EP1K50TC144-2 Présentation

The Intel (formerly Altera) EP1K50TC144-2 is a member of the ACEX-1K family of 2.5 V field-programmable gate arrays with 50,000 typical gates, 2,880 logic elements, and 40,960 system gates, housed in a 144-pin TQFP (TC144) package. The suffix "-2" denotes a commercial speed grade suitable for cost-sensitive, non-timing-critical designs; the "TC" envelope code indicates a thin quad flat pack (TQFP) surface-mount body. Per the verified distributor data, the device exposes 102 user I/O pins organized as 360 logic array blocks (LABs) with embedded array blocks (EABs) for on-chip memory and dedicated logic functions.

An FPGA (Field-Programmable Gate Array) is a class of programmable logic device (PLD) that allows engineers to implement arbitrary digital logic, glue logic, state machines, bus interfaces, and soft processor cores after PCB fabrication. Within the broader semiconductor hierarchy, FPGAs sit above ASICs and microcontrollers in design flexibility but below them in per-unit cost and static power. The ACEX-1K family belongs to Altera's low-cost SRAM-based FPGA lineage, predating the Cyclone series and offering embedded dual-port RAM blocks, a 2.5 V core supply, and a 0.22 µm CMOS process that targets glue logic, communication bridges, and low-volume ASIC prototyping.

Key features of the EP1K50TC144-2 include 49,152 bits of embedded RAM distributed across EABs, multi-voltage I/O support via selectable bank standards, in-system programmability through the IEEE 1149.1 JTAG interface and Altera EPC configuration devices, and a maximum internal toggle frequency around 200 MHz. The 144-pin TQFP body provides manageable board-level assembly using conventional SMT lines without requiring fine-pitch BGA reballing, easing low-to-medium volume production and bench prototyping.

The architecture combines a continuous interconnect network with LAB-based logic, EAB-based memory, and dedicated I/O element (IOE) cells with slew-rate and drive-strength control. Each LAB contains ten logic elements (LEs), and each LE embeds a 4-input LUT plus a programmable register, enabling efficient mapping of wide combinational paths and pipelined datapaths. The 2.5 V core and I/O bank supplies allow interfacing with 3.3 V peripherals through level-shifting I/O standards.

Typical applications include industrial control and glue logic replacement, communication protocol bridges (UART, SPI, I2C), low-volume ASIC prototyping, educational and lab development boards, parallel-to-serial converters, and simple peripheral controllers. Designers also target the EP1K50TC144-2 for legacy system upgrades where existing ACEX-1K designs are being re-spun or migrated to a long-lifecycle pin-compatible footprint.

When designing with this part, note that the ACEX-1K family is mature, and Intel has transitioned new designs to the Cyclone and MAX families. Designers should verify long-term availability through franchised distributors and confirm that legacy Quartus II (or MAX+PLUS II) toolchains support the chosen speed grade. JTAG programming with EPC configuration devices is the standard in-system configuration path.

This page synthesizes franchised distributor pricing (DigiKey, Mouser, Octopart), drop-in same-package alternatives from the EP1K50 family, and practical design notes not consolidated in the original ACEX-1K datasheet family document.

Applications typiques

EP1K50TC144-2 convient pour 6 applications: Industrial Glue Logic and Bus Bridging, Low-Volume ASIC Prototyping, Communication Protocol Bridge, Legacy Equipment Maintenance and Re-Spin, Educational FPGA Development Boards, Parallel-to-Serial Converter and Serializer.

🏭

Industrial Glue Logic and Bus Bridging

The EP1K50TC144-2 fits industrial glue-logic roles because its 2,880 logic elements and 102 user I/Os easily accommodate multi-protocol bus bridges (UART, SPI, I2C, parallel) plus discrete logic consolidation. The 144-pin TQFP package supports standard SMT reflow on FR-4 boards, while the 2.5 V core and 3.3 V-tolerant I/O banks allow direct interfacing with legacy 3.3 V peripherals without external level shifters. Designers can replace multiple 74-series TTL packages with a single FPGA, reducing board area and BOM count while adding design flexibility via JTAG re-programming during field service.

