EP1K50TI144-1X Ringkasan

The Intel / Altera EP1K50TI144-1X is a member of the ACEX 1K family of Field Programmable Gate Arrays, integrating 50,000 equivalent gates and 2,880 logic elements across 360 Configurable Logic Blocks (CLBs) in a 144-pin TQFP/LQFP package with 0.5 mm pitch. The device uses a 2.5 V CMOS core (2.375 V to 2.625 V supply range) and supports a maximum clock frequency of approximately 90 MHz, with 102 general-purpose user I/O pins and 6 dedicated input pins for clock and global control signals.

An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs), embedded memory blocks (EABs / ESBs in ACEX 1K), and programmable routing. FPGAs belong to the semiconductor hierarchy: programmable logic IC -> PLD -> digital IC -> integrated circuit. Unlike fixed-function ASICs, FPGAs are configured by the user after manufacture using an HDL bitstream and a vendor toolchain (Quartus for ACEX 1K), making them ideal for prototyping, low-volume production, and glue-logic consolidation.

Key features of the EP1K50TI144-1X include on-chip SRAM-based configuration (volatile, requires external configuration device on power-up), embedded array blocks (EABs) for efficient memory and multiplier implementation, multi-volt I/O support for interfacing to 2.5 V, 3.3 V, and 5 V systems, and an industrial operating temperature range (-40 C to +85 C) suitable for factory and outdoor equipment. The ACEX 1K architecture combines look-up-table based logic fabric with EAB memory, giving it a hybrid advantage over pure LUT-based contemporaries.

In the broader ACEX 1K portfolio the EP1K50 sits between the EP1K10 (10K gates) and EP1K100 (100K gates), making it a sweet spot for medium-complexity glue logic, bridge designs, and pre-ASIC prototyping. The "-1" speed grade is the slowest of three available grades and offers the lowest cost; the "-2" and "-3" grades provide higher Fmax but consume more power. The "X" suffix indicates industrial temperature grade and tape-and-reel packaging per the Altera ordering code convention.

Typical applications include industrial control glue logic, communication protocol bridges (UART/SPI/I2C consolidation), legacy peripheral replacement, test and measurement front-ends, and low-volume embedded control where a microcontroller's fixed peripherals are insufficient. Designers transitioning away from discrete 74-series TTL logic or older CPLDs use this part to consolidate 5 to 20 chips onto a single programmable device.

When designing with the EP1K50TI144-1X, plan for an external EPC configuration ROM (e.g., EPC2 or EPC4) on the board because the ACEX 1K configuration is volatile. Use the Quartus II design tool (legacy version 9.0 or later) for HDL entry, synthesis, and place-and-route; the bitstream must be reformatted if migrating to a different package.
