EPF10K30ETI144-2 - 30K-Gate FLEX 10KE FPGA, 102 I/O, 144-TQFP | Intel
The Intel (formerly Altera) EPF10K30ETI144-2 is a member of the FLEX 10KE embedded programmable logic family, integrating approximately 30,000 typical gates, 1,728 logic elements, and 24,576 bits of embedded array memory (EABs) in a 144-pin TQFP package. As a 2.5 V core SRAM-based FPGA with 102 user I/Os and a -2 speed grade, it targets glue-logic, bus-interface, and embedded control designs that benefit from on-chip dual-port RAM blocks for FIFO and register-file functions. What is an FPGA? A Field Programmable Gate Array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs/LABs), programmable routing, and I/O cells that the designer can wire up after manufacture to implement arbitrary digital circuits. FPGAs sit in the broader hierarchy: programmable logic device (PLD) -> FPGA -> SRAM-based FPGA -> embedded-block FPGA. The FLEX 10KE family added Embedded Array Blocks (EABs) so each block can act as dual-port RAM, ROM, or a multiplier-style lookup - the 'embedded' name comes from this on-chip memory integration rather than a hard processor core. Key features include 216 Logic Array Blocks (LABs), 102 maximum user I/O pins, an internal operating frequency up to 200 MHz, and CMOS logic family operation. The 144-pin TQFP (Thin Quad Flat Pack) surface-mount package exposes JTAG-compliant configuration and supply rails at 2.375 V to 2.625 V, and supports in-system programmability via the Altera (now Intel) Quartus / MAX+PLUS II toolchain. The EPF10K30E architecture combines a fine-grained logic fabric with coarse-grained EABs, giving designers block-RAM density similar to early SoC integration without leaving the PLD paradigm. Pin-compatible speed/grade variants (e.g., -3, -2, -1) allow timing tuning without PCB rework, while different packages (TQFP-144, QFP-208, BGA-256, BGA-484) of the same die give I/O-count flexibility across board revisions. Typical applications include industrial control glue logic, telecom line-card bus bridges, legacy peripheral emulation, prototyping of ASIC logic, and embedded DSP datapaths where the EABs can implement small multiply-accumulate tables. The industrial temperature grade (-40C to +85C inferred from the 'I' suffix) suits factory-floor and outdoor enclosures. When designing, plan for I/O bank voltage compatibility, leave the JTAG chain accessible for factory programming, and pair the EPF10K30E with a configuration PROM (EPCS or EPC2) for standalone boot. Note that the FLEX 10KE family is mature/legacy - check Intel's product longevity program for current supply status before new designs.

EPF10K30ETI144-2N - FLEX 10KE FPGA 30K Gates 144-TQFP | Intel
The Intel (formerly Altera) EPF10K30ETI144-2N is a member of the FLEX 10KE family of Embedded Programmable Logic Devices (PLDs), delivering 30,000 typical gates, 1,728 logic elements, and 24,576 bits of embedded SRAM in a 144-pin TQFP package. The device is fabricated on a 0.22 µm CMOS process, operates from a 2.5 V core supply (VCCINT) with MultiVolt I/O support, and is rated for industrial temperature operation (-40 °C to +85 °C). The "-2" speed grade and "N" lead-free suffix denote a moderate-performance, Pb-free industrial-temperature member of the FLEX 10KE family. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit that can be configured by the customer after manufacture to implement arbitrary digital logic. Architecturally, an FPGA sits between fixed-function ASICs and general-purpose processors in the design hierarchy: ASIC > FPGA > CPLD > PLD > programmable logic. FPGAs like the FLEX 10KE family extend traditional gate-array logic with on-chip embedded memory blocks, enabling System-on-a-Programmable-Chip (SOPC) integration of megafunctions such as microcontrollers, FIFOs, DSP filters, and custom peripherals. Key features of the EPF10K30ETI144-2N include 102 user I/O pins, 216 Logic Array Blocks (LABs) in the structured Logic Element array, a MultiVolt I/O interface supporting 2.5 V/3.3 V/5.0 V mixed-voltage operation, PCI-compliant I/O buffers with selectable pull-up clamping diodes, slew-rate control, and open-drain output options configured on a pin-by-pin basis via Altera logic options. The embedded array blocks (EABs) provide synchronous dual-port RAM, ROM, and multiplier implementations without external memory. The FLEX 10KE architecture combines a fine-grained Logic Element fabric with coarse-grained Embedded Array Blocks, a flexible interconnect (FastTrack), and a continuous I/O ring supporting a variety of single-ended and differential I/O standards. This hybrid fabric allows designers to implement glue logic, state machines, and memory-intensive megafunctions on a single chip while preserving deterministic timing for the FPGA fabric. The 0.22 µm process provides mature, low-power operation with extensive third-party tool support from the legacy Altera MAX+PLUS II and Quartus flows. Typical applications include industrial control and factory automation, telecommunications line-card glue logic, PCI interface bridging, prototype ASIC replacement, and low-volume embedded systems requiring on-chip memory and flexible I/O voltage. The 144-TQFP footprint supports a hand-solderable, low-cost PCB assembly process that is well suited to industrial and legacy designs. When designing with this device, ensure the Quartus or MAX+PLUS II toolchain version is matched to the FLEX 10KE device support, because newer Quartus releases have removed legacy FLEX device support. For new designs, consider migrating to the MAX II or Cyclone families, since FLEX 10KE is a mature, last-time-buy product line.