🔧

Low-Volume ASIC Prototyping

The EP1K50TC144-2 is well-suited for ASIC prototyping because the SRAM-based ACEX-1K fabric allows full design re-spin in hours rather than weeks, accelerating pre-silicon verification. The 50,000-gate capacity maps typical mid-complexity ASICs, and the 144-pin TQFP provides enough user I/O to expose ASIC pins for bench characterization. Designers can validate functional behavior, timing margins, and peripheral interfacing before committing to an NRE-heavy ASIC mask set, lowering project risk and time-to-market.

🌐

Communication Protocol Bridge

The EP1K50TC144-2's 200 MHz internal frequency and 102 I/Os support a wide range of protocol bridge implementations, including UART-to-SPI, SPI-to-I2C, parallel-to-LVDS, and PCI-to-ISA legacy interconnects. The 49,152 bits of embedded RAM buffer packet data efficiently, while the 2.5 V core allows 3.3 V peripherals on the same board. Designers integrate encoder/decoder state machines, FIFOs, and DMA engines on a single chip, replacing multi-IC bridges with a flexible, JTAG-reprogrammable solution.

🔧

Legacy Equipment Maintenance and Re-Spin

The EP1K50TC144-2 is ideal for maintaining legacy industrial and military equipment whose original ACEX-1K designs are reaching end-of-life, because the 144-pin TQFP footprint remains drop-in compatible across speed grades. Designers re-spinning PCBs for obsolescence management can substitute an EP1K50TC144-1 or -2 without altering the PCB layout, reusing existing schematics and JTAG programming flows. This dramatically extends the service life of installed systems where re-qualification costs are prohibitive.

🎓

Educational FPGA Development Boards

The EP1K50TC144-2 supports educational and lab development because its 2,880 logic elements and 49,152 bits of embedded RAM are sufficient for soft-core processor implementations, lab exercises, and student projects. The TQFP package is hand-solderable for prototype builds and tolerates multiple rework cycles during coursework. Universities teaching digital design leverage the Quartus II and MAX+PLUS II toolchains, which include free student licenses and reference designs.

📡

Parallel-to-Serial Converter and Serializer

The EP1K50TC144-2 is well-matched to parallel-to-serial conversion applications because its 102 I/O pins accept wide parallel buses while on-chip EABs implement FIFO buffering at line rates up to 200 MHz. Designers use it for camera-link front-ends, legacy parallel display aggregation, and high-speed data acquisition interfaces where converting to fewer-lane LVDS or SERDES links reduces cabling cost. The JTAG interface enables field-upgradeable serializer firmware.

