EP20K100QC240-3N

Overview

The Altera EP20K100QC240-3N is a Field Programmable Gate Array (FPGA) belonging to the APEX 20K family. It features 4,160 logic elements and 53,248 bits of embedded RAM within an FPGA architecture. The device operates at a maximum system frequency of 180 MHz and supports a 2.5 V internal supply voltage. It utilizes a MultiCore architecture integrating look-up table logic, product-term logic, and embedded memory. The component is housed in a 240-pin Plastic Quad Flat Package (PQFP) with a 0.50 mm pitch.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term logic for combinatorial-intensive tasks.
• Embedded System Blocks (ESBs) providing up to 53,248 bits of RAM, FIFO buffers, dual-port RAM, and content-addressable memory.
• Flexible clock management with built-in low-skew clock tree and support for global clock signals.
• I/O compliance with PCI Local Bus Specification Revision 2.2 for 3.3-V operation.

Applications

• Complex state machine implementations requiring high-speed combinatorial logic.
• Digital signal processing (DSP) designs utilizing LUT-based arithmetic functions.
• System-on-a-programmable-chip (SOPC) integration projects.
• High-density programmable logic applications replacing multiple discrete components.

Procurement Notes

Verify component authenticity through authorized channels as this part may be discontinued. Confirm package integrity and moisture sensitivity handling procedures prior to assembly. Ensure design files are compatible with legacy development tools such as Quartus II for compilation and configuration.

Selection Notes

Select this model when 4,160 logic elements and 246 user I/O pins are required in a QFP package. Compare against EP20K100E variants if 1.8 V operation or enhanced I/O standards like LVDS are needed. Verify that the 2.5 V internal supply voltage aligns with the target system power rails.

Part Context

This component is part of the Altera APEX 20K family, which was among the first PLDs to integrate SOPC capabilities. The EP20K100 variant specifically offers a balance of logic density and I/O count. It serves as a bridge between traditional CPLDs and higher-end FPGAs, supporting reconfigurable computing applications via serial or parallel configuration interfaces.

Replacement Considerations

Direct pin-to-pin replacements are not publicly documented for this specific speed grade and package combination. Consider EP20K100E series devices for functional equivalence with potential voltage differences. Modern architectural equivalents require significant design migration due to differences in logic block structures and interconnect architectures.
