EP1K10TC100-1 - ACEX 1K FPGA, 10K Gates, 100-TQFP | Altera
The Altera (Intel) EP1K10TC100-1 is a member of the ACEX 1K family of Field Programmable Gate Arrays (FPGAs), delivering 10,000 typical gates and 576 logic elements in a 100-pin Thin Quad Flat Pack (TQFP) package. The device operates from a 2.5V core supply, is fabricated on a 0.22 µm CMOS process, and supports system clock frequencies up to 250 MHz. The "-1" speed grade denotes the commercial-temperature ACEX 1K performance tier. An FPGA is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that allow the hardware function to be defined after manufacture. ACEX 1K belongs to the low-cost, 2.5V SRAM-lookup-table (LUT) based FPGA family from Altera and is one generation below the APEX and Cyclone product lines. Within the broader programmable logic taxonomy, ACEX 1K sits between classic CPLDs (smaller, non-volatile, lower density) and modern high-density FPGAs such as Cyclone and Stratix. Key features of the EP1K10TC100-1 include 12,288 bits of embedded dual-port SRAM, 72 logic array blocks (LABs), 66 user I/Os, JTAG-compliant boundary-scan test support (IEEE Std 1149.1), and embedded array blocks (EABs) that can be configured as memory or specialized logic functions such as multipliers and DSP primitives. The TQFP-100 footprint is a JEDEC-standard surface-mount package suitable for conventional reflow assembly. Typical applications include glue logic replacement, custom interface bridging (UART, SPI, I²C, parallel bus), low-density DSP, industrial control, telecommunications line cards, prototyping of ASIC functions, and educational platforms. Because ACEX 1K devices are SRAM-based, they must be configured at every power-up from an external configuration memory (EPCS or compatible), which is a key system-level design consideration. When designing with this FPGA, ensure that a 2.5V regulator with adequate decoupling is placed close to the VCCINT pins, that JTAG chain integrity is verified, and that I/O bank voltage compatibility (VCCIO) is matched to the connected peripherals.

EP1K10TC100-1N - ACEX-1K 10K Gates 250MHz FPGA | Intel
The Intel EP1K10TC100-1N is a member of the ACEX-1K family of Field-Programmable Gate Arrays (FPGAs), delivering 10,000 usable gates, 576 logic elements, and 12,288 bits of embedded RAM in a 100-pin TQFP surface-mount package. Built on a 0.22 µm CMOS SRAM process, the device operates from a 2.5 V core supply (range 2.375 V to 2.625 V) and is rated for commercial temperature operation from 0 °C to 70 °C with 66 user I/O pins available. According to the manufacturer datasheet, the -1N speed grade targets an internal frequency of approximately 180 MHz in the system. An FPGA (Field-Programmable Gate Array) is a class of programmable logic device (PLD) — within the broader taxonomy of integrated circuits, it sits below ASICs but above simple SPLDs/CPLDs in density. ACEX-1K devices integrate a sea of logic elements (LEs), embedded array blocks (EABs) that double as RAM/ROM, and a continuous routing network, allowing designers to implement arbitrary digital functions that are re-programmable in-system via SRAM configuration. ACEX-1K belongs to the Intel (formerly Altera) programmable logic family tree: PLD > CPLD/FPGA > SRAM-based FPGA > ACEX-1K. Key features include 72 Logic Array Blocks (LABs) arranged in a MegaLAB structure, 3 embedded array blocks of 4 Kbit each (12 Kbit total EAB) usable as 12,288 bits of RAM, JTAG (IEEE 1149.1) boundary-scan support, and multiVolt I/O compatible with 2.5 V/3.3 V/5 V mixed-voltage systems. The 100-pin TQFP package provides a low-profile 1 mm-height footprint with gull-wing leads, enabling placement on compact PCBs and standard surface-mount assembly lines. The -1N speed grade designates the slower commercial-tier silicon of the family, prioritizing cost over fMAX. Typical applications include glue-logic bridges in telecom line cards, industrial control and factory-automation backplanes, low-density data-path processing, custom interface conversion (e.g., UART/SPI/I2C bridging), and legacy peripheral replacement in systems that still specify ACEX-1K. Designers choose this part when an EEPROM- or flash-free volatile configuration stream is acceptable (an external configuration memory such as an EPC2 or EPCS is required at boot), and when pin count, I/O count, and logic density are matched. Designers should plan for an external configuration PROM (EPC2, EPCS1, or EPCS4 depending on bitstream size) because the ACEX-1K is SRAM-based and loses configuration at power-down. The 100-pin TQFP footprint provides convenient soldering and rework compared to BGA alternatives, but limits I/O expansion to 66 pins; designs exceeding that count require migration to the EP1K10QC208-3 or EP1K10FC256-3 package options in the same family. This page synthesizes distributor availability, drop-in alternatives from the same ACEX-1K family, and engineering design notes that complement the manufacturer's datasheet. Pricing reflects current distributor listings as of 2026-09-07.
EP1K10TC100-2 - 10K-Gate ACEX-1K FPGA, 576 LEs, TQFP-100 | Intel
The Intel EP1K10TC100-2 is a member of the ACEX-1K programmable logic family that delivers up to 10,000 usable gates in a 100-pin TQFP surface-mount package. It integrates 576 logic elements, 72 logic array blocks, 12,288 bits of embedded RAM, and 66 user I/O pins on a 2.5V CMOS fabric built on a 0.22 μm process node. An FPGA (Field Programmable Gate Array) is a semiconductor IC containing an array of configurable logic blocks (LBs), programmable interconnect, and I/O cells that can be re-wired by the user to implement arbitrary digital circuits. Within the wider taxonomy, FPGAs sit above CPLDs and below ASICs in terms of integration density, and they belong to the broader category of programmable logic devices (PLDs). ACEX-1K parts are positioned at the low-density, low-cost end of the FPGA spectrum, intended for glue logic, bus bridging, and small state-machine applications where an ASIC is uneconomical. Key features include a 0.5 ns pin-to-pin logic delay, dual-port embedded memory, dedicated carry chains for fast arithmetic, JTAG-compliant IEEE 1149.1 boundary-scan, in-system programmability via the serial configuration interface, and support for multiple I/O standards including LVTTL, LVCMOS, and PCI. The device is rated for commercial 0 °C to 70 °C ambient operation and runs from a 2.375 V to 2.625 V core supply. The EP1K10TC100-2 uses a SRAM-based look-up-table (LUT) architecture with continuous, row-and-column interconnect. Configuration data is loaded from an external serial PROM or via JTAG; the design is volatile and must be re-loaded on every power-up, which differentiates ACEX-1K from one-time-programmable (OTP) anti-fuse families. Typical applications include industrial control glue logic, communications protocol bridging, low-volume custom peripherals, and legacy retrofit boards where a discontinued discrete-logic design must be consolidated into a single programmable device. The wide 2.5 V tolerance band simplifies multi-voltage design. When designing with this part, note that the ACEX-1K family has been EOL'd by Altera/Intel; design engineers should verify long-term availability or migrate to a Cyclone equivalent for new designs. Always include a configuration PROM and follow the recommended decoupling scheme (0.1 μF + bulk) on every VCCINT and VCCIO pin pair. This page consolidates distributor pricing, same-brand drop-in alternatives from the ACEX-1K family, and practical design notes not present in the original datasheet PDF.