The Intel (formerly Altera) EPF10K30ETI144-3 is a high-density FLEX-10KE family Field Programmable Gate Array (FPGA) IC integrating 1728 logic elements, 216 logic array blocks (LABs), and 24,576 bits of embedded RAM in a 144-pin LQFP (Low-profile Quad Flat Pack) package. It provides 102 programmable user I/O pins, supports an equivalent gate count of 119,000, and runs at a 12.5 ns pin-to-pin logic delay graded for industrial temperature operation (-40C to +85C). The device is built on a 2.5 V/3.3 V core architecture with 5 V-tolerant I/O, giving it wide applicability in mixed-voltage legacy designs. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) containing an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and I/O cells that the user can re-program after manufacture to implement arbitrary digital logic. In the broader semiconductor taxonomy, an FPGA sits below ASICs and ASSPs in volume efficiency but above discrete glue logic in integration density, making it the optimal choice for prototyping, low-volume production, and time-to-market-critical designs. The FLEX-10KE family in particular pioneered embedded array block (EAB) memory, blending distributed logic and dedicated RAM in the same fabric. Key features of the EPF10K30ETI144-3 include 102 user I/Os routed to four I/O banks, JTAG-based in-system programmability via the IEEE 1149.1 boundary-scan interface, multi-volt I/O support for interfacing to 5.0 V, 3.3 V and 2.5 V buses, and SRAM-based configuration memory allowing unlimited reconfigurations in the field. The 12.5 ns speed grade (the '-3' suffix) is the mid-tier option in the FLEX-10KE family, trading absolute speed for cost savings versus the -4 grade. Architecturally, the device pairs 1728 logic elements across 216 LABs with embedded array blocks (EABs) providing true dual-port and single-port RAM of up to 24,576 bits. Each LAB contains 8 logic elements and local interconnect, while FastTrack Interconnect provides predictable delay across rows and columns. The 144-pin LQFP (1.6 mm height) is the most popular low-density FLEX-10KE package, balancing pin access with hand-solder-friendly lead pitch. Typical applications include industrial control logic, telecom glue logic, networking bridges and protocol converters, PCI bridge and bus interface glue, DSP co-processing front-ends, and legacy 5 V system retrofits. The wide I/O count makes the part equally suitable for prototyping ASIC designs before mask commitment. When designing with this device, route all four I/O bank reference voltages (VCCIO pins) and observe the 2.5 V/3.3 V core supply sequencing requirements. JTAG configuration is recommended for production because it allows fast in-system updates and supports read-back verification.

EPF10K30RC20-4 - FLEX 10K 30K Gate FPGA, 5V, PQFP-240 | Altera
The Altera EPF10K30RC20-4 is a member of the FLEX 10K family of Embedded Programmable Logic Devices (EPLDs) based on reconfigurable CMOS SRAM elements and the Flexible Logic Element MatriX (FLEX) architecture. The -4 speed grade device integrates up to approximately 30,000 equivalent gates with 1,728 logic elements and 6 embedded array blocks (EABs), providing 24,576 bits of on-chip RAM, in a 240-pin Power Quad Flat Pack (RC/PQFP-240) surface-mount package. It is one of the industry's first embedded PLDs, capable of implementing common gate-array megafunctions and integrating entire subsystems on a single die. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device that allows designers to configure digital logic after manufacturing using a hardware description language or schematic entry. The FLEX 10K architecture combines a logic array with embedded array blocks, which are dual-port RAM blocks optimized for high-speed memory and DSP functions. Within the broader hierarchy, FPGAs sit above CPLDs in density and below mask-programmed ASICs in non-recurring engineering cost; FLEX 10K devices pioneered embedded memory and are positioned between pure logic FPGAs and modern SoC FPGAs that integrate hard processor cores. Key features include a typical gate count of approximately 30,000 (up to 50,000 maximum), 12,000 usable gates, 5.0 V core supply with 5.0 V TTL-compatible I/O, in-system programmability via the IEEE 1149.1 JTAG interface, multi-volt I/O support, and four FastTrack interconnect routing channels. The -4 speed grade corresponds to a -4 speed bin providing pin-to-pin logic delays around 5 ns in the family, and the device supports configuration via serial configuration EPROMs, JTAG, or passive serial/parallel modes. Architecturally, each logic element contains a 4-input look-up table, a programmable flip-flop, and dedicated carry and cascade logic for fast arithmetic and wide fan-in functions. The six EABs each provide 4 Kbits of RAM that can be cascaded for wider or deeper memory, effectively implementing on-chip dual-port RAM, ROM, FIFO, and multiplier functions without consuming logic resources. The FastTrack continuous routing network with horizontal and vertical channels provides fast, predictable interconnect across the entire device. Typical applications of the EPF10K30RC20-4 include telecommunications glue logic, bus-bridging interfaces, peripheral controllers, high-speed datapath glue logic in test equipment, prototype ASIC emulation, and embedded control in industrial automation. The 240-pin PQFP package with 0.5 mm pitch was the workhorse high-density FPGA footprint of the 1990s, well-suited for moderate-speed (typically 60-80 MHz internal) glue logic. When designing with this device, note that it is a 5.0 V part and predates the multi-volt tolerant I/O standards of later FPGAs; level translation to 3.3 V peripherals is required for modern mixed-voltage designs. Configuration EPROM (EPC1/EPC2/EPC1441) selection must match the chosen configuration mode, and the JTAG chain must be terminated correctly for in-system programming. This part is no longer recommended for new designs - the FLEX 10K family has been superseded by MAX 7000/AE, MAX II, Cyclone, and later device families with lower power and higher density.

