EPF6016QC240-2N - 16K Gates FLEX 6000 FPGA, 240-PQFP | Intel
The Intel (Altera) EPF6016QC240-2N is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs), delivering 16,000 gates (1,320 logic cells/elements) and 199 user I/Os in a 240-pin Plastic Quad Flat Pack (PQFP/BQFP) package. It is built on a 0.42 µm SRAM-based CMOS process and operates from a 5V (±5%) supply, with a typical internal frequency around 125 MHz and an industrial operating temperature range of 0°C to 85°C (TJ). What is an FPGA? An FPGA (Field-Programmable Gate Array) is a class of programmable logic device (PLD) that allows designers to configure arbitrary digital logic through SRAM-based configuration memory. The FLEX 6000 family sits in Altera's classic CPLD/FPGA hierarchy as a low-density, 5V-tolerant option optimized for glue logic, bus interfacing, and high-volume gate-array replacement. Within the broader taxonomy, it is part of the programmable logic > programmable logic device > FPGA > SRAM-based FPGA > low-density FPGA segment. Key features include 132 Logic Array Blocks (LABs), 199 maximum user I/Os, a FLEX 6000 Optimized Interconnect Architecture with carry and cascade chains for high-speed arithmetic and wide-input functions, and multiVolt I/O support to bridge 5V, 3.3V, and 2.5V system buses. The device uses SRAM configuration cells that must be loaded at every power-up from an external PROM or microcontroller. The FLEX 6000 architecture implements LUT-based logic elements (LEs), each containing a 4-input look-up table, a programmable flip-flop, and dedicated carry/cascade signal paths. Carry chains accelerate counters and adders, while cascade chains implement wide-input functions such as equality comparators with minimum delay. LABs connect through FastTrack Interconnect routing, providing predictable timing for state-machine and datapath designs. Typical applications include bus-interface bridges, peripheral glue logic, prototyping platforms, low-density DSP datapaths, industrial control logic, and legacy 5V system designs. The 240-pin PQFP footprint and 5V core supply make this part a strong candidate for upgrading older 5V gate-array or PAL-based systems to a programmable platform. Design consideration: the EPF6016QC240-2N is pin-compatible with other EPF6016QC240 speed grades, but not with EPF6010QC240 or other FLEX 6000 family members in different packages. Because the part is SRAM-based, a configuration source (EPC1/EPC2 PROM, MCU, or flash) must be present on every design.

It integrates 132 Logic Array Blocks (LABs) and 199 user I/O pins, delivering flexible logic density for cost-sensitive prototyping and low-to-medium volume glue-logic applications. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs/LABs), programmable interconnects, and programmable I/O cells that engineers can customize after manufacture using a hardware description language (HDL) such as VHDL or Verilog. Within the broader hierarchy, an FPGA is a type of programmable logic device (PLD) -> logic IC -> integrated circuit. The FLEX 6000 series is positioned at the low-density end of Altera's FPGA portfolio, providing an inexpensive alternative to gate arrays and standard-cell ASICs for glue logic, bus interfacing, and state-machine implementation. Key features of the EPF6016QC240-3 include a maximum internal operating frequency of approximately 172 MHz, on-chip SRAM configuration memory, in-system programmability via the IEEE 1149.1 (JTAG) interface, and 5V-tolerant I/O. The 'QC240' suffix designates the 240-pin Power QFP package with 199 usable I/O pins, while the '-3' speed grade represents a commercial-temperature (0C to 85C) mid-tier performance bin. The part supports multiple I/O standards including LVTTL, LVCMOS, and PCI for interfacing with common logic families. Architecturally, the device uses a row-and-column interconnect structure with carry and cascade chains spanning LABs in the same row half, enabling high-speed arithmetic functions such as counters, adders, and wide-input comparators with minimal delay. Each LAB contains 10 Logic Elements (LEs), and configuration is loaded from a serial PROM or via JTAG boundary-scan. Typical applications include bus interfacing (PCI, ISA, and processor bus bridges), glue-logic replacement, peripheral controllers, and prototype ASIC emulation. It is well-suited to industrial control, telecommunications line cards, and educational platforms where low-cost, quick-turn programmability outweighs the need for high gate count or high performance. This part is widely available on the secondary market because the FLEX 6000 family has been EOL'd by Intel; the EPF6016QC240-3 is now classified as obsolete (EOL). When designing with this device, note that the FLEX 6000 family uses 5V core and I/O supply, so level shifting is required when interfacing with modern 3.3V or 1.8V logic. Designers should also provision JTAG access for in-system reconfiguration during prototype bring-up. The MaxPlus+ II or Quartus II (legacy support) toolchains provide EDIF 2.0/3.0, VHDL, Verilog HDL, and LPM entry, making it compatible with mainstream synthesis flows.

