EPF10K50VR1240-4 - 50K FLEX 10K FPGA, 240-Pin BFQFP | Altera
The Altera EPF10K50VR1240-4 is a member of the FLEX 10K Embedded Programmable Logic Device family, delivering approximately 50,000 typical gates in a 240-ball Fine-pitch Ball Grid Array (BFQFP) package with speed grade -4. It is one of the earliest SRAM-based FPGAs to integrate embedded array blocks (EABs), enabling on-chip memory and logic multipliers alongside general-purpose logic elements. An FPGA (Field-Programmable Gate Array) is a programmable logic device that allows engineers to implement custom digital circuits by configuring an array of configurable logic blocks (CLBs), interconnect, and I/O cells. FPGAs belong to the larger hierarchy of programmable logic devices -> logic ICs -> integrated circuits -> semiconductors. The FLEX 10K family was Altera's first to embed array blocks, a predecessor of modern FPGA embedded Block RAM. Key features include roughly 2,880 logic elements (per the DigiKey listing of the related I240 variant), 20,480 typical gates, dedicated embedded array blocks for memory, 5V-tolerant I/O on the V-series, and JTAG-based in-system programmability via the ByteBlaster or BitBlaster cable. The architecture supports asynchronous and synchronous RAM and ROM, multipliers via lookup tables, and cascaded EABs for wide memory functions. The EPF10K50VR1240-4 is fabricated on a 0.42 µm CMOS SRAM process and operates from a 5V core supply with 5V/3.3V multi-voltage I/O. The 240-pin BFQFP package exposes approximately 189 user I/O pins, sufficient for glue logic, bus interfacing, and moderate-density state-machine replacement in legacy industrial designs. Typical applications include industrial control and instrumentation, glue logic replacement, telecommunications backplane interfacing, prototyping of ASIC designs, and embedded control planes where moderate logic density, deterministic timing, and 5V tolerance outweigh the need for modern high-speed transceivers. Designers should treat the -4 speed grade as the slowest in the FLEX 10K V-series; pin-compatible -3, -2, and -1 variants yield faster timing closure. A 0.1 µF decoupling cap per VCC pin plus a bulk cap near the package are essential for SRAM configuration-supply noise margin. This page consolidates distributor pricing, parametric comparisons against speed-grade and package variants, and practical design notes for the FLEX 10K family not found in the standalone datasheet.
EPF10K50VRC240-1 - 50K FLEX 10K FPGA, 240-RQFP, 66MHz | Intel
The Intel EPF10K50VRC240-1 is a member of the FLEX 10K family of SRAM-lookup-table-based Field Programmable Gate Arrays, delivering 50,000 typical gates and 2,880 logic elements in a 240-pin RQFP (PQFP with exposed pad) commercial-grade package. It supports up to 274 user I/O, operates from a 3.3 V core supply with MultiVolt I/O compatibility, and targets embedded programmable-logic applications at internal frequencies around 66 MHz. A Field Programmable Gate Array (FPGA) is a programmable-logic device (PLD) whose architecture combines a dense array of configurable logic blocks (LEs), a programmable routing fabric, and embedded memory. FPGAs occupy the middle ground between fixed-function ASICs and small CPLDs - they offer higher gate counts and richer I/O than CPLDs while remaining reprogrammable, unlike ASICs. The FLEX 10K series was the industry's first family to embed an array of SRAM blocks alongside logic, enabling System-on-a-Programmable-Chip (SOPC) designs where a CPU core, memory, and glue logic coexist on a single device. Key specifications include 2,880 logic elements, 20,480 typical gates, 189 Kbits of embedded SRAM, 240 user I/O, an internal clock frequency up to 66.67 MHz, 0.6 ns propagation delay, and 0.42 µm CMOS process technology. The device also features JTAG boundary-scan test (IEEE 1149.1-1990) support, programmable PCI clamping diodes, slew-rate control, and open-drain output options configured pin-by-pin via the Altera MAX+PLUS II / Quartus design software. The MultiVolt I/O interface separates VCCINT (core supply) from VCCIO (I/O supply), so 5 V-tolerant I/O can be driven from a 3.3 V core - critical when bridging legacy peripherals. The exposed thermal pad on the RQFP-240 package improves heat dissipation for high-utilization designs. Configuration is supported through JTAG, the BitBlaster serial cable, the ByteBlasterMV parallel cable, or the Jam STAPL programming and test language, allowing board-level flexibility. Typical applications include telecommunications glue logic, PCI bridge designs, industrial-control state machines, embedded-protocol bridges, and pre-production ASIC prototyping. The commercial 0-70 °C temperature grade makes it well-suited for indoor enclosures, laboratory instrumentation, and development platforms. When designing with this device, ensure the Quartus MAX+PLUS II toolchain supports the FLEX 10K device family - modern Quartus releases support legacy FLEX devices for compilation. Always confirm supply rails (VCCINT and VCCIO) are decoupled with bulk + ceramic capacitors placed close to the package pins, and respect the exposed-pad soldering guidelines. This page synthesizes distributor pricing, drop-in FLEX 10K alternatives, and practical design notes not found in the manufacturer datasheet, giving engineers a single decision-making reference for legacy Altera FLEX 10K FPGA designs.

