The device operates from a 3.3 V supply (3.0 V to 3.6 V), is built on a 0.42 µm CMOS process, and supports an internal frequency of up to 166.67 MHz, making it suitable for high-volume glue-logic and gate-array replacement designs. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the high integration of a gate array with the design flexibility of in-system programmability. In the broader system hierarchy, the FLEX 6000 family sits between simple SPLDs/CPLDs and high-density SRAM-based FPGAs such as the FLEX 10K and APEX families, targeting cost-sensitive applications that previously required fixed gate arrays. The FLEX 6000 architecture uses Look-Up Tables (LUTs), embedded array blocks (EABs), and FastTrack interconnect to deliver deterministic timing at low cost. Key features of the EPF6016ATI100-2 include 132 LABs (Logic Array Blocks), an industrial operating temperature range of 0°C to 85°C (commercial) per the distributor datasheet, and FineLine BGA-compatible pin assignments in the 100-TQFP variant. The "I" suffix indicates the industrial temperature grade, while the "-2" speed grade designates a mid-range performance bin. The device is configured via a serial EPROM or microcontroller and supports in-system programmability through the JTAG IEEE 1149.1 boundary-scan interface. Typical applications include peripheral interface bridging, custom bus controllers, glue logic in telecom and networking equipment, low-volume ASIC replacement, and rapid prototyping of digital systems. The EPF6016ATI100-2 provides an ideal low-cost, programmable alternative to high-volume gate array designs, allowing fast design changes during prototyping or production testing. When designing with this FPGA, plan for external configuration memory (typically an EPC2 or EPC16 serial configuration device) and ensure all I/O banks are powered within the 3.0 V to 3.6 V range. This page synthesizes distributor inventory data, cross-references, and engineering trade-offs that the manufacturer datasheet alone does not provide.

EPF6016ATI100-2N - FLEX 6000 FPGA, 16K Gates, 100-TQFP | Altera/Intel

The Intel/Altera EPF6016ATI100-2N is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays (FPGAs), delivering approximately 16,000 usable gates in a 100-pin TQFP (Thin Quad Flat Pack) package. The device is built on a 0.42 um CMOS SRAM process and contains 1,320 logic elements (LEs) organized into 132 Logic Array Blocks (LABs), with 81 user I/O pins and an internal maximum operating frequency of approximately 166.67 MHz at a 3.3 V core supply. It supports in-system configuration via a JTAG-compatible boundary-scan interface and provides setup times as low as 2 ns with 0 ns hold time for high-speed sequential logic. An FPGA (Field Programmable Gate Array) is a type of integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be reconfigured by the designer after manufacturing. FPGAs sit between fixed-function ASICs and software-programmable processors in the design hierarchy, offering hardware-level parallelism without the NRE cost of an ASIC. The FLEX 6000 family specifically targets low-cost, high-volume glue logic, control, and bus-interface applications where fast design changes during development are required. Key features of the EPF6016ATI100-2N include 81 user I/Os, JTAG BST (Boundary-Scan Test) support, slew-rate control on output buffers, tri-state buffer capability per I/O, and dedicated clock networks. The LABs each contain 10 LEs, and the FastTrack interconnect provides predictable timing paths between LABs. I/O pins can drive LE registers directly via the row and column interconnect, simplifying timing closure for high-speed state machines and FIFO controllers. Architecturally, the device combines a fine-grained LE structure with row/column interconnect routing, allowing automatic place-and-route via the MAX+PLUS II or Quartus design tools. The 0.42 um SRAM process supports 5.0 V tolerant I/Os when the device is powered at 3.3 V, useful for mixed-voltage bus bridging between legacy 5 V peripherals and 3.3 V processors. Typical applications include bus bridging between microprocessors and peripherals, custom peripheral glue logic in embedded systems, ASIC prototyping, state-machine controllers, and pre-production design validation. The wide I/O count supports 8/16/32-bit data buses with handshake signals. When designing, ensure the configuration EPROM (such as an EPC2 or EPC8) is correctly sized for the bitstream, and observe 3.3 V supply decoupling with at least 0.1 uF ceramic capacitors near each VCC pin to maintain signal integrity on the JTAG and high-speed I/O lines. This page combines distributor pricing, verified drop-in alternatives, and practical design notes that supplement the manufacturer datasheet for sourcing and redesign decisions.

