EP20K100EFC144-2

Overview

The Altera EP20K100EFC144-2 is a Field Programmable Gate Array (FPGA) belonging to the APEX 20K family. It features 4160 Logic Elements and 52 kbit of embedded memory, organized into 416 Logic Array Blocks (LABs). The device operates at a maximum frequency of 170 MHz with a supply voltage of 2.5 V. It provides 92 I/O pins and is housed in a 144-pin FineLine BGA package. Designed for surface mount installation, it supports an operating temperature range from 0°C to +70°C.

Feature Summary

• APEX 20K architecture integrating Look-Up Table logic, product-term logic, and Embedded System Blocks
• 4160 Logic Elements distributed across 416 LABs for complex logic implementation
• 52 kbit embedded memory supporting FIFO buffers and dual-port RAM functions
• 170 MHz maximum operating frequency with 2.5 V core voltage

Applications

• Industrial control systems requiring deterministic logic processing
• Legacy equipment maintenance and replacement for obsolete programmable logic
• Signal processing interfaces in measurement instrumentation

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Verification should focus on confirming the authenticity of available stock, checking for original packaging integrity, and validating traceability records. Buyers must account for potential availability constraints and verify that the specific revision matches legacy design requirements without modification.

Selection Notes

Select this part when migrating or repairing designs based on the APEX 20K family. Ensure the PCB footprint matches the FC144 (FineLine BGA) package dimensions. Verify that the system power supply strictly maintains the 2.5 V requirement. Consider the 170 MHz speed grade if timing closure is critical for the target application logic.

Part Context

The EP20K100EFC144-2 is part of the APEX 20K series, which introduced System-on-a-Programmable-Chip (SOPC) integration capabilities. This specific model represents the 100K variant within the family, offering a balance of logic density and I/O count suitable for mid-range programmable logic applications before being superseded by newer Cyclone and Stratix families.

Replacement Considerations

No direct pin-compatible replacements are publicly documented for this EOL part. Migration typically requires redesigning the PCB and updating the configuration bitstream for newer FPGA families such as the Cyclone IV or Arria series.
