EP20K100EQI240-2X

Overview

The EP20K100EQI240-2X is an APEX 20K series Field Programmable Gate Array (FPGA) manufactured by Altera. It features a MultiCore architecture integrating Look-Up Table (LUT) logic, product-term logic, and Embedded System Blocks (ESBs). The device provides 4,160 Logic Elements (LEs), 416 macrocells, and 53,248 maximum RAM bits. It operates at a 2.5 V internal supply voltage with support for 2.5 V, 3.3 V, or 5.0 V I/O levels via the MultiVolt interface. Packaged in a 240-pin Plastic Quad Flat Package (PQFP), it supports high-speed interfaces including PCI Local Bus Specification Revision 2.2.

Feature Summary

• MultiCore Architecture: Combines LUT-based logic for register-intensive functions with product-term logic for combinatorial paths and ESBs for memory implementation.
• High Density Resources: Includes 4,160 LEs, 416 macrocells, and up to 53,248 RAM bits without reducing available logic capacity.
• Flexible Clock Management: Features four phase-locked loops (PLLs), a built-in low-skew clock tree, and ClockLock/ClockBoost circuitry.
• Advanced I/O Standards: Supports MultiVolt I/O (1.8V/2.5V/3.3V/5.0V), LVDS, PCI-X, AGP, and compliance with PCI Local Bus Rev 2.2.

Applications

• System-on-a-programmable-chip (SOPC) integration
• PCI Local Bus interface design
• High-speed cryptographic accelerators
• Complex state machine implementation

Procurement Notes

Verify component authenticity through authorized distributors or original manufacturer channels. Confirm RoHS compliance status as indicated on the specific datasheet revision. Check for End-of-Life (EOL) notifications from Altera/Intel prior to procurement planning.

Selection Notes

Select this model for designs requiring mixed LUT and product-term logic efficiency. Ensure PCB layout accommodates the 240-pin PQFP package dimensions. Verify that the target application voltage requirements align with the supported MultiVolt I/O levels of 2.5 V, 3.3 V, or 5.0 V.

Part Context

This component belongs to the APEX 20K family, representing Altera's first PLD incorporating SOPC integration. It succeeded earlier FLEX and MAX families, offering higher density and advanced memory structures like CAM and dual-port RAM within a single die.

Replacement Considerations

No direct public substitute part numbers are listed in the provided documentation. Consider Intel/Altera Cyclone or Arria series for modern replacements, subject to architectural compatibility verification.