EPF6016ATI144-2 - FLEX 6000 FPGA 16K Gates | Altera

The Altera EPF6016ATI144-2 is a member of the FLEX 6000 family of SRAM-based programmable logic devices, providing 16K typical gates (1,320 logic elements/registers), 117 user I/O pins, and a maximum internal clock frequency of 153 MHz in a 144-pin TQFP package. It is fabricated on a 0.42 µm CMOS process and operates from a single 3.3 V supply (3.0 V to 3.6 V) with 5.0 V tolerant I/O. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines an array of configurable logic blocks (CLBs), programmable routing, and I/O cells on a single die. Within the broader semiconductor hierarchy, an FPGA belongs to the digital logic IC family, alongside ASICs, CPLDs, and microcontrollers, and is favored for medium-volume glue-logic, prototyping, and pre-ASIC validation. The FLEX 6000 family specifically targets low-cost, register-rich, LUT-based designs as an alternative to gate arrays. Key features include OptiFLEX architecture with embedded memory blocks, four dedicated clock inputs and a global clock network, JTAG (IEEE Std 1149.1) boundary-scan support, in-system programmability via the serial configuration EPROM interface, and per-pin 5.0 V tolerance with PCI-clamp diodes. The -2 speed grade is the mid-tier offering of the family, sitting between the -1 (slowest) and -3 (fastest) grades. The EPF6016ATI144-2 is built on a 0.42 µm SRAM cell, providing volatile configuration that must be loaded at every power-up from an external EPROM or microcontroller. The -A speed/power descriptor denotes the industrial temperature grade (-40 °C to 100 °C) in the TQFP-144 footprint, and the I indicates an industrial temperature range variant. Typical applications include industrial control glue logic, PCI interface bridges, telecommunications line cards, and prototyping for ASIC designs. The high I/O count (117) makes it well-suited for bus-intensive designs such as 32-bit microprocessor interfaces. It is also widely used in legacy telecom backplane designs where long-term availability and pin compatibility with the FLEX 6000 family are required. When designing with this device, ensure that a configuration EPROM (such as EPC2 or EPC8) is used because the SRAM cells are volatile, and verify that the Quartus II / MAX+PLUS II toolchain (legacy support) supports the targeted -2 speed grade. Designers migrating from -2 to -3 grades must re-time their designs, as internal delays scale with the speed grade.

EPF6016ATI144-3 - FLEX 6000 FPGA, 132 LABs, 117 I/O, 144-LQFP | Intel

The Intel EPF6016ATI144-3 is a member of the FLEX 6000 family of Field Programmable Gate Arrays, featuring 1320 logic elements (LEs), 132 Logic Array Blocks (LABs), and 117 user I/O pins, housed in a 144-pin LQFP package. The device operates at up to 142.86 MHz and is built on a 3.3V CMOS process optimized for low-cost, high-volume designs. The "TI" suffix denotes an industrial temperature range (TJ from -40C to +100C), and the "-3" speed grade indicates a standard performance tier within the family. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows designers to implement custom digital logic through configuration rather than fixed silicon. The FLEX 6000 family sits within Intel's PLD hierarchy: PLD -> SRAM-based FPGA -> FLEX 6000 series -> EPF6016 sub-family. FPGAs enable rapid prototyping, hardware-level parallelism, and post-manufacture design changes that ASICs cannot offer, making them ideal for glue logic, interface bridging, and small-to-medium digital systems. Key features of the EPF6016ATI144-3 include 16,000 typical gates, a 4-input Look-Up Table (LUT) architecture, SRAM-based configuration memory, multiVolt I/O support for interfacing with 5.0V, 3.3V, and 2.5V devices, and JTAG-compliant boundary-scan testing (IEEE Std. 1149.1). The device also offers in-system programmability (ISP) via the JTAG port or the dedicated configuration interface, allowing field upgrades without removing the part from the board. Architecturally, the FLEX 6000 series uses an SRAM-based 4-input LUT fabric with embedded memory and routing interconnect, providing a balance of logic density and predictable timing. The 144-LQFP package offers 117 usable I/O pins after accounting for power, ground, configuration, and JTAG pins. The "I" in the part number indicates the industrial operating range, and the speed grade "-3" places this part in the standard-performance tier. Typical applications include telecommunications interface cards, industrial control and glue logic, legacy digital system prototyping, glue logic between microcontrollers and peripherals, parallel bus interfaces, and state-machine controllers. The 117 user I/O count and 142.86 MHz Fmax support moderate-complexity designs that require parallel processing or multiple parallel interfaces. When designing with this device, note that configuration data must be loaded from an external serial or parallel PROM at power-up because FLEX 6000 devices are SRAM-based and lose configuration when power is removed. Power sequencing, decoupling, and JTAG chain integrity are critical design considerations. This part is marked as obsolete on distributor channels - design for longevity by sourcing authorized stock or planning a migration to the MAX II or Cyclone equivalent families.