Built on a 0.22 um CMOS process and powered from a 2.5 V core supply, the device delivers up to 200 MHz system performance and provides 66 user I/O pins for moderate-density glue-logic, control, and signal-processing designs. The "-2N" speed grade identifies a commercial-temperature part with the second-fastest bin in the family, while the "TC100" suffix denotes the TQFP-100 package and lead-free finish. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the volume production economics of a standard IC with the design flexibility of custom logic. ACEX-1K belongs to the embedded-array branch of the FPGA taxonomy (FPGA -> PLD -> programmable logic -> digital IC -> semiconductor), integrating a lookup-table-based logic fabric with embedded array blocks (EABs) that can be configured as RAM, ROM, or multiplier primitives. This makes the EP1K10 well-suited to system-on-a-programmable-chip (SOPC) integration where the designer needs both glue logic and small blocks of memory or DSP. Key features of the EP1K10TC100-2N include 576 logic cells distributed across 72 logic array blocks (LABs), 12,288 bits of embedded memory, in-system programmability via the IEEE 1149.1 (JTAG) interface, and four-phase on-chip PLL support for clock management. The device supports configuration through passive serial, active serial (EPC2/EPC16), or JTAG modes, and is supported by the Altera Quartus II and MAX+PLUS II development environments. The -2 speed grade provides approximately 0.7 ns gate-delay typical timing at 25 C ambient. Architecturally, ACEX-1K cells consist of a 4-input look-up table (LUT), a programmable register, and carry-chain logic that feeds the next cell, enabling efficient arithmetic and counter operations. The 100-pin TQFP footprint uses a thin (1.0 mm) body with gull-wing leads on a 0.5 mm pitch, making it hand-solderable and compatible with low-cost two-layer PCB assembly flows. Multi-voltage I/O banks allow 1.8 V, 2.5 V, 3.3 V, and 5 V interfacing without external level shifters. Typical applications include industrial control and glue logic, low-density communication bridges, PCI/ISA bus interfaces, custom register-decoder and state-machine designs, educational FPGA platforms, and legacy design maintenance where the original ACEX-1K footprint must be preserved. Designers porting older ACEX-1K designs can drop the EP1K10TC100-2N directly onto an existing PCB without layout changes. When designing with this part, observe the IOREF pin configuration for mixed-voltage operation, ensure the JTAG chain includes appropriate TCK pull-down and TDI/TMS pull-up resistors, and follow Altera's power-up sequencing recommendations for the 2.5 V VCCINT and 3.3 V VCCIO rails. Quartus II 13.0 or earlier is the last officially supported toolchain, which is an important consideration for new design starts. This page synthesizes distributor pricing, drop-in same-package alternatives within the ACEX-1K family, and practical design notes that go beyond what is printed in the original datasheet.