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 reconfigurability of a logic IC. Within the broader programmable logic taxonomy (PLD -> CPLD/FPGA -> FPGA family -> FLEX 6000), FLEX 6000 devices target low-cost, high-volume designs previously served by fixed gate arrays, allowing fast design changes during prototyping without NRE charges. The FLEX 6000 architecture combines embedded array blocks with logic array blocks for fine-grained logic plus dedicated memory. Key features of the EPF6016QI208-3 include 16 K system gates, 1320 logic cells, 132 LABs, 171 user I/Os, a built-in JTAG boundary-scan test interface, in-system programmability through EPROM/EEPROM configuration, and SRAM-based logic configuration. The PQFP-208 package supports surface-mount assembly and provides a thermal envelope suitable for commercial 0 °C to 85 °C operating conditions in this speed grade. The part is fabricated on a 0.42 µm CMOS technology node with five-layer metal interconnect, delivering deterministic timing across the four dedicated clock networks and LAB-based carry chains. Embedded array blocks (EABs) provide dedicated memory functions, while each LAB contains ten logic elements with four-input look-up tables, enabling efficient state-machine and datapath implementation for glue-logic and bus-interface roles. Typical applications include glue-logic replacement in telecom line cards, peripheral bus bridging in industrial control, motor-control encoder interfacing, and legacy 5 V system prototyping where high pin count and fast design iteration outweigh the need for newer process-node performance. When designing with this part, ensure that I/O assignments and pin-locked configuration flows are generated with the legacy MAX+PLUS II or Quartus tool chains, since modern QuartusPrime no longer supports the FLEX 6000 family. Provide 5 V ±5% rail decoupling with 0.1 µF and 10 µF capacitors close to each VCC pin. This page synthesizes distributor pricing snapshots, same-package drop-in alternatives from the same FLEX 6000 family, and practical design notes not collected in the original 1999-era datasheet.

The 'QI' package designator denotes the industrial temperature grade and PQFP form factor, while the '-3' speed grade and 'N' lead-free suffix indicate lead-free / RoHS-compliant termination. The 208-pin PQFP (BFQFP) is a low-profile gull-wing surface-mount package suitable for socketed or hand-soldered designs. Architecturally, the FLEX 6000 device uses a continuous-channel interconnect with shared fast-track lines between LABs and adjacent LAB-row fast lines. Each LAB contains 10 Logic Elements, each comprising a 4-input look-up table (LUT), a programmable register, and carry-chain logic for arithmetic functions. Configuration is loaded from an external EPROM or serial configuration device at power-up via the FLEX 6000's dedicated configuration interface. Typical applications include legacy bus-bridge and interface adaptation in industrial controllers, communication protocol bridging (UART/SPI/I2C consolidation), pre-ASIC prototyping, ASIC prototyping, machine-control state machines, glue-logic replacement for discrete TTL, and educational logic-design platforms. The 5 V tolerance and PQFP form factor make it especially suited to retrofit projects targeting older 5 V backplanes. When designing with this FPGA, ensure that the configuration EPROM (EPC1, EPC2, or compatible serial configuration device) is correctly sized and that JTAG chain integrity is validated. Watch for 5 V I/O-bank compatibility - the FLEX 6000 supports mixed-voltage I/O, but each bank must be powered from a single rail. Use Quartus II MAX+PLUS II legacy software for design entry, as modern Quartus Prime flows do not support the FLEX 6000 family.

EPF6016TC144-2N - FLEX 6000 16K-Gate FPGA, 1320 Cells, 144-TQFP | Intel / Altera
The Intel / Altera EPF6016TC144-2N is a member of the FLEX 6000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs), integrating 16,000 typical gates (approximately 13,000 usable gates) and 1,320 logic cells across 132 Logic Array Blocks (LABs), housed in a 144-pin Thin Quad Flat Pack (TQFP) package with 117 user I/O pins. An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor device that contains an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, allowing designers to implement arbitrary digital logic through software-defined bitstream programming. Within the broader semiconductor taxonomy, the EPF6016TC144-2N sits in the programmable logic family, between simple SPLDs/CPLDs and high-density FPGAs, targeting glue-logic and bus-interface applications. The FLEX 6000 family is built on a 0.42 µm CMOS SRAM process, requiring external configuration memory (typically an EPC2 or EPC16 configuration device) to load the bitstream at power-up. Key features of the EPF6016TC144-2N include a maximum internal toggle frequency of 125 MHz, a 5 V (4.75 V to 5.25 V) single-supply operation, 5 mA quiescent supply current, an operating temperature range of 0 °C to 85 °C (commercial grade), and True-LVDS/LVTTL/MultiVolt I/O support. The device is RoHS compliant and supports in-system programmability via the JTAG (IEEE 1149.1) boundary-scan interface, enabling rapid prototyping and field upgrades. Architecturally, each LAB contains 10 Logic Elements (LEs), each LE comprising a 4-input look-up table (LUT), a programmable register, and a carry chain for arithmetic functions. The 117 user I/Os are arranged around the package perimeter with FastTrack interconnect providing predictable routing delay. The -2N speed grade identifies a specific timing bin within the FLEX 6000 family, sitting between the -3 (slower) and -1 (fastest) grades. Typical applications include peripheral bus interfacing (PCI, ISA, VME), glue-logic integration, custom state-machine controllers, communication channelizers, and industrial control subsystems. The device is widely used in legacy telecom line-card designs and is supported by the classic Altera MAX+PLUS II and Quartus design flows for backwards compatibility. When designing with the EPF6016TC144-2N, ensure that the configuration scheme (PS, AS, or JTAG) is chosen early in the design cycle, and that the 5 V supply is well decoupled with 0.1 µF ceramic capacitors placed within 5 mm of every VCC pin. The I/O banks can be configured independently, but 5 V tolerance requires the PCI-compliant I/O standard on the relevant banks.