EPF6016ATI144-3N - FLEX 6000 FPGA 16K Gates 117 I/O | Altera / Intel

The Altera (now Intel) EPF6016ATI144-3N is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs) manufactured on a 0.42 µm CMOS process, integrating 16,000 gates (1,320 logic elements / 132 LABs) with 117 user I/O in a 144-pin TQFP (Thin Quad Flat Pack) package. Operating from a 3.3 V core supply, the device supports internal operation up to 142.86 MHz and provides SRAM-based configuration that can be loaded from a PROM or in-system via JTAG, enabling rapid design iteration. The "-3" speed grade combined with the industrial temperature range (-40 °C to +85 °C, suffix "I") and lead-free ("N") designation positions this part for mainstream industrial and telecom glue-logic applications. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) — itself a category of integrated circuit — that uses configurable logic blocks (LBs), programmable interconnect, and programmable I/O cells to implement arbitrary digital circuits after fabrication. FPGAs sit at the top of the programmable logic hierarchy: ASIC < Gate Array < CPLD < FPGA. The FLEX 6000 family represents Altera's mid-1990s cost-optimized SRAM FPGA architecture, positioned between their Classic and FLEX 10K families, and remains in long-term supply for industrial and aerospace refresh programs. Key features include 1,320 logic elements arranged in 132 Logic Array Blocks (LABs), 117 user I/O pins, embedded JTAG (IEEE 1149.1) boundary-scan support, and four dedicated inputs. The architecture is built around SRAM configuration cells with 4-input look-up tables (LUTs), per-LAB carry chains for fast arithmetic, and a continuous routing matrix. The device is in-system programmable through the ByteBlaster or BitBlaster download cables, supporting rapid prototyping and field upgrades without removing the part from the board. Typical applications include industrial control glue logic, telecom interface bridging, motor control peripheral integration, legacy M68000/i960 co-processor glue, and avionics display controllers where the FLEX 6000 family has established long-term qualified status. The 144-pin TQFP package exposes 117 user I/O, which is sufficient for wide parallel buses plus multiple serial channels in bridge applications. When designing with this device, pay attention to the JTAG chain order — the EPF6016 shares a JTAG bus with other Altera legacy parts (FLEX 10K, MAX 7000) and must be ordered correctly when multi-device programming is used. Decoupling requires 0.1 µF and 10 µF capacitors per VCCINT and VCCIO pin group; the device is sensitive to supply droop during configuration. Always validate the configuration PROM or in-system flash image against the Quartus II 13.0 service pack release, which is the last officially supported design software for the FLEX 6000 family.

EPF6016BC256-3 - 16K Gates FLEX 6000 FPGA, 256-BGA | Intel

The Intel EPF6016BC256-3 is a member of the FLEX 6000 family of programmable logic devices, delivering 16,000 usable gates (13,200 typical logic elements) in a 256-ball FineLine BGA package. The device is fabricated on a 0.42 µm CMOS SRAM process and supports 204 user I/O pins, making it well suited for high-I/O glue-logic, bus-interface, and state-machine designs that have outgrown a CPLD but do not justify a larger FPGA. What is an FPGA? A Field-Programmable Gate Array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable routing, and I/O cells that the user can define after manufacture via a configuration bitstream. FPGAs sit between simple PLDs/CPLDs (limited logic, deterministic timing) and ASICs (high NRE, long lead time). The FLEX 6000 family in particular targets cost-sensitive, high-volume applications such as consumer electronics, communications glue logic, and peripheral bridging - offering ASIC-like integration with the fast time-to-market of programmable logic. Key features of the EPF6016BC256-3 include a maximum internal frequency of 172 MHz (per the FLEX 6000 family datasheet), 5.0 V core supply operation, in-system programmability via an SRAM configuration cell, and JTAG-compliant boundary-scan test support (IEEE 1149.1). The 256-pin FineLine BGA offers high board-routing density with 204 usable I/Os - well above comparable 100-pin and 144-pin FLEX 6000 variants, enabling direct parallel-bus and 32-bit datapath interfaces. The architecture combines four-input look-up tables (LUTs) with fast interconnect and embedded memory, providing deterministic timing across commercial (0 °C to 85 °C) operating conditions. Designers can choose between Verilog HDL, VHDL, or schematic entry using the Altera/Intel Quartus II (or legacy MAX+PLUS II) design environments, with support for IP cores including UARTs, FIFOs, and PCI bridges. Typical applications include peripheral bridging (e.g., ISA-to-PCI, 8-bit/16-bit microprocessor bus expansion), industrial control glue logic, telecommunications backplane multiplexing, and consumer-electronics I/O expansion. The 5 V I/O tolerance allows direct connection to legacy logic without level shifters. When designing with this device, ensure the configuration mode (PS, PPS, JTAG, or serial) is selected correctly and that the 5 V core and I/O supplies are properly decoupled. The FineLine BGA-256 package requires careful PCB layout: matched-length traces to the configuration pins and a solid ground plane under the device are mandatory for clean signal integrity at the rated 172 MHz internal frequency.

