Built on a 0.42 µm CMOS SRAM process with 3.3 V core supply and 71 user I/O pins, this device is specified for industrial-grade temperature operation and offers a maximum internal frequency of 166.67 MHz. The 'I' suffix in the part number designates the industrial temperature range and the TQFP-100 package outline. A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that allows designers to configure arbitrary digital logic functions after PCB assembly, sitting in the broader hierarchy of digital logic -> programmable logic -> complex programmable logic device (CPLD) / FPGA -> system-on-chip integration. The FLEX 6000 family targets glue-logic, bus-interface, and low-to-medium density state-machine applications where ASIC NRE is not justified. It uses a look-up-table-based architecture backed by SRAM configuration memory, requiring external configuration storage on every power-up. Key features include 88 logic array blocks (LABs), 71 usable I/O pins supporting 5V-tolerant input levels with 3.3V output swing, on-chip ISP (in-system programmability) via the IEEE 1149.1 JTAG interface, and multiVolt I/O support for interfacing with both 5.0 V and 3.3 V buses. The 0.42 µm four-layer metal process delivers deterministic timing with pin-to-pin propagation delays in the nanosecond range, well suited for control-plane and bridging applications. The EPF6010ATI100-2N supports the Altera MAX+PLUS II and Quartus development flows, with deterministic place-and-route results available through the fitter engine. Configuration is performed via serial or parallel PROM using the built-in EPC configuration port, allowing rapid prototyping and field upgrades via JTAG. Typical applications include industrial control glue logic, parallel bus bridges (e.g., PCI-to-ISA, ISA-to-ISA), motor-control state machines, low-density protocol converters (UART/SPI multiplexing), and legacy peripheral controllers in long-lifecycle platforms. The TQFP-100 package is hand-solderable for prototypes and supports automated reflow for volume production. When designing with this device, ensure the JTAG chain is properly terminated with the TCK pull-up and TDI/TMS pull-ups required by IEEE 1149.1. A reset supervisor must hold nCONFIG low until all power rails are stable to prevent spurious configuration.

The FLEX 6000 family uses a LUT-based fabric that delivers higher logic density than the older MAX 7000 CPLDs while remaining low-cost and low-power. Key features include 1,320 logic elements (LEs), 132 LABs, 81 user I/Os, JTAG (IEEE 1149.1) boundary-scan support, and a 4-input LUT structure that simplifies synthesis tool mapping. The 100-LBGA FineLine BGA package provides high-density board routing with a 1.0 mm ball pitch and a footprint of 11x11 mm, ideal for space-constrained designs. The device supports in-system programmability via the dedicated configuration interface and standard SRAM configuration bitstream storage. Architecturally, the FLEX 6000 uses an SRAM cell to hold configuration data, allowing unlimited reconfiguration. Each LAB contains 8 LEs, and each LE combines a 4-input LUT, a programmable register, and dedicated carry-chain logic for arithmetic. The interconnect is a continuous FastTrack row/column structure that delivers predictable timing and simplifies static timing closure compared with earlier segmented FPGA architectures. Typical applications include glue logic replacement, bus bridging, peripheral control, low-complexity state machines, and prototype ASIC verification in industrial, communications, and consumer products. Engineers select the FLEX 6000 family when they need more logic than a CPLD but want to avoid the cost and complexity of high-density FPGAs such as Cyclone or Stratix. When designing with the EPF6016AFC100-2, ensure that your power-decoupling network matches Altera's FLEX 6000 reference design and that JTAG chain ordering is consistent with board-level boundary-scan planning. The 100-LBGA package requires careful PCB layout for the ball-pad fan-out - use of 0.5 mm via-in-pad or dog-bone fan-out is recommended to avoid solder joint reliability issues.

