The 'I' speed grade places it in the mid-range of FLEX 6000 timing, while the 'N' suffix indicates a lead-free (Pb-free) assembly. Architecturally, the FLEX 6000 family uses Altera's Lab/Embedded Array Block structure. Each Logic Array Block (LAB) contains ten Logic Elements, each consisting of a 4-input LUT, a programmable register, and dedicated carry chain logic for arithmetic operations. This architecture makes the EPF6024 well-suited for high-speed glue logic, register-intensive datapath functions, and interface bridging applications. Typical applications include telecommunications line cards, industrial control systems, peripheral interface bridging, and legacy ASIC replacement. The 172 MHz internal clock rate supports common protocols such as PCI, UART, and high-speed parallel buses. When designing with this device, ensure that the JTAG chain is properly terminated and that configuration data is sourced from a stable EEPROM or processor. Designers should also verify that downstream tools (Quartus II or MAX+PLUS II) support the device before starting a new project.

The device operates from a 3.3 V core supply with 5.0 V I/O tolerance, satisfying low-power requirements for notebook computers and battery-operated equipment. The FLEX 6000 architecture combines a continuous, high-performance routing network with fine-grained logic elements, enabling predictable timing closure for designs up to 24,000 gates. Its 4 dedicated input pins feed the global clock and clear networks, while the 199 user I/Os can be configured per-pin as input, output, or bidirectional with slew-rate control and tri-state buffering. Typical applications for the EPF6024AQI240-2 include glue-logic integration on legacy 5V/3.3V motherboards, PCI bus interfaces, peripheral controllers, telecommunications line cards, digital signal processing co-processors, and industrial control systems where the industrial temperature range is required. The PQFP-240 footprint remains widely supported by through-hole-compatible socket adapters for prototyping. When designing with this FPGA, ensure that the Quartus II or MAX+PLUS II design toolchain matches the '-2' speed grade in the device selection. The configuration scheme (PS, PPS, or JTAG) must be selected during board design because FLEX 6000 devices do not retain configuration when power is removed - a separate configuration memory device is required.

The 240-pin PQFP footprint enables simpler rework and breadboarding compared with fine-pitch BGA alternatives, an important consideration for legacy industrial designs. Architecturally, the FLEX 6000 device uses Altera's patented continuous interconnect scheme with embedded array blocks (EABs) used as RAM/ROM. The part is fabricated on a CMOS process and operates from a 5.0 V core supply with multi-voltage I/O support. Configuration is loaded from a serial or parallel PROM over a dedicated data path, making board-level bring-up straightforward. Typical applications include industrial control glue logic, parallel I/O expansion and bus interfacing, prototype-to-production ASIC replacement, motor-control sequencing, legacy telecom backplane glue logic, and test instrumentation I/O conditioning. The 240-pin PQFP package is also favored where socket-based field replacement is required. Design consideration: The EPF6024AQI240-3 is an older FLEX 6000 device, and Intel/Altera long-term support is limited. Designers building new products should consider Cyclone or Cyclone II as modern equivalents, while keeping the FLEX 6000 family for legacy repair and second-source maintenance.

EPF6024ATC100-10 - FLEX 6000 24K Gates FPGA | Altera | TQFP-100
The Altera EPF6024ATC100-10 is a member of the FLEX 6000 family of CMOS programmable logic devices, offering 24,000 typical gates (16,000 logic gates equivalent) in a 100-pin TQFP (TC100) surface-mount package with -10 speed grade. The device is fabricated on a 0.42 um CMOS SRAM-based process and operates from a 3.3V core supply with 5.0V tolerant I/O, making it drop-in compatible with the older 5V-only MAX 7000 family while consuming substantially less power. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the density of gate arrays with the in-system reprogrammability of SRAM. Within the broader semiconductor taxonomy, an FPGA belongs to: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit -> semiconductor. FPGAs are used to implement arbitrary digital logic functions, glue logic, bus bridges, state machines, and parallel data-path circuits, sitting between fixed-function ASICs (high NRE, low unit cost) and small CPLDs (low density, non-volatile) in the design trade-off space. Key features of the EPF6024ATC100-10 include 1,960 logic elements (LEs), 24,192 RAM bits of embedded memory, four embedded array blocks (EABs) each configurable as 2Kx8 / 4Kx4 / 8Kx2 / 16Kx1 RAM or ROM, 80 maximum user I/O pins, and FastTrack continuous routing interconnect. Per the manufacturer datasheet, the device supports in-system configuration via the passive serial (PS), passive parallel asynchronous (PPA), passive parallel synchronous (PPS), and active serial (AS) configuration schemes with optional data compression for faster configuration. Architecturally, each LE contains a 4-input look-up table (LUT), a programmable register, a carry chain for fast adders, and a cascade chain for wide fan-in functions. The four EABs each provide 2K bits of true dual-port RAM with byte enables, enabling efficient FIFO, look-up-table, and small-cache implementations without consuming external LE memory. The FastTrack interconnect provides predictable, delay-driven routing across row and column channels, simplifying timing closure compared with segmented architectures. Typical applications include industrial control glue logic, telecom line-card bus interfaces, legacy peripheral bridging (PCI-to-ISA, UART-to-ISA), DSP co-processing front-ends, and digital instrumentation. The wide 5V tolerant I/O makes it a popular choice as a drop-in upgrade for 5V MAX 7000 designs that need higher density without redesigning the power tree. Designers should note that the EPF6024ATC100-10 is in the Altera FLEX 6000 family with -10 speed grade; the higher -2 and -3 speed grades (when available) offer improved Fmax but require verification against timing constraints. Quiescent supply current is dominated by I/O switching, so decoupling must include 0.1 uF X7R ceramics per VCCIO/VCCINT pin pair plus a bulk 33 uF tantalum near the supply pins.