EPF6016QC208

EPF6016QC208 - 16K FLEX 6000 FPGA, 5V, PQFP-208 | Altera/Intel

The Intel/Altera EPF6016QC208 is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs), integrating 16,000 equivalent gates and 1,320 logic cells in a 208-pin Plastic Quad Flat Pack (PQFP) package. Manufactured on a 0.42 um CMOS process and rated for 5 V operation, this device offers up to 171 user I/O pins and supports an internal frequency up to approximately 125 MHz, making it suitable for glue-logic, interface bridging, and modest state-machine applications. The 'QC208' suffix denotes the Plastic QFP package code with 208 pins, while the underlying family number (6016) indicates the gate/cell capacity. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows hardware engineers to implement arbitrary digital logic through a configuration bitstream loaded into on-chip SRAM. FPGAs sit at the top of the programmable-logic hierarchy: PLD -> CPLD -> FPGA -> system-on-chip (SoC) FPGA. The FLEX 6000 family specifically targets low-cost, high-volume applications where the integration of 5V-tolerant I/O eliminates level shifters and simplifies board design. Key features of the EPF6016QC208 include 132 Logic Array Blocks (LABs) each containing 10 Logic Elements (LEs), dedicated carry and cascade chains for high-speed arithmetic and wide-input functions, and configurable I/O cells that support 5.0V CMOS input thresholds (with appropriate pull-ups when interfacing to external 5V supplies). The device is available in commercial (0C to 70C) and industrial (-40C to 85C) temperature grades, and is supported by the legacy Altera MAX+PLUS II and Quartus design toolchains. From an architectural standpoint, the FLEX 6000 family employs an SRAM-based configuration memory, meaning the device is volatile and must be reconfigured at power-up from an external EPROM, flash, or microcontroller. Continuous Interconnects (CIRs) and Row/Column Interconnects (RIRs) provide predictable routing delays, and the FastTrack interconnect fabric connects LEs across the entire device via horizontal and vertical channels. MultiVolt I/O support simplifies mixed-voltage system design, while IEEE Std 1149.1 (JTAG) boundary-scan testing is provided for production board test. Typical applications include industrial control and glue logic, telecommunications line cards, ASIC prototyping, and bus-interface bridging (e.g., ISA, PCI, VME). The 5V I/O tolerance makes the EPF6016QC208 especially attractive in legacy industrial systems that retain 5V buses, where modern 3.3V-only FPGAs would otherwise require level-shifters. Because the part is mature and approaching end-of-life, designers are increasingly substituting it with FLEX 10K, MAX 7000, or Cyclone family equivalents in new designs. When designing with this FPGA, ensure that configuration storage (typically an EPC1 or EPC2 configuration EPROM) is correctly dimensioned for the EPF6016's bitstream size, and that the JTAG chain is properly terminated. Thermal management is generally not a concern at PQFP-208 power levels, but adequate decoupling (one 0.1 uF per VCC pin plus bulk capacitance) is essential for reliable SRAM configuration.

