EP20K100EFC324-2X

Overview

The Altera EP20K100EFC324-2X is a Field Programmable Gate Array (FPGA) belonging to the APEX 20KE family. It features a MultiCore architecture integrating Look-Up Table (LUT) logic, product-term logic, and Embedded System Blocks (ESB). The device provides 4,160 Logic Elements (LEs), 53,248 maximum RAM bits, and 416 macrocells. It operates at a 2.5 V internal supply voltage with MultiVolt I/O support for 1.8 V, 2.5 V, 3.3 V, and 5.0 V levels. Packaged in a 324-pin FineLine BGA, it supports up to 246 user I/O pins and includes four phase-locked loops (PLLs) for clock management.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term logic for combinatorial paths.
• Embedded System Blocks (ESB) supporting FIFO, dual-port RAM, ROM, and Content-Addressable Memory (CAM).
• Flexible clock management with four PLLs, ClockLock, ClockBoost, and ClockShift features.
• MultiVolt I/O interface enabling compatibility with 1.8-V, 2.5-V, 3.3-V, and 5.0-V devices.

Applications

• High-speed cryptographic accelerators for IPSEC applications such as VPNs.
• Complex state machines requiring high-speed control logic.
• Digital signal processing (DSP) designs utilizing LUT-based data paths.
• PCI Local Bus interfaces compliant with Revision 2.2 specifications.

Procurement Notes

Verify component authenticity through authorized distributors or original manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to soldering. Check for end-of-life notifications as this part may be discontinued. Ensure proper handling of humidity-sensitive devices according to JEDDEC standards during storage and assembly.

Selection Notes

Select the EP20K100E variant over the standard EP20K100 for enhanced I/O standards including LVDS, PCI-X, and SSTL. Verify that the 324-pin FBGA package meets board space constraints. Ensure design requirements align with the 2.5 V core voltage and available I/O voltage levels. Consider the -2 speed grade timing characteristics for system clock frequencies.

Part Context

This component is part of the APEX 20KE programmable logic device family by Altera. It represents an evolution of the APEX 20K series, adding advanced features like CAM support and additional global clocks. The 'E' suffix denotes the Enhanced version with broader I/O standard support compared to the base EP20K100 model.

Replacement Considerations