The Intel / Altera EPF10K30RC208-4N is a member of the FLEX 10K family of Field-Programmable Gate Arrays (FPGAs), delivering approximately 30,000 typical ASIC-equivalent gates, 1,728 logic elements (cells), 12,288 bits of embedded memory, and 147 user I/O pins housed in a 208-pin RQFP (Power Quad Flat Pack) package with exposed thermal pad. According to the manufacturer datasheet, the device is built on a 0.42 µm CMOS process and is offered in a -4 speed grade optimized for higher system clock performance in 5 V systems. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines a matrix of configurable logic blocks (LABs), embedded memory arrays, and programmable I/O elements on a single die, allowing hardware designers to implement custom digital logic, glue logic, bus bridges, and state machines without fabricating a custom ASIC. FPGAs occupy the same design role as CPLDs, ASICs, and microcontrollers in the wider hierarchy of digital semiconductors, but are distinguished by their very high logic density, embedded SRAM blocks (in the case of FLEX 10K), and parallel-routing architecture. The FLEX 10K family was the industry's first to integrate embedded array blocks, enabling System-on-a-Programmable-Chip (SOPC) implementations that pair megafunctions with conventional programmable logic. Key features of the EPF10K30RC208-4N include 216 Logic Array Blocks (LABs) that combine into 1,728 logic cells, four Embedded Array Blocks (EABs) implementing 12,288 RAM bits (configurable as RAM or ROM), 147 programmable user I/O pins, in-system programmability via SRAM configuration cells, multi-volt I/O support (3.3 V and 5 V), and a JTAG-compliant boundary-scan test interface. The 208-pin RQFP package supports surface mounting and provides thermal performance suitable for industrial-grade designs with adequate airflow or heatsinking. Architecturally, the FLEX 10K family pairs a continuous row of EABs with rows of LABs, allowing wide memory functions (FIFOs, RAM, ROM, dual-port RAM) to be embedded alongside general-purpose logic. The -4 speed grade indicates a faster internal interconnect delay and higher usable clock rate compared with -3, -2, and -1 grades of the same die. The part is specified over the commercial 0 °C to 70 °C operating range and is fully compatible with the Altera MAX+PLUS II and Quartus design tools for schematic, VHDL, and Verilog entry. Typical applications include telecommunications line cards, industrial control and factory automation, glue logic and bus interfacing in legacy systems, prototyping prior to ASIC conversion, and test equipment that demands flexible I/O and embedded memory. The 147 I/O count and embedded memory make the device well suited for designs that bridge between microprocessors, peripherals, and custom peripherals without resorting to multiple CPLDs. When designing with the EPF10K30RC208-4N, engineers should validate the 5 V VCCIO configuration against downstream devices, ensure the JTAG chain follows the IEEE 1149.1 standard, and observe the configuration-mode selection pins at power-up. Because this part is a member of the legacy FLEX 10K family, it is widely used in long-lifecycle industrial and telecom systems and is supported through mature design tools and verified reference designs.

The Altera EPF10K30RC240-3 is a member of the FLEX 10K family of SRAM-based CMOS Field Programmable Gate Arrays, integrating approximately 30,000 typical gates and 1,728 logic elements (LEs) inside 216 Logic Array Blocks (LABs). Housed in a 240-pin RQFP / BFQFP exposed-pad package, it provides 189 user I/O pins, supports a maximum internal operating frequency around 125 MHz, and operates from a 5 V supply. The "-3" suffix denotes the speed grade, with this part rated at -0.6 ns propagation delay / roughly 125 MHz Fmax according to the FLEX 10K family datasheet. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose logic function is defined after manufacturing by the end user. FPGAs sit hierarchically within programmable logic devices (PLDs) alongside CPLDs, and they themselves contain an array of configurable logic blocks (CLBs / LEs), programmable interconnect, block RAM, and I/O cells. The FLEX 10K family pioneered the embedded array block (EAB) concept, providing dedicated SRAM blocks for memory functions and is recognised as the industry's first SOPC (System-on-a-Programmable-Chip) FPGA platform. Because SRAM-based FPGAs are volatile, the EPF10K30RC240-3 must be configured at every power-up from an external EPROM, flash, or microcontroller. Key features of the EPF10K30RC240-3 include approximately 12,288 bits of distributed RAM, six EAB blocks for dual-port or synchronous memory, multiVolt I/O supporting mixed-voltage interfaces, JTAG (IEEE 1149.1) boundary-scan test support, and in-system programmability via Altera's ByteBlaster or BitBlaster download cables. The exposed thermal pad on the 240-RQFP package enables direct PCB heatsinking for industrial and commercial designs. Combined with 189 usable pins and up to 6 EABs (12,288 memory bits), this device targets medium-density glue logic, bus interface bridging, and prototype ASIC replacement. From an architectural standpoint, the FLEX 10K family uses a continuous FastTrack interconnect with row and column channels driven by the LABs. Each LAB contains eight LEs, each LE consisting of a 4-input LUT, a programmable register, and dedicated carry/chain logic for arithmetic. The embedded array blocks (EABs) provide true dual-port or single-port RAM up to 2,048 bits each, with configurable width/depth. The I/O structure features tri-state buffers, registers, and configurable slew-rate control, making the device well suited to bus and backplane interface designs operating at 5 V CMOS or 3.3 V LVTTL/LVCMOS levels. Typical applications include telecommunications line cards, industrial control glue logic, instrumentation data acquisition pre-processing, retro-computing and legacy PCI/ISA bus interfaces, and ASIC prototyping for medium-complexity state machines. Engineers also use the EPF10K30RC240-3 as a long-life-cycle bridge between parallel buses (e.g. ISA, VME) and modern microprocessors. Designers should pay attention to the 5 V VCCINT requirement: the FLEX 10K family is NOT 3.3 V-tolerant on its core supply, although its I/O ring supports mixed-voltage operation. Always provide a stable POR (power-on-reset) and at least 65 ms of configuration time before driving outputs, and verify the JTAG chain integrity before relying on in-system updates.

