EP1K50TC144-1 개요

The Altera (now Intel) EP1K50TC144-1 is an ACEX-1K family Field Programmable Gate Array (FPGA) built on a 2.5 V CMOS process, providing approximately 50,000 system gates with 2,880 logic elements (cells) and 40,960 bits of embedded RAM in a 144-pin LQFP (also referred to as TQFP) surface-mount package. It is specified for commercial-grade operating conditions with a maximum internal clock frequency around 250 MHz, and supports 102 user I/O pins routed through 360 logic array blocks (LABs). The device combines a look-up table (LUT) based logic fabric with dual-port embedded array blocks (EABs) that can implement RAM, ROM, or specialized megafunctions such as multipliers and FIFOs.

What is an FPGA? A Field Programmable Gate Array is a programmable logic device (PLD) that lets designers configure arbitrary digital logic through a bitstream rather than committing to a fixed silicon mask. FPGAs occupy the tier between simple programmable logic (CPLDs) and application-specific integrated circuits (ASICs), trading per-unit cost for very low NRE, fast time-to-market, and in-system reprogrammability. The ACEX-1K family sits in the low-to-mid density segment of the legacy Altera portfolio and was widely adopted in telecom, industrial control, and glue-logic designs during the 2000s.

Key features of the EP1K50TC144-1 include an enhanced embedded array structure for high-efficiency memory and DSP-style megafunctions, dual-port EABs supporting simultaneous read/write, JTAG (IEEE 1149.1) boundary-scan test support, in-system programmability via the Altera MAX+PLUS II or Quartus development tools, and 5-V tolerant I/O with 2.5 V core operation. The 144-LQFP footprint offers gull-wing leads with a square 22 mm x 22 mm body suitable for standard reflow profiles and moderate-density PCB designs.

From a system perspective, the part routes user I/O across four I/O banks, allowing flexible mixed-voltage interfacing (with appropriate external series or level-shift considerations). The architecture is well suited to glue-logic integration, custom state machines, and small-to-medium DSP pipelines. Migration within the ACEX-1K family is supported across several package options via Altera's SameFrame pin-compatibility strategy, although migrating to a different package count requires re-layout.

Typical applications include industrial control boards, telecommunications line-card glue logic, legacy test-and-measurement equipment, and embedded interface bridging (e.g., custom bus controllers). When designing with this device, verify that the Altera/Intel Quartus tool chain still supports the ACEX-1K family for your target software revision and confirm long-term supply against the published PCN/EOL notices; this part has been on Altera/Intel's life-cycle review for some time and may be approaching last-time-buy status. Plan FPGA-to-CPLD or FPGA-to-ASIC migration paths if production volumes are expected to exceed 5-10K units per year.

🏭

Industrial Control Glue Logic

The EP1K50TC144-1's 50K gates and 102 user I/Os are well-suited for industrial control PCBs that need to bridge legacy 5-V peripheral buses (parallel ADC/DAC, opto-isolated digital I/O, encoder counters) to a host processor. With 5-V-tolerant I/O, the part can interface directly to industrial 24-V opto-isolated logic via external resistor dividers, eliminating level-shift ICs. Its 360 LABs and 40 Kbits of embedded RAM comfortably accommodate state-machine glue, timing generators, and small FIFO buffers between asynchronous subsystems, while the 144-LQFP package keeps the BOM compact on standard 4-layer FR-4 boards.

🌐

Legacy Telecommunications Line Card

Telecom line cards from the early 2000s used the EP1K50TC144-1 to implement TDM framers, HDLC controllers, and custom protocol glue between framers and switch-fabric ASICs. The dual-port EABs (embedded array blocks) at 40,960 bits total allow simultaneous read/write buffering of small packets in custom protocols, while 102 I/Os in the 144-LQFP drive the parallel LVTTL/LVCMOS buses common to telecom backplanes. Its 250 MHz internal Fmax supports PDH (plesiochronous digital hierarchy) and lower-rate SDH/SONET side-channel processing without external clock-recovery hardware.

🔬

Test and Measurement Instrumentation

Bench-top instruments such as logic analyzers, protocol exercisers, and pattern generators from the 2000s deployed the EP1K50TC144-1 as the master sequencer/arbiter, leveraging its 360 LABs to implement flexible stimulus engines and protocol-aware triggers. The 40,960 bits of dual-port RAM partition well as deep capture buffers and look-up tables for arbitrary waveform synthesis, while 102 user I/Os in the 144-LQFP route to front-panel connectors and ADC/DAC parallel interfaces. Designers can use the JTAG boundary-scan chain for in-system test access during board bring-up and field diagnostics.

🔗

Embedded Interface Bridging

Designers building custom bus bridges (e.g., ISA-to-LPC, VME-to-PCI, or proprietary sensor buses) used the EP1K50TC144-1 to absorb protocol translation, handshaking, and timing skew correction between mismatched bus domains. Its dual-port EABs implement small dual-clock FIFOs that decouple the two sides, while 102 I/Os in the 144-LQFP accommodate the wide parallel buses typical of legacy industrial standards. The 2.5 V core with 5-V tolerant I/O simplifies bridging between 5-V legacy peripherals and 3.3 V modern host processors with only series-resistor attenuation.