EPF6024ATC114-3 - FLEX 6000 FPGA 24K Gates | Altera
The Altera (now Intel) EPF6024ATC114-3 is a member of the FLEX 6000 family of SRAM-based programmable logic devices, providing approximately 24,000 equivalent gates of logic capacity in a 114-pin TQFP package. It is a low-density, low-cost FPGA optimized for glue-logic, bus-interface, and high-volume consumer/industrial applications where ASIC replacement economics matter more than raw logic density. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit containing configurable logic blocks (CLBs), programmable routing, and I/O cells that engineers can program after manufacture using a hardware description language (HDL). In the broader taxonomy, FPGAs belong to programmable logic devices (PLDs), sitting alongside CPLDs and structured ASICs; the FLEX 6000 family represents Altera's earlier-generation, SRAM-based, look-up-table (LUT) architecture that was widely adopted in the late 1990s and early 2000s for ASIC prototyping and low-density glue logic. Key features of the EPF6024ATC114-3 include approximately 24,000 typical gates, 1,960 logic elements (LEs), 117 user I/O pins, and SRAM-based configuration with a 5.0 V tolerant I/O supply option. The device is built on a 0.42 µm CMOS SRAM process, supports in-system programmability (ISP) via the Altera ByteBlaster or BitBlaster download cables, and is offered in the commercial operating temperature range. Architecturally, the FLEX 6000 device uses a row-and-column interconnect structure with embedded array blocks (EABs) for memory and arithmetic functions. Each logic element contains a 4-input look-up table (LUT), a programmable flip-flop, and fast carry-chain logic for arithmetic. This is a different architecture from MAX 7000 (CPLD) and from the more modern Cyclone series, so designers porting designs between families must re-target HDL and re-pin assignments. Typical applications include bus-interface bridging, peripheral controllers, ASIC prototyping, industrial control glue logic, and legacy telecommunications backplane interfaces. The wide operating temperature range and PQFP/TQFP packaging also make it suitable for industrial automation systems and embedded instrumentation where surface-mount rework is straightforward. When designing with this part, note that the EPF6024ATC114-3 is now in an obsolete/EOL lifecycle state. Engineers targeting new designs should consider the modern Cyclone series or MAX II CPLDs, while existing production designs should verify long-term supply arrangements with distributors and consider last-time-buy opportunities. Configuration must be loaded from an external serial PROM at power-up because the SRAM-based configuration is volatile. This page synthesizes verified distributor inventory, drop-in pin-compatible alternatives from the FLEX 6000 family, and practical design notes for legacy ASIC replacement, providing context not aggregated in any single manufacturer or distributor datasheet.

The device is built on a 0.42 µm CMOS process and operates at 3.3 V core with 5.0 V tolerant I/O capability via pull-up resistors. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and programmable I/O cells. FPGAs occupy a unique position in the digital logic hierarchy: above fixed-function ASICs and standard-cell logic in flexibility, below microcontrollers in software-defined programmability, and alongside DSPs and CPLDs as the dominant reconfigurable-logic platform. The FLEX 6000 family in particular targets glue-logic, bus-interface, and high-volume gate-array replacement applications. Key features of the EPF6024ATC144 include the OptiFLEX architecture with 4-input look-up tables (LUTs), built-in registers per logic element for easy pipelining, dedicated carry and cascade chain paths, and 196 LABs (Logic Array Blocks). The device supports in-system programmability via the IEEE 1149.1 JTAG interface and offers MultiVolt I/O for interfacing between 3.3 V and 5.0 V systems. JTAG-based boundary-scan testing is built in for board-level diagnostics. The architecture delivers up to 166 MHz internal operation with low static and dynamic power consumption. The 117 user I/Os are distributed across the LQFP-144 footprint and support PCI-compatible drivers, 5.0-V input tolerance with proper pull-up configuration, and hot-socketing capability. Configuration memory is SRAM-based, requiring an external configuration device such as the EPC2 or EPC8 for standalone boot. Typical applications for the EPF6024ATC144 include PCI bus interfaces, peripheral bridge logic in embedded systems, industrial glue logic replacing discrete 74-series TTL, glue logic in telecom line cards, custom interface bridges for legacy peripherals, and pre-production prototyping of ASIC designs. Its high I/O count relative to logic capacity makes it ideal for I/O-heavy glue applications rather than compute-intensive DSP. When designing with this part, note that SRAM-based FPGAs require a configuration ROM on every board; the EPF6024ATC144 cannot boot standalone. A 100 µF bulk capacitor plus 0.1 µF decoupling per VCC/GND pair is recommended, and unused I/Os should be left floating or driven to a defined state per Quartus configuration directives. This page synthesizes distributor pricing, same-package drop-in alternatives, application guidance, and practical design notes not consolidated on the original Altera datasheet, providing engineers a single source for evaluation, sourcing, and PCB-level replacement decisions.

The device supports 3.3 V LVTTL/LVCMOS I/O standards and exposes JTAG (IEEE 1149.1) boundary-scan pins for board test access. From an architectural standpoint, the FLEX 6000 family uses a continuous, symmetrical routing architecture backed by FastTrack interconnect, with each LAB containing ten logic elements (LEs). Configuration data is loaded serially or via the dedicated configuration port, and the design flow uses the legacy MAX+PLUS II or Quartus (legacy device support) toolchain. Typical applications for the EPF6024ATC144-1 include industrial control glue logic, parallel-to-serial bus bridges, legacy peripheral emulation, ASIC prototyping in cost-sensitive systems, and avionics upgrades where a pin-compatible 3.3 V FPGA is required. Today the part is generally sourced from the secondary/aftermarket channel and used to sustain long-life equipment. Designers should note that FLEX 6000 devices require an external configuration EPROM (such as the EPC2 or EPC8) or a microcontroller-driven configuration scheme; the FPGA itself does not retain configuration through power cycles. Verify timing closure using the MAX+PLUS II timing analyzer or Quartus legacy support tools, and ensure the JTAG chain is properly terminated for board-level testability.