An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor device built around configurable logic elements (LEs), a programmable interconnect fabric, and I/O blocks that can be customized to implement arbitrary digital logic. The FLEX 10K family introduced an embedded array block (EAB) architecture that integrates look-up table (LUT)-based logic with dedicated RAM/ROM blocks on a single die - a predecessor to the modern embedded-block-RAM paradigm used in today's high-end FPGAs. Positioned within the broader taxonomy: FPGA -> programmable logic device (PLD) -> digital logic IC -> semiconductor. The FLEX 10K line is historically significant as one of the first "system-on-a-chip" FPGA families. Key features of the EPF10K30RC240-3N include 216 LABs (Logic Array Blocks), 189 user I/Os, 12,288 RAM bits distributed across embedded array blocks, in-system programmability via the Altera (now Intel) ByteBlaster or BitBlaster configuration interfaces, and JTAG (IEEE 1149.1) boundary-scan support. The device supports 3.3V and 5V multi-voltage I/O via banked I/O standards, enabling mixed-voltage interfacing with surrounding logic. From an architecture perspective, the FLEX 10K integrates 1,728 logic elements organized into 216 LABs, each containing 8 LEs. Each LE contains a 4-input LUT, a programmable register, and dedicated carry and cascade chains for high-speed arithmetic and wide fan-in logic. Six embedded array blocks (EABs) each provide 2,048 bits of dual-port RAM, supporting true dual-port and single-port RAM, ROM, and large look-up table functions. The interconnect uses a continuous FastTrack routing fabric with predictable delay for deterministic timing closure. Typical applications for the EPF10K30RC240-3N include legacy telecom interface cards, industrial control glue logic, glue logic for microprocessor-based systems, bus-interface bridges (PCI, ISA, VME), and prototype ASIC replacement. Its 5V tolerance and 189 I/Os make it well suited to systems that need to drive or receive 5V TTL signals directly. When designing with this device, ensure proper decoupling (100 nF + 10 µF per supply pin) and that configuration mode (e.g., PS, AS, JTAG) is selected correctly before applying VCCINT. The 240-RQFP package has a thermal resistance that must be derated against maximum ambient; high-utilization designs may need forced-air cooling.

The EPF10K30RC240-4 is well suited for legacy industrial glue-logic, telecommunication interface bridges, factory automation controllers, and avionics retrofit projects. The 5 V I/O tolerance also makes it compatible with TTL-era bus standards still common in long-lifecycle equipment. Designers migrating legacy Altera designs to modern platforms use it as a stable reference point. When designing, ensure the 5 V supply is well decoupled with bulk + ceramic caps near the exposed pad to manage in-rush during configuration. The exposed thermal pad should be soldered to a sufficient copper pour to keep junction temperature within the -40 °C to +85 °C operating range.

EPF10K30RI208-4 - FLEX 10K FPGA 30K Gates 208-RQFP | Intel / Altera
The Intel / Altera (formerly Altera) EPF10K30RI208-4 is a member of the FLEX 10K family of Field Programmable Gate Arrays (FPGAs) delivering 30,000 gates and 1,728 logic cells in a 208-pin RQFP (Power Quad Flat Pack) package with exposed pad. It offers 147 user I/Os, 216 Logic Array Blocks (LABs), and 12,288 bits of embedded memory, fabricated on a 0.42 µm CMOS process and operating from a 5 V supply. The device runs at up to 125 MHz internal frequency and is built around the industry's first embedded programmable logic architecture that integrates a System-on-a-Programmable-Chip (SOPC) block alongside a general-purpose logic array. What is an FPGA? A Field Programmable Gate Array is a semiconductor IC containing an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and I/O cells that engineers can program to implement custom digital hardware. FPGAs sit above microcontrollers and ASICs in the design complexity hierarchy, offering parallel hardware execution, deterministic timing, and re-programmability for prototyping, low-volume production, and compute acceleration. Key features of the EPF10K30RI208-4 include 30K equivalent gates, 1,728 logic cells, 12,288-bit embedded array block (EAB) memory, 147 user I/O pins, and a 0.6000 ns propagation delay per logic element. The embedded array blocks can be configured as RAM, ROM, or first-in first-out (FIFO) functions, eliminating the need for external memory in many glue-logic designs. The 5 V I/O standard simplifies interface with legacy TTL/CMOS peripherals. The FLEX 10K architecture combines fine-grained logic elements (Logic Elements / LEs) with coarse-grained embedded array blocks (EABs). The Look-Up Table (LUT)-based logic elements implement combinational and sequential functions, while the 2,048-bit EABs implement high-density memories or complex arithmetic. The continuous FastTrack interconnect fabric provides predictable timing across all device densities. Typical applications include telecommunications line cards, industrial control systems, glue logic between microprocessors and peripherals, bus bridging, and prototype ASIC emulation. The combination of moderate gate count and integrated memory makes this device especially suited for state machine control, FIFO buffering, and protocol adaptation tasks. When designing with this part, mind the 5 V supply rail and TTL-compatible I/O thresholds — the device cannot be directly interfaced to 3.3 V logic without level translation. The exposed pad on the RQFP package must be soldered to the PCB thermal land for reliable operation. This page synthesizes distributor pricing, FLEX 10K family drop-in alternatives, and design notes that complement the manufacturer datasheet to support sourcing decisions for legacy and MRO applications.

