EP20K100QC240-3

Overview

The Altera EP20K100QC240-3 is a Field Programmable Gate Array (FPGA) belonging to the APEX 20K family. 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), 53,248 maximum RAM bits, and 416 macrocells. It operates at an internal supply voltage of 2.5 V with MultiVolt I/O support for 2.5 V, 3.3 V, and 5.0 V levels. The component is housed in a 240-pin Plastic Quad Flat Pack (PQFP) package and supports up to 246 user I/O pins.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term logic for combinatorial paths.
• Embedded System Blocks (ESBs) supporting dual-port RAM, FIFO, CAM, and ROM implementations.
• Flexible clock management with four phase-locked loops (PLLs), ClockLock, and ClockBoost features.
• FastTrack Interconnect structure with dedicated carry and cascade chains for high-speed arithmetic and wide fan-in logic.

Applications

• System-on-a-programmable-chip (SOPC) integration designs.
• Complex state machines and control logic requiring product-term optimization.
• Digital signal processing (DSP) and mathematical data-path applications.
• PCI Local Bus Specification compliant interfaces (3.3-V operation).

Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to lifecycle restrictions. Confirm package integrity and moisture sensitivity handling procedures prior to assembly. Cross-reference ordering suffixes to ensure correct speed grade and temperature range specifications match design requirements.

Selection Notes

Select the EP20K100QC240-3 for designs requiring a balance of logic density and embedded memory within a QFP package. Ensure power supply rails are stable at 2.5 V for VCCINT. Verify that the 240-pin PQFP footprint aligns with PCB layout constraints. Consider the -3 speed grade timing characteristics against system clock requirements.

Part Context

This device is part of the APEX 20K family, which was among the first PLDs to incorporate SOPC integration capabilities. The EP20K100 variant specifically targets mid-range density applications, offering 263,000 maximum system gates. It is supported by the Quartus II development system for design entry, synthesis, and place-and-route operations.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Legacy replacements or modern equivalents should be evaluated based on pin compatibility and logic resource equivalence using Intel's FPGA migration tools.