Operating from a 2.375 V to 2.625 V core supply, the device is built on a 0.18 µm SRAM-based lookup-table architecture and is factory-marked Obsolete, with remaining inventory supplied through authorized distributors and the secondary market. A Field-Programmable Gate Array (FPGA) is a reconfigurable integrated circuit that lets designers implement custom digital logic, state machines, datapaths, and interface bridges after PCB fabrication. FPGAs occupy the broad hierarchy of programmable logic devices (PLD) -> CPLD/FPGA -> programmable logic -> digital semiconductor. The ACEX-1K series, introduced by Altera (later acquired by Intel), targets cost-sensitive glue-logic, bus-bridging, and low-density state-machine applications where ASIC NRE is unjustified. Key features of the EP1K10TC100-2NGZ include 72 logic array blocks (LABs), 12,288 bits of embedded SRAM distributed across the fabric, support for Altera's Quartus II design suite, in-system programmability via JTAG, and a commercial 0 °C to 70 °C operating temperature range. The 100-TQFP footprint allows hand-solderable prototyping on standard 0.5 mm-pitch land patterns, eliminating the need for BGA reflow equipment in small-volume builds. Typical applications include industrial control interfaces, legacy parallel-bus bridges (PCI, ISA), telecommunications glue logic, instrumentation front-end controllers, and education platforms where TQFP packages simplify lab rework. The EP1K10TC100-2NGZ is pin-compatible with other 100-TQFP ACEX-1K members, letting designers migrate between speed grades (-2 vs -3) and density options (10K vs 30K) without re-spinning the PCB. When designing with this device, verify that your Quartus II tool version still supports the ACEX-1K device family, and budget for legacy support contracts or migration to Cyclone-series devices for new designs. Always confirm the supply-voltage tolerance against the host 2.5 V rail, and respect the 66-user-I/O limit when assigning pin functions.

Typical applications include industrial control glue logic, low-density communication bridge devices, PCI bus interface controllers, and legacy embedded system upgrades. The 100-pin TQFP package supports conventional SMT assembly on 2-layer or 4-layer PCBs without requiring BGA-class PCB fabrication capabilities. Engineers commonly deploy this device in cost-sensitive designs where modern Cyclone or MAX II FPGAs exceed the BOM budget. Designers should leverage Altera Quartus II (legacy versions MAX+PLUS II or Quartus II 7.2 and earlier) for synthesis, place-and-route, and programming file generation. Note that ACEX-1K is no longer in active production - new designs should evaluate Cyclone II/III/IV as modern replacements when supply allows.

The 66 user I/Os and 12 Kb of embedded memory are well matched to glue-logic bridges, custom peripheral controllers, and small DSP front-ends. When designing with this part, engineers should note that the ACEX-1K family has been superseded by Cyclone-series FPGAs in modern designs. The Quartus design tool (versions up to 13.0) supports this device, but new development should consider Cyclone II/III for active lifecycle status and improved power efficiency. This page synthesizes distributor pricing, drop-in alternatives within the ACEX-1K family, and practical design notes not consolidated in the manufacturer datasheet alone.
EP1K10TC144-1 - ACEX-1K FPGA, 10K Gates, 144-LQFP | Intel / Altera
The Intel (formerly Altera) EP1K10TC144-1 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs) featuring 10,000 typical gates, 576 logic elements (LEs), and 12,288 RAM bits, housed in a 144-pin LQFP (TQFP) package with 92 user I/Os. It is built on a 0.22 µm EEPROM process with a 2.5 V core supply, supporting commercial-grade operation. An FPGA (Field Programmable Gate Array) 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 customized after manufacturing. FPGAs sit at the top of the programmable logic hierarchy, above CPLDs and SPLDs, and are widely used for glue logic, signal processing, bus interfacing, and prototyping where ASIC NRE costs cannot be justified. The ACEX-1K family is an early-2000s SRAM/EEPROM-based architecture from Altera, designed for low-cost system-on-a-programmable-chip (SOPC) integration. Key features of the EP1K10TC144-1 include 72 logic array blocks (LABs), an embedded array block (EAB) for efficient memory and specialized logic functions such as multipliers and DSP primitives, dual-port RAM support, and 12,288 bits of embedded memory.

An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the high density of gate arrays with the design flexibility of programmable logic. FPGAs sit in the hierarchy: FPGA -> programmable logic -> ASIC alternative -> digital integrated circuit. ACEX-1K devices are low-cost, SRAM-based FPGAs targeting high-volume glue-logic, bus-interface, and DSP co-processing applications where mid-range logic density is required without the cost of higher-end FPGA families. Key features of the EP1K10TC144-1N include a maximum internal operating frequency of 250 MHz, embedded array blocks (EABs) implementing dual-port RAM, ROM, or FIFO functions, and a MultiVolt I/O interface supporting 2.5 V and 3.3 V signalling. The device supports in-system programmability via configuration schemes including passive serial, passive parallel synchronous, and JTAG. Per-device power consumption is typically 0.5 mA quiescent current plus dynamic current dependent on toggle rate and logic utilization. Architecturally the EP1K10TC144-1N combines Logic Array Blocks (LABs) and Embedded Array Blocks (EABs). LABs implement general-purpose combinational and sequential logic while each EAB provides 4 Kbits of RAM that can be configured for synchronous single-port or dual-port memory. Fine-grained look-up tables (LUTs) drive efficient state-machine and arithmetic implementations, and dedicated carry chains support high-speed adders. Typical applications include industrial control interfaces, legacy bus-bridging glue logic, communication backplane controllers, low-cost DSP pre-processing, and educational/development platforms. The 144-pin TQFP footprint is well suited to through-hole-friendly prototyping PCBs while still allowing surface-mount assembly. When designing with the EP1K10TC144-1N, verify the configuration mode (typically passive serial for ACEX-1K) and EPC configuration memory compatibility. Use the Quartus II design software (legacy) or Max+Plus II to capture schematics and verify timing closure at 250 MHz worst-case.

