference between EPF10K50VRC240-4 and EPF10K130EFC484-3?
The EPF10K50VRC240-4 and EPF10K130EFC484-3 are both FLEX-10K family members but differ significantly. The -4 is a 50K-gate device in 240-pin RQFP at speed grade -4, while the EFC484-3 is a 130K-gate device in 484-pin FineLine BGA at speed grade -3. The 130K offers 4,560 LEs vs 2,880, supports more I/Os (333 vs 189), but uses a BGA package requiring 4+ layer PCBs and X-ray inspection. They are not pin-compatible.
When should I choose EPF10K50VRC240-4 over EPF10K50VRC240-4N?
Choose the EPF10K50VRC240-4 (non-N, SnPb) when assembling for non-RoHS markets such as military, aerospace, and certain industrial programs that still accept lead-bearing solder. Choose the EPF10K50VRC240-4N (lead-free) when the PCB must comply with RoHS directive 2011/65/EU, such as consumer, automotive, and most commercial products sold in the EU. Both are functionally and pin-compatible, so the choice is purely driven by regulatory solder-finish requirements.
Is EPF10K50VRC240-4 suitable for industrial control applications?
Yes, the EPF10K50VRC240-4 is highly suitable for industrial control applications. Its 50K gate density handles typical PLC logic, motor-control state machines, and fieldbus protocol bridges (Profibus, CANopen, Modbus). The 0C to +70C commercial temperature rating covers most factory-floor enclosures. For harsher environments (-40C to +85C), migrate to the EPF10K50VRI240-4N industrial-temperature variant with identical 240-pin RQFP pinout.
What is the best drop-in replacement for EPF10K50VRC240-4?
The best drop-in replacement for EPF10K50VRC240-4 is the EPF10K50VRC240-3N (lead-free, slower speed grade) for fully identical pinout and package, or the EPF10K50VRC240-4N (lead-free variant) for RoHS compliance. Both share the same 240-pin RQFP footprint and FLEX-10K50 logic architecture, enabling direct PCB swap. For new designs with no legacy constraint, the Cyclone IV EP4CE30F23I7N offers modern functionality but requires PCB redesign due to different package and pinout.

Panduan Pemilihan

Choose the EPF10K50VRC240-4 when maintaining a legacy FLEX-10K design that requires bit-exact compatibility with existing firmware, or when targeting long-lifecycle aerospace/military/industrial programs where the original SnPb lead finish is mandated. Its 125 MHz internal Fmax (speed grade -4) is necessary for designs with tight timing closure. For RoHS-compliant assemblies, choose the EPF10K50VRC240-4N instead (lead-free, identical silicon). For timing-relaxed designs that don't need -4 Fmax, the EPF10K50VRC240-3N offers ~20% cost savings. Avoid choosing the -1 or -2 speed grades unless Fmax is irrelevant - they trade 30-40% performance for small cost reductions. For new designs with no legacy constraint, migrate to the Cyclone IV EP4CE30 family for active lifecycle, lower power, and modern I/O support.

Diferensiator Kunci

  • Fastest speed grade in FLEX-10K50VRC240 family (vsEPF10K50VRC240-3N)
  • Original legacy / non-RoHS lead finish (vsEPF10K50VRC240-4N)

Catatan Desain

The EPF10K50VRC240-4 draws substantial ICCINT current during configuration (peak ~500 mA as all SRAM cells initialize) and ~150-300 mA steady-state depending on logic utilization and toggle rate. VCCINT (3.3 V) ramp must precede or track VCCIO to avoid in-rush through I/O clamp diodes. Place a 100 uF bulk capacitor plus 0.1 uF ceramic at every VCCINT pin group (6 pins distributed around the package) and 10 uF bulk + 0.1 uF at each VCCIO bank pin (7 banks). Use a TPS7A4533 or LT1085-3.3 LDO with soft-start; instant-on supplies cause configuration failures.

The 240-pin RQFP package uses 0.5 mm pitch gull-wing leads and requires careful PCB layout. Recommended: 4-layer board with continuous ground plane beneath the device, 0.2 mm (8 mil) trace/space rules, micro-via-in-pad not required. Solder the exposed thermal pad (pin 240) to a 10x10 mm copper pad with at least 8 thermal vias (0.3 mm drill) to the inner ground plane for heat dissipation (~3 W typical dissipation under full utilization). Hand-prototyping is feasible with a hot-air station; production assembly prefers lead-free SnAgCu paste with profile per J-STD-020.

Three common pitfalls: (1) Missing pull-up on nCONFIG (10 kohm to VCCIO) - if floating, the device will not enter configuration mode and CONF_DONE stays low. (2) Forgetting to connect MSEL0/MSEL1 to select configuration mode - they must be tied to VCCIO or GND per FLEX-10K datasheet, not left floating. (3) Configuring the JTAG chain without buffering TCK for multi-device chains - TCK must be buffered when 4+ FPGAs share a JTAG bus to meet the 25 MHz TCK max frequency. Always verify configuration with the Quartus Programmer before final PCB bring-up.

Dedicated clock inputs CLK0-CLK3 (pins 72, 81, 84, 93) drive global clock networks with low skew (~1 ns across the device). Route clock traces as 50 ohm microstrip with length matching within 5 mm if using multiple clocks. Place clock generator (e.g., CY22393) within 25 mm of the FPGA clock pins. Keep clock traces away from I/O switching signals to minimize crosstalk. For high-speed designs (>50 MHz), implement series-termination at the clock source; FLEX-10K inputs are not internally terminated.