EPF6016TC144-3 - FLEX 6000 FPGA, 16K Gates, 144-LQFP | Altera
The Altera EPF6016TC144-3 is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays (FPGAs) housed in a 144-pin LQFP package. Built on a 0.42 µm CMOS process with 5V core operation, the device delivers approximately 16,000 typical gates, 1,320 logic elements distributed across 132 Logic Array Blocks (LABs), and 117 user I/O pins, with a maximum internal frequency of 125 MHz and a system frequency rating around 172 MHz. The "TC144" suffix denotes the TQFP commercial-temperature package, while the "-3" speed grade indicates the standard performance tier within the FLEX 6000 line. A Field Programmable Gate Array (FPGA) is a reconfigurable integrated circuit that combines programmable logic blocks, programmable interconnects, and programmable I/O cells into a single die. Unlike an ASIC, an FPGA's function is defined post-fabrication by loading a configuration bitstream into on-chip SRAM. In the system hierarchy, an FPGA sits between a microcontroller and an ASIC: it offers more flexibility than an MCU for parallel DSP or custom I/O tasks, and faster time-to-market than an ASIC for low-to-medium volume designs. The FLEX 6000 family specifically targets glue-logic, bus-interface, and low-density control-plane applications where 5V tolerance and QFP packages are still valued. Key features of the EPF6016TC144-3 include continuous SRAM-based reconfigurability, multi-volt I/O support (3.3V and 5V tolerant interfaces), JTAG-based boundary-scan testing compliant with IEEE 1149.1, and four low-skew global clock networks. The device is supported by the Altera MAX+PLUS II and Quartus design flows, with EDIF 2.0/3.0 netlist, VHDL, Verilog HDL, and LPM (Library of Parameterized Modules) interfaces for third-party EDA tools from Cadence, Mentor Graphics, Synopsys, and OrCAD. Architecturally, the FLEX 6000 LAB is built from 10 Logic Elements (LEs), each containing a 4-input look-up table, a programmable register, and a dedicated carry chain for fast arithmetic. The interconnect uses a continuous FastTrack routing matrix that delivers predictable timing across the die. The 5V-tolerant I/Os can interface directly to legacy TTL/CMOS peripherals without external level shifters, which is the key reason FLEX 6000 parts remain specified in industrial backplane and instrumentation designs. Typical applications include industrial glue logic, legacy 5V bus bridges, motor control pre-processing, telecommunications backplane controllers, prototyping platforms for ASIC emulation, and test & measurement front-end logic. Designers usually pair the EPF6016TC144-3 with an EPC2 configuration device to store the SRAM bitstream at power-up. When designing with this part, note that configuration data is volatile: the FPGA must be reconfigured at every power-up, so a serial configuration PROM or microcontroller must be included in the BOM. The commercial-grade temperature range (0°C to 85°C) must also be respected; for harsher environments, an industrial-grade variant (suffix "I") should be specified instead. This page consolidates distributor pricing, drop-in same-family alternatives from the FLEX 6000 line, and practical design notes that are not repeated in the manufacturer datasheet itself, helping engineers compare and select between the many -1, -2, and -3 speed grades that Altera shipped in this family.