The Intel (formerly Altera) EPF10K50VRC240-1N is a FLEX 10K family Field-Programmable Gate Array (FPGA) delivering 50,000 typical gates, 2,880 logic elements, and 189 user I/Os in a 240-pin Power QFP (BFQFP) package with exposed thermal pad. According to manufacturer and distributor listings, the device is built on a 0.42 µm CMOS process, supports an internal core frequency up to 66.67 MHz, and uses a 3.3 V core supply. It belongs to the industry's first embedded programmable logic device (PLD) family, providing System-on-a-Programmable-Chip (SOPC) integration via its embedded array block architecture. What is an FPGA? A Field-Programmable Gate Array is a semiconductor IC composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that engineers can re-program in the field to implement arbitrary digital functions. FPGAs sit above microcontrollers, DSPs, and ASICs in the design flexibility hierarchy: they are slower per gate than ASICs but offer parallel processing, rapid prototyping, and hardware-level reconfigurability that microcontrollers cannot match. The FLEX 10K family pioneered the embedded array block (EAB), which allows on-chip implementation of RAM, ROM, and arithmetic functions alongside the general-purpose logic array. Key features of the EPF10K50VRC240-1N include 20,480 typical logic gates, 360 Logic Array Blocks (LABs), 2,880 logic cells (per DigiKey listing), embedded array blocks (EABs) for memory functions, in-system programmability (ISP) via the serial configuration interface, multi-volt I/O support, and JTAG boundary-scan test per IEEE Std 1149.1. The 'V' in the part number denotes 3.3 V operation, the 'RC240' identifies the 240-pin Power QFP package with exposed pad, the '1' indicates the speed grade, and 'N' indicates a lead-free commercial-temperature version. From an architecture standpoint, the FLEX 10K device integrates continuous interconnect structures (FastTrack) with an array of LABs and EABs, allowing designers to combine wide logic functions with on-chip memory in a single die. The exposed pad on the BFQFP package provides a low-thermal-resistance path for heat dissipation, which is critical at 250 MHz internal operation and 66.67 MHz system performance. Typical applications for the EPF10K50VRC240-1N include communications glue logic, industrial control state machines, PCI bus interfaces, DSP co-processing, prototyping of ASIC designs, and embedded system-on-chip integration. It is also used in legacy telecom infrastructure where the FLEX 10K architecture has long been deployed. When designing with this device, ensure proper decoupling (typically 0.1 µF and 10 µF capacitors near each power pin) and thermal relief through the exposed pad to a sufficient copper pour. Designers should also budget configuration time and choose between serial or parallel configuration modes via the Quartus or MAX+PLUS II design tools.

