EP1K50TC144-1N Présentation

The Intel (formerly Altera) EP1K50TC144-1N is a member of the ACEX 1K family of 2.5V field-programmable gate arrays (FPGAs) providing low-cost system-on-a-programmable-chip (SOPC) integration. Housed in a 144-pin TQFP surface-mount package, it integrates 2,880 logic elements distributed across 360 logic array blocks (LABs), delivers up to 199,000 equivalent gates, and includes 40,960 bits of embedded dual-port RAM. The device operates from a 2.375V to 2.625V supply (typical 2.5V) and supports 102 user I/O pins.

An FPGA (Field-Programmable Gate Array) is a programmable logic device that combines the architectural density of a gate array with user-configurable interconnect and logic. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs) -> logic arrays -> programmable semiconductors. The ACEX 1K family was engineered specifically for high-volume, cost-sensitive applications and combines embedded array blocks (EABs) for memory and specialized megafunctions with a logic array fabric optimized for general-purpose logic. This dual structure distinguishes ACEX 1K from pure CPLDs and from later Cyclone families.

Key features include a maximum operating frequency of 180 MHz, built-in IEEE 1149.1-compliant JTAG boundary-scan test (BST) circuitry, PCI Local Bus Specification Revision 2.2 compliance for 5.0V operation in the -1 speed grade, an enhanced embedded array for implementing megafunctions, and dual-port RAM support. The CMOS process and 2.5V core reduce power consumption relative to 5V and 3.3V predecessors while preserving adequate speed for glue logic, bus interface, and moderate-complexity DSP tasks.

Typical applications span low-cost system-on-a-programmable-chip designs, PCI bus bridges, communications infrastructure glue logic, industrial control and instrumentation, video/image processing front-ends, and DSP coprocessor interfacing. Designers leverage the embedded array blocks to instantiate memory, multipliers, and other megafunctions without consuming general logic resources, which preserves logic element count for state machines and datapath control.

When designing with this device, allocate I/O banks carefully because the 2.5V core requires careful level-shifting to interface with 3.3V and 5V peripherals. The TQFP-144 footprint supports hand-soldering and prototype rework but is not the highest-density option in the ACEX 1K line; designers targeting smaller board area should evaluate QFP-208 or BGA packages. Programming is supported by the legacy MAX+PLUS II toolchain as well as selected Quartus versions.