EPF6016TC144-3N - FLEX 6000 FPGA 16K Gates 117 IOs | Intel
The Intel EPF6016TC144-3N is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays (FPGAs), housed in a 144-pin TQFP (TQ144) surface-mount package and providing approximately 16,000 usable gates with 117 user I/Os. It contains 132 Logic Array Blocks (LABs), an internal frequency of 172 MHz, and operates over the commercial 0°C to 85°C temperature range. The "3N" speed grade and "TC144" package designators indicate a -3 speed bin in a TQFP-144 commercial-temperature grade. A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs) connected by programmable interconnect, allowing hardware designers to implement arbitrary digital logic that can be re-programmed in the field. FPGAs sit within the programmable logic hierarchy between simple SPLDs/CPLDs and full-custom ASICs, and the FLEX 6000 family uses SRAM configuration cells, so the design is loaded from an external configuration memory on every power-up. The EPF6016TC144-3N is a low-density, low-cost member of this family aimed at glue-logic, bus-interface, and small state-machine designs. Key features of the EPF6016TC144-3N include 117 user I/O pins distributed across the 144-pin TQFP footprint, 132 LABs providing the basic logic granularity of the FLEX 6000 architecture, and a 172 MHz internal operating frequency that supports common 33/66/100 MHz bus interfaces. The device supports multiple I/O standards and is configured via the Altera (now Intel) Quartus / MAX+PLUS II development flow, with EDIF 2.0/3.0, VHDL, Verilog HDL, and AHDL interfaces accepted at design entry. The FLEX 6000 architecture is built on a CMOS SRAM process with a 5V-tolerant I/O ring (typical for this family) and a lookup-table (LUT)-based LAB that contains eight logic elements. Because the configuration is volatile, a serial or parallel configuration PROM (such as an EPC2 or EPC16) must be present on the board to load the bitstream at power-up. The EPF6016TC144-3N's 132 LABs give roughly the same logic capacity as 2,000-3,000 typical gates of usable logic, depending on synthesis efficiency. Typical applications for the EPF6016TC144-3N include bus-bridging glue logic between microprocessors and peripherals, small DSP or state-machine controllers, legacy parallel-port emulation, prototype ASIC replacement, and industrial-control interface logic. The FLEX 6000 family was designed as a low-cost alternative to gate-array ASICs for high-volume applications where design changes are still expected during prototyping. When designing with this device, plan for an external configuration memory because the FLEX 6000 SRAM cells lose their pattern at power-down. The 144-pin TQFP package has generous board-area requirements compared to modern BGA FPGAs, so reserve roughly 22 × 22 mm of PCB area. Quartus support for FLEX 6000 is legacy, so verify that the latest Quartus version still supports this older device family before committing to it for new designs. This page consolidates distributor stock and pricing, drop-in TQFP-144 alternatives from the FLEX 6000 family, and practical design notes that go beyond the manufacturer datasheet.

The Altera (Intel) EPF6016TC144-3U is a member of the FLEX 6000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs), integrating 16,000 typical gates (24,000 maximum), 1,320 logic cells (LEs), and 117 user I/Os in a 144-pin TQFP (TC144) package with industrial-grade timing. It is built on a 0.42 µm CMOS SRAM process and offers 4 ns pin-to-pin logic delays in the speed grade -3 variant. An FPGA (Field Programmable Gate Array) is a programmable logic device that allows designers to implement custom digital logic circuits after manufacturing. The FLEX 6000 architecture belongs to the broader taxonomy of programmable logic devices (PLDs), which also includes CPLDs (Complex Programmable Logic Devices) and SPLDs (Simple Programmable Logic Devices). FPGAs are distinguished from CPLDs by their SRAM-based configuration memory, finer-grained logic elements, and higher gate count, making them suitable for glue logic, bus interfacing, and moderate-complexity state machines. The device contains 1,320 Logic Elements (LEs) organized into Logic Array Blocks (LABs), 16 embedded Logic Array Blocks, and embedded memory structures that enable efficient implementation of FIFOs, shift registers, and small state machines. Configuration is loaded from an industry-standard EPC1/EPC2 configuration PROM or via JTAG (IEEE 1149.1 Boundary-Scan). Each I/O pin supports 3.3 V LVTTL and 5.0 V PCI interfaces, with slew-rate control and tri-state buffering. Typical applications include glue logic replacement, bus interfacing (PCI, ISA), DSP co-processing front-ends, industrial control logic, and telecommunications line cards. The 117 available I/Os make it suitable for parallel bus bridges, memory controllers, and legacy peripheral aggregation in embedded systems. The TQFP-144 package is a fine-pitch surface-mount format (0.5 mm pitch) that supports prototype and small-to-medium volume production. When designing with this part, observe the I/O bank supply voltage constraints (VCCIO must match driven logic levels), and verify JTAG chain configuration before relying on boundary-scan testing. Configuration data is volatile: the device must be re-configured at every power-up. Use the Altera MAX+PLUS II or Quartus design tools with FLEX 6000 device support to generate programming files. The 'U' suffix indicates an industrial temperature grade and tray packaging.