EPF10K50VRC240-2 - Flex 10K FPGA, 50K Gates, 240-RQFP | Intel
The Intel (formerly Altera) EPF10K50VRC240-2 is a Flex 10K family Field-Programmable Gate Array (FPGA) IC with 50,000 typical gates, 2,880 logic cells, 360 Logic Array Blocks (LABs), and 189 user I/Os, packaged in a 240-pin RQFP (also described as HFQFP/BQFP with exposed pad). The device operates from a 3.3 V core supply and uses a 0.42 µm CMOS process technology with 5-level metal interconnect. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs/LABs) connected through programmable interconnect, allowing hardware designers to implement custom digital logic that can be reconfigured after manufacturing. FPGAs sit at the top of the programmable logic hierarchy: PLD -> CPLD -> FPGA -> System-on-Chip FPGA. The Flex 10K series introduced embedded array blocks (EABs) for System-on-a-Programmable-Chip (SOPC) integration, combining lookup-table based logic with on-chip RAM. Key features of the EPF10K50VRC240-2 include 20,480 typical logic elements, a maximum internal frequency of approximately 125 MHz (66.67 MHz in some datasheet graphs), a propagation delay of 0.6 ns, and embedded array blocks for memory implementation. The -2 speed grade identifies a mid-range performance bin within the Flex 10K family. The device is graded for commercial operating temperature (0 °C to +70 °C) and ships in surface-mount gull-wing RQFP-240. Architecturally, the Flex 10K combines a fine-grained logic fabric (LABs built from 8 logic elements each) with coarse-grained Embedded Array Blocks (EABs), enabling dense on-chip RAM and product-term logic. The 3.3 V core, 0.42 µm process, and SRAM-based configuration make the part volatile (configuration must be loaded at every power-up from a serial or parallel PROM). Typical applications include glue logic and bus interfaces in telecommunications backplanes, industrial control and instrumentation, prototyping of ASIC-equivalent designs, embedded control in test equipment, and legacy system upgrades where the Flex 10K is already qualified. Designers continue to use EPF10K50VRC240-2 in maintenance and low-volume production of mature platforms. When designing with this part, plan for external configuration memory (an EPC1/EPC2 configuration PROM, or a microcontroller) because SRAM configuration cells lose their contents on power-down. Provide proper decoupling on every VCCINT/VCCIO pin and observe I/O banking rules for mixed-voltage interfaces. This page synthesizes distributor pricing, drop-in alternative MPNs from the same Flex 10K family, and practical design notes that go beyond the manufacturer datasheet's tables.
EPF10K50VRC240-2N - 50K-Gate FLEX 10K FPGA, 240-RQFP | Intel
The Intel EPF10K50VRC240-2N is a member of the FLEX 10K family of field-programmable gate arrays (FPGAs), delivering 50,000 typical gates, 2,880 logic elements/cells, and 360 logic array blocks (LABs) in a 240-pin RQFP (BFQFP with exposed pad) package. Operating from a 3.3 V supply with a 0.42 µm CMOS process and a maximum internal frequency of 125 MHz, this device targets commercial-temperature digital logic designs that need mid-range density, embedded array blocks (EABs) for RAM/ROM, and 189 user I/Os. The "V" suffix denotes the 3.3 V core supply variant, "RC" indicates the RQFP package, "240" is the pin count, "-2" is the speed grade, and the trailing "N" marks lead-free / Pb-free assembly. An FPGA (Field-Programmable Gate Array) is a programmable logic device that lets engineers implement arbitrary digital logic - combinational gates, flip-flops, state machines, and memory blocks - by downloading a configuration bitstream after the IC is soldered onto the board. The FLEX 10K series was Intel/Altera's first generation to embed array blocks (EABs) for on-chip dual-port RAM, marking the industry's first System-on-a-Programmable-Chip (SOPC) integration. FPGAs sit hierarchically under programmable logic devices (PLDs), complex programmable logic devices (CPLDs), and finally the broader semiconductor / integrated circuit taxonomy. Key features include 50,000 system gates, 20,480 flip-flop-based register bits, 2,880 logic elements, a maximum propagation delay of approximately 0.6 ns (66.67 MHz internal timing reference), 189 programmable I/O pins, four embedded array blocks (EABs) for distributed SRAM, JTAG-based IEEE 1149.1 boundary-scan testing, in-system programmability (ISP) via the serial passive configuration scheme, multi-volt I/O support (3.3 V core, 5.0 V-tolerant I/O), and a commercial 0 °C to 70 °C operating range. The exposed pad on the 240-RQFP package improves thermal dissipation during continuous logic switching. The FLEX 10K architecture uses a row/column-based logic array, with each LAB containing eight logic elements (LEs), each LE built around a 4-input look-up table (LUT) plus a programmable flip-flop. EABs provide up to 2 Kbits of dual-port RAM each, allowing on-chip FIFOs, lookup tables, and small scratch-pad memories without external SRAM. Configuration is loaded from a serial EPROM or via the ByteBlaster / JTAG download cable in development flows, and the bitstream is held in SRAM cells so the device is re-programmable in the field an unlimited number of times. Typical applications include custom glue logic in industrial control boards, PCI bridge and bus-interface controllers, telecommunications channel cards, prototyping of ASIC designs before mask production, DSP pre/post-processing pipelines, image processing front-ends, and embedded control subsystems. With 50K gates of usable logic, the EPF10K50VRC240-2N is well-suited to designs that need more capacity than a 10K30 device but do not yet justify the silicon cost of a 10K100 or 10K130. When designing with the EPF10K50VRC240-2N, use the Quartus II (legacy) or MAX+PLUS II toolchain for synthesis, fitting, simulation, and programming file generation. Ensure clean 3.3 V core and I/O rail decoupling, observe the configuration mode wiring (MSEL pins), and respect JTAG chain order if multiple devices share the same boundary-scan bus. Because this device is in the legacy FLEX 10K family, plan for end-of-life (EOL) sourcing via franchised distributors or authorised aftermarket inventory. This page synthesises franchised distributor pricing, same-package FLEX 10K drop-in alternatives, and practical design notes not consolidated in the legacy Altera datasheet.