The Intel (formerly Altera) EPF6016AFC256-2 is a member of the FLEX 6000 family of Field-Programmable Gate Arrays (FPGAs), delivering 16,000 typical gates, 1,320 logic elements, and 171 user I/Os in a 256-ball FineLine BGA (FBGA) package. It is built on a 0.42 um CMOS SRAM process with a 3.3 V core supply and supports in-system programmability through an IEEE 1149.1 JTAG interface, making it suitable for low-cost, high-volume programmable logic applications. A Field-Programmable Gate Array (FPGA) is a type of integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that engineers can re-program repeatedly in the field. Within the broader semiconductor taxonomy, an FPGA sits inside the category of programmable logic devices (PLDs), which also include Complex PLDs (CPLDs) and Simple PLDs (SPLDs); the FLEX 6000 family itself uses an SRAM-based look-up-table architecture, placing it architecturally closer to modern FPGAs than to fuse-based CPLDs. This SRAM-backed fabric is what enables unlimited re-programmability but also means the configuration must be reloaded at every power-up from a separate PROM or flash device. Key features of the EPF6016AFC256-2 include 1,320 logic elements, 4 embedded array blocks (EABs) of 2,048 bits each for on-chip RAM or ROM, 171 maximum user I/Os, and a typical internal frequency of up to 172 MHz. The device supports LVCMOS, LVTTL, and other I/O standards through its flexible I/O element (IOE) structure, and offers dedicated clock-locked loops and boundary-scan testability. Operating temperature is 0C to 85C (commercial grade), and supply voltage is 3.0 V to 3.6 V. Typical applications include glue logic replacement, bus-interface bridging, custom peripheral implementation, telecommunications line cards, industrial control and automation, and prototyping for ASIC or gate-array designs. The wide I/O count (171) makes the device especially attractive for designs that have many parallel buses or memory interfaces. Engineers also use it as a fast design-change vehicle during ASIC prototyping, where design iterations need to be turned around in hours rather than weeks. When designing with the EPF6016AFC256-2, allocate a JTAG chain header on the PCB, reserve a serial configuration device footprint (such as an EPC2 or EPC8), and ensure decoupling is placed close to every VCCINT and VCCIO pin pair. A 4-layer PCB with solid ground and power planes is strongly recommended because the 0.42 um process is sensitive to power-supply noise. This page synthesizes distributor pricing, drop-in alternatives from the FLEX 6000 family, and practical design notes not found in the manufacturer datasheet, giving engineers a single decision-grade reference for sourcing this legacy Altera FPGA.

The device integrates 132 Logic Array Blocks (LABs) and is built on a look-up-table (LUT) fabric optimized for high-volume glue-logic and gate-array replacement designs. A Field Programmable Gate Array (FPGA) is a reconfigurable semiconductor device containing an array of programmable logic blocks, interconnect, and I/O cells that can be customized after manufacturing via a configuration bitstream. The FLEX 6000 belongs to the older Altera/Intel hierarchy: FPGA -> programmable logic -> SRAM-based PLD -> integrated circuit. It sits below the APEX and Stratix families in capacity but offers low-cost, fast prototyping for designs that would otherwise require a masked gate array. Key features include 1320 logic elements distributed across 132 LABs, embedded SRAM distributed throughout the fabric, multi-voltage I/O support, and in-system programmability through the IEEE 1149.1 JTAG interface. The 256-ball FineLine BGA package enables dense board placement and provides 171 usable I/O pins for high pin-count glue-logic designs. Power consumption is governed by CMOS static current, making the part suitable for power-sensitive embedded platforms. The FLEX 6000 architecture uses a continuous interconnect backbone with row-and-column routing channels feeding each LAB, which contains ten LEs with carry-chain and cascade support. Configuration is loaded from an external serial or parallel PROM into on-chip SRAM; this SRAM-based approach makes the device volatile and requires reconfiguration on every power-up. The part is fabricated on a 0.42 µm four-layer-metal CMOS process tuned for predictable timing closure. Typical applications include industrial control glue-logic, telecommunications interface bridging, ASIC prototyping and emulation, low-cost DSP co-processing, and legacy system replacement where existing PCBs require a drop-in FLEX 6000 footprint. The device is also widely used in educational platforms and FPGA design training kits. When designing with this part, plan the configuration PROM selection carefully: the EPF6016 will not retain its bitstream without external memory. Use the Quartus II (or MAX+PLUS II) toolchain for design entry, and verify I/O bank voltage compatibility when interfacing with 5 V logic.

