EP1K50TI144-2 Présentation

The Intel (formerly Altera) EP1K50TI144-2 is a member of the ACEX-1K family of Field Programmable Gate Arrays (FPGAs), delivering 50,000 typical gates and 2,880 logic elements (LEs) in a 144-pin LQFP package. Operating from a 2.5 V core supply (2.375 V to 2.625 V range), this device provides 102 user I/O pins and is rated for industrial temperature operation (-40 °C to +85 °C). The "-2" speed grade positions this variant in the mid-performance tier of the ACEX-1K lineup, balancing timing margin against unit cost.

An FPGA (Field Programmable Gate Array) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be re-programmed to implement arbitrary digital logic. ACEX-1K sits within the broader taxonomy of programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) / FPGAs -> SRAM-based LUT FPGAs -> low-cost FPGAs -> embedded array FPGAs. The EP1K50TI144-2 specifically uses a Look-Up Table (LUT)-based architecture with embedded array blocks (EABs) that support dual-port RAM, ROM, FIFO, and specialized megafunctions, enabling system-on-a-programmable-chip (SOPC) integration.

Key features of the EP1K50TI144-2 include 40,960 RAM bits organized as embedded array blocks, 360 Logic Array Blocks (LABs), and built-in support for LVTTL, LVCMOS, SSTL, and HSTL I/O standards. The device also integrates a JTAG boundary-scan test interface compliant with IEEE 1149.1, an in-system programmability (ISP) port, and a dedicated configuration circuitry that accepts bitstreams from EPC configuration PROMs or via passive serial/parallel controllers.

Typical applications for the EP1K50TI144-2 include glue-logic replacement, industrial control interfaces, low-density telecommunications glue logic, and bridge/protocol conversion such as UART-to-PCI or I2C-to-parallel. The 144-LQFP package is hand-solder-friendly and compatible with low-cost PCB fabrication, making it well-suited for prototype runs and legacy system maintenance. Designers migrating to this part should note that ACEX-1K devices in the same 144-pin TQFP/LQFP package are pin-compatible across the family, allowing migration between EP1K10, EP1K30, and EP1K50 density points on the same PCB layout.

This page synthesizes distributor pricing, ACEX-1K family pin-compatible alternatives, and practical design notes for the EP1K50TI144-2 that are not collated in the legacy ACEX 1K Device Family datasheet.

Applications typiques

EP1K50TI144-2 convient pour 6 applications: Industrial Glue Logic Replacement, Legacy Protocol Bridge and Bus Converter, Test and Measurement Instrumentation Front-End, Telecommunications Glue Logic and Framing, Motor Control and Drive Interface, Aerospace Prototype and Avionics Bus Interface.

🏭

Industrial Glue Logic Replacement

The EP1K50TI144-2 is well suited for replacing multiple discrete 74-series glue-logic ICs in industrial control boards. With 2,880 LEs and 102 user I/O pins, the device can absorb an entire 7400-series BOM (buffers, latches, transceivers, encoders) into a single chip, cutting PCB area by 60-70% and reducing component count. Its 2.5 V core and LVTTL/LVCMOS I/O support connect directly to legacy 3.3 V microcontrollers and 5 V peripherals via series resistors. Designers should budget for an EPC2/EPC8 boot PROM and 4-layer PCB for signal integrity.

🌐

Legacy Protocol Bridge and Bus Converter

The EP1K50TI144-2 fits protocol-bridge designs such as UART-to-PCI, I2C-to-parallel, or SPI-to-ISA conversion used in legacy telecom and industrial equipment. The 40,960 bits of embedded RAM accommodate FIFOs up to 5 KB without external SRAM, and the 360 LABs deliver deterministic propagation delays suitable for bit-banging legacy bus timing. The 144-LQFP package is hand-rework-friendly for field upgrades, and SameFrame pin-compatibility lets engineers migrate to EP1K100TI144-2 in the same PCB footprint as bridge complexity grows.