The '-3' speed grade targets moderate-performance logic applications where cost-effective SRAM-based programmability is required. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the designer can reprogram after manufacture to implement arbitrary digital logic. Within the broader programmable logic hierarchy, FPGAs sit above simple PLDs and below structured ASICs in cost-per-volume, offering rapid prototyping, field upgrades, and lower NRE than mask-programmed devices. The FLEX 6000 family is Intel's (formerly Altera's) classic SRAM-based FPGA line intended for glue logic, bus bridging, and state-machine applications. Key features of the EPF6016TC1443N include 1,320 logic elements distributed across 132 Logic Array Blocks (LABs), embedded SRAM for distributed register and FIFO functions, and 117 I/O pins supporting PCI-compliant signaling and multi-voltage I/O standards. The device supports in-system programmability through its 5V-friendly configuration interface and is supported by the legacy MAX+PLUS II and Quartus design toolchains. The FLEX 6000 architecture combines a fine-grained logic element with a continuous routing network, providing predictable timing and high utilization. The 0.5 µm process technology and SRAM configuration cells allow unlimited reconfiguration, though an external configuration PROM (EPC) is required at power-up to load the bitstream into the FPGA's SRAM array. Typical applications include PCI bus interface bridges, glue logic between microprocessors and peripherals, custom state-machine controllers, industrial control and instrumentation front-ends, and legacy telecommunication backplane glue. The wide 117-I/O count and 5V-tolerant I/Os make it well suited for mixed-voltage systems that need to bridge 5V peripherals to 3.3V cores. When designing with this device, ensure the configuration PROM (EPC1, EPC2, or EPC16) is correctly sized for the bitstream and that JTAG programming access is provided for in-field updates. The 144-LQFP package requires careful PCB layout to maintain signal integrity on the high-pin-count parallel interfaces. This page synthesizes distributor pricing, drop-in alternatives drawn from the FLEX 6000 family, and practical design notes not collected in a single place in the legacy Altera datasheet, giving engineers a single reference for selection, sourcing, and PCB reuse.
EPF6016TI144-2 - 16K FLEX 6000 FPGA, 117 I/O, 144-LQFP | Altera
The Altera EPF6016TI144-2 is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs) delivering 16,000 typical gates, 1,320 logic elements, and 117 user I/Os in a 144-pin LQFP (TQFP) package. Built on a 0.42 micron SRAM-based process, this loadable PLD integrates 132 Logic Array Blocks (LABs) operating from a 5V supply, with an internal frequency rated up to 172 MHz. Per the manufacturer datasheet, the device targets high-volume gate-array replacement designs where fast design changes are required during prototyping or production ramp. An FPGA (Field-Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (CLBs), routing interconnects, and I/O cells that the designer configures via a hardware description language and a vendor-supplied bitstream. FPGAs sit above CPLDs (Complex Programmable Logic Devices) in the programmable logic hierarchy because they offer higher logic density, distributed RAM, and dedicated routing - and below ASICs because they are reprogrammable rather than mask-programmed. The FLEX 6000 family, launched by Altera in the late 1990s, occupies the low-density end of the FLEX hierarchy between the MAX 7000 CPLD family and the FLEX 10K family. Key features of the EPF6016TI144-2 include in-system programmability through the IEEE 1149.1 (JTAG) interface, an SRAM-based configuration cell that supports unlimited reconfiguration cycles, multiVolt I/O supporting 5V/3.3V/2.5V interfacing, and per-pin tri-state control. The device is supported by the Quartus design tool chain (legacy Max+Plus II for original bitstream generation). It is designed for 5V core operation, which differentiates it from the lower-voltage FLEX 10K family. Architecturally, the FLEX 6000 device consists of Logic Array Blocks arranged in rows and columns, each LAB containing 10 Logic Elements (LEs) with a four-input look-up table (LUT) and a dedicated register. The embedded FastTrack continuous routing structure provides predictable timing with horizontal and vertical routing segments connecting every LAB, and the I/O elements (IOEs) are placed at the periphery of the die for 117 user I/Os at this package option. Typical applications include glue logic replacement in telecom infrastructure, industrial control and factory automation interfaces, low-density bus interface bridges, and legacy system retrofits where 5V-tolerant I/O is required. Designers transitioning from older discrete TTL/CMOS gate arrays often choose this part because the LQFP-144 footprint enables hand-reworkable prototyping on standard 0.5mm-pitch PCB technology. When designing with this part, ensure your configuration bitstream storage and JTAG chain comply with the FLEX 6000 configuration handbook. The 5V core voltage means decoupling requirements differ from modern sub-3V FPGAs; a minimum 100uF bulk plus 0.1uF high-frequency decoupling per power pin is recommended per the application notes. This page synthesizes distributor pricing, drop-in FLEX 6000 same-package variants, and design notes not assembled on the original Altera datasheet - useful for engineers managing legacy designs or sourcing drop-in replacements for EOL inventory.

