EP20K100EQC240-3

Overview

The Altera EP20K100EQC240-3 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 (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 1.8 V with MultiVolt I/O support for 1.8-V, 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 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-intensive applications.
• Embedded System Blocks (ESBs) supporting dual-port RAM, FIFO buffers, and content-addressable memory (CAM).
• Flexible clock management with up to 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

• System-on-a-programmable-chip (SOPC) integration designs.
• Complex state machines and control logic requiring high-speed combinatorial paths.
• Digital signal processing (DSP) and arithmetic functions utilizing dedicated carry chains.
• High-density memory implementations using ESBs for CAM or dual-port RAM.

Procurement Notes

Verify the specific ordering suffix 'E' confirms the APEX 20KE variant with 1.8-V core voltage and enhanced I/O standards. Confirm the '-3' speed grade matches the required timing constraints. Check RoHS compliance status as historical data may vary. Ensure the 240-pin PQFP package footprint aligns with the target PCB design.

Selection Notes

Select this model when designs require a mix of register-intensive LUT logic and complex combinatorial product-term structures. The 1.8-V core voltage offers lower power consumption compared to 2.5-V variants. Verify that the 240-pin QFP package provides sufficient I/O count (up to 246 pins) for the application. Consider the -3 speed grade for specific frequency requirements within the commercial temperature range.

Part Context

This component is part of the APEX 20KE series, which extends the original APEX 20K family with advanced features like 1.8-V operation and additional I/O standards. The 'EP20K100' designation indicates 4,160 LEs and 53,248 RAM bits. The 'QC' suffix denotes the 240-pin PQFP package type. The 'E' suffix distinguishes it from the standard APEX 20K by including 1.8-V core voltage support.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official replacement guides or consider newer FPGA families for long-term availability.