EP1K10TC144-2 - ACEX-1K FPGA, 10K Gates, 144-LQFP | Altera
The Altera (now Intel) EP1K10TC144-2 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGA) delivering 10,000 typical gates, 576 logic elements (LEs) and 12,288 RAM bits in a 144-pin LQFP (TQFP) package. The device integrates an enhanced embedded array for implementing megafunctions such as efficient memory and specialized logic functions, with dual-port RAM capability. It is fabricated on a 2.5 V core process and is offered in a commercial temperature grade. An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that can be re-programmed after manufacture to implement arbitrary digital logic. FPGAs sit at the top of the programmable logic hierarchy between CPLDs (less complex, non-volatile, lower density) and ASICs (highest density, fixed function). The ACEX-1K family was Altera's first SRAM-based, look-up-table (LUT) FPGA family, designed as a low-cost System-On-a-Programmable-Chip (SOPC) integration platform bridging CPLD simplicity with FPGA density. Key features include 92 user I/O pins, dual-port embedded array blocks (EABs), in-system programmability via JTAG, and support for multiple I/O standards including LVTTL, LVCMOS and PCI. The device operates from a 2.5 V core supply with 3.3 V tolerant I/O options, and the 144-LQFP (also written TQFP-144) footprint is a JEDEC-standard surface-mount package with 1.0 mm pitch. The ACEX-1K architecture uses a fine-grained LUT-based logic element feeding into a hierarchical routing fabric with embedded array blocks (EABs) providing dual-port RAM and ROM. Per the Altera ACEX 1K Device Family datasheet (2.5V), each EAB can be configured from 256x8 to 4096x1 of true dual-port memory, enabling wide datapath and FIFO implementations without external memory. Configuration is volatile SRAM-based, so an external configuration memory (typically EPC2 or EPCQ) is required at power-up. Typical applications include glue logic replacement, bridge and protocol conversion (e.g., PCI to local bus), low-volume ASIC prototyping, industrial control and instrumentation front-ends, and embedded control DSP co-processing. The 144-LQFP package is hand-solderable and well suited to prototype runs and low-to-mid volume production. When designing with this part, note that the configuration memory (EPC2/EPCQ) must be specified separately and the JTAG chain length must be observed; because ACEX-1K is an older family, new designs should evaluate Cyclone IV/V or MAX 10 instead. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
EP1K10TC144-2N - 10K Gate ACEX-1K FPGA, 92 I/O, TQFP-144 | Intel / Altera

Configuration is handled by a serial PROM, controller, or JTAG port, and the device operates from a single 2.5 V core supply with separate VCCIO rails for the I/O banks. Typical applications include glue logic replacement on legacy PC/104 and VME boards, custom state-machine controllers in industrial automation equipment, low-density DSP pre/post-processing pipelines, and peripheral bridging (UART, I²C, SPI) in networking line cards. The 92 available I/O pins comfortably drive 8-bit or 16-bit parallel buses plus control signals, while the 12 Kbit embedded RAM supports small FIFO and lookup-table implementations without external memory. Designers should pay particular attention to I/O bank voltage constraints: the EP1K10TC144-2N supports 2.5 V and 3.3 V on the same die, but mixing 5 V inputs requires external resistor dividers since the device has no 5 V-tolerant I/O. Quartus II design software (version 13.0 or earlier is the last release supporting ACEX-1K) is required for synthesis, place-and-route, and bitstream generation.
EP1K10TC144-3 - 10K Gate ACEX-1K FPGA 144-LQFP | Intel / Altera
The Intel / Altera EP1K10TC144-3 is a member of the ACEX-1K family of FPGAs featuring 10,000 typical gates, 576 logic elements (LEs), and 12,288 RAM bits in a 144-pin LQFP package with 92 user I/O pins. Built on a 2.5V, 0.22 µm CMOS SRAM-lookup-table (LUT) process, the device integrates an embedded array of dual-port RAM blocks with a logic array to deliver megafunction-level integration for low-cost system-on-a-programmable-chip (SOPC) designs. The "-3" speed grade targets commercial timing closure at up to 200 MHz internal operation. A Field-Programmable Gate Array (FPGA) is a reconfigurable digital IC whose logic function is defined by user-supplied configuration bitstreams stored in on-chip SRAM. The ACEX-1K family belongs to the broader taxonomy of programmable logic devices (PLD), which spans simple PLDs, complex PLDs (CPLD), and FPGAs. Within Intel's / Altera's portfolio, the ACEX-1K sits between the older FLEX family and the Cyclone series, sharing the LUT-based fabric of modern FPGAs while keeping a low unit cost that made it popular in glue-logic, bus-interface, and low-volume telecom designs of the early 2000s. Key architectural features include four embedded array blocks (EABs) implementing dual-port RAM up to 4 Kbits each, dedicated carry chains for fast arithmetic, and JTAG-based in-system programmability through the IEEE 1149.1 boundary-scan interface. The LUT-based logic elements offer fast combinatorial paths, and the device is supported by the Quartus II design suite (legacy) for synthesis, place-and-route, and timing analysis. Note that ACEX-1K devices are no longer recommended for new designs. Typical applications include communications interface bridging, peripheral expansion in embedded motherboards, glue logic between microprocessors and memory buses, low-volume industrial control, and legacy design maintenance. The 92 available I/Os and 12 Kbits of block RAM make it well suited to bus-protocol conversion and small FIFO buffering tasks. When designing with this part, ensure the 2.5V VCCINT and 3.3V-tolerant VCCIO rails are decoupled per the Altera ACEX-1K handbook, and that configuration is supplied through a stable EPC or microcontroller loader because the SRAM fabric loses configuration on power-down. Programming files are generated with Quartus II software. This page synthesizes distributor pricing, drop-in same-package alternatives, and design notes not found in the manufacturer datasheet.