What is an FPGA? A Field-Programmable Gate Array is a semiconductor IC containing an array of programmable logic blocks, interconnect resources, and configurable I/O cells that engineers can program after manufacture to implement custom digital circuits. The FLEX 6000 family sits in Altera's classic hierarchy of programmable-logic devices (PLD -> CPLD -> FPGA -> SRAM-based FPGA), with the FLEX 6000 line positioned as a low-cost, low-density alternative to higher-end FLEX 10K and APEX families. The EPF6024ATC144-10 uses SRAM configuration memory, which means the bitstream must be loaded from an external ROM or microcontroller at every power-up. Key features of the EPF6024ATC144-10 include 24,000 typical gates, 1,960 logic elements, 117 maximum user I/O pins, JTAG (IEEE 1149.1) boundary-scan support, and on-chip SRAM-based configuration memory.

Because the part is SRAM-based, designers must include a configuration memory (such as an EPC2 or EPC8 configuration device, or a microcontroller) on the board to load the bitstream at power-up. Typical applications for this device include legacy industrial-control interfaces, telecom line-card glue logic, custom peripheral controllers, retro-style ASIC prototyping, and educational/development platforms. Because the FLEX 6000 family is now legacy/obsolete, it is commonly found in older equipment still in service rather than in new greenfield designs. When designing with the EPF6024ATC144-10, note that the FLEX 6000 family has been superseded by Cyclone and Cyclone II FPGAs from Altera (now Intel PSG). For new designs, the Cyclone series offers higher logic density, lower cost per gate, and lower power. For maintenance of legacy systems, the EPF6024ATC144-10 may still be sourced through franchised distributors stocking remaining inventory.

The Altera (now Intel) EPF6024ATC144-10N is a member of the FLEX 6000 family of SRAM-based Field-Programmable Gate Arrays, providing 1960 logic elements organized as 196 Logic Array Blocks (LABs), 117 user I/O pins, and housed in a 144-pin TQFP (T144) plastic package with a speed grade of -10 (10 ns pin-to-pin delay class). It is fabricated on a 5 V CMOS process with on-chip flash/EPROM configuration support and operates over the commercial 0 C to +70 C junction range. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit built around an array of configurable logic blocks (CLBs or LABs), programmable interconnect, and I/O cells that the user can define after manufacturing. The FLEX 6000 family sits in Altera's older programmable-logic hierarchy between the classic MAX series and the high-density FLEX 10K/Stratix lines, targeting glue-logic replacement, bus interface bridging, and small-to-medium state-machine consolidation. As a programmable logic device (PLD) family, the EPF6024ATC144-10N belongs to the broader semiconductor category of logic ICs. Key features include 1960 logic elements, 117 user I/O pins, built-in cascade and carry chains for high-speed arithmetic and wide-input functions, JTAG-based boundary-scan testability, and multi-voltage I/O support allowing mixed 5.0 V / 3.3 V / 2.5 V interface levels. The -10N suffix indicates a -10 speed grade and lead-free (Pb-free) assembly, with the trailing N denoting industrial-temperature material set in some supplier catalogs. The architecture combines four-input look-up tables (LUTs), dedicated carry chains for fast adders and counters, and cascade chains for wide fan-in functions such as equality comparators. Each LAB contains 10 logic elements (LEs), and dedicated row/column interconnect minimizes routing delay. Embedded SRAM is not part of the FLEX 6000 family, distinguishing it from FLEX 10K; configuration is loaded from external EPROM, flash, or controller over a serial or parallel interface. Typical applications include bus-interface bridges (e.g., ISA-to-PCI glue logic), peripheral controllers in industrial embedded boards, custom state machines in legacy telecom equipment, prototype ASIC replacement, and parallel I/O expansion for legacy microprocessors. The 144-pin TQFP package is footprint-compatible across the EPF6024ATC144 speed-grade family (-3, -1, -10), enabling drop-in PCB reuse when migrating between speed grades. When designing with this device, plan for an external configuration memory (serial EEPROM or parallel EPROM) because the FLEX 6000 family is SRAM-based and loses its bitstream on power-down. Observe the 5.0 V core supply requirement (VCCINT), use decoupling per the datasheet's reference design, and verify I/O bank voltages against your bus partner before PCB layout. This page consolidates drop-in speed-grade alternatives, parametric comparisons, and practical design considerations not always gathered in the original Altera datasheet.
EPF6024ATC144-11 - FLEX 6000 FPGA 24K Gates 117 I/O 144-LQFP | Intel
The Intel EPF6024ATC144-11 is a member of the FLEX 6000 programmable logic device family, providing 24,000 gates of logic capacity in a 144-pin LQFP package with 117 user I/O pins and 1,960 logic elements organized in 196 Logic Array Blocks (LABs). It operates with a -11 speed grade, indicating the timing bin within the family, and uses SRAM-based configuration cells that require an external configuration device. According to Altera FLEX 6000 datasheet literature, this device family is built on a 5V SRAM process and supports in-system programmability through the JTAG-compatible ByteBlaster or BitBlaster interfaces, which enables iterative design updates without removing the part from the board. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs), programmable interconnect, and programmable I/O cells. The hierarchy in the broader taxonomy is: FPGA -> programmable logic device -> digital logic IC -> semiconductor. FPGAs fill the design gap between fixed-function ASICs (high NRE, low per-unit cost at volume) and small-scale glue logic (low cost, low density), offering fast time-to-market, in-field reprogrammability, and parallel hardware execution. The FLEX 6000 family occupies the low-density legacy tier of the Altera/Intel FPGA portfolio, predating the Cyclone and MAX families that replaced it for new designs. Key features of the EPF6024ATC144-11 include a dedicated carry chain architecture supporting high-speed arithmetic operations, cascade chains for wide-input logic, configurable I/O standards (TTL, CMOS), and a 4-input look-up table (LUT) per logic element. The LQFP-144 (Low-profile Quad Flat Pack, 20x20 mm, 0.5 mm pitch) surface-mount package provides a familiar plastic footprint compatible with hand-soldering and standard SMT assembly, unlike the later BGA packages that require X-ray inspection. The device is built on a 0.42 µm CMOS SRAM process and supports 5V core operation, distinguishing it from the lower-voltage 3.3V Cyclone family. Typical applications for the EPF6024ATC144-11 include legacy glue logic replacement, telecom interface bridging, industrial control state machines, and educational FPGA training platforms where the FLEX 6000 architecture is well documented. The wide 5V tolerance makes it particularly suitable for industrial bus interfacing (parallel ATA, ISA-style address decoding, glue logic between microcontrollers and peripherals) and for replacing multiple 74-series TTL packages in legacy equipment redesigns. When designing with this FPGA, allocate dedicated configuration PROM (such as the EPC1 or EPC1441) since the SRAM configuration cells are volatile and reload on every power-up. Provide a clean 5V supply with adequate decoupling (100 nF plus 10 µF bulk) near VCCINT pins, and ensure JTAG pins are routed to a stable header for in-system programming. Note that FLEX 6000 parts are now in mature lifecycle stages - verify stock and lead time before committing the design. This page synthesizes distributor pricing, FLEX 6000 family alternatives, and practical design considerations not consolidated in the original manufacturer datasheet, enabling engineers to evaluate the EPF6024ATC144-11 against current alternatives and to plan configuration, power, and PCB layout decisions.