🔬

Test and Measurement Instrumentation Front-End

The EP1K50TI144-2 serves as the digital back-end for low-cost test instruments such as logic analyzers, pattern generators, and protocol exercisers. Its 102 I/O pins support up to 96 channels of buffered digital I/O at 50 MHz using the -2 speed grade, sufficient for capturing parallel bus traffic at up to 25 MHz. The 2.5 V core delivers low dynamic power (~0.5 W typical) compared to larger FPGAs, making the part attractive for portable or USB-powered instruments. Designers typically implement state machines for trigger sequencing and store captured data in the embedded EAB RAM.

📡

Telecommunications Glue Logic and Framing

In legacy telecom systems (T1/E1 framers, DS3 multiplexers, SONET/SDH tributary equipment), the EP1K50TI144-2 handles framing, alarm insertion, and clock-data recovery glue logic. The 360 LABs run small HDLC controllers and bit-error-rate testers (BERTs) in parallel, while the 40,960 bits of embedded RAM buffer tributary payloads. The -2 speed grade comfortably meets 51.84 MHz STS-1 timing. Industrial temperature grade supports outside-plant and central-office deployments where ambient temperatures vary.

🏭

Motor Control and Drive Interface

The EP1K50TI144-2 is deployed as the digital interface between microcontrollers/MOSFET gate drivers in industrial motor drives, BLDC controllers, and stepper drivers. The 102 I/O pins handle quadrature encoder feedback (QEP), Hall-sensor inputs, PWM outputs to gate drivers, and fault interlocks all within a single chip. Industrial-temperature operation (-40 to +85 °C) tolerates the elevated ambient inside a drive enclosure. The 2.5 V core and 3.3 V I/O simplify interface to modern Cortex-M microcontrollers, and embedded EABs store sine-table and commutation look-up tables.

️

Aerospace Prototype and Avionics Bus Interface

The EP1K50TI144-2 is used in legacy aerospace prototypes for ARINC 429, MIL-STD-1553, and discrete avionics bus interface cards. The 2,880 LEs encode/decode up to 8 ARINC 429 channels or implement a single MIL-STD-1553 BC/MT/RT in soft logic, while the industrial temperature range covers most cockpit and equipment-bay environments. SameFrame pin-compatibility lets designers scale to EP1K100TI144-2 for higher-channel-count avionics boxes without PCB rework. Note that aerospace certification programs typically require an obsolescence-management plan given the part's end-of-life status.

What is the EP1K50TI144-2 and what family does it belong to?
The EP1K50TI144-2 is an FPGA from the Intel (formerly Altera) ACEX-1K family, delivering 50,000 typical gates and 2,880 logic elements in a 144-pin LQFP package. According to the ACEX 1K Device Family datasheet, ACEX-1K devices combine a Look-Up Table (LUT) architecture with embedded array blocks (EABs) for on-chip dual-port RAM, ROM, and FIFO functions, enabling low-cost system-on-a-programmable-chip (SOPC) integration.
How many user I/O pins does the EP1K50TI144-2 have?
The EP1K50TI144-2 provides 102 user I/O pins in the 144-pin LQFP package. According to the DigiKey product listing, the device exposes 6 dedicated inputs plus 102 general-purpose I/Os for a total of 108 user-accessible pins. The remaining pins are reserved for power (VCCINT, VCCIO), ground, JTAG (TCK/TMS/TDO/TDI), and configuration (nCONFIG, nSTATUS, CONF_DONE, DCLK).
What is the core supply voltage of the EP1K50TI144-2?
The EP1K50TI144-2 operates from a 2.5 V core supply (VCCINT) with an allowed range of 2.375 V to 2.625 V. According to the Altera ACEX-1K datasheet, the device supports multiple I/O voltages (VCCIO) including 3.3 V, 2.5 V, and 1.8 V for mixed-voltage interfacing with legacy 5 V-tolerant logic via external bus-hold or clamping.
What is the operating temperature range of EP1K50TI144-2?
The EP1K50TI144-2 is graded for industrial-temperature operation from -40 °C to +85 °C. According to the partstack listing, the device is marked with an "I" temperature designator in the MPN. Designers needing commercial (0 °C to +70 °C) operation should select the non-"I" suffix variant EP1K50TC144-2.
What is the difference between EP1K50TI144-2 and EP1K50TC144-2?
The EP1K50TI144-2 is the industrial-temperature (-40 °C to +85 °C) variant of the EP1K50 in the 144-pin TQFP package with -2 speed grade. The EP1K50TC144-2 is the commercial-temperature (0 °C to +70 °C) variant. Both share the same 2,880 LEs, 50,000 gates, and 102 I/O pins; only the operating temperature window differs, making them drop-in replacements for non-extreme environments.
What is the price of EP1K50TI144-2?
As of 2026-09-07, the EP1K50TI144-2 lists at approximately USD 48.50 in single-piece quantity, dropping to USD 27.85 at 1,000-piece reels per the XAIPART tier table. The part is marked obsolete on Intel's PCN register, so stock availability is limited to remaining distributor inventory and the used market; lead times may extend beyond 12 weeks on long-outstanding orders.
Where can I buy the EP1K50TI144-2?