The Intel (formerly Altera) EP1K10TC144-3N is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs) featuring 10,000 typical gates, 576 logic elements, and 12,288 RAM bits in a 144-pin LQFP (TQFP) package. It is built on a 0.22 um CMOS process with a 2.5 V core supply and supports -1 speed-grade PCI compliance at 5.0 V I/O. The device is offered in the -3N speed grade, indicating enhanced timing performance versus the -1 and -2 grades within the same family. An FPGA (Field Programmable Gate Array) is a programmable logic device that allows designers to implement arbitrary digital logic functions through a sea of configurable logic blocks (LBs), embedded memory blocks, and programmable interconnect. The ACEX-1K family sits in the hierarchy as an SRAM-based, look-up-table (LUT) FPGA below the more complex APEX and later Cyclone families. FPGAs of this class are widely used in glue logic, bus interfacing, and low-to-medium density state-machine implementations where mask-programmed gate arrays would otherwise be uneconomical. Key features of the EP1K10TC144-3N include 92 user I/O pins (out of 144 package pins), built-in dual-port RAM capability, and integrated Joint Test Action Group (JTAG) boundary-scan test circuitry compliant with IEEE Std. 1149.1-1990. The -3N speed grade corresponds to faster internal timing than the -1N and -2N grades of the same die, making it suitable for throughput-sensitive control logic. The embedded array block (EAB) architecture supports megafunctions such as efficient memory, multipliers, and specialized peripheral logic. Typical applications include PCI bus interface bridging, telecommunications line-card glue logic, industrial control state machines, and legacy replacement for discrete TTL/CMOS logic. The 144-LQFP package allows hand-repairable assembly and standard surface-mount manufacturing flows. The 'N' suffix typically indicates an industrial temperature grade or lead-free / Pb-free assembly, which engineers should confirm against the manufacturer datasheet for the exact revision. When designing with the EP1K10TC144-3N, ensure the Quartus II or MAX+PLUS II toolchain is configured for the ACEX-1K family and that the I/O voltage bank assignments match the system logic. The -3N speed grade may require additional timing closure effort compared to the slower grades. This page synthesizes distributor availability, same-family drop-in alternatives (such as the -1N and -2N speed grades), and design considerations not consolidated in any single manufacturer document.
EP1K10TC144-3N - ACEX 1K FPGA, 10K Gates, 144-TQFP | Altera
The Altera EP1K10TC144-3N is a member of the ACEX 1K programmable logic device family built on a 2.5 V CMOS process with 10,000 typical gates (equivalent to 56,000 logic gates in normalized metrics), delivering an 80 MHz system performance and packaged in a 144-pin TQFP (TQ144). The part features 576 logic elements distributed across 72 logic array blocks (LABs), 12,288 bits of embedded array block (EAB) RAM organized as dual-port memory, and 92 user I/Os that meet PCI Local Bus Specification Revision 2.2 for 5.0 V operation. A Field Programmable Gate Array (FPGA) is a programmable logic device that lets engineers implement arbitrary digital logic by configuring an array of configurable logic blocks (CLBs), embedded memory blocks, and routing resources via SRAM-based configuration cells. FPGAs sit at the top of the programmable logic hierarchy: PLD -> CPLD -> FPGA -> SoC FPGA. The ACEX 1K family occupies the cost-optimized SOPC (system-on-a-programmable-chip) tier of legacy Altera FPGAs, providing dual-port RAM, megafunction support via the embedded array, and JTAG IEEE Std. 1149.1 boundary-scan test (BST). Key differentiating features include a dedicated EAB architecture for efficient memory and specialized logic functions, dual-port RAM for FIFO/buffer designs, built-in JTAG boundary-scan (IEEE 1149.1) that consumes no additional device logic, and -3 speed grade timing with 80 MHz performance. The TQFP-144 thermal envelope (plastic quad flatpack with exposed lead-frame pads) supports fanless industrial designs at moderate toggle rates, and the 2.5 V core with PCI-compliant I/Os simplifies 3.3 V/5 V mixed-rail board designs. The ACEX 1K architecture couples four-input look-up tables (LUTs) per logic element with a programmable flipflop, dedicated carry and cascade chains for fast arithmetic, and a local interconnect within each LAB that lets eight LEs implement medium-sized blocks such as 8-bit counters or address decoders without consuming global routing. Configuration is SRAM-based and reloadable, allowing in-system updates. Typical applications span glue logic, bus bridges, custom peripheral controllers, and low-cost glue ASIC replacement in industrial control, telecom line cards, test and measurement front-ends, and PCI peripherals. Designers favor this family when 10K-gate density, embedded dual-port RAM, and 5V-tolerant I/Os matter more than absolute state-of-the-art logic capacity. Design consideration: the 2.5 V core requires careful power sequencing versus 3.3 V I/O rails, and the SRAM configuration memory means an external configuration PROM (EPCS or compatible) is mandatory for volatile-free boot. The -3 speed grade is the fastest commercially available bin for this die.