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.
EPF10K50VRC240-3N - 50K-Gate FLEX 10K FPGA, 189 I/O, 240-RQFP | Intel
The Intel (formerly Altera) EPF10K50VRC240-3N is a member of the FLEX 10K family of Field Programmable Gate Arrays (FPGAs) housed in a 240-pin RQFP (Power Quad Flat Pack) package with exposed thermal pad. Built on a 0.42 µm CMOS SRAM-based process, this device integrates 50,000 typical gates, 2,880 logic cells (logic elements), 20,480 bits of embedded array memory (EAB), and 360 Logic Array Blocks (LABs), providing 189 usable I/O pins across the package. According to manufacturer datasheet data, the part operates from a 3.3 V core supply, supports internal frequencies up to 125 MHz, and is qualified for the commercial 0 °C to +70 °C temperature range. What is a FLEX 10K FPGA? The FLEX 10K family was one of the industry's first embedded programmable logic device families, providing System-on-a-Programmable-Chip (SOPC) integration. It combines a fine-grained Logic Element (LE) fabric with coarse-grained Embedded Array Blocks (EABs) that can be configured as RAM, ROM, or multiplier blocks. As an SRAM-based PLD, the FLEX 10K sits within the broader hierarchy: programmable logic device -> PLD -> FPGA -> SRAM-based FPGA -> embedded-array FPGA -> FLEX 10K family. The 'V' suffix in the package code denotes the 240-RQFP option, and the speed grade '-3' places it in the mid-tier of FLEX 10K performance bins. Key differentiating features of the EPF10K50VRC240-3N include its 189 available user I/Os, the high-density 360-LAB fabric that allows efficient state-machine and datapath partitioning, 0.42 µm CMOS process for low static power, and propagation delay figures consistent with a -3 speed grade at 0.6 ns internal. Each EAB provides 2,048 bits of memory that can be cascaded to form FIFOs, ROM look-up tables, or DSP multiplier blocks. The device is in-system programmable through the Altera/Quartus ByteBlaster or compatible JTAG-style configuration paths. Architecturally, the FLEX 10K combines a sea-of-LEs routing fabric with embedded array blocks arranged in columns. Configuration is stored in SRAM cells, meaning the device must be reconfigured on every power-up - the configuration bitstream is typically loaded from a serial PROM. The 'RC240' package suffix identifies the 240-pin Power QFP with exposed thermal pad for improved heat dissipation at high toggle rates. Typical applications include industrial glue logic replacement, communications protocol bridging, and legacy ASIC prototyping. Engineers select this part when migrating older Altera designs to a known-stable platform, or when the specific I/O count and LAB density match an existing PCB layout. The 240-RQFP package is also well-suited to designs where fine-pitch BGA rework tools are not available, since QFP leads are easier to inspect and rework with conventional soldering equipment. When designing with this part, observe the 3.3 V I/O and core supply requirements and use the Quartus II design software (or compatible legacy tools) for synthesis, place-and-route, and timing closure. Confirm whether active inventory is needed or whether the legacy part can be replaced with a newer Cyclone device - the FLEX 10K family has been superseded by Intel's Cyclone and MAX families for new designs.