EPF6024ATC144-13 - FLEX 6000 FPGA 24K Gates, 144-LQFP | Altera
The Altera (now Intel) EPF6024ATC144-13 is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays, delivering 24,000 typical gates and 1,960 logic elements in a 144-pin LQFP (TQFP) package. It is a programmable logic device from the classic FLEX 6000 series fabricated on a 0.42 µm CMOS process, with a maximum internal operating frequency of 142.86 MHz at 3.3 V core supply. The device integrates 196 Logic Array Blocks (LABs) and 117 user I/O pins, providing an entry-level platform for glue logic, bus interfacing, and state-machine prototyping. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs/LABs), programmable interconnect, and programmable I/O cells that engineers can customize post-manufacture to implement arbitrary digital logic functions. Within the broader power-management/PLD hierarchy, FPGAs sit at the top of the programmable logic tree: PLD -> CPLD -> FPGA -> SRAM-based FPGA. The FLEX 6000 family uses a look-up-table (LUT)-based architecture with continuous FastTrack interconnect routing, distinguishing it from older PAL/GAL devices and from the non-volatile MAX series CPLDs. Key features of the EPF6024ATC144-13 include 24,000 typical gates, 1,960 logic cells, 196 LABs, 117 maximum user I/O, in-system programmability via the serial configuration EPROM interface, 5V-tolerant I/O on a 3.3 V core, and JTAG boundary-scan support. The -13 speed grade corresponds to a pin-to-pin delay of approximately 13 ns, making the part suitable for moderately fast control logic and bus-bridge applications rather than high-speed DSP pipelines. Architecturally, the device uses a hierarchical interconnect structure with row and column FastTrack channels that route signals between LABs. Each LAB contains 10 Logic Elements (LEs), and each LE carries a 4-input LUT, a programmable register, and a carry chain for arithmetic. Embedded array blocks (EABs) provide small memory primitives for FIFO and shallow RAM functions. Typical applications include industrial control glue logic, telecommunications interface bridges, peripheral bus adapters (PCI, ISA, VME bridges), motor-control sequencers, legacy system modernization, and low-volume ASIC prototyping where the 144-pin LQFP footprint is already designed in. The wide package and modest gate count also make it a popular choice for educational FPGA platforms and laboratory teaching kits. When designing with this part, ensure the configuration EPROM (EPC1, EPC2, or compatible) is correctly sized for the bitstream and that JTAG chain integrity is verified prior to in-system programming. Because the FLEX 6000 family is built on 0.42 µm SRAM cells, the bitstream is volatile - the device must be reconfigured on every power-up unless an external controller holds the part in reset until configuration completes.

EPF6024ATC144-14 - FLEX 6000 FPGA, 24K Gates, 144-TQFP | Altera
The Altera EPF6024ATC144-14 is a member of the FLEX 6000 family of SRAM-based Field-Programmable Gate Arrays (FPGAs) housed in a 144-pin Thin Quad Flat Pack (TQFP) package. It integrates 24,000 typical gates (logic density), 1,960 logic elements (LEs) organized as 196 Logic Array Blocks (LABs), and 117 user I/O pins, making it a mid-density programmable logic solution for glue logic, bus interfacing, and state-machine-heavy designs in the late-1990s/early-2000s era. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that uses an array of configurable logic blocks (CLBs/LABs), programmable interconnects, and programmable I/O cells to implement arbitrary digital logic. FPGAs sit at the top of the programmable logic hierarchy (PLD -> CPLD -> FPGA) and offer the highest logic density and richest feature set at the cost of higher static power consumption and configuration memory requirements. The FLEX 6000 family uses a look-up-table (LUT)-based LAB architecture with SRAM configuration memory, requiring an external configuration ROM on power-up. Key features of the EPF6024ATC144-14 include: 1,960 LEs, 196 LABs, 117 user I/O pins, typical operating frequency up to 200 MHz at the -3 speed grade, and 5V-tolerant I/O on a 3.3V core supply. The -14 speed grade denotes the slowest commercial grade, targeting cost-sensitive industrial and consumer applications where clock rates below 100 MHz are acceptable. The 144-pin TQFP package is a plastic surface-mount form factor with 0.5 mm lead pitch and a 22 mm x 22 mm body, designed for standard SMT reflow assembly. The FLEX 6000 architecture uses a four-input LUT-based logic element, a hierarchical interconnect with FastTrack continuous routing, and embedded memory. The 1960-LE capacity is sufficient for medium-complexity glue logic, peripheral bridges, custom bus controllers, and instrumentation front-ends, but is now considered low-density by modern standards. Typical applications include industrial motor-control interfaces, telecommunications line cards, custom peripheral bridges in legacy embedded systems, test and measurement backplanes, and ASIC prototyping. The 117 I/O pins support wide parallel buses (16-bit or 18-bit) common in legacy parallel interfaces such as ISA, PC/104, and VME. When designing with this device, note that the FLEX 6000 family is mature and Intel/Altera recommends the MAX II or Cyclone series for new designs; the EPF6024ATC144-14 remains useful for long-lifecycle products, EOL bridge buys, and existing board repairs. Configuration requires an EPC configuration device or microcontroller-based configuration mode.