EP1K10TI100-2 - 10K Gates ACEX-1K FPGA 66 I/O TQFP-100 | Intel / Altera
The Intel / Altera EP1K10TI100-2 is a member of the ACEX-1K family of FPGAs (Field Programmable Gate Arrays), built on a 0.22 µm CMOS SRAM process and offering 10,000 typical gates, 576 logic elements, and 12,288 RAM bits in a 100-pin TQFP package with 66 user I/Os. The "I" suffix designates the industrial temperature grade (-40 °C to +85 °C) and the "-2" speed grade corresponds to a faster performance bin, supporting internal toggle frequencies up to 200 MHz. An FPGA (Field Programmable Gate Array) is a programmable logic device containing an array of configurable logic blocks (CLBs), embedded memory, and programmable interconnect that the designer can configure after manufacturing to implement any digital logic function. FPGAs sit hierarchically between fixed-function ASICs (Application Specific Integrated Circuits) and CPLDs (Complex Programmable Logic Devices), offering higher logic density and richer I/O features than CPLDs but lower performance-per-watt and higher unit cost than volume-production ASICs. The ACEX-1K family was Altera's first FPGA family to embed dedicated dual-port RAM (EAB) blocks alongside the logic fabric. Key features of the EP1K10TI100-2 include 72 LABs (Logic Array Blocks) each containing 8 logic elements, 3 embedded array blocks (EABs) providing 12,288 total RAM bits, four low-skew global clock networks, multi-voltage I/O support (2.5 V core with 3.3 V / 5 V tolerant I/O on selected banks), and in-system programmability via the IEEE 1149.1 JTAG interface or the Altera EPC serial configuration device. The device architecture combines an SRAM-based look-up table (LUT) logic fabric with fast carry chains for arithmetic, distributed inter-LAB routing, and dedicated phase-locked loops on higher-density ACEX-1K members (the EP1K10 is the smallest member and does not include PLLs). It targets glue-logic, bus-bridging, and state-machine consolidation designs where the 10K-gate capacity is sufficient. Typical applications include industrial control interfaces, communications glue logic, legacy 8051/microcontroller bus expansion, I/O buffering and level translation, custom state machines, and low-volume prototyping where the design may later migrate to a structured ASIC. When designing with this part, note that the 100-pin TQFP limits I/O count to 66 and the absence of on-chip PLLs constrains clock management; designers needing more I/O or clock synthesis should migrate to the EP1K30 / EP1K100 in TQFP-144 or larger packages. Power estimation requires Altera's PowerPlay tool because static and dynamic power depend heavily on utilization and toggle rate. This page synthesizes distributor pricing, drop-in same-package alternatives within the ACEX-1K family, and design notes that complement the manufacturer datasheet.

The -2 speed grade offers a balance between timing closure and cost; the N suffix indicates lead-free / Pb-free assembly. Designers can implement megafunctions including dual-port RAM, FIFO buffers, DSP blocks, and standard interfaces, all backed by Altera's Quartus II design suite. Technically, the EP1K10TI100-2N uses a continuous, segmented routing architecture with every LAB containing 8 LEs, each LE carrying a 4-input LUT, programmable register, carry chain, and cascade chain. The embedded array blocks (EABs) provide true dual-port RAM up to 4 Kbits each, configurable to various widths. The device operates from a 2.5V core with multi-voltage I/O support through banked VCCIO rails, typically 3.3V or 2.5V. Typical applications include glue logic in industrial control, communications protocol bridges, low-volume ASIC replacement, factory automation controllers, wireless baseband glue, and medical instrumentation. Designers migrating to newer Cyclone or MAX families should note that ACEX-1K is now legacy; the recommended modern replacement is the Cyclone IV family in compatible footprints. When designing with this device, ensure your Quartus II version supports ACEX-1K (legacy device support) and budget for I/O bank voltage compatibility if mixing 3.3V and 2.5V peripherals. The 100-TQFP package simplifies PCB layout with all-pin-perimeter access, but pay close attention to trace length matching for clock-distribution paths.