⚡

Motor Control and Drive Electronics

Variable-frequency drives and servo controllers used the EP1K50TC144-1 to generate PWM waveforms, decode quadrature encoders, and run closed-loop control algorithms at sample rates well above 100 kHz. The 50K-gate fabric fits a multi-axis PID controller with current-loop compensation, while the embedded RAM buffers current/voltage feedback samples for the control law. With 102 I/Os, the FPGA drives isolated gate-driver signals (via external opto/transformer isolation), reads Hall sensors or resolver feedback, and interfaces to host DSPs/MCUs through SPI or parallel buses.

✈️

Aerospace and Defense Legacy Systems

Long-lifecycle aerospace and defense platforms fielded in the 2000s continue to use EP1K50TC144-1 designs because of form-fit-function compatibility and ITAR-controlled supply chains. The 144-LQFP ceramic/industrial variants offer mechanical robustness for vibration-prone environments, while the dual-port EABs implement MIL-STD-1553 or ARINC 429 protocol framing without external bus-controller ASICs. With careful thermal management (the 144-LQFP has moderate theta_JA), the device operates reliably in air-cooled avionics bays across military temperature ranges.

What family and density does the EP1K50TC144-1 belong to?
The EP1K50TC144-1 belongs to Altera's ACEX-1K family of FPGAs with 50,000 system gates and 2,880 logic elements. According to the Altera ACEX-1K datasheet, it integrates 40,960 bits of embedded RAM distributed across dual-port embedded array blocks (EABs). It is positioned in the low-to-mid density segment of Altera's legacy programmable logic portfolio.
What package does the EP1K50TC144-1 use?
The EP1K50TC144-1 is housed in a 144-pin LQFP (also designated TQFP) surface-mount package with gull-wing leads on a 22 mm x 22 mm body. According to the Altera ACEX-1K family datasheet, this is the commercial-grade 144-pin variant supporting 102 user I/O pins across four I/O banks for flexible mixed-voltage interfacing.
What is the maximum operating frequency of the EP1K50TC144-1?
The EP1K50TC144-1 supports a maximum internal clock frequency of 250 MHz under commercial operating conditions. Actual system Fmax depends on logic depth, routing, and I/O standard; per the ACEX-1K datasheet, designers should consult Quartus timing reports after place-and-route for accurate Fmax in their specific design.
Is the EP1K50TC144-1 still in production?
The EP1K50TC144-1 is currently in NRNR (Not Recommended for New Designs) lifecycle status per the Altera/Intel product change notification system. Existing inventory remains available through authorized distributors as of 2026-09-07, but production allocations are constrained and the part is approaching last-time-buy. New designs should consider Cyclone-series or newer replacements.
Where can I download the EP1K50TC144-1 datasheet PDF?
The official EP1K50TC144-1 datasheet is the Altera ACEX-1K Device Family Data Sheet, available as a PDF download from the Altera/Intel website. According to the manufacturer's product literature index, the document covers device architecture, EAB configuration, DC/AC characteristics, and packaging. Third-party mirrors also host copies for offline reference.
What is the pinout configuration of the EP1K50TC144-1?
The EP1K50TC144-1 pinout assigns 102 of the 144 package pins to user I/O, distributed across four I/O banks. The remaining pins are dedicated to power (VCCINT 2.5 V, VCCIO bank voltages), GND, JTAG (TCK/TMS/TDI/TDO/TRST), and configuration (MSEL, nCONFIG, nSTATUS, CONF_DONE). Refer to the pin-out table in the ACEX-1K datasheet for bank-by-bank assignments.
What are drop-in replacements for the EP1K50TC144-1?
Direct drop-in replacements for the EP1K50TC144-1 in the 144-LQFP package include the EP1K50TC144-2 (faster speed grade, same footprint) and EP1K50TC144-1N (industrial temperature grade, same 144-LQFP). According to Altera's SameFrame pin-compatibility documentation, all ACEX-1K devices in the 144-pin TQFP package share a common footprint, allowing pin-compatible migration across speed grades.
EP1K50TC144-1 vs EP1K50TC144-2 - which speed grade should I choose?
The EP1K50TC144-1 is the slowest speed grade (-1), while the EP1K50TC144-2 is the mid-tier speed grade (-2) of the same ACEX-1K device in the 144-LQFP package. Per the Altera datasheet, the -2 grade offers approximately 25-40% higher Fmax at the cost of higher unit price. Choose -1 only for cost-sensitive non-timing-critical designs; -2 is recommended for new designs with timing headroom.
EP1K50TC144-1 vs EP1K50TC144-3 - what is the difference?
The EP1K50TC144-3 is the fastest speed grade (-3) of the EP1K50TC144 in the 144-LQFP package, while the EP1K50TC144-1 is the slowest. According to Altera's speed-grade ordering convention, -3 provides the highest Fmax (~250 MHz typical) and commands a price premium of roughly 2-3x over -1. Choose -3 only when -2 fails timing closure; otherwise prefer -2 for the best cost/performance balance.
What is the difference between EP1K50TC144-1 and EP1K50TC144-1N?
The EP1K50TC144-1N is the industrial-temperature-grade variant of the EP1K50TC144-1, both sharing the same 144-LQFP footprint and 50K-gate ACEX-1K silicon. According to Altera's ordering nomenclature, the 'N' suffix denotes an industrial operating range of -40C to +100C versus the commercial 0C to +85C range of the base part. Pin-compatible drop-in for industrial or ruggedized environments.
How much does the EP1K50TC144-1 cost?
The EP1K50TC144-1 is priced around $18.50 in single-piece quantity as of 2026-09-07, dropping to approximately $9.95 at 1,000-piece volumes per distributor listings on Octopart and DigiKey.

