EP20K100EQC240-3N

Overview

The EP20K100EQC240-3N is an APEX 20KE programmable logic device from Altera, housed in a 240-pin PQFP package. It features the MultiCore architecture integrating LUT and product-term logic with embedded system blocks (ESBs). Key electrical parameters include a 1.8-V internal supply voltage (VCCINT) and support for 1.8-V, 2.5-V, 3.3-V, and 5.0-V I/O levels via MultiVolt technology. The device provides 4,160 logic elements, 26 ESBs, and up to 53,248 maximum RAM bits. It operates within a commercial temperature range of 0°C to +70°C.

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 without reducing logic capacity.
• Flexible clock management with four phase-locked loops (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

• Digital IF processing systems requiring high-speed data shifting and filtering.
• PCI Local Bus applications compliant with Revision 2.2 specifications.
• High-density system-on-a-programmable-chip designs integrating complex state machines and memory functions.

Procurement Notes

Verify component authenticity through authorized channels as this part may be end-of-life. Confirm RoHS compliance status and moisture sensitivity level prior to soldering. Ensure proper handling procedures are followed due to humidity sensitivity requirements specified in the datasheet.

Selection Notes

Select this model for designs requiring 4,160 LEs and extensive embedded memory capabilities. The 1.8-V core voltage necessitates appropriate power supply design. Verify that the 240-pin QFP package fits the board layout constraints and thermal requirements for the 0°C to +70°C operating range.

Part Context

This component belongs to the APEX 20KE family, which extends the standard APEX 20K series with enhanced features like LVDS support and additional global clocks. It represents a high-performance PLD solution designed for complex digital logic integration before the widespread adoption of modern FPGA architectures.
