EP20K100QC240-1

Overview

The EP20K100QC240-1 is an APEX 20K field-programmable gate array featuring a MultiCore architecture that integrates look-up table logic, product-term logic, and embedded system blocks. It provides 4,160 logic elements, 416 macrocells, and 53,248 RAM bits within a 240-pin plastic quad flat package. The device operates at a maximum frequency of 180 MHz with a 2.5 V internal supply voltage and supports MultiVolt I/O standards for 2.5 V, 3.3 V, or 5.0 V interfaces.

Feature Summary

• MultiCore architecture combining LUT logic, product-term logic, and embedded memory
• 4,160 logic elements and 416 product-term-based macrocells
• 53,248 bits of embedded RAM without reducing logic capacity
• MultiVolt I/O interface supporting 2.5 V, 3.3 V, and 5.0 V levels

Applications

• System-on-a-programmable-chip integration
• PCI Local Bus Specification compliant designs
• High-speed external memory interfaces including DDR SDRAM
• Complex state machines and register-intensive functions

Procurement Notes

Verify the specific ordering suffix to confirm package type and speed grade. Confirm RoHS compliance status as older revisions may differ. Check for end-of-life notifications from Altera or Intel, as this component belongs to a legacy family. Ensure design tools support the APEX 20K architecture for compilation.

Selection Notes

Select based on required logic density, specifically the 4,160 LE count. Verify I/O voltage requirements against the MultiVolt capability. Consider the 240-pin QFP package constraints for board layout. Compare against EP20K100E variants if 1.8 V operation or enhanced clock features are needed.

Part Context

This part belongs to the APEX 20K family, which introduced the MultiCore architecture. It sits between the EP20K60E and EP20K160E in terms of logic resources. The QC240 designation indicates a 240-pin PQFP package. The -1 suffix denotes the fastest speed grade available for this device.

Replacement Considerations

Direct pin-compatible replacements are not available due to architectural differences. Consider EP20K100E for similar functionality with different power options. Modern alternatives include Stratix or Cyclone families, though these require significant redesign.
