EP20K400EFC672-3N

Field Programmable Gate Array Overview

The Altera EP20K400EFC672-3N 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 16,640 logic elements (LEs), 104 ESBs, and supports up to 488 user I/O pins in a 672-pin FineLine BGA package. 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. Key specifications include a maximum system gate count of 1,052,000 and a typical gate count of 400,000.

Field Programmable Gate Array Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term-based logic for combinatorial-intensive tasks.
• Embedded System Blocks (ESBs) supporting FIFO buffers, dual-port RAM, and content-addressable memory (CAM).
• Advanced clock management with four phase-locked loops (PLLs), ClockLock, ClockBoost, and ClockShift features.
• Support for high-speed I/O standards including LVDS, PCI-X, AGP, SSTL-2/3, HSTL Class I, and GTL+.

Field Programmable Gate Array Applications

• System-on-a-programmable-chip (SOPC) integration designs.
• Complex state machines and control logic requiring product-term optimization.
• High-speed data-path and digital signal processing (DSP) applications.
• Interfaces compliant with PCI Local Bus Specification Revision 2.2.

Field Programmable Gate Array Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence notices. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure design files are compatible with the Quartus II development system version supporting the APEX 20KE family.

Field Programmable Gate Array Selection Notes

Select the EP20K400E over the standard EP20K400 for enhanced I/O standard support and additional global clock resources. Verify that the 1.8-V internal core voltage aligns with the target board's power delivery network. Ensure sufficient ESB capacity for required memory configurations such as CAM or dual-port RAM implementations.

Field Programmable Gate Array 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 broader I/O standard compatibility. It utilizes the MegaLAB structure containing Logic Array Blocks (LABs) and Embedded System Blocks (ESBs) interconnected by the FastTrack Interconnect.