EPF10K50VRC240-4 - 50K Gate FLEX-10K FPGA, 240-Pin RQFP | Altera / Intel
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. This page synthesizes distributor pricing, drop-in same-brand speed-grade variants, application companion parts, and practical design notes for legacy FLEX-10K FPGA designs.
EPF10K50VRC240-4N - 50K-Gate FLEX-10K FPGA, 240-RQFP | Intel / Altera
The Intel / Altera EPF10K50VRC240-4N is a member of the FLEX-10K family of embedded programmable logic devices (PLDs) that pioneered System-on-a-Programmable-Chip (SOPC) integration. The device integrates 50,000 typical gates and 2,880 logic cells with 36 embedded array blocks (EABs) and 360 logic array blocks (LABs), delivering approximately 189 user I/Os from a 240-pin RQFP (exposed-pad BFQFP) package. It is a CMOS device with a typical internal frequency of 66.67 MHz and a worst-case propagation delay near 0.6 ns, with a supply of 3.3 V core on the -4 speed grade. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that combines an array of configurable logic blocks, programmable interconnect, and configurable I/O cells on a single semiconductor die. FPGAs sit hierarchically under the broader category of programmable logic devices, alongside CPLDs, and serve as the dominant platform for digital logic prototyping, glue logic, DSP acceleration, and high-volume ASIC replacement when mask costs are prohibitive. The FLEX-10K family was the industry's first PLD family with embedded array blocks, allowing on-chip implementation of RAM, ROM, FIFOs, and multipliers directly in the logic fabric. Key features include 50,000 usable gates, 2,880 logic elements, 36 EABs providing a total of 20,480 bits of embedded memory, 189 maximum user I/Os, and a 3.3 V core supply with 5 V tolerant I/O options on selected members. The device is offered in a commercial 0 to 70 C operating range and is qualified to the -4 speed grade. The 240-pin RQFP exposed-pad package enables surface-mount assembly and improved thermal dissipation relative to non-exposed-pad RQFP variants. Typical applications include telecommunications glue logic, industrial control, prototyping for ASIC designs, low-volume digital signal processing pipelines, and bus-interface bridging. The high gate count and embedded memory make the EPF10K50 suitable for designs that need substantial on-chip storage and parallel datapaths but that do not require the very latest in process technology. When designing with this part, ensure that the Quartus II or MAX+PLUS II toolchain is used, since the FLEX-10K family predates modern Quartus Prime support. Plan PCB layout around the exposed pad for thermal management, and verify JTAG programming interface compatibility with the chosen configuration PROM.
EPF10K50VRI240-3 - FLEX 10K 50K Gates FPGA | Intel | Altera
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.

EPF10K50VRI240-3N - 50K Gates FLEX-10K FPGA | Altera | Industrial
The Altera EPF10K50VRI240-3N is a member of the FLEX-10K family of Field Programmable Gate Arrays (FPGAs) delivering 50,000 typical gates, 2,880 logic cells (Logic Elements), and 20,480 bits of embedded array RAM in a 240-pin RQFP (RQFP-240 / BQFP-240 with exposed pad) industrial-temperature package. The device is fabricated on a 0.42 µm CMOS process, supports 189 user I/O pins, and operates from a 3.3 V core supply with the -3 speed grade delivering up to 125 MHz internal performance. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the high density of gate arrays with the in-system reconfigurability of logic. The FLEX-10K family specifically pioneered the industry's first embedded programmable logic devices, providing System-on-a-Programmable-Chip (SOPC) integration by combining an Embedded Array Block (EAB) for megafunctions such as efficient memory and specialized logic, with a Logic Array Block (LAB) fabric for general-purpose logic. This architecture positions the FLEX-10K within the broader hierarchy: FPGA -> programmable logic device -> programmable logic IC -> semiconductor. Key features of the EPF10K50VRI240-3N include 360 LABs, 12 EABs of 2,048 bits each, four Phase-Locked Loops (PLLs) for clock management, in-system programmability through the IEEE 1149.1 JTAG interface, multi-volt I/O support (2.5 V / 3.3 V / 5.0 V tolerant), and 4 mA typical quiescent current in standby. The 'I' in the part suffix indicates the industrial temperature range (-40 °C to +85 °C), and the 'N' suffix indicates a lead-free / Pb-free assembly suitable for RoHS-compliant designs. Technically, the FLEX-10K architecture implements SRAM configuration memory, requiring a configuration device (EPC) or microcontroller for power-up bitstream loading. The Look-Up Table (LUT)-based LE provides fast 4-input combinational logic and a dedicated register, while the EABs implement dual-port RAM, ROM, FIFO, or multiplier megafunctions. The 240-pin RQFP package offers a 32.0 mm x 32.0 mm body with a 0.5 mm pitch, making it compatible with conventional SMT assembly lines and rework tooling. Typical applications for the EPF10K50VRI240-3N include industrial control and factory automation PLCs, telecommunications