Built on a 0.42 µm CMOS SRAM process, this device operates from a 5 V VCCINT core supply with VCCIO banks supporting 3.3 V or 5 V I/O standards for mixed-voltage system integration. An FPGA (Field Programmable Gate Array) is a semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be reconfigured by the end user after manufacture. FPGAs sit hierarchically under programmable logic devices (PLDs) within the broader digital IC family and are used to implement custom digital circuits without the cost or lead time of an ASIC. The FLEX 6000 series specifically targets low-cost, high-volume glue logic and gate-array replacement applications with SRAM-based configuration. Key features of the EPF6016TI144-3 include 16,000 typical gates, 1,320 logic elements, fast continuous interconnect, JTAG-based in-system programmability via the ByteBlaster or BitBlaster port, and a JTAG boundary-scan test interface compliant with IEEE Std 1149.1. The -3 speed grade designation places this part in the faster commercial tier of the FLEX 6000 family. With 117 user I/Os and a 144-pin TQFP footprint, the device provides ample connectivity for medium-complexity control, bridging, and bus-interface designs. The EPF6016TI144-3 uses a 4-input look-up table (LUT)-based logic element, fast row and column interconnect channels, and embedded memory cells distributed throughout the array. The SRAM configuration memory allows unlimited re-programmability in-system, and the FLEX 6000 architecture supports hot-socketing for field upgrades. The Quartus II and legacy MAX+PLUS II design software provide VHDL, Verilog HDL, and EDIF 2 0 0 / 3 0 0 interfaces with full timing simulation and synthesis flows. Typical applications include telecommunications line-card glue logic, industrial control and instrumentation, peripheral bus interfacing (PCI bridge, microcontroller expansion), and prototyping for gate-array or ASIC designs. The 5 V core and 3.3 V tolerant I/O make it well suited for legacy 5 V systems and 3.3 V mixed-voltage designs. When designing with this device, pay close attention to the VCCINT/VCCIO separation: VCCIO must be at least 4.75 V for tOD1 timing, otherwise tOD2 (nominally slower) applies. Decoupling must follow the reference design's capacitor count and placement to maintain signal integrity on the 117 I/O pins.

EPF6016TI144-3N - FLEX 6000 FPGA, 16K Gates, 144-LQFP | Intel / Altera
The Intel (formerly Altera) EPF6016TI144-3N is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs), delivering approximately 16,000 logic gates (1,320 logic elements / 132 LABs) at a 0.42 µm CMOS process node, packaged in a 144-pin LQFP (TQFP) with gull-wing leads. The device supports up to 117 user I/O pins and operates on a 5.0 V core supply with selectable VCCIO rails of 3.3 V or 5.0 V for flexible mixed-voltage interfacing. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs / LEs), programmable interconnect, and programmable I/O cells. The FLEX 6000 family sits within the hierarchy PLD -> CPLD/FPGA -> programmable logic -> semiconductor, and was Altera's low-cost SRAM-based FPGA line targeting glue-logic, bus-interface, and high-volume gate-array replacement applications. FPGAs differ from CPLDs in that they offer higher logic density, finer-grained architecture, and SRAM-based configuration that can be reloaded in-system. Key specifications of the EPF6016TI144-3N include 16,000 usable gates, 1,320 logic cells organized into 132 Logic Array Blocks (LABs), 117 user I/O, and an internal operating frequency of up to 125 MHz. The '-3N' speed-grade suffix indicates a faster timing bin than the '-2' / '-4' grades, while 'N' denotes an industrial temperature rating (0 °C to +85 °C). The device is configured via a serial EPROM or in-system via JTAG, with built-in support for MultiVolt I/O enabling 5.0 V tolerance on a 3.3 V VCCIO rail. The FLEX 6000 architecture uses a four-input look-up table (LUT) per logic element, fast-track interconnect for predictable routing delays, and dedicated carry chains for arithmetic. Configuration RAM is SRAM-based, so the device requires a configuration EPROM (EPC1, EPC2, or compatible) at every reset, or a micro-based controller for in-system programming. Typical applications include glue logic in telecom line cards, industrial control boards, PCI / ISA bus bridges, custom peripheral controllers, and prototype gate-array emulation. The wide VCCIO range also makes the part suitable for mixed 3.3 V / 5.0 V legacy systems that require voltage translation on the same board. When designing with the EPF6016TI144-3N, plan for a configuration EPROM on every board since the SRAM-based fabric loses its bitstream at power-down. Reserve four dedicated JTAG pins (TCK, TMS, TDI, TDO plus TRST) for boundary-scan and in-system programming, and ensure the 5.0 V core supply is well decoupled near the device. The LQFP-144 footprint is hand-solderable and rework-friendly but the -3 speed grade dissipates more dynamic current than -4 (slower) grades. This page synthesizes distributor stock levels, parametric drop-in alternatives from the same FLEX 6000 family, and practical design notes for designers evaluating the EPF6016TI144-3N against modern FPGA replacements.