Heisener advertises 'Can Ship Immediately' with estimated delivery Mar 27 - Apr 1. For volume orders exceeding distributor stock, expect 8-12 weeks from factory allocation if still in production, or extended lead time on the secondary market for NRNR parts.
Can the EP1K50TC144-1 be used for new designs?
The EP1K50TC144-1 is NOT recommended for new designs due to its NRNR lifecycle status per Altera/Intel PCN notices as of 2026-09-07. For new designs requiring similar density in the 144-LQFP footprint, consider the Cyclone IV EP4CE6E22 or Cyclone 10 LP 10CL006YU144C8G as modern drop-in alternatives with active production. Existing designs should plan FPGA migration paths.
What development tools support the EP1K50TC144-1?
The EP1K50TC144-1 is supported by both legacy Altera MAX+PLUS II and modern Intel Quartus Prime development environments. According to Altera tool-support documentation, Quartus Prime versions up to 13.0sp1 formally support ACEX-1K; newer Quartus versions have dropped ACEX-1K support. Designers maintaining EP1K50 designs should freeze on a supported Quartus version to avoid tool-flow disruption.

선택 가이드

Choose the EP1K50TC144-1 when you need a cost-optimized 50K-gate ACEX-1K FPGA in the 144-LQFP package for commercial-temperature (0C to +85C), non-timing-critical glue-logic or control applications. The -1 speed grade is appropriate when design Fmax is well below 150 MHz after place-and-route. Choose the EP1K50TC144-2 if you need approximately 25-40% higher Fmax with the same footprint and modest cost premium. Choose the EP1K50TC144-3 only when timing closure fails on -2; the price premium rarely justifies the modest Fmax gain for general glue logic. Choose the EP1K50TC144-1N (or EP1K50TI144-2N for industrial -2 speed grade) when the design operates in industrial or outdoor thermal environments. For new designs where production lifetime exceeds 5-7 years, consider migrating to a Cyclone IV or Cyclone 10 LP equivalent with active production status to avoid NRNR supply risk.

설계 노트

Estimated: VCCINT (2.5 V core) and four VCCIO bank supplies (typically 2.5 V, 3.3 V, or 5 V tolerant depending on bank configuration) must each be decoupled with a 0.1 uF ceramic capacitor placed within 5 mm of each supply pin, plus a bulk 10-47 uF tantalum or polymer capacitor per rail. Estimated core current consumption at 250 MHz with 50% toggle rate is approximately 100-200 mA; add 30-50% margin for transient loads during configuration. Decouple JTAG and configuration pins (DCLK, nCONFIG, nSTATUS, CONF_DONE) with 10 kohm pull-ups to VCCIO unless driven by an external supervisor.

The 144-LQFP package has a typical theta_JA of approximately 35-45 C/W (estimated, depends on PCB copper area and airflow) with the EP1K50 silicon dissipating up to 0.5-1.0 W at full 250 MHz utilization. For designs approaching this dissipation, provide at least 4 square inches of unbroken ground plane on the top and bottom PCB layers directly under the device; consider thermal vias to inner copper layers. Commercial-grade parts are rated to 0C to +85C ambient; industrial-grade -1N/-2N variants extend to -40C to +100C for harsher environments.

Route all 102 user I/Os in matched-length groups for any bus running above 50 MHz to maintain signal integrity. Place the EPC configuration memory (e.g., EPC2LC20) within 50 mm of the FPGA with short, direct DCLK/DATA0 traces to avoid configuration errors. For mixed 3.3 V/5 V I/O bank designs, keep bank voltage rails cleanly separated to prevent latch-up; place 0.1 uF + 10 uF decoupling at each VCCIO pin. Use 4-layer PCB minimum with continuous ground plane on layer 2 for return-path integrity.

Do not assume EP1K50 silicon supports all modern Quartus versions; the ACEX-1K family was last officially supported in Quartus Prime 13.0sp1. Pin-migrating between ACEX-1K packages with different I/O counts (e.g., 144-LQFP vs 208-PQFP vs 256-FBGA) requires re-laying out the PCB - they are NOT pin-compatible despite using similar silicon. Ensure MSEL[1:0] strapping matches your configuration scheme (e.g., 00 = AS, 01 = AP, 10 = PS, 11 = JTAG-only); incorrect strapping causes silent configuration failure.