Manufactured on a 0.42 µm CMOS process, it operates from a 3.3 V core supply at a maximum internal frequency of 166.67 MHz. The device belongs to the older SRAM-based FLEX 6000 programmable logic family and is targeted at low-cost, high-volume glue-logic and bus-interface applications. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose logic functionality is defined by user-supplied SRAM configuration data rather than by hard-wired mask layers, placing it in the broader taxonomy of programmable logic devices (PLD) alongside CPLDs and SPLDs. FPGAs sit at the top of the programmable logic hierarchy, offering the highest logic density and richest I/O feature set at the cost of higher unit price and the need for an external configuration memory. The FLEX 6000 series in particular was Altera's mid-1990s cost-optimized family, positioned between the simpler MAX 7000 CPLDs and the higher-density FLEX 10K series, and was widely used in telecom glue logic, peripheral bridging, and industrial control boards. Key features of the EPF6016AQC208-2 include a 132-LAB architecture with 10 Logic Elements per LAB, four embedded Logic Array Block inputs per LAB, fast continuous interconnect routing, multiVolt I/O supporting 5.0 V, 3.3 V, and 2.5 V interfacing, and in-system configurability through the IEEE 1149.1 JTAG interface. Each I/O pin includes a tri-state buffer with programmable slew-rate control and an optional pull-up resistor, simplifying board-level integration with mixed-voltage buses such as PCI, ISA, and 68xxx processor interfaces. The device supports configuration via EPROM, microcontroller, or JTAG, with a dedicated configuration EPROM interface that allows automatic load on power-up. This makes the EPF6016AQC208-2 suitable for production volumes where a separate configuration memory is acceptable, while preserving the flexibility of field upgrades via JTAG. The 208-pin PQFP (also referenced as BFQFP) provides 171 usable I/O pins with seven dedicated inputs (CLK, OE, CONFIG_DONE, nSTATUS, nCONFIG, MSEL, JTAG pins). Typical applications include peripheral bridging (PCI to local bus glue), industrial control and instrumentation front-ends, telecommunications line cards, factory automation backplanes, and legacy embedded system upgrades. The wide I/O voltage tolerance (5 V tolerant inputs on a 3.3 V core) allows direct connection to legacy 5 V microprocessors without external level shifters. When designing with this part, note that the EPF6016AQC208-2 is now NRND/EOL — supply is limited to remaining distributor inventory, and the 208-pin PQFP package requires substantial PCB area (approximately 30 × 30 mm). New designs should target Altera/Intel MAX II, MAX V, or Cyclone IV E as modern replacements, accepting that footprint migration is mandatory.

The device operates across the commercial 0°C to 85°C temperature range and is supplied in a 208-pin PQFP (also referenced as BFQFP/PQFP-208) with gull-wing leads. The -2 speed grade offers a balance of timing margin and cost, supporting system clock frequencies up to 166.67 MHz at the internal logic array. The SRAM-based configuration fabric means the device must be configured at every power-up using a serial configuration EPROM (e.g., EPC1/EPC2) or via JTAG boundary-scan download. Typical applications include telecommunications glue logic, industrial control and factory-automation backplanes, PCI bus interface bridges, prototyping platforms that later migrate to APEX 20K or Cyclone families, and legacy upgrade paths for original FLEX 6000 designs. The wide I/O count (171) and 3.3 V core supply also suit mixed-voltage 5 V-tolerant interface designs. When designing with this part, note that it has been in the legacy / last-time-buy category for many years - verify supply chain availability before starting a new design, and consider pin-compatible FLEX 6000 siblings (EPF6016AQC208-1, EPF6016AQC208-2) or migration to the Cyclone family for new projects.