A field-programmable gate array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the designer can reconfigure after manufacture to implement arbitrary digital logic. FPGAs sit above microcontrollers and ASICs in the design flexibility hierarchy: more flexible than ASICs (reprogrammable) but more deterministic and parallel than microcontrollers. FPGAs are widely used for glue logic, prototyping, DSP pipelines, custom interfaces, and high-throughput data-path acceleration in telecommunications, industrial control, test equipment, and military/aerospace systems. Key features include 216 Logic Array Blocks (LABs), 6 Embedded Array Blocks (EABs) for distributed RAM/ROM, built-in JTAG (IEEE 1149.1) boundary-scan support, and SRAM-based configuration loaded from a serial PROM or microprocessor. The device supports MultiVolt I/O for interfacing to 3.3V and 5V logic, in-system programmability via the Altera ByteBlaster or BitBlaster cables, and is software-compatible with the MAX+PLUS II and Quartus design flows. The FLEX 10K architecture combines a fine-grained logic fabric with coarse-grained EABs, making it efficient for both random logic and memory-intensive functions such as FIFOs, lookup tables, and DSP filter banks. Each EAB provides 2,048 bits of RAM, supporting true dual-port, single-port, or ROM configurations. Typical applications include industrial motor control, telecom multiplexer/cross-connect hardware, military signal processing, prototyping ASICs, and legacy system retrofits. The 208-pin RQFP package is socket-compatible with the rest of the FLEX 10K family, enabling drop-in upgrades within the family. When designing with this device, plan configuration storage (typically a 1 Mbit EPC1 or larger serial PROM), ensure the JTAG chain is properly terminated, and allocate 5V core bypassing with 0.1 µF + 10 µF capacitors near each supply pin.

EPF10K30RI240-4 - FLEX 10K FPGA 30K Gates 1728 Cells 240-RQFP | Intel
The Intel (formerly Altera) EPF10K30RI240-4 is a member of the FLEX 10K family of Field Programmable Gate Arrays (FPGAs) built on a 0.42 µm CMOS SRAM process, delivering 30,000 typical gates, 1,728 logic cells, and 12 kbit of embedded memory in a 240-pin RQFP (Power Quad Flat Pack) package with exposed pad. It provides 189 user I/Os, 216 Logic Array Blocks (LABs), an internal frequency up to 125 MHz, and propagation delay around 0.6 ns, designed for 5 V core operation. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the high integration of a gate array with the design flexibility of in-system programmability. Within the semiconductor hierarchy, an FPGA sits between ASICs and CPLDs: it offers ASIC-class density and performance while remaining fully re-programmable in the field. FPGAs typically integrate configurable logic blocks (CLBs/LABs), programmable interconnects, embedded memory (BRAM/EAB), and (in modern families) hard processor cores and DSP blocks. Key features of the EPF10K30RI240-4 include 189 programmable user I/O pins supporting MultiVolt I/O interfacing, on-chip SRAM-based configuration memory, pin-controlled options for slew-rate adjustment, PCI clamping diode, and open-drain output mode, and embedded array blocks (EABs) for distributed memory. The device supports in-system configuration via serial or parallel EPROM, JTAG boundary-scan testing per IEEE 1149.1, and is offered in a commercial 0 °C to 70 °C operating temperature grade. Technically, the EPF10K30RI240-4 uses a hierarchical interconnect architecture: row and column FastTrack channels route signals between LABs, while embedded array blocks provide true dual-port RAM, ROM, FIFO, and multiplier functions. The 5 V VCCINT supply and MultiVolt VCCIO rails (3.3 V / 5 V) make it compatible with both 5 V TTL and 3.3 V logic systems, simplifying mixed-voltage board design. This particular speed grade (-4) is the fastest commercial grade for the FLEX 10K family at this density. Typical applications include telecommunications line cards, industrial control and instrumentation, glue-logic integration for embedded systems, prototyping of ASIC designs, image and signal processing front-ends, and legacy 5 V system upgrades. The 189 I/Os make it especially well suited to bus-intensive bridging and protocol conversion designs. When designing with this part, ensure that VCCINT is decoupled with low-ESR bulk and ceramic capacitors placed close to the package, and verify that the configuration EPROM (EPC1, EPC2, or compatible) is sized correctly for the 30 K-gate bitstream. The exposed thermal pad must be soldered to a sufficient copper pour for heat dissipation.