EPF6016QC208-2 - FLEX 6000 FPGA, 16K Gates, 208-PQFP | Intel

The Intel EPF6016QC208-2 is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs), delivering 16,000 usable gates, 1,320 logic elements, and 132 logic array blocks (LABs) in a 208-pin Plastic Quad Flat Pack (PQFP) package. Fabricated on a 0.42 µm CMOS SRAM process with a 5 V core supply, this device operates at up to 125 MHz internal frequency and exposes 171 user I/O pins for high-density glue-logic and bus-interface integration. A Field-Programmable Gate Array (FPGA) is a type of integrated circuit whose logic function is defined after manufacturing through a configuration bitstream stored in SRAM. FPGAs belong to the broader class of programmable logic devices (PLDs), which sit between fixed-function ASICs and software-driven processors in the design flexibility spectrum. Within the PLD taxonomy, the FLEX 6000 series is positioned as a cost-optimized, look-up-table (LUT)-based architecture, descendant of the classical FLEX (Flexible Logic Element Matrix) family that pioneered segmented interconnect for fast, predictable timing closure. Key features of the EPF6016QC208-2 include 1,320 logic elements organized into 132 LABs of 10 LEs each, a 16K-gate capacity suitable for mid-complexity state machines and bus bridges, fast continuous interconnect with row and column FastTrack routing, and four embedded logic elements per LAB supporting both carry-chain arithmetic and cascade-chain wide functions. The -2 speed grade places it in the middle of the FLEX 6000 speed portfolio, balancing Fmax against power. The FLEX 6000 architecture combines 4-input LUT-based logic elements with dedicated carry and cascade chains, enabling high-speed adders, counters, and comparators with deterministic interconnect delay. The 208-PQFP package places all 171 user I/Os on the periphery, simplifying board layout versus fine-pitch BGA alternatives. Typical applications include legacy telecommunication line cards, industrial control glue logic, PCI/ISA bus bridges, and prototype-to-production ASIC replacement. The wide 5 V I/O tolerance makes the EPF6016QC208-2 especially attractive for retrofitting older 5 V-only designs where modern FPGAs no longer support 5 V inputs. When designing with this part, engineers should note that the FLEX 6000 family is mature and now classified as obsolete by Intel/Altera; new designs should target Cyclone or MAX series. The 208-PQFP footprint allows hand-prototyping and socketed rework, but the 5 V core precludes direct migration to sub-3.3 V platforms without level translation. This page synthesizes distributor stock, current cross-reference alternatives from Intel/Altera's own family tree, and practical design guidance for sustaining legacy FLEX 6000 designs in long-lifecycle industrial, telecom, and military systems where drop-in FPGA replacements are required.

EPF6016QC208-2N - FLEX 6000 FPGA, 1320 LEs, 171 I/O, PQFP-208 | Intel

The Intel (formerly Altera) EPF6016QC208-2N is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs), delivering 1,320 logic elements (equivalent to approximately 16,000 usable gates) in a 208-pin Plastic Quad Flat Pack (PQFP-208 / QFP-208) surface-mount package. The device is fabricated on a 5 V CMOS process, operates from a 5 V supply, and supports a maximum internal toggle frequency of 125 MHz, making it suitable for glue-logic, bus-interface, and moderate-complexity state-machine applications of the late 1990s and early 2000s design era. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that uses a matrix of configurable logic blocks (CLBs), programmable interconnect, and I/O cells to implement arbitrary digital circuits. Within the broader semiconductor hierarchy, FPGAs sit between simple SPLDs/CPLDs (smaller density) and structured ASICs (higher density, non-programmable). The FLEX 6000 family belongs to Intel's classic Altera-era product line, sitting below the FLEX 10K and APEX families in density while offering low-cost replacement for fixed-logic gate arrays and fast prototyping turnaround via in-system SRAM-based configuration. Key specifications of the EPF6016QC208-2N include 1,320 logic elements organized into 132 logic array blocks (LABs), 171 maximum user I/Os, an internal frequency of 125 MHz, and on-chip SRAM-based configuration memory. The "-2" speed grade places this part in a moderate performance bin relative to the "-3" faster grade. The PQFP-208 (also referred to as BFQFP-208 or QFP-208) package provides fine-pitch gull-wing leads on a 28 mm × 28 mm body suitable for socketed or hand-soldered prototypes, though modern production typically prefers lead-free QFP packages. Typical applications include industrial control interfaces, telecommunications glue logic, peripheral bus bridging (PCI, ISA, VME), instrumentation front-ends, and legacy embedded designs. Designers often select this part when maintaining or replicating existing production systems, when an exact long-life-cycle component is required for medical or aerospace follow-on orders, or in educational settings where low-cost FPGAs are introduced. The PQFP package is also advantageous for prototype bring-up since the wide lead pitch is easier to inspect and rework than fine-pitch BGA alternatives. Key design considerations include providing a stable 5 V supply with adequate decoupling, configuring the device through a standard JTAG or EPC configuration interface, and respecting the I/O bank's voltage compatibility. Because the EPF6016QC208-2N is a legacy 5 V part nearing end-of-life, designers should verify last-time-buy dates with Intel/Altera distributors before committing to new designs.