A field-programmable gate array (FPGA) is a reconfigurable integrated circuit that combines programmable logic blocks, programmable interconnect, and programmable I/O cells on a single semiconductor die. The FLEX 6000 family targets low-cost, high-volume gate-array replacement and rapid prototyping; within the broader semiconductor taxonomy it sits as a sub-class of programmable logic devices (PLDs) alongside CPLDs and structured ASICs. Key features of the EPF6024ATC144-15 include a 3.3 V core supply, in-system programmability via SRAM configuration cells, built-in carry and cascade chains for high-speed arithmetic and wide-input functions, JTAG-compliant boundary-scan test support, and multi-voltage I/O banks. The -15 speed grade denotes a specific AC-timing bin within the FLEX 6000 family, where lower numeric values indicate faster timing. Architecturally, the FLEX 6000 fabric is built from SRAM-based look-up tables (LUTs) that drive a four-input combinational function, with a dedicated register for sequential logic. The carry chain supports fast counters and adders, while cascade chains connect LEs 2 through 10 in each LAB and all LABs within the same half-row, enabling minimum-delay implementation of wide-input functions. Typical applications for the EPF6024ATC144-15 include glue-logic integration in industrial control boards, telecommunications line-card controllers, bus-interface bridging (PCI, ISA, VME bridges), prototyping of gate-array designs, and replacement of discrete TTL/CMOS logic clusters where fast design changes are needed. When designing with this device, confirm configuration mode (PS, PPS, AS, JTAG), supply decoupling (at least 0.1 µF plus bulk per rail), and unused-pin handling (drive to a defined logic level or use the Quartus/MAX+PLUS II "Enable All Pins as Inputs" option to suppress spurious toggles).

EPF6024ATC144-17 - FLEX 6000 FPGA 117 I/O 144-TQFP | Intel
The Intel (formerly Altera) EPF6024ATC144-17 is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays, offering 1960 logic elements organized into 196 logic array blocks (LABs) and 117 user I/O pins in a 144-pin TQFP package. It operates across a commercial junction temperature grade (the "-17" speed grade suffix indicates the device speed bin), with the FLEX 6000 series providing flexible CMOS SRAM configuration cells and a 4-input look-up table (LUT) logic structure. What is a FLEX 6000 FPGA? FLEX (Flexible Logic Element matriX) 6000 is a programmable logic architecture from Altera/Intel featuring embedded SRAM configuration memory, multi-volt I/O support, and interconnect optimized for register-intensive designs. Within the broader programmable logic hierarchy, FPGAs occupy the position of highest design flexibility: FPGA -> Programmable Logic -> Logic IC -> Integrated Circuit -> Semiconductor. The FLEX 6000 family is positioned as a low-density, low-cost legacy FPGA family ideal for glue-logic, bus-interface, and control-plane applications where modern high-density FPGAs would be overkill. Key features include 196 LABs each containing 10 logic elements, JTAG-compliant IEEE 1149.1 boundary-scan test support, multi-voltage I/O standards including 3.3V, 2.5V, and 1.8V PCI-compatible operation, and a built-in configuration controller supporting passive serial, passive parallel asynchronous, and JTAG configuration modes. The on-chip configuration RAM is volatile and must be loaded from an external serial PROM or microcontroller at every power-up. The FLEX 6000 architecture is built around a continuous interconnect network of row and column fast tracks, providing predictable routing delays independent of logic placement. Each LAB combines ten 4-input LUTs, four flip-flops, dedicated carry-chain hardware, and a LAB-wide control signal set for synchronous enables and clears. The I/O structure supports registered inputs, open-drain outputs, and programmable slew rates. Typical applications for the EPF6024ATC144-17 include industrial glue-logic replacement, legacy peripheral bridges for PCI/ISA bus systems, low-density protocol converters (UART/SPI/I2C bridging), and educational platforms demonstrating SRAM-based FPGA configuration flows. Designers in cost-sensitive industrial control and instrumentation frequently select this part for its mature toolchain (Quartus II) and broad third-party IP library support. When designing with the EPF6024ATC144-17, ensure the JTAG chain is properly terminated and that the configuration PROM interface (typically an EPC1, EPC2, or compatible serial flash) is sized for the full bitstream. The device requires a clean 3.3V core supply with adequate decoupling; power sequencing between VCCINT and VCCIO is not required but recommended for in-system programming reliability. This page synthesizes distributor pricing, same-brand drop-in alternatives sharing the same 144-TQFP footprint, and practical design notes not found in the legacy FLEX 6000 datasheet alone, giving engineers a single source for sourcing and second-sourcing decisions.