EPF10K30RI240-4N - 30K FLEX-10K FPGA, 189 I/O, 240-BFQFP | Intel
The Intel (formerly Altera) EPF10K30RI240-4N is a member of the FLEX 10K family of SRAM-based Field-Programmable Gate Arrays (FPGAs), delivering approximately 30,000 typical gates and 1,728 logic elements (LEs) organized into 216 Logic Array Blocks (LABs) with 12,288 bits of embedded memory. Housed in a 240-pin BFQFP (RQFP) exposed-pad package, this -4 speed-grade device operates from a 5 V core supply with MultiVolt I/O support and provides 189 user I/O pins for high-density glue-logic and bus-interface designs. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs), programmable interconnects, and I/O cells, all defined by a user-loaded SRAM configuration bitstream. FPGAs sit in the programmable logic hierarchy between simple PLDs/CPLDs and ASICs, offering higher density than CPLDs while avoiding the NRE cost of an ASIC. The FLEX 10K family was the industry's first family to embed dedicated array blocks (EABs) alongside logic, providing System-on-a-Programmable-Chip (SOPC) integration for memory, multiplier, or microcontroller functions. Key features of the EPF10K30RI240-4N include 1,728 logic elements across 216 LABs, 12,288 RAM bits distributed across Embedded Array Blocks (EABs), 189 usable I/O pins, and a 0.42 µm CMOS SRAM process. The device supports in-system JTAG (IEEE 1149.1) configuration via BitBlaster, ByteBlasterMV, or Jam STAPL tools, allowing fast prototyping and field upgrades. Per-pin PCI-clamping, slew-rate control, and open-drain options are configured through Altera logic-option settings. Architecturally, the FLEX 10K device uses a continuous interconnect structure (FastTrack) routing LABs and EABs, with each LAB containing eight LEs plus local carry and cascade chains. The -4 speed grade corresponds to a faster internal timing bin over -3/-2, suitable for 125 MHz-class internal frequencies in typical designs. The MultiVolt I/O feature lets VCCIO be tied to 3.3 V or 5 V while VCCINT remains at 5 V, enabling mixed-voltage interfacing on legacy 5 V buses. Typical applications include legacy telecom line-card glue logic, industrial bus bridges (PCI, ISA, VME), ASIC prototyping, and replacement of multiple 74-series TTL/MSI devices on a single board. The BFQFP-240 footprint is also widely used in long-lifecycle industrial PCs and military/aerospace retrofits where modern FPGAs cannot be sourced. Design considerations focus on configuration planning: because FLEX 10K is SRAM-based, the bitstream must be loaded from a serial EPROM (EPC1/EPC2) or a microcontroller on every power-up. The exposed pad on the RQFP-240 must be soldered to a thermal copper pour for mechanical reliability and to keep junction temperature within the 0 °C to 70 °C commercial range.

The device uses a hierarchical interconnect architecture with embedded array blocks (EABs), look-up table (LUT)-based logic elements, and continuous FastTrack routing. Configuration is loaded from a serial PROM or microcontroller into on-chip SRAM cells, allowing unlimited in-system reconfiguration. MultiVolt I/O allows it to interface with both 3.3 V and 5 V peripherals on the same board, an important feature during the transition era of mixed-voltage logic. Typical applications of the EPF10K40RC208-3N include glue logic replacement, custom peripheral controllers, industrial bus bridges, telecommunications line-card interface logic, and legacy industrial/embedded glue. It is also widely used to bridge legacy TTL/CMOS logic blocks and as a prototyping vehicle before migrating to a structured ASIC. Design considerations include ensuring the JTAG configuration chain supports 5 V signaling, using a stable 5 V core supply, and following the MAX+PLUS II or Quartus design flow (where the EPF10K40 is still supported for legacy projects). Because this part has been in production since the late 1990s, lifecycle status should be confirmed before any new commitment. This page consolidates distributor pricing, drop-in replacement candidates, and design notes that complement (but do not replace) the manufacturer datasheet and legacy configuration manuals.
EPF10K40RC208-4 - Flex 10K FPGA, 40K Gates, 147 I/O, RQFP-208 | Intel
The Intel EPF10K40RC208-4 is a member of the FLEX 10K family of Field Programmable Gate Arrays (FPGAs), delivering approximately 40,000 typical gates with 2,304 logic elements housed in a 208-pin RQFP (Plastic Quad Flat Pack) package with exposed pad. The device integrates a high-performance embedded array block (EAB) architecture with 16,384 bits of RAM distributed across 288 logic array blocks, operating from a 5 V supply at up to 125 MHz internal frequency.

The exposed-pad 208-pin RQFP package aids thermal dissipation while keeping the package compatible with existing FLEX 10K board designs. Architecturally, the FLEX 10K device combines a fine-grained logic fabric with coarse-grained EABs that double as 256×8 or 512×4 dual-port RAM blocks. This hybrid approach allows efficient implementation of both random logic and datapath/memory functions on a single chip, reducing the typical two-chip (FPGA + SRAM) solution to one. Configuration is loaded from a serial or parallel PROM at power-up via the built-in SRAM-based logic. Typical applications include telecommunications line cards, industrial control logic replacement, glue logic for legacy systems, ASIC prototyping, and embedded controllers. The wide gate count also suits digital signal processing front-ends and bus-interface bridging between microprocessors and peripherals. When designing with the EPF10K40RC208-4, ensure proper decoupling (0.1 µF + 10 µF bulk near each VCC pin) and verify JTAG chain integrity. The 5 V supply rail and 0.42 µm process mean the device is not directly pin-compatible with 3.3 V Cyclone or MAX families; a level-shifting interface is required when bridging to modern logic.

It supports up to 189 user I/Os and operates at a maximum internal frequency of 125 MHz on a 0.42 µm CMOS process at 5 V supply. An FPGA (Field Programmable Gate Array) is a programmable logic device whose architecture consists of an array of configurable logic blocks (LABs) interconnected by a programmable routing fabric and surrounded by programmable I/O cells. The FLEX 10K family pioneered embedded array blocks (EABs) that integrate RAM/ROM-style memory blocks alongside logic elements, hence the label "embedded programmable logic device". Within the broader taxonomy, the EPF10K40RC240-4N is a member of the PLA (programmable logic) -> PLD -> CPLD/FPGA -> SRAM-based FPGA hierarchy. Key features include 288 logic array blocks (LABs), 189 maximum user I/Os, 5 V VCCINT/VCCIO operation, JTAG (IEEE 1149.1) boundary-scan testing support, in-system programmability via the Altera ByteBlasterMV or BitBlaster cable, and 0.42 µm CMOS technology. The "-4" speed grade places it in the moderate-performance tier within the FLEX 10K family, and the "N" suffix indicates a lead-free / RoHS-compliant commercial-grade part rated for 0 °C to 85 °C operation. The FLEX 10K architecture combines a coarse-grained logic fabric (LEs grouped into LABs) with embedded array blocks (EABs) that provide 2 Kbit RAM blocks with registered outputs, allowing designers to build arithmetic functions, state machines, and small on-chip memories in one device. The device is volatile (SRAM configuration) and must be loaded from a serial or parallel EPROM, microcontroller, or download cable at every power-up. Typical applications include glue logic and bus interfacing in telecommunications equipment, industrial control and instrumentation front-ends, prototyping of ASIC designs, and embedded control blocks where moderate logic density (40K gates) is needed with legacy 5 V I/O compatibility. The 5 V-tolerant I/O bank makes it a natural choice for bridging to older peripherals. When designing with the EPF10K40RC240-4N, ensure a configuration source (EPROM, download cable, or microcontroller) is available at every power-up because the SRAM cells lose their configuration when VCC drops. Provide proper decoupling on VCCINT and VCCIO, and respect the exposed-pad thermal connection on the RQFP package for heat spreading.