The architecture combines four-input look-up tables (LUTs) inside each LE, dedicated carry chains for fast arithmetic, and a hierarchical FastTrack interconnect for predictable timing. The 3.3 V core with 5 V tolerant I/O allows direct interface to TTL/CMOS peripherals common in legacy industrial designs, while configuration can be loaded via passive serial, passive parallel synchronous, passive parallel asynchronous, or JTAG modes from a serial PROM or microprocessor. Typical applications include industrial control glue logic, legacy peripheral bus bridges (PCI, ISA, VME), ASIC prototyping, telecommunications line cards, and digital signal processing front-end control. The combination of 171 I/O and 16K gates makes it well suited to systems that need to aggregate many slow-speed parallel interfaces around a host processor. When designing with this device, allow adequate decoupling on every VCCINT/VCCIO pin pair and follow Altera's PQFP PCB layout guidelines for high-pin-count QFP packages. Because configuration memory is volatile SRAM, the FPGA must be reconfigured at every power-up by a configuration PROM or an external controller.

The device exposes dedicated clock and global routing networks for high-fanout signal distribution across the fabric, with multi-volt I/O permitting 5.0V tolerance on input pins when the VCCIO rail is set to 3.3V. The FLEX 6000 architecture separates logic resources into LABs interconnected by a continuous routing matrix called the FastTrack Interconnect. Each LAB contains 10 logic elements, each built around a 4-input LUT with a programmable register, allowing efficient implementation of wide-input combinational and sequential logic. Configuration bitstreams are loaded from an external EPROM, flash, or via the JTAG port, and the SRAM cell array can be reconfigured in milliseconds, supporting rapid iteration and field upgrades. Typical applications include telecom interface bridging, industrial control and factory automation glue logic, low-density DSP pre-processing and filtering, peripheral bus controllers, and legacy system replacement of TTL/CMOS gate-array designs. The 208-PQFP package with 0.5mm pitch remains popular for prototype boards, evaluation kits, and long-lifecycle industrial products where surface-mount BGA migration is undesirable. When designing with this part, plan for an external configuration PROM (such as the EPC2 or EPC8) because the SRAM-based fabric loses configuration on power-down. Use the Quartus II or MAX+PLUS II development toolchain (legacy versions) for synthesis, place-and-route, and bitstream generation. Ensure decoupling capacitors are placed within 5mm of every VCC and GND pin pair.