EPF6024ATC144-18 - FLEX 6000 FPGA 24K Gates 144-TQFP | Intel
The Intel (formerly Altera) EPF6024ATC144-18 is a member of the FLEX 6000 family of SRAM-based FPGAs, providing 24,000 typical gates, 1,960 logic elements (LEs), and 196 logic array blocks (LABs) in a 144-pin Thin Quad Flat Pack (TQFP) package with industrial-grade speed grade -18. Built on a 5V-tolerant CMOS SRAM process, the FLEX 6000 family was designed as a low-cost programmable alternative to high-volume gate-array applications, enabling rapid design changes during prototyping and pre-production. An FPGA (Field-Programmable Gate Array) is a reconfigurable integrated circuit containing an array of programmable logic blocks, interconnect, and I/O cells that the designer configures after manufacturing using a hardware description language (HDL). FPGAs sit in the broader taxonomy of programmable logic devices (PLDs) and bridge the gap between fixed-function ASICs (high NRE, high volume) and discrete logic (low density, slow prototyping). Within the Altera/Intel portfolio hierarchy, FLEX 6000 devices are positioned as low-density, cost-optimized SRAM FPGAs, below the FLEX 10K family (which added embedded array blocks) and well below modern Cyclone and Stratix families. Key features include 117 user I/O pins supporting 5V, 3.3V, and 2.5V I/O standards, a 3.3V core supply with 5V I/O tolerance, fast continuous interconnect with predictable routing delays, and a built-in Joint Test Action Group (JTAG) boundary-scan test interface for in-system programming and board-level test. The device is configured via the Altera FLEX 6000 series configuration scheme using serial or parallel configuration devices, and supports multi-device configuration chains. The FLEX 6000 architecture uses a four-input look-up table (LUT) per logic element, with carry and cascade chains for high-speed arithmetic and wide-input functions. Each LAB contains 10 LEs and connects to the FastTrack Interconnect, an efficient continuous routing fabric that minimizes timing skew and supports high-speed designs up to the device's specified speed grade. Typical applications include telecommunications interface bridging, industrial control glue logic, prototyping of ASIC designs, programmable I/O expansion for embedded microcontrollers, and educational platforms. The 144-TQFP package provides ample I/O for legacy peripheral interfacing while remaining hand-solderable for low-volume builds. Engineers commonly pair this device with EPC2 configuration PROMs for standalone operation. When designing with this device, ensure the JTAG chain order matches the Quartus MAX+PLUS II or Quartus Prime device programmer configuration. Unused I/O pins should be left floating or driven to a defined state, and the global clear (DEV_CLRn) signal must be properly terminated to avoid inadvertent resets during power-up. The -18 speed grade indicates a -18 pin/pin delay relationship used for timing-driven compilation.
EPF6024ATC144-19 - FLEX 6000 FPGA 24K Gates 144-LQFP | Intel
The Intel (formerly Altera) EPF6024ATC144-19 is a member of the FLEX 6000 family of SRAM-based field-programmable gate arrays (FPGAs), delivering approximately 24,000 typical gates (16,000 logic gates) in a 144-pin LQFP package with a -19 speed grade. The part provides 117 user I/O pins, 1,960 logic elements distributed across 196 Logic Array Blocks (LABs), and operates from a 3.3 V core supply with 5.0 V tolerant I/O compatibility per the FLEX 6000 family specification. A field-programmable gate array (FPGA) is a semiconductor integrated circuit containing an array of programmable logic blocks, interconnect resources, and configurable I/O cells that the designer can personalize after manufacture to implement any digital logic function - from simple glue logic to complex state machines, bus bridges, and DSP pipelines. Within the broader taxonomy, FPGAs belong to programmable logic devices (PLDs) -> logic ICs -> integrated circuits. The FLEX 6000 family was Altera's first-generation look-up table (LUT)-based FPGA architecture, positioned for glue-logic, bus-interface, and high-volume consumer/industrial applications where cost per gate and 5 V I/O tolerance were decisive factors. Key features of the EPF6024ATC144-19 include four embedded logic elements (LEs) per LAB, fast interconnect with carry and cascade chains for arithmetic and wide-input functions, JTAG (IEEE 1149.1) boundary-scan support, in-system programmability via the Altera ByteBlaster or BitBlaster loaders, and an -19 speed grade (commercial) that trades off maximum toggle rate (typically ~125 MHz internal) for lower cost. The 144-LQFP package is a low-profile plastic quad flat pack with gull-wing leads and a 1.4 mm height, optimized for surface-mount production lines. Typical applications for the EPF6024ATC144-19 span glue-logic replacement for discrete 74-series TTL/CMOS, custom peripheral bus bridges (PCI, ISA, VME), industrial controller I/O expansion, and legacy-system modernization where 5 V I/O tolerance eliminates level-shifters. Because the FLEX 6000 family is fabricated on a 0.35 µm SRAM process, configuration must be reloaded from external EPROM, Flash, or microcontroller on every power-up. When designing with this part, allocate the configuration memory interface pins (MSELn, nSTATUS, nCONFIG, CONF_DONE) carefully and ensure the JTAG chain does not conflict with board-level boundary-scan. Designers migrating to a newer family should evaluate the MAX II or Cyclone series as successors with substantially higher density and lower power.
EPF6024ATC144-1N - FLEX 6000 FPGA, 1960 Cells, 144-TQFP | Intel
The Intel (formerly Altera) EPF6024ATC144-1N is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs) housed in a 144-pin TQFP (Thin Quad Flat Pack) package. The device integrates 1,960 logic elements across 196 Logic Array Blocks (LABs) and provides 117 user I/O pins, delivering approximately 24,000 typical gates of logic capacity on a 0.42 µm CMOS process. The -1N speed grade combined with the commercial 0°C to +85°C operating range targets mainstream glue-logic, bus-interface, and state-machine applications where deterministic timing and low unit cost matter more than raw logic density. An FPGA (Field-Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks, programmable interconnects, and I/O cells that the user can define after manufacture via a configuration bitstream. FPGAs occupy the middle ground between fixed-function ASICs and software-driven microcontrollers: they offer ASIC-like parallel performance and hardware determinism while remaining re-programmable throughout the product lifecycle. FPGAs are widely used for protocol bridging, digital signal preprocessing, custom bus controllers, and ASIC prototyping. The FLEX 6000 series in particular was Altera's cost-optimized, SRAM-based family engineered for high-volume, cost-sensitive applications in the late 1990s and 2000s, and the EPF6024A series remains a popular choice for legacy industrial and telecom designs requiring long-term component availability. Key features of the EPF6024ATC144-1N include a 3.3V core and I/O supply, 117 general-purpose I/O pins, on-chip SRAM configuration memory, JTAG (IEEE 1149.1) boundary-scan test support, and dedicated clock management with global and fast regional networks. The TQFP-144 package (JEDEC MS-026 designation) provides a 1.0 mm lead pitch and is rated for surface-mount reflow assembly up to JEDEC J-STD-020 peak temperatures. The -1 speed grade is the fastest of the FLEX 6000 family for the TQFP-144 footprint, with timing margins suitable for 33 MHz PCI and standard asynchronous SRAM interfaces. Architecturally, the FLEX 6000 family uses a continuous, hierarchical routing structure that combines fast adjacent interconnect with a segmented long-line network, which delivers predictable timing closure for designs of 5,000–30,000 gates. Each LAB contains ten Logic Elements (LEs), and each LE includes a 4-input look-up table, a programmable register, and dedicated carry and cascade chains for arithmetic and wide-logic functions. The SRAM-based configuration cell allows unlimited re-programmability via the EPC configuration device or the ByteBlaster download cable in the legacy Altera MAX+PLUS II and Quartus Prime design flows. Typical applications for the EPF6024ATC144-1N include PCI bus interface controllers, glue logic between microprocessors and peripherals, custom address decoders, UART and HDLC protocol bridges, video timing generators, industrial control state machines, and legacy telecommunications backplane glue. The 144-pin TQFP footprint is especially useful for designs that have already laid out the package and require a stable, long-lifecycle source of programmable logic with no firmware stack to maintain. When designing with this device, ensure the 3.3V supply is well decoupled with a 0.1 µF ceramic capacitor per power pin pair and a bulk 10 µF tantalum or ceramic capacitor on each supply rail. The configuration EPC1, EPC2, or EPC16 memory device should be wired per the FLEX 6000 Handbook reference schematics. Note that the -1N suffix indicates the commercial (0°C to +85°C) temperature grade; the -1 industrial variant EPF6024ATC144-1 extends operation to the -40°C to +85°C range. This page synthesizes distributor stock, drop-in same-family alternatives, and practical design notes not found in the manufacturer datasheet, providing information gain for engineers working with legacy FLEX 6000 designs.