This hybrid logic-plus-memory architecture allows single-chip implementation of wide datapath functions such as FIFOs, DSP building blocks, and bus controllers without external memory devices. Typical applications for the EPF10K50EFC484-2 span industrial control systems, telecommunications line cards, PCI bus interfaces compliant with PCI Local Bus Specification Revision 2.2 at 33 MHz and 66 MHz, test and measurement equipment, and legacy upgrade replacements. With 220 user I/Os, the device is well suited to bus-intensive designs such as memory controllers, bridge chips, and protocol converters. When designing with this part, note that Altera/Intel has marked the FLEX-10KE family as obsolete in long-term product roadmaps, so this component is recommended for legacy maintenance and existing design support rather than new designs. New designs should consider Cyclone IV, Cyclone V, or MAX 10 devices as modern successors. This page synthesizes distributor inventory, lifecycle status, and practical cross-reference notes for engineers maintaining legacy FLEX-10KE designs or sourcing replacements for end-of-life inventory.

Architecturally, an FPGA sits within the broader hierarchy of programmable logic devices (PLDs), between simple Complex Programmable Logic Devices (CPLDs) and high-end Application-Specific Integrated Circuits (ASICs). Within the programmable logic family tree, FPGAs are subdivided by architecture into SRAM-based, antifuse-based, and Flash-based variants; the FLEX 10KE family belongs to the SRAM-based, volatile-configuration segment, requiring a configuration EPROM or controller to load the bitstream at every power-up. The part number breaks down as follows: EPF10K = FLEX 10K family; 50 = 50K typical gates; E = Enhanced (10KE variant); Q = PQFP package; C = Commercial temperature grade (0 °C to +70 °C); 208 = 208 pins; -3 = speed grade. The device supports a core supply of 2.3 V to 2.7 V (2.5 V typical) with 3.3 V or 5.0 V tolerant I/O banks, a maximum internal frequency near 166.67 MHz, and 360 LABs (Logic Array Blocks). Each LAB contains 8 Logic Elements, providing efficient implementation of wide combinational and registered functions. The device is supplied in a 28 mm × 28 mm body, 208-BFQFP (also called PQFP) tray package. Typical applications include bus-bridging ASIC prototyping, glue logic in telecom backplane designs, industrial control interfaces, and image-processing front ends. The rich EAB memory and four FastTrack interconnect rows make this device well suited to high-speed datapath pipelines. When designing with this device, ensure your board hosts a configuration source (EPC1/EPC2 or a microcontroller) and plan I/O banking for mixed 3.3 V/5 V peripherals. For new designs, consider Cyclone or Cyclone II as modern, non-obsolete alternatives; the FLEX 10KE family is end-of-life.
EPF10K50EQC240-1 - FLEX 10KE 50K FPGA 240-PQFP | Intel
The Intel EPF10K50EQC240-1 is a member of the FLEX 10KE family of SRAM-based Field-Programmable Gate Arrays, delivering 50,000 typical gates and 2,880 logic elements in a 240-pin Plastic Quad Flat Pack (PQFP) with 189 user I/Os. Built on a 0.22 µm CMOS process and operating from a 2.5 V nominal supply (2.3 V min, 2.7 V max), the device combines a logic array block architecture with embedded array blocks for System-on-a-Programmable-Chip (SOPC) integration, reaching internal performance of up to 250 MHz. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) containing an array of configurable logic blocks (CLBs), programmable interconnect, and programmable I/O cells that engineers can configure after manufacturing to implement custom digital circuits. Within the broader hierarchy, FPGAs sit above simple PLDs (PALs, GALs) and below application-specific integrated circuits (ASICs); the FLEX 10KE family in particular pioneered embedded memory and embedded array blocks, making it one of the first true SOPC devices where memory and logic coexist on a single die. The "-1" speed grade of EPF10K50EQC240 designates the slowest of three commercial speed grades offered in this family. Key features include 40,960 bits of embedded RAM distributed across EABs, 360 Logic Array Blocks (LABs), 189 usable I/O pins, in-system programmability via the IEEE 1149.1 JTAG interface, and 0.22 µm SRAM-based configuration cells that allow unlimited reconfiguration. The device supports multi-voltage I/O standards and offers low-power consumption relative to equivalent ASIC gate counts. Its 240-pin PQFP packaging provides gull-wing leads suitable for surface-mount assembly and rework. Typical applications span communications infrastructure, industrial automation, test and measurement instrumentation, and legacy embedded systems requiring 50K-gate-class programmable logic. The wide I/O count (189) makes EPF10K50EQC240-1 particularly suited to bus-intensive designs such as PCI bridges, custom microcontroller peripherals, and DSP co-processing front ends. When designing with EPF10K50EQC240-1, ensure a stable 2.5 V core supply with sufficient decoupling near the VCC pins; the SRAM configuration cells are volatile and require a configuration device or microprocessor on every power-up. PCB designers should follow PQFP thermal guidelines and provide adequate ground returns for the 189 high-speed I/O transitions.