Built on a 0.42 µm CMOS SRAM process, the device integrates 1,320 logic elements (LEs), 16,000 typical gates, and a maximum of 132 user I/O pins operating at 3.3 V I/O with a 5.0 V tolerant input option. The "A" suffix designates the higher-performance -3 speed grade (commercial), optimized for medium-density glue logic, bus interfacing, and state-machine consolidation in cost-sensitive industrial, communications, and consumer designs. A field-programmable gate array (FPGA) is a semiconductor integrated circuit that engineers can configure after manufacturing to implement custom digital logic functions. FPGAs sit within the programmable logic hierarchy alongside CPLDs, PALs, and GALs, but offer higher logic density, distributed register-rich architectures, and on-chip SRAM configuration memory. The FLEX 6000 family specifically targets low-to-mid density glue-logic replacement of discrete 74-series TTL and 4000-series CMOS parts, while providing non-volatile in-system reconfigurability through external configuration memory (EPC2, EPC1441). Key features of the EPF6016AT1144-3N include 16,000 typical gates (24,000 maximum), 1,320 logic elements arranged in logic array blocks (LABs), 16,704 RAM bits distributed across embedded array blocks (EABs), and 132 user I/O pins. The device supports in-system programmability (ISP) via the ByteBlasterMV or BitBlaster download cable, multi-voltage I/O (MVIO) operation, and IEEE 1149.1 boundary-scan test (JTAG). The 144-pin TQFP package provides a robust plastic surface-mount footprint for industrial-temperature operation and automated assembly. The FLEX 6000 architecture employs a four-input look-up table (LUT) per logic element, fast carry chains for arithmetic operations, and dedicated cascade chains for wide fan-in functions. Each LE contains a programmable register that can be configured as D, T, JK, or SR flip-flop with independent clock, clock-enable, and clear/preset controls. Embedded array blocks (EABs) deliver up to 2,048 bits of dual-port RAM per block, supporting FIFO buffers, ROM look-ups, and arithmetic coefficient storage. The continuous FastTrack interconnect routes signals across all LABs and EABs with predictable, deterministic timing. Typical applications include industrial control and factory automation glue logic, telecommunications line-card bus interfaces, consumer electronics display controllers, networking peripheral bridges, and embedded system I/O expansion. The EPF6016AT1144-3N is also widely used in legacy PCI bus interfaces, microcontroller peripheral expansion, and as a configuration-memory controller in multi-FPGA systems. Its moderate density and low non-recurring engineering (NRE) cost make it an excellent choice for low-volume production or prototyping where ASIC conversion is not economically justified. When designing with this device, ensure the supply rails (VCCINT 3.3 V and VCCIO 3.3 V or 2.5 V) are decoupled with 0.1 µF ceramic capacitors placed within 6 mm of every VCC pin, and that the JTAG TCK signal is properly terminated to avoid configuration errors. Designers migrating from MAX 7000 or MAX 3000 CPLDs to FLEX 6000 should be aware that FLEX 6000 is SRAM-based and loses configuration on power-down, requiring an external configuration PROM such as the EPC2 or EPC1441.

The Intel (formerly Altera) EPF6016ATC100-1 is a FLEX 6000 family Field-Programmable Gate Array (FPGA) containing approximately 16,000 gates, packaged in a 100-pin Thin Quad Flat Pack (TQFP) surface-mount package. The device integrates 1,320 logic elements (LEs) organized into 132 Logic Array Blocks (LABs) and provides 81 user I/O pins with an internal operating frequency up to 172 MHz, making it well suited for glue-logic, bus-interface, and high-volume gate-array replacement designs. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all of which can be reconfigured by the end user after manufacture. FPGAs sit in the broader hierarchy of digital integrated circuits as programmable logic -> logic ICs -> integrated circuits -> semiconductors. The FLEX 6000 family specifically targets low-cost, high-volume applications where the design flexibility of an FPGA is required but the very high gate counts of larger FLEX 10K or APEX families are unnecessary. Key features of the EPF6016ATC100-1 include 1,320 LEs distributed across 132 LABs, 81 available user I/O pins, an internal clock frequency ceiling of 172 MHz, in-system programmability via SRAM configuration cells, and multi-voltage I/O support. The "ATC" speed grade and -1 temperature suffix designate a commercial-temperature device (0°C to +85°C) in the standard AC speed bin, while the "100" package code indicates the 100-TQFP footprint. The device operates from a 3.3 V core supply and supports 5.0 V tolerant I/O, simplifying interface to legacy TTL logic. Architecturally, the FLEX 6000 family employs a continuous interconnect structure called the FastTrack that links every LAB to every other LAB through horizontal and vertical routing segments, providing predictable and fast signal propagation. Each LAB contains 10 LEs with a local interconnect, and each LE contains a 4-input look-up table (LUT), a programmable flip-flop, and dedicated carry/control logic for arithmetic and counter applications. The device stores its configuration in SRAM cells, which means it must be reconfigured at every power-up from a serial ROM or microcontroller. Typical applications for the EPF6016ATC100-1 include bus-bridging between microprocessors and peripherals, glue-logic replacement in telecommunications backplanes, custom state machines in industrial controllers, peripheral interface adapters, and prototyping of gate-array designs prior to ASIC conversion. Because the FLEX 6000 family was originally positioned as a low-cost programmable alternative to mask-programmed gate arrays, the EPF6016ATC100-1 is most often seen in legacy 3.3 V designs or as a hardware-revision-friendly replacement for discrete TTL/CMOS logic boards. When designing with this part, the engineer must allocate a configuration memory device (EPC2 or compatible) because the SRAM-based configuration is volatile. Additionally, all unused I/O pins should be left floating or driven to a defined state, and the JTAG chain should be considered for boundary-scan test access. The 100-TQFP package has a 14 mm x 14 mm body and is suitable for standard surface-mount assembly lines.