EPF6016QC208-3 - FLEX 6000 FPGA 16K Gates 1320 Cells | Altera

The Altera (Intel) EPF6016QC208-3 is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs) fabricated on a 5.0V CMOS process, offering 16,000 typical gates and 1,320 logic elements across 132 Logic Array Blocks (LABs). The -3 speed grade denotes the slowest commercial speed bin of the family, prioritizing timing-closure margin over absolute fMAX, and the device is housed in a 208-pin Power Quad Flat Pack (PQFP / QFP-208) package with 171 usable user I/Os. It operates from a single 5.0V supply (VCCINT = 5.0V, VCCIO = 3.3V or 5.0V tolerant) and is targeted at glue-logic, bus-interface, and cost-sensitive ASIC-replacement designs in industrial, telecom, and embedded-control applications. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs / LEs), programmable interconnect, and I/O cells, all of which can be re-programmed in the field to implement arbitrary digital logic. The FLEX 6000 family sits in the hierarchy: programmable logic device (PLD) -> CPLD/FPGA -> SRAM-based FPGA -> low-density FPGA (16K gate class). Each LE in the EPF6016 contains a 4-input look-up table (LUT), a programmable register, and dedicated carry and cascade chains that accelerate arithmetic and wide fan-in functions across LABs, providing deterministic, predictable timing for synchronous state machines and datapaths. Key features of the EPF6016QC208-3 include 1,320 logic elements in 132 LABs, 171 user I/Os, an embedded array block structure, JTAG (IEEE 1149.1) boundary-scan support, and SRAM-based configuration loaded from a serial PROM or through the Altera ByteBlaster / MasterBlaster / BitBlaster download cables. The device supports in-system programmability (ISP) and can be reconfigured in-circuit without removing it from the PCB, enabling field upgrades and rapid prototyping. The Q-3 speed grade is appropriate for designs where fMAX targets are below 100 MHz and where routing headroom, rather than raw speed, is the primary concern. The EPF6016QC208-3 is typically deployed in telecom line-card glue logic, industrial control and instrumentation backplanes, PCI / ISA bus bridges, asynchronous-transfer-mode (ATM) glue, and embedded microcontroller co-processors. The 208-pin PQFP footprint has a generous 0.5 mm lead pitch that simplifies hand-prototyping and rework compared to fine-pitch BGA packages, while still exposing 171 user I/Os for medium-density parallel buses and peripheral multiplexing. Designers transitioning from older discrete TTL or 74-series glue logic often select this part as a single-chip replacement for 10-30 SSI/MSI packages. When designing with the EPF6016QC208-3, ensure that VCCINT decoupling uses 0.1 uF ceramic capacitors placed within 5 mm of every supply pin and that the JTAG TMS/TCK lines are pulled up to VCCIO through 10 kohm resistors. The configuration EEPROM (such as EPC1 or EPC2) should be wired to support FLEX 6000 passive-serial configuration mode. Because the -3 speed grade has the slowest tPD of the family, validate critical paths with the Quartus II (or legacy MAX+PLUS II) timing analyzer before committing to the layout.

The Altera (now Intel) EPF6016QC208-3N is a member of the FLEX 6000 family of SRAM-based FPGAs (Field-Programmable Gate Arrays), fabricated on a 0.42 µm CMOS process and supplied in a 208-pin Power Quad Flat Pack (PQFP) package. The device integrates 16,000 usable gates organized into 1,320 logic cells distributed across 132 Logic Array Blocks (LABs), and exposes 171 user I/O pins, supporting 5.0 V core and 3.3 V/5.0 V tolerant I/O operation. Maximum internal operating frequency is rated at 125 MHz per the FLEX 6000 datasheet family specification, with internal toggle rates reaching 172 MHz on fast paths. What is a FLEX 6000 FPGA? The FLEX 6000 is a second-generation Altera SRAM-based FPGA family introduced in the mid-1990s, designed as a low-cost programmable alternative to gate-array ASICs for high-volume glue-logic, bus-interface, and state-machine applications. The family uses a continuous-row LAB architecture with look-up table (LUT)-based logic elements and a hierarchical interconnect, sitting in the broader taxonomy of programmable logic devices (PLD) -> CPLD/FPGA -> SRAM-based FPGA -> FLEX 6000 family. Compared with its predecessor MAX 7000 CPLDs, FLEX 6000 devices offer true register-rich synchronous logic and higher gate density. The EPF6016QC208-3N features MultiVolt I/O supporting 3.3 V and 5.0 V interfaces, allowing direct connection to 5 V CMOS inputs when VCCIO is tied to 3.3 V with a pull-up to 5 V. The device is configured via a serial configuration EPROM or the Altera ByteBlaster download cable, and supports in-system programmability through JTAG (IEEE 1149.1 boundary-scan). Internal pull-up resistors and IOL current specification must be observed when designing external pull-ups for mixed-voltage systems. Typical applications include bus-interface bridges (PCI, ISA, VME), peripheral controllers, custom state machines, industrial control glue logic, and prototyping platforms where fast design iteration is required. The 208-pin PQFP provides generous I/O count for medium-complexity designs while remaining hand-solderable for prototype work. When designing with this part, ensure VCCIO is decoupled with at least 0.1 µF ceramic capacitors placed within 6 mm of each supply pin, and follow Altera's configuration device selection guidelines for the appropriate EPC1/EPC2 configuration EPROM.