interface cards, prototype ASIC emulation, glue-logic consolidation on legacy 5 V backplanes, digital signal processing front-ends, and bus-interface bridging (PCI, ISA, VME). The -3 speed grade and 189 user I/Os make it well suited to designs that require moderate logic density and high pin count rather than the highest possible clock frequency. When designing with this part, note that it is a mature, legacy FPGA family and is no longer recommended for new designs. Modern replacements such as the Altera / Intel Cyclone IV or MAX 10 series offer lower cost, lower power, smaller packages, and active support. For new designs targeting the same density class, evaluate Cyclone IV EP4CE40 or EP4CE55 in EQFP or BGA packages as a forward-compatible migration path.

FPGAs belong to the broader hierarchy: programmable logic device (PLD) -> complex programmable logic device (CPLD)/FPGA -> digital semiconductor -> integrated circuit. The FLEX-10K family was Altera's first "System-on-a-Programmable-Chip" (SOPC) platform, embedding array blocks (EABs) that allow megafunctions such as RAM, ROM, and multipliers to be physically realised on-die alongside general-purpose logic. Key features include 468 Logic Array Blocks (LABs), embedded array blocks for on-chip memory, JTAG (IEEE 1149.1) boundary-scan support, in-system programmability via SRAM configuration, and a dedicated configuration EPROM interface.

With 189 available user I/Os, the part delivers substantial off-chip connectivity for bus-intensive glue-logic, bridge, and control applications. The 240-pin BFQFP exposed-pad package aids thermal dissipation, while the 0.42 µm process gives the -4 speed grade typical propagation delays near 0.4 ns per LE. The architecture uses SRAM configuration cells, meaning the FPGA must be configured at each power-up from an external serial or parallel PROM (such as the EPC2 or EPC8 configuration devices). Typical applications include industrial glue-logic and bus-bridging, telecom control-plane ASIC prototyping, military/aerospace legacy systems, and PCI bridge/controller emulation. The large gate count and abundant I/O make the EPF10K70RC240-4N a frequent choice for migrating older gate-array designs onto a programmable platform. Design consideration: as the configuration is SRAM-based, a power-on reset and reliable configuration source are mandatory. Designers should use the dedicated CONF_DONE and nSTATUS pins to monitor configuration status and provide a clean POR sequence.

EPF6010ANTC100-1 - 880 Logic Elements FLEX 6000 FPGA | Intel
The Intel EPF6010ANTC100-1 is a member of the FLEX 6000 family of SRAM-based FPGAs, delivering 880 logic elements organized as 88 LABs/CLBs and approximately 10,000 usable gates. Housed in a 100-pin TQFP package, this device provides 71 user I/O pins and operates from a single 3.0V to 3.6V supply. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the architectural flexibility of gate arrays with the design-turnaround advantages of in-system programmability. Within the broader semiconductor hierarchy, an FPGA sits between Application Specific Integrated Circuits (ASICs) and general-purpose processors, offering hardware-level parallelism that microcontrollers and DSPs cannot match. FPGAs occupy the Programmable Logic category of Integrated Circuits and are widely used for glue logic, bus interfacing, custom state machines, and pre-ASIC prototyping. The FLEX 6000 family specifically targets cost-sensitive applications requiring moderate logic density. Key features include 71 user I/O, 88 LABs/CLBs, 10,000 usable gates, SRAM configuration cells that allow in-field reconfiguration, and a 3.3V core supply with 5V-tolerant I/O support on selected pins. The device supports JTAG (IEEE 1149.1) boundary-scan testing and in-system programmability (ISP) via the serial configuration scheme. Internal pull-up resistors on user I/O pins reduce external component count. Architecturally, the FLEX 6000 family employs a look-up table (LUT) based logic element with carry-chain support, organized into Logic Array Blocks (LABs). Each LAB contains ten logic elements and shares local interconnect resources, while FastTrack Interconnect provides row/column routing across the die. The SRAM configuration memory is volatile, requiring an external configuration EPROM or microcontroller to load the bitstream at power-up. Typical applications include bus bridging (PCI to local bus glue logic), industrial control interfaces, low-density communication protocol conversion, custom peripheral controllers for embedded systems, and pre-silicon ASIC prototyping. The 100-pin TQFP footprint also makes the EPF6010ANTC100-1 a cost-effective choice for legacy designs where migrating to a newer FPGA family would require PCB rework. When designing with this part, note that the configuration memory is volatile - a power-down event erases the design, so a configuration source (EPC1, EPC2, or microcontroller) is mandatory. The 3.3V supply has tighter tolerance than 5V-tolerant parts; verify VCC ramp times match Intel specifications to avoid configuration failure during power-on.