EPF6024ATC144-1S - FLEX 6000 FPGA 24K Gates 144-LQFP | Altera
The Intel / Altera EPF6024ATC144-1S is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays (FPGAs) delivering approximately 24,000 typical gates (logic density) in a 144-pin LQFP (Low-profile Quad Flat Pack) package. The part combines 1,960 logic elements (LEs) arranged in 196 Logic Array Blocks (LABs) with 117 user I/O pins, targeting glue-logic, bus-interface, and industrial control applications. The device is built on a 0.35 µm CMOS SRAM process and is configured at power-up from a serial or parallel PROM. What is an FPGA? A Field Programmable Gate Array is a programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs/LEs) connected via programmable interconnect and surrounded by programmable I/O cells. FPGAs sit higher than fixed-function ASICs in the design flexibility hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA. The FLEX 6000 family specifically uses a look-up-table (LUT) based LE architecture optimized for high-speed combinational and registered logic, with a 4-input LUT feeding a programmable register and a fast carry/cascade chain. Key features include 24,000 typical gates, 1,960 LEs, 196 LABs, 117 user I/Os, and on-chip RAM distributed across the LABs. The EPF6024ATC144-1S uses 5.0 V VCCINT and supports 3.3 V or 5.0 V VCCIO for mixed-voltage interfacing. Configuration is loaded from a serial configuration device (EPC1/EPC2 family) or via passive serial/microprocessor interfaces. Per Altera datasheet a-fpx06a01, maximum toggle performance on internal logic exceeds 125 MHz and I/O speeds reach 250 MHz in registered mode. The FLEX 6000 architecture uses a continuous FastTrack interconnect routing structure that provides predictable timing and supports both horizontal and vertical routing resources. Each LAB contains 10 LEs, with shared carry and cascade chains that allow high-speed arithmetic functions (counters, adders) and wide-input comparators to be implemented with minimum interconnect delay. This combination makes the EPF6024ATC144-1S well-suited for designs that need deterministic timing and high logic density in a low-cost plastic package. Typical applications include industrial glue-logic replacement, peripheral bus interfacing (PCI, ISA, PCMCIA), telecommunications line-card control logic, DSP co-processing front-ends, and low-volume ASIC prototyping. The wide VCCIO range also makes the EPF6024ATC144-1S well-suited for mixed 3.3 V/5.0 V system bridging without external level shifters. Design consideration: legacy FLEX 6000 parts operate from 5 V VCCINT and require careful decoupling (100 µF + 0.1 µF bulk + bypass). Modern low-voltage 1.8 V/2.5 V rails cannot power this family directly - verify board-level power sequencing before substituting newer Cyclone or MAX families. Engineers migrating from this part should confirm that 5.0 V VCCINT is available on the PCB or plan for a regulator.

The Intel (formerly Altera) EPF6024ATC144-2 is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs), delivering 24,000 gates, 1,960 logic cells, and 117 user I/O in a 144-pin Thin Quad Flat Pack (TQFP) package. It operates at 3.3 V core and I/O supply, supports a maximum internal operating frequency of 166.67 MHz, and is fabricated on a 0.42 µm CMOS SRAM-based process. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be re-programmed by the designer after manufacture. FPGAs sit in the programmable logic hierarchy between simple PLDs and high-density ASICs, offering parallel processing, deterministic timing, and in-system reprogrammability. The FLEX 6000 series is positioned as a low-cost, low-density family for glue logic, bus interfacing, and DSP co-processing where ASIC NRE is unjustified. Key features of the EPF6024ATC144-2 include 1,960 logic elements, 117 maximum user I/O, embedded array blocks (EABs) for memory implementation, in-system programmability via the IEEE 1149.1 (JTAG) boundary-scan interface, and 3.3 V LVTTL/LVCMOS-compatible I/O. The device supports multi-voltage I/O with 5.0 V tolerance on inputs and operates over the commercial 0 °C to +70 °C junction temperature range (as indicated by the speed-grade and temperature suffix). Architecturally, the FLEX 6000 family uses a continuous, hierarchical interconnect fabric (FastTrack) with row and column routing channels. Logic elements (LEs) are grouped into Logic Array Blocks (LABs), each containing 10 LEs. Embedded Array Blocks (EABs) provide 2 Kbits of SRAM (configurable as RAM, ROM, or FIFO) and can be cascaded to build wider/faster memory blocks without consuming general-purpose routing. Typical applications include peripheral bus interfacing (PCI, ISA, VME bridges), digital signal processing front-ends, industrial control logic, glue-logic consolidation on multi-board systems, and legacy ASIC replacements where 24K gates is sufficient. Designers often choose the FLEX 6000 family for low-cost prototyping and short-run production where Cyclone or MAX series migration is impractical. When designing with the EPF6024ATC144-2, pay attention to the JTAG chain integrity for ISP and use the Quartus II / MAX+PLUS II legacy toolchain for bitstream generation. Note that 5.0 V input tolerance depends on the specific I/O bank configuration; consult the device datasheet for absolute maximum ratings.