EPF6016QC240 - FLEX 6000 FPGA, 16K Gates, 240-Pin PQFP | Intel

The Intel (formerly Altera) EPF6016QC240 is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs) fabricated on a 0.42 µm CMOS process and offering 16,000 typical gates with 1,320 logic elements across 132 Logic Array Blocks (LABs). The device is offered in a 240-pin Power Quad Flat Pack (PQFP / BFQFP) package and supports up to 199 user I/O pins with 5.0 V tolerant I/O banks that can also be configured for 3.3 V operation. According to the manufacturer datasheet, the device operates from a 5 V core supply with separate VCCIO rails, and is qualified over the commercial 0 °C to 85 °C temperature range. A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs or LABs), programmable routing channels, and configurable I/O cells. FPGAs occupy a position in the programmable logic hierarchy: PLD (Programmable Logic Device) -> CPLD (Complex PLD) -> FPGA (Field-Programmable Gate Array) -> programmable logic -> semiconductor IC. FPGAs like the EPF6016QC240 are typically used to implement glue logic, custom state machines, bus interfaces, and small to medium-sized parallel processing pipelines, bridging the gap between fixed-function ASICs and software running on a microcontroller. Key differentiating features of the EPF6016QC240 include 1,320 logic cells, 132 LABs, 199 maximum user I/Os, and a JTAG-compliant IEEE 1149.1 boundary-scan test interface for in-system configuration. The carry-chain architecture supports high-speed arithmetic functions such as counters and adders, while the cascade chain implements wide-input functions such as comparators with minimum delay. Carry and cascade chains connect LEs 2 through 10 in each LAB and propagate across all LABs in the same row half. The FLEX 6000 family uses SRAM-based configuration cells, allowing in-field re-programmability via the serial configuration scheme. Typical applications include legacy industrial control interfaces, glue logic in PCI bridge designs, custom peripheral controllers for embedded systems, and bus-protocol bridges (for example, between ISA and a custom peripheral bus). The 5 V I/O tolerance also made the FLEX 6000 family a popular drop-in for designs transitioning from 5 V TTL logic to programmable logic without level translators. When designing with this device, note that the FLEX 6000 family is now in End-of-Life status. Designers of new products should consider the MAX II, MAX V, or Cyclone series for new designs, while the EPF6016QC240 remains appropriate for sustaining engineering and long-life-cycle industrial systems where re-qualification is cost-prohibitive. The 240-pin PQFP package requires careful PCB layout with adequate power and ground planes to support the simultaneous switching output (SSO) limits documented in the FLEX 6000 family data sheet. This page synthesises distributor pricing tiers, drop-in compatible speed-grade and package variants of the same family, and practical design notes that go beyond what the manufacturer datasheet alone provides, helping engineers quickly verify lifecycle status and identify available substitutes.

The Intel EPF6016QC240-2 is a FLEX 6000 family Field Programmable Gate Array (FPGA) delivering 16,000 typical gates (with up to 24,000 maximum system gates), 1,320 logic elements distributed across 132 Logic Array Blocks (LABs), and 199 user I/Os, housed in a 240-pin Plastic Quad Flat Pack (PQFP / BFQFP) package. It is built on a 0.42 micrometer CMOS SRAM process with four layers of metal interconnect, supports a 5 V supply core, and is specified to operate over the commercial 0 to 85 degrees C temperature range. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the density of a gate array with the flexibility of in-system programmability. Hierarchically, an FPGA sits above a CPLD (Complex Programmable Logic Device), below a structured ASIC, and within the broader family of programmable logic devices; FPGAs are widely used for glue logic, state-machine control, bus interfacing, and high-volume prototyping in lieu of gate arrays. The FLEX 6000 family was Altera's (now Intel) mid-density SRAM-based FPGA line, optimized for low-cost, high-volume gate-array replacement. Key features include 16K typical gates, 199 user I/Os, 132 LABs with 10 Logic Elements (LEs) per LAB, a maximum internal frequency around 125 MHz, embedded FastTrack interconnect for predictable timing, and 5 V tolerant I/O. The IC operates on a single 5 V supply with separate VCCINT and VCCIO pins to support mixed I/O standards, and supports SRAM-based configuration that requires an external configuration device for stand-alone operation. Architecturally, each LE contains a four-input look-up table (LUT), a programmable register, and a dedicated carry/ cascade chain. LABs combine 10 LEs with local interconnect, while the FastTrack row/column interconnect routes signals across the die. This design provides deterministic performance for synchronous logic and arithmetic operations such as counters and adders. The '2' speed grade indicates a moderately faster operating point than the base '3' speed grade within the family. Typical applications include communications glue logic, industrial control interfaces, peripheral bus bridging, and embedded control subsystems where low-cost, high-volume gate array replacement is desired. Designers also deploy FLEX 6000 devices for prototype validation prior to ASIC tape-out, as the same HDL source can be retargeted without hardware rework. When designing with the EPF6016QC240-2, ensure the configuration scheme (typically EPC2 or EPC1) is correctly selected and that JTAG pins (TDI, TDO, TMS, TCK) are accessible for in-system programming. Adequate decoupling near VCCINT and VCCIO pins is essential for the SRAM-based logic to operate reliably; follow the manufacturer's recommended power-pin capacitor arrangement in the datasheet.