What is the EP1K50TC144-2 FPGA?
The EP1K50TC144-2 is an Intel (formerly Altera) ACEX-1K family FPGA with 50,000 typical gates, 2,880 logic elements, 40,960 system gates, and 102 user I/Os in a 144-pin TQFP package, speed grade -2. According to DigiKey and Mouser distributor listings, it is built on a 2.5 V 0.22 µm CMOS process and is intended for glue logic, ASIC prototyping, and low-volume commercial designs where the TQFP package simplifies SMT assembly compared with BGA alternatives.
Is the EP1K50TC144-2 still in production?
The EP1K50TC144-2 is classified as obsolete by Intel; production has been discontinued and the part is now sourced only from distributor inventory and secondary markets. Per Octopart, 13 distributors still list stock, but lead times can extend and pricing reflects end-of-life scarcity. Designers of new products should migrate to the Cyclone or MAX families for guaranteed long-term supply.
Where can I buy the EP1K50TC144-2?
The EP1K50TC144-2 can be purchased from DigiKey (part detail page 703780), Mouser, Octopart-listed distributors, and authorized resellers such as Avnet. As of 2026-09-07, distributor stock is limited due to obsolete status, so engineers should request quotes from multiple sources and verify date code and RoHS compliance before placing production orders.
What is the price of the EP1K50TC144-2?
The unit price of the EP1K50TC144-2 starts at approximately $48.50 at qty 1, declining to roughly $28.40 at qty 1000 per current distributor listings (as of 2026-09-07). Because the part is obsolete, prices fluctuate with inventory and may include premium surcharges for traceable date codes or RoHS-compliant lots. Bulk quotes should always be confirmed directly with the franchised distributor.
What is the lead time for the EP1K50TC144-2?
Lead time for the EP1K50TC144-2 ranges from immediate (in-stock lots) to 8-12 weeks depending on quantity and distributor inventory depth, as of 2026-09-07. Because the part is end-of-life, large orders often trigger sourcing from secondary-market suppliers with extended lead times. Requesting multiple distributor quotes and a date-code specification reduces the risk of receiving aged stock.
What is the difference between the EP1K50TC144-2 and the EP1K50TC144-1?
The EP1K50TC144-2 is speed grade -2 (commercial, slower), while the EP1K50TC144-1 is speed grade -1 (faster timing closure). Both share the same 144-pin TQFP footprint, 50,000 typical gates, 2,880 logic elements, and 102 user I/Os, so they are pin-compatible drop-in alternatives on the same PCB. Choose -1 for timing-critical designs and -2 for lower-cost, non-timing-critical applications.
Can the EP1K50TC144-1N replace the EP1K50TC144-2 directly?
Yes, the EP1K50TC144-1N is a same-package (144-pin TQFP) drop-in alternative to the EP1K50TC144-2, sharing identical logic capacity and I/O count but offering a faster speed grade. Per the EP1K50 family datasheet, the pinout is consistent across all speed grades of the TC144 package, so PCB rework is not required. This is the most common upgrade path when -2 stock is exhausted.
What is the difference between the EP1K50TC144-2 and the EP1K50QC208-2?
The EP1K50TC144-2 ships in a 144-pin TQFP with 102 user I/Os, while the EP1K50QC208-2 ships in a 208-pin PQFP with 147 user I/Os, providing more I/O capacity at the expense of a larger footprint. Both share the same 50,000-gate ACEX-1K die, so logic capacity is identical. Use the TC144-2 when board area is constrained and 102 I/Os is sufficient; migrate to QC208-2 only if your design requires more than 102 user pins.
Where can I download the EP1K50TC144-2 datasheet?
The official ACEX-1K family datasheet covering the EP1K50TC144-2 is published by Intel (formerly Altera) in the Altera documentation archive, accessible via the Intel Programmable Solutions Group legacy document portal. Third-party datasheet mirrors such as Datasheets.com, FindIC, and DigChip also host the full PDF. Search for "ACEX 1K Device Family Data Sheet" to find the latest revision document.
Where is the pinout for the EP1K50TC144-2?
The pinout for the EP1K50TC144-2 is documented in the ACEX-1K family datasheet and follows the standard 144-pin TQFP pin assignment convention with pin 1 located at the top-left marker. Pin numbers correspond to user I/O banks, dedicated clock inputs (CLK), JTAG (TDI/TDO/TMS/TCK), configuration (MSELn, nCE, nCONFIG, nSTATUS, CONF_DONE), and power/ground pins. The same pinout applies to all EP1K50TC144 speed grades.
How do I configure the EP1K50TC144-2 at power-up?
The EP1K50TC144-2 supports SRAM-based configuration via the IEEE 1149.1 JTAG interface or via an external Altera EPC configuration device in serial or parallel mode. The Quartus II or MAX+PLUS II programmer issues the bitstream through TDI/TCK/TMS/TCK, after which CONF_DONE goes high to indicate successful configuration. Designers typically include a JTAG header on the PCB to enable in-system reprogramming and boundary-scan testing.
What software is required to program the EP1K50TC144-2?
The EP1K50TC144-2 is supported by Altera's legacy Quartus II (version 13.0 or earlier) and MAX+PLUS II design toolchains. Quartus II provides HDL synthesis, place-and-route, timing analysis, and bitstream generation for ACEX-1K devices; MAX+PLUS II remains useful for legacy schematic-based designs. Both toolchains are available through Intel's legacy software archive for download.
Is the EP1K50TC144-2 suitable for new product designs in 2026?
The EP1K50TC144-2 is not recommended for new product designs in 2026 due to its obsolete status and the availability of newer, lower-cost Cyclone and MAX FPGA families from Intel. Designers should select a Cyclone III/IV/V or MAX II/10 device for new projects requiring guaranteed long-term supply, lower power, and modern toolchain support. The EP1K50TC144-2 remains appropriate for maintaining legacy equipment and re-spinning existing ACEX-1K designs.
What are the key specifications of the EP1K50TC144-2 that engineers should know?
The EP1K50TC144-2 delivers 50,000 typical gates, 2,880 logic elements organized into 360 LABs, 49,152 bits of embedded RAM via EABs, 102 user I/O pins, 200 MHz maximum internal frequency, 2.5 V core, 0.22 µm CMOS process, and 144-pin TQFP packaging per the ACEX-1K family datasheet. It supports JTAG (IEEE 1149.1) configuration and is targeted at commercial-temperature, glue-logic, and low-volume ASIC prototyping applications.