Per the verified distributor data, this part is fabricated on a 0.22 µm process, operates from a 2.5 V core supply, and supports up to 92 user I/O pins with a maximum clock frequency of 200 MHz (the same source quotes a lower 37.5 MHz figure on a separate listing, indicating datasheet variation; the 200 MHz figure is used as the headline). The "I" in the suffix denotes the Industrial temperature grade (-40 °C to +85 °C), and the "-2" speed grade positions this device in Altera's mid-range performance tier for the ACEX 1K family. An FPGA (Field Programmable Gate Array) is a programmable logic device that lets designers implement arbitrary digital logic through a configurable array of logic elements, embedded memory blocks, and routing interconnects. FPGAs sit in the broader category of programmable logic devices (PLDs), above simple CPLDs and below structured ASICs in terms of integration density. The ACEX 1K family targets low-cost, high-volume applications by combining look-up-table based logic with embedded array blocks (EABs) that double as dual-port RAM or ROM, enabling single-chip system-on-a-programmable-chip (SOPC) integration. Key features include 10K equivalent gates, 576 logic cells, 12 Kbits of embedded memory via embedded array blocks, in-system programmability through the IEEE 1149.1 JTAG interface, and a 2.5 V core with multi-voltage I/O support. The TQFP-144 package offers a 0.5 mm terminal pitch on a 22 mm × 22 mm body, suitable for socketed or hand-solderable designs in volume production.

The EP1K10TI144-2 is built on a SRAM-based configuration cell architecture, requiring a configuration device such as the Altera EPC2 or EPC8 for stand-alone operation. The embedded array blocks (EABs) support dual-port RAM, ROM, FIFO, and multiplier functions, making the device suitable for DSP pipelines and small state machines. Configuration is loaded serially or via JTAG, and the device supports multi-device configuration chains for larger systems. Typical applications include DSL modem glue logic, low-cost Ethernet switches, industrial control interfaces, glue logic for embedded processors, and small-volume prototyping where mask-programmed ASICs are uneconomical. Per the datasheet summary, the 2.5 V core enables low-power operation while the SameFrame pin-out across the ACEX 1K family supports migration to larger EP1K30 or EP1K50 devices on compatible footprints where available. When designing with the EP1K10TI144-2, plan the configuration memory interface early: the SRAM-based cells require a non-volatile configuration device on every board. Plan I/O bank voltage rails carefully, since each bank supports a single VCCIO level. Verify JTAG chain order before board bring-up to avoid configuration contention with other devices on the scan chain. This page consolidates distributor availability, drop-in same-package alternatives, and practical design notes beyond what the manufacturer datasheet provides in isolation.

Key features include 1,728 logic elements, 24,576 bits of embedded SRAM, 171 maximum user I/O, in-system programmability through an IEEE 1149.1 JTAG interface, and a dedicated multiplier-friendly architecture for DSP-style datapaths. The 256-ball FBGA package provides dense interconnect access while supporting surface-mount reflow assembly. Core logic operates from a 2.5 V supply with separate VCCIO banks for I/O flexibility (2.5 V/3.3 V LVCMOS/LVTTL support is typical for the family). Architecturally, the device combines Look-Up Table (LUT)-based logic elements with Embedded Array Blocks (EABs) that can be configured as RAM or ROM. The ACEX-1K family is fabricated on a 0.22 µm four-layer metal CMOS SRAM process, meaning configuration data must be loaded from an external PROM or flash at every power-up. Maximum internal operating frequency is typically specified up to 250 MHz depending on speed grade and routing. Typical applications include industrial control glue logic, telecom interface adaptation, custom bus bridges, low-volume ASIC replacement, and prototyping platforms for larger Altera/Intel FPGA designs. The high I/O count (171) makes the 256-FBGA well-suited for designs with multiple parallel interfaces. When designing with this part, designers should plan for an external configuration memory (EPC configuration device), respect JTAG chain isolation, and verify signal integrity on the 256-ball FBGA escape. The EP1K30 is now considered mature/legacy silicon - new designs should evaluate Cyclone or MAX series for active longevity.

Typical applications include glue logic in telecom line cards, industrial control interfaces, low-cost communication bridges, and legacy PCI/ISA bus controllers. The 256-BGA FineLine footprint also makes it suitable for space-constrained designs where surface-mount ball-grid assembly is preferred over QFP. When designing with EP1K30FC256-2, ensure the configuration plan accounts for SRAM-based volatility (external serial configuration PROM required at boot) and verify MultiVolt I/O bank compatibility with connected peripherals. The -2 speed grade should be evaluated against the -3 (slower) and -1 (faster) variants for timing margin.

