EP1K50TC144-2 Ringkasan

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.