It features a -2 speed grade and commercial operating temperature range, delivering a balance of logic density and I/O flexibility for glue-logic, interface bridging, and custom digital state-machine designs. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit that engineers can configure after manufacturing to implement arbitrary digital logic functions. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs) -> programmable logic -> digital logic ICs -> semiconductors, occupying the high-density end of this hierarchy. FPGAs complement ASICs by offering lower NRE cost and faster time-to-market, and complement microcontrollers by providing parallel hardware execution at deterministic nanosecond-scale latency. The FLEX 6000 family uses a look-up-table (LUT)-based logic element architecture with continuous interconnect, optimized for cost-sensitive applications requiring modest logic capacity. Key features of the EPF6010ANTC100-2 include 880 logic elements, 71 user I/O pins, 5V core tolerance (FLEX 6000A variants), in-system programmability via the IEEE 1149.1 (JTAG) boundary-scan interface, and a 100-pin TQFP surface-mount package measuring 14x14 mm with 0.5 mm pitch. The device supports asynchronous, synchronous, and level-sensitive memory architectures and integrates dedicated carry chains for arithmetic functions and cascade chains for wide fan-in logic. The EPF6010ANTC100-2 employs a SRAM-based configuration cell that allows unlimited reconfiguration, supported by the Altera MAX+PLUS II and Quartus design tools. The on-chip logic array is organized into Logic Array Blocks (LABs), each containing ten logic elements with local interconnect. Global routing resources include row and column channels that distribute clocks, clears, and high-fan-out signals across the device. Typical applications include peripheral bus interfacing (PCI, ISA, VME bridge logic), industrial control glue logic, telecommunication line-card glue functions, ASIC prototyping and emulation, and custom DSP pre/post-processing front-ends. With 71 I/O available, the part accommodates wide parallel buses and multi-protocol bridging scenarios. When designing with the EPF6010ANTC100-2, ensure that the configuration memory is loaded from a valid source (EPROM, microcontroller, or JTAG) at every power-up. Note that the FLEX 6000 family has reached end-of-life status from Intel PSG; consult PCN documents before new designs and verify long-term availability for production runs. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone - giving engineers a faster path to sourcing and second-source selection for legacy FLEX 6000 designs.
