EP1K50TC144-2 概述
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.

典型应用
EP1K50TC144-2 适用于 6 应用s: 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.
推荐
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.
推荐
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.
推荐
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.
推荐
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.
推荐
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.

- More embedded RAM than lower-density ACEX-1K siblings （对比 EP1K10TC144-2)
设计说明
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.