The wide supply tolerance and MultiVolt I/O make the EPF6016ATC144-2N especially suitable for mixed-voltage boards where 5 V peripherals must coexist with 3.3 V logic. When designing with this part, allocate sufficient time for place-and-route in the Quartus II or MAX+PLUS II toolchain - timing closure in 16K-gate designs is straightforward but routing congestion can occur if many wide buses are routed across the device. Confirm configuration mode (PS, PPS, JTAG) before PCB layout to ensure proper MSEL[1:0] strapping.

EPF6016ATC144-3 - FLEX 6000 FPGA, 16K Gates, 1320 Cells | Intel
The Intel EPF6016ATC144-3 is a FLEX 6000 family Field Programmable Gate Array (FPGA) integrating 16,000 gates, 1,320 logic cells, and 117 user I/Os in a 144-pin TQFP package with -3 (faster) speed grade. Built on a 0.42 µm CMOS SRAM-look-up-table architecture, the device operates from a 3.3 V core supply (VCCINT) and supports 2.5 V / 3.3 V / 5.0 V I/O via VCCIO banking. A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all customized via SRAM-based configuration memory. FPGAs sit within the broader Programmable Logic hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA, and serve as the lowest-cost / lowest-power option for glue logic, bus bridging, and low-density state-machine replacement compared with higher-density families. Key features 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, embedded IEEE 1149.1 JTAG boundary-scan support, and an in-system programmability (ISP) interface. The TQFP-144 footprint is shared across most FLEX 6000 densities via Altera's SameFrame pin-compatibility program, allowing designers to migrate designs across density points without PCB rework. Architecturally, the FLEX 6000 uses a continuous, hierarchical interconnect network (FastTrack) that delivers predictable timing across the device. The -3 speed grade targets internal frequencies up to 142.86 MHz, suitable for peripheral bus bridges, custom peripherals, and reconfigurable I/O expansion. The SRAM configuration cell requires a configuration device (e.g., EPC2) or JTAG download at every power-up. Typical applications include glue-logic integration in telecom line cards, industrial control boards, and legacy peripheral bus (PCI, ISA) bridge implementations, where its low cost and moderate density outperform mask-programmed gate arrays for low- to mid-volume production. The part is also used for prototyping where rapid design iteration is required. When designing with the EPF6016ATC144-3, ensure VCCINT is tied to 3.3 V and VCCIO is matched to the connected bus voltage; mismatched rails will damage I/O buffers. Also allocate a configuration PROM (EPC2, EPC4) or JTAG header for in-system programming - the device has no on-chip non-volatile memory.

