EP20K100TC144-2

Overview

The Altera EP20K100TC144-2 is a Field Programmable Gate Array (FPGA) belonging to the APEX 20K family. It features 4160 Logic Elements and 416 Logic Array Blocks, providing substantial programmable logic density for complex digital designs. The device integrates 52 kbit of embedded memory, supporting data storage and FIFO implementations within the fabric. It operates at a maximum frequency of 180 MHz and utilizes a single 2.5 V power supply. The component is housed in a TQFP-144 surface-mount package with 92 I/O pins, designed for high-performance applications requiring reliable programmable logic capabilities.

Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Availability is restricted to existing stock or third-party distributors. Verification of authenticity and lot traceability is critical due to the discontinued status. Buyers should confirm the specific speed grade suffix and package condition before acquisition, as no new production units are manufactured.

Selection Notes

Select this model when 4160 LEs and 180 MHz performance meet design requirements within a 144-pin form factor. Ensure the design supports the 2.5 V core voltage. For newer projects, consider migrating to modern FPGA families with enhanced I/O standards and lower power consumption, as legacy support tools may have limited availability.

Part Context

The EP20K100TC144-2 is part of the APEX 20K series, which introduced System-on-a-Programmable-Chip integration. This family combined Look-Up Table logic with embedded memory blocks, offering higher density than previous CPLD generations. It served as a bridge between complex PLDs and early FPGAs, widely used in telecommunications and networking infrastructure during its active production period.

Replacement Considerations

No direct pin-compatible replacements exist within the same family due to EOL status. Alternative solutions require redesigning the PCB layout to accommodate different packages and pinouts from successor FPGA families such as Cyclone or Arria series.
