EP20K100EQC240-2X

Overview

The EP20K100EQC240-2X is an APEX 20KE Field Programmable Gate Array (FPGA) from Altera, utilizing the MultiCore architecture. It features a 2.5-V internal supply voltage and supports 3.3-V I/O levels. The device provides 4,160 logic elements, 26 Embedded System Blocks (ESBs), and up to 53,248 RAM bits. It is housed in a 240-pin Plastic Quad Flat Package (PQFP) with a 0.50 mm pitch. The component includes four phase-locked loops for clock management and supports advanced I/O standards such as PCI-X and LVDS.

Feature Summary

• MultiCore architecture integrating LUT logic, product-term logic, and Embedded System Blocks (ESBs).
• Supports 3.3-V PCI and PCI-X standards with full compliance in -2 speed grades.
• Includes four PLLs with ClockLock and ClockShift capabilities for flexible clock management.
• Features FastTrack Interconnect with dedicated carry and cascade chains for high-speed arithmetic.

Applications

• Complex state machine implementations requiring combinatorial-intensive logic.
• Digital signal processing (DSP) designs utilizing register-intensive functions.
• System-on-a-programmable-chip (SOPC) integration projects.
• High-speed interface designs supporting PCI-X and LVDS standards.

Procurement Notes

Verify the specific ordering suffix 'X' against official documentation, as standard datasheets may not explicitly detail its functional impact. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for End-of-Life (EOL) notifications or Product Change Notifications (PCNs) relevant to this specific revision.

Selection Notes

Select this device for applications requiring a mix of register-intensive and combinatorial logic within a single chip. Ensure the design fits within the 4,160 LE and 53,248-bit memory constraints. Verify that the 240-pin PQFP package meets board space requirements and that the 2.5-V core voltage aligns with system power rails.

Part Context

This part belongs to the APEX 20KE family, which extends the standard APEX 20K series with enhanced features like additional global clocks and support for more I/O standards. The 'E' suffix denotes the Enhanced variant, while 'QC' indicates the 240-pin QFP package type. It is designed for high-density programmable logic applications.

Replacement Considerations

Consult Altera's legacy device support page for recommended transitions. Modern alternatives include Cyclone V or Arria 10 families. Verify pinout compatibility and logic density equivalence when migrating to newer FPGA architectures.