Lead time for the EP1K50TI144-2 is 8 to 14 weeks as of 2026-09-07 due to its obsolete lifecycle status. Stock exists at franchised distributors and XAIPART, but no new wafer production is scheduled. Customers requiring long-term supply should consider ACEX-1K pin-compatible variants like the EP1K100TI144-2 or migrating to a Cyclone series FPGA.
Is the EP1K50TI144-2 still in production?
No, the EP1K50TI144-2 is classified as obsolete by Intel (formerly Altera). According to Intel's product change notification register, the ACEX-1K family was discontinued in the mid-2000s, and remaining inventory is sold through distribution. New designs should target Cyclone II/III/IV or MAX II/10 equivalents.
What is the best drop-in replacement for EP1K50TI144-2?
The best drop-in replacements for the EP1K50TI144-2 are same-package ACEX-1K variants: EP1K30TI144-2 (smaller, 30K gates), EP1K10TI144-2 (10K gates), and the EP1K100TI144-2 (larger, 100K gates). All four share the 144-pin TQFP footprint and pin-compatible I/O map per the ACEX-1K family migration guide. For modern replacements, the Cyclone series (EP1C6, EP1C12, EP1C20) requires PCB rework due to different ball/pin assignments.
EP1K50TI144-2 vs EP1K100TI144-2: which is better for high-density glue logic?
The EP1K100TI144-2 is the better choice for high-density glue logic, offering 100,000 typical gates and 4,992 LEs compared to the EP1K50TI144-2's 50,000 gates and 2,880 LEs. Both parts share the same 144-LQFP package and 102 I/O pins, making them drop-in compatible on the same PCB. Choose EP1K100 only if design utilization exceeds 80% of the EP1K50; otherwise the EP1K50TI144-2 reduces per-unit cost.
Where can I download the EP1K50TI144-2 datasheet PDF?
The EP1K50TI144-2 datasheet is available as a PDF from the Altera/Intel archive at https://www.alterasemi.com/datasheet/alterasemi/EP1K50TI144-2.pdf and from datasheets.com. The legacy document is titled "ACEX 1K Device Family (2.5V)" and contains the complete electrical specification, JTAG BSDL file references, configuration timing, and SameFrame pin-migration tables for the entire ACEX-1K family.
Where do I find the EP1K50TI144-2 pinout?
The EP1K50TI144-2 pinout is published in the ACEX 1K Device Family datasheet (Chapter: Pin Information). The 144-LQFP pin assignment uses standard counter-clockwise numbering with pin 1 at the top-left dot marker. The XAIPART product page renders the full pin diagram and pin-by-pin descriptions from the selected package_svg_key (lqfp-144).
Is the EP1K50TI144-2 suitable for new industrial designs in 2026?
The EP1K50TI144-2 is not recommended for new industrial designs in 2026 due to its obsolete lifecycle status and lack of long-term supply commitment. Existing designs should remain on the EP1K50TI144-2 for maintenance only. For new designs targeting industrial-grade operation, use the Cyclone IV E family (EP4CE6, EP4CE10) or MAX 10 (10M02, 10M08) with enhanced tools, longer supply, and modern features such as on-chip ADC and Nios II soft-core support.
What are the key specifications of EP1K50TI144-2 that engineers should know?
Engineers should know these EP1K50TI144-2 specifications: 2,880 logic elements (LEs) in 360 LABs; 50,000 typical gates; 40,960 bits of embedded RAM; 102 user I/O pins; 144-LQFP package; 2.5 V core supply (2.375 V to 2.625 V); industrial temperature range (-40 °C to +85 °C); -2 speed grade; SRAM configuration with EPC PROM boot; JTAG (IEEE 1149.1) boundary scan; LVTTL/LVCMOS/SSTL/HSTL I/O support.

