EP20K100EQC208-3

Overview

The Altera EP20K100EQC208-3N 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), 26 ESBs, and 53,248 maximum RAM bits. It operates at a supply voltage of 1.8 V for internal logic and supports MultiVolt I/O levels including 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The component is housed in a 208-pin QFP package with 151 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 (ESB) supporting FIFO buffers, dual-port RAM, and content-addressable memory (CAM).
• Flexible clock management with up to four phase-locked loops (PLLs) and ClockLock/ClockBoost features.
• MultiVolt I/O interface supporting 1.8-V, 2.5-V, 3.3-V, and 5.0-V devices.

Applications

• System-on-a-programmable-chip (SOPC) designs requiring integration of logic, control, and memory.
• Complex state machines and combinatorial-intensive functions utilizing product-term logic.
• Digital signal processing (DSP) and data-path applications optimized by LUT-based logic.
• Interfaces compliant with PCI Local Bus Specification Revision 2.2.

Procurement Notes

Verify the specific suffix '3' against official datasheets to confirm the speed grade and temperature range. Confirm RoHS compliance status as manufacturing sources may vary. Check for end-of-life or obsolescence notices from Intel/Altera distributors before procurement planning.

Selection Notes

Select this model for designs requiring 4,160 LEs and 1.8-V core voltage operation. Ensure the application utilizes the 151 available I/O pins within the 208-pin QFP footprint. Compare against EP20K100E if 2.5-V operation is preferred, noting that the 'E' suffix denotes the enhanced feature set.

Part Context

This component is part of the APEX 20K family, which was among the first PLDs to incorporate SOPC integration. The 'E' suffix indicates it belongs to the APEX 20KE subset, offering advanced I/O standards like LVDS and additional global clocks compared to standard APEX 20K devices.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider reviewing the EP20K100E variant for 2.5-V operation or consulting current Intel FPGA portfolios for modern equivalents.