It features 117 user I/O pins, an operating voltage of 5.0 V, and speed grade 2 timing, providing a balance of logic density and I/O bandwidth for cost-sensitive embedded designs. An FPGA (Field Programmable Gate Array) is a reconfigurable integrated circuit containing an array of configurable logic blocks (CLBs), programmable routing channels, and I/O cells, all of which can be redefined after manufacturing. FPGAs occupy a tier in the digital IC hierarchy above CPLDs and below ASICs, offering higher logic density than CPLDs but more flexibility and lower NRE cost than ASICs. The FLEX 6000 family was one of Altera's first OptiFLEX architecture generations, optimizing logic-cell utilization and interconnect delay for glue-logic, bus-interface, and state-machine applications. Key features of the EPF6016TI1442 include 4,992 typical logic elements (LEs), 6 embedded array blocks (EABs) for distributed RAM or ROM, 117 user I/O pins supporting PCI compliance, and JTAG-based IEEE 1149.1 boundary-scan testing. The device operates on a 5.0 V core supply with 3.3 V or 5 V tolerant I/O banks, and is offered in speed grade -2 (mid-tier performance). Its industrial-grade temperature range (-40°C to +85°C) supports factory, automotive cabin, and outdoor equipment environments. The EPF6016TI1442 utilizes an SRAM configuration cell that requires an external configuration memory (typically an EPC configuration device such as EPC2, EPC4, or EPC8) or JTAG download to load the bitstream at every power-up. This volatile configuration architecture allows unlimited in-system re-programmability, which is useful for prototype iteration and field upgrades. Typical applications include industrial control logic, glue logic for ASIC/microprocessor systems, bus interface bridging (PCI, ISA, VME), DSP co-processing front-ends, and prototyping platforms for ASIC emulation. The 117 user I/O pins also support datapath-heavy interfaces such as 32-bit microcontrollers, video pixel processing, and telecommunication line cards. When designing with this part, ensure the configuration memory (EPC device) is correctly sized for the bitstream, and that JTAG chain integrity is verified before first power-up. Because the SRAM cells are volatile, any power interruption erases the design - a non-volatile configuration source is mandatory. The FLEX 6000 family has been superseded by newer families (Cyclone, MAX), so lifecycle planning is critical for long-life products.

The -3 speed grade designates the faster of three commercial grades offered in the FLEX 6000 family, making this part suited to glue logic, control plane, and low-density signal processing applications where ASIC-equivalent performance is not required. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the density of gate arrays with the design flexibility of in-system programmability. Within the broader semiconductor taxonomy, FPGAs sit alongside CPLDs (Complex Programmable Logic Devices), SPLDs (Simple PLDs), and ASICs as configurable digital logic. FPGAs are typically used when design iteration speed, low NRE cost, or post-deployment field updates outweigh the per-unit cost advantage of a masked ASIC. The FLEX 6000 family from Altera (now Intel PSG) was an early SRAM-lookup-table-based family that bridged the gap between low-density CPLDs and high-density FLEX 10K devices. Key features of the EPF6024AFC256-3 include 1960 logic elements arranged in Logic Array Blocks (LABs), 218 maximum user I/O pins, on-chip SRAM for lookup-table-based logic implementation, an internal frequency spec of 172 MHz, a 0.42 umm process node, and 3.3 V core/IO supply. The 256-ball FineLine BGA (FBGA) package supports high I/O count with controlled-impedance signal paths suitable for backplane and multi-board designs. The FLEX 6000 family is configured via the Altera MAX+PLUS II / Quartus development flow over a serial or parallel configuration interface. Typical applications include industrial control glue logic, low-density bus bridges, peripheral expansion interfaces for embedded processors, prototyping platforms for ASIC migration, and legacy system refresh designs where the original CPLD/ASIC has been discontinued. The 3.3 V supply voltage is directly compatible with 3.3 V PCI, 3.3 V microprocessors, and LVCMOS I/O standards of its era. The 218 user I/O count supports bus-oriented designs such as 16-bit data buses plus address, control, and clock signals. When designing with this device, ensure your Quartus/MAX+PLUS II toolchain version still supports the FLEX 6000 family; newer Quartus releases have removed legacy device support. The -3 speed grade delivers the highest fMAX of the family and should be selected when timing closure is more important than power. Supply decoupling requires multiple bulk and high-frequency ceramic capacitors near each supply ball due to the simultaneous-switching-output (SSO) behavior of high-pin-count BGA packages.