EPF6016ATC144-3N - FLEX 6000 FPGA 16K Gates 1320 Cells TQFP-144
The Intel (formerly Altera) EPF6016ATC144-3N is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs) built on the OptiFLEX architecture, delivering approximately 16,000 gates and 1,320 logic elements in a 144-pin TQFP package. The device operates at a maximum internal frequency of 142.86 MHz, supports 117 user I/O pins, and is fabricated on a 0.42 micron CMOS process running at 3.3 V core supply. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that allows designers to implement custom digital logic circuits by configuring an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells after manufacture. FPGAs sit above CPLDs and gate arrays in the programmable logic hierarchy, offering higher logic density, finer-grained parallelism, and on-chip memory. The FLEX 6000 family specifically targets low-cost, high-volume designs that previously required fixed gate arrays, providing fast design iteration during prototyping. Key features of the EPF6016ATC144-3N include 1,320 logic elements (132 LABs/Logic Array Blocks), 117 user I/O pins, embedded SRAM configuration memory (SRAM-based, volatile configuration requiring external configuration device), in-system programmability via JTAG, and a speed grade of -3 indicating the commercial high-performance tier. The TQFP-144 package exposes all major interface signals including dedicated clock inputs, JTAG, and configuration pins. The OptiFLEX architecture minimizes die size through continuous, segmented routing resources interleaved with Logic Array Blocks. Each LAB contains ten logic elements with 4-input look-up tables (LUTs), a carry chain for arithmetic, and a cascade chain for wide fan-in functions. The device supports true dual-port and single-port embedded memory blocks for FIFO and register-file applications, plus dedicated I/O registers for high-speed source-synchronous interfaces. Typical applications for the EPF6016ATC144-3N include glue logic integration in telecommunications line cards, industrial control and factory automation controllers, low-cost replacement for fixed gate arrays in high-volume consumer products, bridge and protocol conversion between legacy peripherals, and educational or prototyping platforms where designers need a robust, mature, programmable logic fabric. The 117 available I/Os support a wide range of parallel bus widths and mixed-signal interface requirements. When designing with this device, note that the FLEX 6000 family uses SRAM configuration cells, so the bitstream must be reloaded from an external serial or parallel configuration PROM (such as the EPC2 or EPC8) on every power-up. Plan board layout to keep the 144-pin TQFP decoupling network within the inductance budget and to ensure JTAG chain access for in-system programming.

EPF6016ATC144-3S - FLEX 6000 FPGA, 132 LABs, 117 IOs | Intel
The Intel (formerly Altera) EPF6016ATC144-3S is a member of the FLEX 6000 family of Field Programmable Gate Arrays (FPGAs), delivering 16,000 typical gates (24,000 maximum system gates) in a 144-pin TQFP (Thin Quad Flat Pack) package. It provides 1,320 logic elements distributed across 132 Logic Array Blocks (LABs) with 117 user I/O pins, an internal frequency of 172 MHz, and is built on a 0.42 µm CMOS SRAM process with 5.0 V core voltage. A Field Programmable Gate Array (FPGA) is a type of integrated circuit that can be configured by the customer or designer after manufacturing, hence the term field-programmable. The FLEX 6000 family sits within Intel's programmable logic hierarchy between simpler Complex Programmable Logic Devices (CPLDs) and higher-density FPGAs such as the FLEX 10K and APEX families. FPGAs in general belong to the broader semiconductor taxonomy of Programmable Logic Devices (PLDs), which also include SPLDs and CPLDs. They are widely used for digital logic prototyping, glue logic, custom I/O interfacing, and pre-ASIC design verification where production volumes do not yet justify a mask-programmed gate array. The EPF6016ATC144-3S is specified as commercial grade with an operating temperature range of 0°C to 85°C and operates from a 5.0 V supply. The trailing S in the order code denotes a specific Altera/Intel ordering suffix (often indicating a particular shipment form or speed/packaging variant), while the -3 speed grade denotes the -3 performance bin within the FLEX 6000 family. The part supports in-system programmability via the IEEE 1149.1 (JTAG) boundary-scan interface and is configured via a serial configuration device. Typical applications for the EPF6016ATC144-3S include glue logic in telecom infrastructure, industrial control and factory automation I/O expansion, PCI bus interface bridging, custom peripheral controllers in embedded systems, and pre-ASIC prototyping where design teams need to validate RTL prior to tape-out. The 117 available user I/Os make the device well-suited to bridging legacy 5 V peripherals to modern ASICs or microprocessors. When designing with this part, ensure that all 5 V supply rails are properly decoupled with 0.1 µF ceramic capacitors placed within 5 mm of each VCC pin, and that JTAG chain integrity is verified before configuration. The device is now considered legacy/NRND: production of the FLEX 6000 family has largely ended, and Intel recommends migrating to Cyclone-series devices for new designs.