Guide de sélection

Choose the EP1K50TC144-2 when you need a 144-pin TQFP FPGA with 2,880 logic elements for glue logic, ASIC prototyping, or legacy equipment maintenance, and your design is not timing-critical enough to demand a -1 speed grade. Choose the EP1K50TC144-1N as a drop-in upgrade when -2 stock is exhausted or timing margin is needed. Choose the EP1K30TC144-2 when 1,728 logic elements are sufficient and you want to reduce cost by ~40%. Choose the EP1K10TC144-2 only for very small designs where 576 LEs suffice. None of these are recommended for new product designs in 2026 - migrate to Cyclone III/IV/V or MAX II/10 for long-term supply and modern toolchain support.

Principaux différenciateurs

  • Largest logic capacity in the EP1K50 TC144 pinout family (vs EP1K30TC144-2)
  • Lower cost than faster speed grade (vs EP1K50TC144-1N)
  • More embedded RAM than lower-density ACEX-1K siblings (vs EP1K10TC144-2)

Notes de conception

Estimated: the EP1K50TC144-2 draws approximately 100-300 mA from the 2.5 V VCCINT rail at full utilization, depending on clock rate and toggle activity. Each VCCINT pin supplies one section of the core; designers must populate all VCCINT pins with proper decoupling (0.1 µF ceramic + 10 µF bulk) to minimize supply droop during simultaneous switching. VCCIO bank supplies must be tied to 3.3 V (or 2.5 V, per I/O standard selection), and unused I/O banks must still receive power to keep input buffers in a defined state.

The 144-pin TQFP package uses 0.5 mm pitch leads, which require fine-pitch SMT stencil apertures and a 4-mil solder paste deposit for reliable assembly. Place all decoupling capacitors within 3 mm of their respective VCCINT, VCCIO, and GND pins to minimize parasitic inductance. Include a 4-layer PCB with continuous ground and power planes under the FPGA, and route all 102 user I/O traces with matched length groups if any pair is used as a parallel bus or LVDS link.

Do not connect MSEL0/MSEL1 to arbitrary logic levels; they must be tied to specific combinations of VCCINT or GND to select the correct configuration mode (AS, AP, PS, JTAG). A floating MSEL pin leaves the device in an undefined configuration state. Similarly, nCONFIG must be driven by a clean POR supervisor or RC delay, not left floating, otherwise the device may not initiate configuration at power-up.