EPF6024ATC144-20 - FLEX 6000 FPGA 1960 LE 144-LQFP | Intel / Altera
The Intel / Altera EPF6024ATC144-20 is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays (FPGAs), offering 1960 logic elements (LEs), 196 Logic Array Blocks (LABs), and 117 user I/O pins in a 144-pin LQFP (Plastic Low-Profile Quad Flat Pack) package with 0.5 mm pitch. The "-20" speed grade corresponds to a 20 ns worst-case pin-to-pin delay across the FLEX interconnect, making it suitable for general-purpose glue-logic and bus-interface designs where moderate performance is acceptable. An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) that combines the density of a gate array with the design flexibility of in-system programmability. Within the broader taxonomy, FPGAs sit alongside CPLDs under the Programmable Logic Device umbrella, which itself belongs to the digital integrated circuit family. The FLEX 6000 series uses a fine-grained architecture of 4-input look-up tables (LUTs) packaged into LABs that interconnect via FastTrack continuous routing channels, with carry and cascade chains for high-speed arithmetic and wide fan-in functions. FPGAs of this generation are typically configured from an external serial EPROM at power-up. Key features of the EPF6024ATC144-20 include 24,000 typical gates, multiVolt I/O supporting 5.0 V, 3.3 V, and 2.5 V mixed-voltage operation, in-system programmability via the ByteBlaster or BitBlaster download cable, and JTAG boundary-scan compatibility (IEEE Std 1149.1). The device is fabricated on a 0.35 µm CMOS SRAM process and operates from a 3.3 V core supply. Pin-to-pin logic delay tPD is specified at 20 ns for this speed grade. The device supports SRAM-based configuration loaded from a serial configuration EPROM such as the EPC2, allowing rapid prototyping and field upgrades. Each LAB contains 16 LEs, and each LE contains a 4-input LUT, a programmable register, carry and cascade logic, and an output buffer. MultiVolt I/O allows the device to interface directly with 5 V TTL, 3.3 V LVTTL, and 2.5 V HSTL/LVCMOS peripherals without external level shifters. Typical applications for the EPF6024ATC144-20 include industrial control logic, glue-logic bridges between microcontrollers and peripherals, low-to-medium complexity state machines, custom bus interfaces (PCI, ISA, VME bridges), and legacy telecommunications equipment. Its moderate logic density and 117 I/Os make it ideal when several discrete TTL/CMOS parts can be replaced by a single reconfigurable device. When designing with this part, note that the LQFP-144 footprint is footprint-compatible with other FLEX 6000 devices in the same package, allowing upward migration to higher-density family members (such as the EPF6016ATC144 or EPF6024AQC240 in different pin counts) without PCB rework on compatible packages. Designers should also budget for a configuration EPROM on the board and provide a JTAG header for in-system programming.

EPF6024ATC144-23 - FLEX 6000 FPGA, 24K Gates, 117 I/O | Altera
The Altera (Intel) EPF6024ATC144-23 is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays (FPGAs) fabricated on a 0.42 um CMOS process, packaged in a 144-pin TQFP (thin quad flat pack). The device integrates 24,000 typical gates and 1,960 logic elements distributed across 196 Logic Array Blocks (LABs), with 117 user I/O pins and a maximum internal operating frequency of approximately 142.86 MHz. According to FPGAkey and Mouser distributor listings, the part operates from a 3.3 V core supply and supports 5.0 V tolerant I/O with proper pull-up configuration. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the density of a gate array with the in-system reprogrammability of a logic device. FPGAs sit at the top of the programmable logic hierarchy: PLD -> CPLD -> FPGA, and are widely used as flexible alternatives to fixed gate-array ASICs during prototyping and in low-to-medium volume production. The FLEX 6000 family specifically targets low-cost, high-volume designs where fast design changes are required without the NRE costs of mask-programmed logic. The EPF6024ATC144-23 features a continuous, hierarchical routing architecture with carry chains for high-speed arithmetic and cascade chains for wide-input functions, both of which connect Logic Elements (LEs) within and across LABs. The IC supports in-system configuration via the Altera (now Intel) MAX+PLUS II or Quartus design environment, allowing engineers to iterate quickly on glue logic, bus interfaces, and state-machine controllers. Its 117 available I/Os make it suitable for bridging multiple peripheral buses in cost-sensitive embedded designs. Typical applications include telecommunications glue logic, industrial control and instrumentation front-ends, peripheral bus bridges (e.g., UART, SPI, or I2C controllers), and prototype replacement of small ASICs. The wide 5.0 V I/O tolerance (with appropriate pull-up design) also simplifies interfacing to legacy 5.0 V peripherals in retrofit designs. Designers migrating from older discrete-logic implementations typically select the EPF6024ATC144 family to consolidate board real-estate while maintaining 5.0 V compatibility. When designing with this device, attention must be paid to the I/O bank's VCCIO supply voltage - the part supports 3.3 V CMOS outputs natively, but 5.0 V CMOS input thresholds require external pull-up resistors as detailed in the FLEX 6000 datasheet family. Configuration storage is volatile (SRAM-based), so the bitstream must be reloaded from a boot PROM on every power-up. Designers should also verify the exact speed grade (-1, -2, -3) needed for their timing budget; the -23 suffix indicates a specific speed grade and temperature range combination that should be matched against timing-closure requirements before PCB commit.