EPF6010ANTC100-3 - FLEX 6000 FPGA 880 LE 71 I/O 100-TQFP | Intel
The Intel (Altera) EPF6010ANTC100-3 is a member of the FLEX 6000 family of SRAM-based Field-Programmable Gate Arrays (FPGAs) housed in a 100-pin Thin Quad Flat Pack (TQFP) package. The device integrates 880 Logic Elements (LEs), 71 user I/O pins, and an embedded array of 16,000 RAM bits, providing flexible reconfigurable logic for glue-logic, bus-interface, and state-machine applications. Built on a 0.42 µm CMOS SRAM process with a 5 V core voltage, it is rated speed grade -3 and supports in-system programmability via the IEEE 1149.1 (JTAG) interface. An FPGA (Field-Programmable Gate Array) is a reconfigurable integrated circuit in the broader hierarchy of programmable logic devices (PLD) -> logic ICs -> semiconductors. FPGAs differ from ASICs by offering post-fabrication logic changes, and from CPLDs by providing finer-grained distributed flip-flops, embedded RAM blocks, and richer I/O standards. The FLEX 6000 family is positioned as a low-cost, low-density alternative to the APEX and FLEX 10K families, targeting glue logic, address decoding, FIFO buffers, and bus-bridge functions. Key features of the EPF6010ANTC100-3 include 880 Logic Elements (each containing a 4-bit LUT and a flip-flop), a maximum operating frequency of up to 105 MHz for 16-bit counters, 16 Kbit embedded SRAM organized as 8 LABs, support for LVTTL, LVCMOS, PCI, and other I/O standards through programmable I/O elements (IOEs), and MultiVolt I/O allowing 3.3 V or 5 V interface to surrounding logic. The device is configured via JTAG or an EPC configuration EPROM, supporting 8-bit parallel or serial configuration modes. Typical applications include legacy industrial controllers, telecommunications glue logic, PCI bus interfaces, peripheral controllers, and low-density DSP pre/post-processing. The wide 5 V tolerance of the I/O pins makes the EPF6010ANTC100-3 a practical choice for retrofitting 5 V legacy systems where modern 3.3 V FPGAs would require level shifters. When designing with this part, note that the FLEX 6000 family is mature and approaching end-of-life. Engineers designing new platforms should evaluate MAX II, MAX V (CPLDs), or Cyclone series (low-cost FPGAs) as modern alternatives. For legacy sustainment, designers must preserve the JTAG chain, ensure the EPC configuration EPROM is correctly selected, and provide a clean 5 V supply with proper decoupling.
EPF6010ATC100-1 - FLEX 6000 FPGA 880 Cells 100-TQFP | Altera
The Altera (Intel) EPF6010ATC100-1 is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays, delivering approximately 10,000 typical gates, 880 logic elements, and 71 user I/O in a 100-pin Thin Quad Flat Pack (TQFP) package. Built on a 0.42 µm CMOS process, the device supports a maximum toggle rate of 200 MHz and operates from a 3.3 V core supply, making it suitable for glue-logic, bus-interface, and state-machine consolidation in cost-sensitive industrial designs. A Field Programmable Gate Array (FPGA) is a programmable logic device that combines the integration density of an application-specific integrated circuit (ASIC) with the flexibility of in-system reconfiguration. FPGAs sit within the digital semiconductor hierarchy as programmable ASIC alternatives: FPGA → programmable logic device (PLD) → logic IC → integrated circuit → semiconductor. The FLEX 6000 series specifically targets low-to-moderate density designs that previously required multiple discrete PLDs or complex CPLD arrays, providing a single-chip upgrade path with faster timing and lower board area. Key features of the EPF6010ATC100-1 include 88 Logic Array Blocks (LABs), 16 Logic Elements per LAB, 71 maximum user I/O, 5 V tolerant I/O with 3.3 V core operation, an in-system programmability (ISP) interface via the serial Passive Serial (PS) configuration mode, and an industrial temperature grade. The 100-pin TQFP package provides a 1.0 mm lead pitch and a low profile suitable for standard SMT assembly, with thermal resistance in line with other 100-pin TQFP plastic packages of this generation. Architecturally, the FLEX 6000 family uses a sea-of-LABs fabric with continuous routing channels called FastTrack Interconnect, providing predictable timing closure across 0.42 µm process geometry. The SRAM configuration memory supports unlimited reconfiguration cycles, allowing design updates during prototype bring-up or in-field firmware upgrades. A built-in JTAG (IEEE 1149.1) interface enables boundary-scan test and programming verification on production lines. Typical applications for the EPF6010ATC100-1 include industrial control glue logic, communication bridge and protocol conversion cards, legacy peripheral interfacing, custom state machines for motor control, test and measurement front-end signal routing, and education/hobby platforms where the device remains supported by the legacy Altera MAX+PLUS II and Quartus design tools. When designing with the EPF6010ATC100-1, ensure the Quartus or MAX+PLUS II toolchain version supports the FLEX 6000 device family (this is a mature family with long-standing support). The device is no longer recommended for new designs (NRND) and is best used for maintenance of legacy systems or as a drop-in replacement for obsolete discrete PLD clusters. Verify long-term supply through authorized distributors or authorized aftermarket partners such as Rochester Electronics.