EPF10K50EQC240-1N - FLEX 10KE FPGA 50K Gates 2880 Cells 240-PQFP | Altera
The Altera (Intel) EPF10K50EQC240-1N is a FLEX 10KE family Field-Programmable Gate Array (FPGA) with 50K equivalent gates, 2880 logic elements, and 40960 bits of embedded memory, housed in a 240-pin Plastic Quad Flat Pack (PQFP / BFQFP) package. The device operates from a 2.5V core supply, supports 189 user I/O pins, and is built on a 0.22 µm CMOS SRAM process. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device that contains an array of configurable logic blocks, programmable interconnect, and I/O cells, all of which can be reconfigured by the designer after manufacture. FPGAs sit in the broader taxonomy of programmable logic device (PLD) -> logic IC -> integrated circuit (IC) -> semiconductor. Unlike ASICs, FPGAs allow rapid prototyping and field upgrades without fabrication cycles, making them ideal for glue logic, custom state machines, and glue between microprocessors and peripherals. Key features of the EPF10K50EQC240-1N include 360 Logic Array Blocks (LABs), 50K gates of logic capacity, 2880 logic cells, 12 Embedded System Blocks (ESBs) providing 40,960 bits of RAM, true dual-port RAM support, multi-volt I/O supporting 2.5V/3.3V/5V interfacing, in-system programmability via the serial passive (PS) configuration mode, and JTAG boundary-scan test support per IEEE 1149.1. The part is specified over the commercial 0 °C to +85 °C temperature range, with internal performance capable of 250 MHz operation. Architecturally, the FLEX 10KE device uses a continuous, fine-grained interconnect called the FastTrack Interconnect, with each row and column of logic elements routed through this interconnect to deliver predictable timing. The 0.22 µm process and 2.5V core allow low static and dynamic power dissipation while supporting fast propagation delays of approximately 0.5 ns per logic element. Typical applications include telecommunications line-card glue logic, industrial control and instrumentation interfaces, PCI bus bridges, video processing front-ends, custom peripheral controllers for legacy microprocessors, and prototyping for ASIC replacement. The 189 user I/Os and multi-volt capability make the device well suited to bridging 5V peripherals to 3.3V or 2.5V ASICs and processors. When designing with this part, note that the configuration scheme must be selected (e.g., PS, AS, JTAG) and the Quartus / MAX+PLUS II tool flow used. The 240-pin PQFP footprint requires through-hole-style soldering or a socket; consider the FQFP variant (EPF10K50EQI240-1N) only if industrial temperature range is required, not for package differences. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the standalone manufacturer datasheet, supporting both procurement engineers and FPGA designers.
EPF10K50EQC240-2 - 50K FLEX-10KE FPGA, 240-PQFP | Intel
The Intel (formerly Altera) EPF10K50EQC240-2 is a member of the FLEX-10KE family of Field-Programmable Gate Arrays (FPGAs) that integrates 2,880 logic elements and 40,960 system gates into a 240-pin Plastic Quad Flat Pack (PQFP-240) package. Built on a 0.22 µm CMOS process and rated for commercial-grade operation, this device combines Look-Up Table (LUT)-based logic with embedded array blocks (EABs) to deliver up to 200 MHz core performance from a 2.5 V supply. The suffix codes communicate key variants: 'E' denotes the enhanced 10KE architecture, 'QC' indicates the PQFP-240 package with commercial temperature grade, and '240-2' specifies the 240-pin PQFP at speed grade -2. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that lets designers implement custom digital circuits by configuring an array of configurable logic blocks (CLBs), interconnect, and I/O cells. The FLEX-10KE family sits in the broader hierarchy of programmable logic: programmable logic device -> CPLD/FPGA -> SRAM-based FPGA -> embedded-block FPGA (FLEX 10KE). EABs provide on-chip dual-port RAM and ROM blocks that accelerate arithmetic, FIFO, and DSP-style datapaths without consuming general-purpose logic. Key features include 189 user I/O pins, 360 Logic Array Blocks (LABs), 12 embedded array blocks, and a typical standby current under 0.5 mA. The device supports in-system programmability via an IEEE 1149.1 JTAG interface and configuration via a serial EPROM, making it suitable for high-volume production. The PQFP-240 package provides gull-wing leads on a 0.5 mm pitch with body dimensions of 34.6 × 34.6 mm, easing PCB routing on standard 4-layer boards. Architecturally, the EPF10K50E uses SRAM configuration cells combined with a fine-grained LAB fabric and column-style EAB rows. Each LAB contains 8 logic elements with carry-chain and cascade-chain support, while EABs offer up to 2 Kbits of RAM each with configurable width. Compared with first-generation FLEX 10K, the 'E' revision doubles EAB RAM density, lowers core voltage to 2.5 V, and improves timing margin for 66 MHz PCI designs. Typical applications include PCI bus interfaces (33/66 MHz), telecommunications glue logic, industrial control state machines, glue logic for ASIC prototyping, and legacy embedded computing. The wide I/O count and generous on-chip memory make it a strong fit for multi-bridge or multi-protocol designs where several bus controllers coexist on one chip. When designing with this part, attention to decoupling (at least 0.1 µF + 10 µF per VCC pin pair), JTAG chain integrity, and configuration mode selection (PS, AS, JTAG) is critical. Designers migrating to newer Intel Cyclone or MAX families should treat the EPF10K50E as a legacy device and validate software support via the Quartus Prime toolchain.