EPF6024AFI256-2 - 24K Gates FLEX 6000 FPGA, 256-BGA | Intel
The Intel EPF6024AFI256-2 is a member of the FLEX 6000 family of SRAM-based field programmable gate arrays (FPGAs) delivering 24,000 typical gates, 1,960 logic elements, and 196 I/Os in a 256-ball fine-pitch BGA (FBGA) package. Operating at 5.0V core with 0.42 µm CMOS process technology, the device supports system clock rates up to 166.67 MHz and provides a register-rich, look-up-table (LUT) based OptiFLEX architecture optimized for low-cost, high-volume gate array replacement and rapid prototyping with fast design changes. A field programmable gate array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs) interconnected by a programmable routing matrix; FPGAs are widely used to implement custom digital logic, glue logic, and prototyping for ASIC designs. The FLEX 6000 family sits at the low-cost, register-rich end of the Altera/Intel FPGA portfolio, well suited to applications where high gate count and low unit cost are both required. Within the broader taxonomy, the EPF6024AFI256-2 belongs to: FLEX 6000 family -> Altera/Intel FPGA -> programmable logic device (PLD) -> integrated circuit -> semiconductor. Key specifications include 24,000 typical gates, 1,960 logic elements (LEs), 196 user I/Os, 5.0V nominal core supply, and pin compatibility across the FLEX 6000 family package options. The 'I' suffix in the package code indicates an industrial temperature grade, supporting -40°C to +85°C ambient operation. The device is supported by the Altera Quartus design toolchain (legacy MAX+PLUS II is also compatible for older designs), enabling schematic, VHDL, and Verilog entry. MultiVolt I/O compatibility allows interfacing with 3.3V and 5.0V peripherals on the same die. The OptiFLEX architecture combines a continuous routing matrix with fine-grained logic cells, providing high utilization and predictable timing closure for control-logic and datapath designs. Embedded memory and dedicated clock networks are not available in the FLEX 6000 family; designers needing these features migrate to FLEX 10K or Cyclone families. The 256-pin FBGA package supports board-level manufacturing with standard surface-mount processes and reflow soldering. Typical applications for the EPF6024AFI256-2 include industrial control logic, communication protocol bridging, glue logic between microcontrollers and peripherals, custom state machines for instrumentation, and legacy design maintenance in telecom and test equipment. Designers commonly pair it with EPROM-based configuration memory to store the SRAM configuration bitstream. When designing with this device, ensure that the configuration memory and clock distribution support the target frequency and that the I/O bank voltages match the connected peripherals. For modern designs, engineers should evaluate migration to FLEX 10K, MAX II, or Cyclone families for higher density and lower power. The device is mature and may be sourced primarily through authorized distributors and franchised brokers as new production is limited.

EPF6024AQC-280 - FLEX 6000 FPGA, 24K Gates, QFP-280 | Altera
The Altera (now Intel) EPF6024AQC-280 is a member of the FLEX 6000 family of programmable logic devices, delivering approximately 24,000 typical gates in a 280-pin QFP package. The 'AQC' suffix denotes an enhanced -A speed grade with the -280 designating the QFP-280 pin count, and the device is fabricated on a 5 V SRAM-based CMOS process with in-system programmability via the Altera MAX+plus II / Quartus flow. A programmable logic device (PLD) such as the FLEX 6000 FPGA is a digital integrated circuit whose logic function is defined by user-supplied configuration data rather than hard-wired masks. It sits in the broader taxonomy of digital ICs: PLD -> programmable logic -> FPGA (Field-Programmable Gate Array) -> semiconductor device. FPGAs occupy the highest flexibility tier of this hierarchy, allowing hardware-level parallelism with reconfiguration that microcontrollers and DSPs cannot match for true hardware-acceleration tasks. The EPF6024AQC-280 integrates up to 1,960 logic elements (LEs), 24,960 RAM bits of embedded memory, and dedicated I/O elements distributed across user I/O banks supporting multiple I/O standards including 5 V, 3.3 V, and 2.5 V. Its architecture uses Look-Up Table (LUT)-based logic with fast continuous-routing interconnects, and supports JTAG-based IEEE 1149.1 boundary-scan test. The device includes built-in circuitry for global clock networks, phase-locked loops (in the -A speed grade family), and hot-socketing support. Typical applications for the EPF6024AQC-280 span glue-logic consolidation in telecom line cards, industrial control and factory-automation backplanes, and PCI-bus interface bridging where the device replaces dozens of discrete 74-series logic chips. The high 280-pin count and ample I/O count also suit it for prototyping ASIC front-ends and for educational/legacy designs that predate the migration to Cyclone-series devices. When designing with the EPF6024AQC-280, engineers should note that the FLEX 6000 family predates Cyclone, MAX II and MAX V parts; new designs should evaluate Cyclone II/III or MAX V/VII for lower power and modern packaging, while reserving FLEX 6000 for legacy system maintenance and form-fit replacements. Decoupling, multi-voltage I/O bank planning, and JTAG chain design remain the critical PCB-level concerns.
