EP20K100EQC240-1X

Overview

The EP20K100EQC240-1X is an Altera APEX 20K field-programmable gate array featuring the MultiCore architecture. It integrates look-up table logic, product-term logic, and embedded system blocks (ESBs). The device provides 4,160 logic elements, 53,248 maximum RAM bits, and 416 macrocells. It operates at a 2.5 V internal supply voltage with MultiVolt I/O support for 2.5 V, 3.3 V, or 5.0 V levels. Packaged in a 240-pin plastic quad flat pack, it supports a maximum system frequency of 180 MHz.

Feature Summary

• MultiCore architecture combining LUT logic, product-term logic, and embedded memory
• 4,160 logic elements and 53,248 maximum RAM bits
• MultiVolt I/O interface supporting 2.5 V, 3.3 V, and 5.0 V standards
• Four-level hierarchical FastTrack Interconnect structure

Applications

• System-on-a-programmable-chip integration
• PCI Local Bus Specification compliant designs
• High-speed external memory interfaces
• Complex state machine implementations

Procurement Notes

This component is from the APEX 20K family, which is listed as discontinued in official product lifecycle collections. Verification of current availability requires checking authorized distributors for remaining stock or end-of-life notifications. Ensure compatibility with legacy design tools such as Quartus II.

Selection Notes

Select this model for designs requiring a mix of register-intensive and combinatorial logic within a single chip. The -1 speed grade indicates a maximum operating frequency of 180 MHz. Verify that the 240-pin QFP package fits the board layout constraints and that the 2.5 V core voltage aligns with the power delivery network.

Part Context

The EP20K100EQC240-1X belongs to the APEX 20K series, representing early SOPC integration capabilities. It sits between the smaller EP20K60E and larger EP20K160E in terms of logic density. The 'E' suffix denotes enhanced features compared to standard APEX 20K devices, including broader I/O standard support.

Replacement Considerations

Official replacement options include other APEX 20K variants like the EP20K100ETC144-1N for different pin counts or the EP20K100QC208-1 for alternative packaging. Modern equivalents are found in the Cyclone or Stratix families, though architectural differences require design migration.
