EP20K100QI240-2

Overview

The Altera EP20K100QI240-2 is a Field Programmable Gate Array (FPGA) belonging to the APEX 20K family. It features 4,160 Logic Elements (LEs), 53,248 embedded RAM bits, and 416 macrocells. The device operates at a maximum system frequency of 170 MHz with a 2.5 V supply voltage. It is housed in a 240-pin Plastic Quad Flat Package (PQFP). This component utilizes the MultiCore architecture, integrating LUT logic, product-term logic, and Embedded System Blocks (ESBs) for high-density system-on-a-programmable-chip integration.

Feature Summary

• MultiCore architecture combining LUT-based logic, product-term logic, and embedded memory.
• 4,160 Logic Elements and 53,248 embedded RAM bits.
• Supports up to four phase-locked loops (PLLs) for flexible clock management.
• Compliant with PCI Local Bus Specification Revision 2.2.

Applications

• High-speed cryptographic accelerators for IPSEC applications.
• Complex state machines requiring combinatorial-intensive functions.
• Register-intensive digital signal processing (DSP) designs.

Procurement Notes

Verify component authenticity through authorized channels as this part may be discontinued. Confirm package integrity and pin alignment for the 240-pin PQFP form factor. Ensure design compatibility with legacy Altera development tools such as Quartus II software versions supporting the APEX 20K family.

Selection Notes

Select this model when 4,160 LEs and 240-pin QFP packaging are required. Compare against EP20K100 variants with different speed grades or package types if higher frequencies or alternative footprints are needed. Verify that the 2.5 V internal supply voltage aligns with system power requirements.

Part Context

This device is part of the APEX 20K series, representing early system-on-a-programmable-chip technology. It succeeded earlier FLEX families and introduced the MultiCore architecture. The EP20K100 variant specifically targets mid-range density applications within this lineage.

Replacement Considerations

Direct replacements are limited due to the discontinued status of the APEX 20K family. Consider modern Intel/Altera FPGA families such as Cyclone or Arria series, noting significant architectural differences in logic blocks and I/O standards.

FAQ