Typical applications include networking and communications equipment, industrial control panels, test and measurement systems, consumer audio/video bridging, and IoT sensor aggregation. The device is chosen when an engineer needs a moderate amount of programmable logic, many general-purpose I/O pins, and predictable low-cost performance on a 2.5 V design. A key design consideration is that the FPGA configuration is volatile: the bitstream must be loaded from external memory or a download cable after every power-up. Designers must also add adequate power-supply decoupling and carefully manage the FPGA configuration pins such as DCLK and CONF_DONE during board bring-up. This page synthesizes distributor pricing, ACEX 1K drop-in alternatives, practical design notes, and procurement guidance that are not normally listed together on a single manufacturer datasheet page. It is intended for engineers evaluating the EP1K30FC256-2N for legacy maintenance, replacement, or cost-sensitive programmable logic designs.
EP1K30FC256-3 - ACEX 1K FPGA 30K Gates | Altera
The Altera EP1K30FC256-3 is an ACEX 1K field-programmable gate array (FPGA) with 1,728 logic elements, 24,576 RAM bits, 30K typical gates and 171 user I/Os, housed in a 256-ball FineLine BGA (FBGA) package.\n\nAn FPGA is an integrated circuit that can be programmed after manufacturing to implement arbitrary digital logic. The ACEX 1K family belongs to the programmable-logic device hierarchy that includes FPGA subfamilies, SRAM-based programmable devices, and large-scale digital logic. The EP1K30FC256-3 sits below large FPGAs such as APEX or Cyclone families but above small CPLDs, making it suitable for medium-density glue logic, bus interfacing, and protocol conversion tasks.\n\nKey specifications from the available distributor and datasheet-index data include a 2.5V CMOS core, 2.375V to 2.625V supply range, 216 LABs, 171 user I/Os, 24,576 bits of embedded RAM, and 30K typical gates. The package is a 256-ball FineLine BGA, approximately 17 x 17 mm with 1.0 mm ball pitch. The speed grade is -3, and the same FC256 footprint is available in faster -2 and -1 speed bins.\n\nBecause the ACEX 1K device is SRAM-based programmable logic, configuration data must be loaded at power-up from an external boot source or configuration device. The EP1K30FC256-3 provides enough logic and I/O for moderate-density designs such as memory controllers, protocol bridges, industrial control state machines, and display timing generators, while its low 2.5V core voltage helps manage power in compact systems.\n\nTypical applications include legacy communications equipment, mature industrial control boards, test and measurement instruments, and FPGA education/prototyping platforms. The 256-ball package provides 171 user I/Os, allowing parallel buses and control signals to be brought out without complex multiplexing. Designers often select this device when board space is limited and a single programmable component must replace multiple discrete logic devices.\n\nWhen designing with this device, keep the core supply within the 2.375V to 2.625V range and place decoupling capacitors close to the FPGA supply balls. Since this is a legacy family, confirm current availability and configuration-device support before starting a new board design.\n\nThis page compiles verified distributor listings, datasheet download links, same-footprint speed-grade alternatives, and practical design notes so engineers can evaluate the EP1K30FC256-3 without leaving the page.
EP1K30FC256-3AA - 30K Gate ACEX-1K FPGA, 256-FBGA | Altera
The Altera EP1K30FC256-3AA is a member of the ACEX-1K family of Field-Programmable Gate Array (FPGA) devices, integrating 30,000 typical gates, 1,728 logic elements, and 24,576 bits of embedded array block (EAB) RAM in a 256-ball FineLine BGA package. It provides 171 user I/O pins and operates across industrial temperature ranges, making it suitable for high-volume glue-logic, interface bridging, and custom datapath applications. An FPGA (Field-Programmable Gate Array) is a reconfigurable semiconductor device that lets engineers implement arbitrary digital logic in silicon after fabrication. Architecturally, an FPGA is a power-management-adjacent integrated circuit - it sits alongside voltage regulators, clock generators, and memory in the broader digital system hierarchy. The ACEX-1K family uses a lookup-table (LUT) based logic fabric with embedded SRAM blocks (EABs), providing a balance of logic density and on-chip memory for datapath, state-machine, and FIFO designs. Key features of the EP1K30FC256-3AA include a speed grade of -3 (fastest in the family), 5V-tolerant I/O on selected banks, in-system programmability via the IEEE 1149.1 JTAG interface, and support for the MAX+PLUS II and Quartus development flows. The device operates from a 2.5V core supply with separate VCCIO rails for I/O bank compatibility with 3.3V, 2.5V, or 1.8V signaling. Typical applications include telecommunications line cards, industrial control and instrumentation, glue-logic replacement for ASICs, low-to-medium density data-path acceleration, and legacy system upgrades. The 256-FBGA package provides fine-pitch (1.0 mm) routing with SameFrame pin-out migration paths across the ACEX-1K family. The part is mature and in active distribution, often used to support long-lifecycle industrial designs. When designing with this device, ensure JTAG chain integrity for in-field updates, validate I/O bank voltage compatibility with adjacent logic, and use Quartus or MAX+PLUS II for synthesis. Note that ACEX-1K is a mature family - confirm long-term availability with your distributor before committing to new designs.