Guide de sélection

Choose the EP1K50TI144-2 when you need 50K gates of ACEX-1K logic in a hand-solderable 144-LQFP package for industrial-temperature applications. It is the sweet-spot part in the ACEX-1K family: smaller variants (EP1K10TI144-2, EP1K30TI144-2) lack density for multi-protocol bridges, while larger variants (EP1K100TI144-2) waste silicon for typical glue-logic tasks. Use the commercial-temperature EP1K50TC144-2 only if the operating environment stays between 0 °C and +70 °C - the part is otherwise identical and cheaper. Use the -1 speed-grade EP1K50TI144-1 only when timing margin allows a 10-15% Fmax reduction in exchange for marginally lower cost. For modern designs, prefer Cyclone IV E (EP4CE6) or MAX 10 (10M08) unless obsolescence-management plan covers the EP1K50 supply.

Principaux différenciateurs

  • Highest LE density in a hand-solderable 144-LQFP ACEX-1K footprint (vs EP1K30TI144-2)
  • Drop-in upgrade path to 100K-gate ACEX-1K on the same PCB (vs EP1K100TI144-2)
  • Industrial-temperature operation suitable for outside-plant deployments (vs EP1K50TC144-2)

Notes de conception

The EP1K50TI144-2 requires a clean 2.5 V core supply (VCCINT) capable of delivering up to 300 mA during configuration and up to 200 mA in steady-state operation. Use a low-dropout regulator such as a TI TPS79325 or LT3021 with at least 25% current headroom. Place 10 µF + 0.1 µF decoupling capacitors within 5 mm of every VCCINT/GND pair. VCCIO must ramp within ±600 µs of VCCINT to avoid latch-up; sequence VCCINT before VCCIO or use a dual-output LDO with tracking.

The 144-LQFP package has 0.5 mm pitch leads; PCB land pattern must follow IPC-7351 nominal-density guidelines with 0.30 mm pad width and 0.20 mm solder mask sliver. Use a 4-layer stackup with a continuous ground plane under the device. Tie all unused I/O pins to logic-low or logic-high through the Quartus II assignment editor (do not leave them floating). Add a 4.7 kΩ pull-up to VCCIO on nCONFIG, nSTATUS, and CONF_DONE for reliable boot.

Three common pitfalls: (1) Failing to populate an EPC configuration PROM and assuming the FPGA will boot from internal flash - the EP1K50TI144-2 is SRAM-based and loses configuration on every power-cycle. (2) Mixing VCCIO and VCCINT rails - the I/O bank voltage must match the peripheral logic level, otherwise inputs will be clamped and outputs will be over-driven. (3) Using a non-validated JTAG programmer (such as a generic FT2232H-based cable) without an Altera-compatible buffer - the TCK signal is sensitive to cable capacitance above 25 pF, which causes configuration failures.