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.

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.

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.

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.

EPF6016QI208-3N - FLEX 6000 FPGA 16K Gates 171 I/O 208-PQFP | Intel

The Intel EPF6016QI208-3N is a member of the FLEX 6000 family of SRAM-based Field Programmable Gate Arrays (FPGAs), delivering 16,000 usable gates, 1,320 logic elements (LEs) and 171 user I/Os in a 208-pin Power Quad Flat Pack (PQFP / BFQFP) package. Built on a 0.42 µm CMOS process with a 5 V core supply, the device supports an internal operating frequency up to 125 MHz and provides 132 Logic Array Blocks (LABs) with embedded interconnect, making it suitable for glue-logic, bus-interface and state-machine consolidation in legacy and industrial designs. An FPGA (Field Programmable Gate Array) is a programmable integrated circuit that combines configurable logic blocks, programmable interconnect, and I/O cells on a single die. The FLEX 6000 family specifically targets low-cost, high-volume designs as an alternative to gate arrays, allowing rapid design changes during prototyping without NRE charges. FPGAs sit in the programmable-logic hierarchy alongside CPLDs and serve as the highest-density programmable logic option for logic integration, glue logic, and pre-ASIC prototyping. Key features include 1,320 logic elements distributed across 132 LABs, 171 user I/Os, an internal frequency up to 125 MHz, on-chip SRAM configuration memory, JTAG-based IEEE 1149.1 boundary-scan testing support, and multi-voltage I/O support. 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.

The Intel (formerly Altera) EPF6016TC144-2 is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs) fabricated on a 0.42 µm CMOS process and supplied in a 144-pin LQFP/TQFP package. The device integrates 16,000 typical gates organized as 1,320 logic elements (cells), with up to 117 usable user I/O pins, and is rated for a maximum internal operating frequency of approximately 125 MHz at 5 V nominal core supply. According to distributor listings on Octopart and DigiKey, the device is described as "FLEX® 6000 Field Programmable Gate Array (FPGA) IC 117 1320 144-LQFP," confirming the 144-LQFP package and 117 I/O count. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the density and performance of application-specific integrated circuits (ASICs) with the flexibility of in-system reprogrammability. Within the semiconductor hierarchy, an FPGA sits above simple PLDs and complex PLDs (CPLDs), and below full-custom ASICs. FPGAs are widely used for digital logic prototyping, glue logic, custom interface bridging, and pre-production ASIC emulation. The FLEX 6000 family specifically occupies the low-density, low-cost end of the Altera/Intel FPGA portfolio, optimized for glue logic and high-volume gate-array replacement. Key specifications of the EPF6016TC144-2 include 16K typical gates, 1,320 logic cells, 117 user I/Os, a maximum internal frequency of 125 MHz, 5 V core supply, and 144-pin TQFP surface-mount packaging.

The device supports in-system programmability via the IEEE 1149.1 JTAG interface and Altera's classic configuration schemes, making it suitable for both prototyping and production. Architecturally, the FLEX 6000 family employs a look-up table (LUT)-based logic element with a continuous FastTrack interconnect routing fabric. Each logic element contains a 4-input LUT, a programmable register, and carry-chain support, enabling efficient implementation of arithmetic and state-machine designs. Embedded array blocks (EABs) provide dedicated memory functions for small FIFOs and ROM/RAM tables. Typical applications include low-cost glue logic replacement, communications protocol bridging, industrial control and factory automation, pre-silicon ASIC prototyping, and educational development platforms. Engineers also deploy FLEX 6000 devices in legacy telecom line cards, motor-control interface logic, and custom sensor aggregation. When designing with the EPF6016TC144-2, note that 5 V tolerance is a defining feature of this family, unlike newer low-voltage FPGAs. Use the Quartus II (or MAX+PLUS II) toolchain for design entry, synthesis, fitting, and programming file generation. Ensure decoupling is sufficient for the 5 V rail and that JTAG chain integrity is preserved across multi-device boards.

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
EPF6016TC144-3

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.
