EP20K400EFC672-3

Field Programmable Gate Array Overview

The Altera EP20K400EFC672-3 is a Field Programmable Gate Array (FPGA) belonging to the APEX 20K device family. It features a MultiCore architecture integrating look-up table (LUT) logic, product-term logic, and embedded system blocks (ESBs). The device provides 16,640 logic elements (LEs), 1,664 macrocells, and 212,992 RAM bits. It operates at a maximum system frequency of 170 MHz with a 2.5 V internal supply voltage (VCCINT). The component is housed in a 672-pin FineLine BGA package and supports an operating temperature range from 0°C to +70°C.

Field Programmable Gate Array Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term logic for combinatorial-intensive tasks.
• Embedded System Blocks (ESBs) supporting FIFO buffers, dual-port RAM, and content-addressable memory (CAM).
• Flexible clock management with up to four phase-locked loops (PLLs) and ClockLock technology for reduced skew.
• MultiVolt I/O interface supporting 2.5 V, 3.3 V, and 5.0 V levels for compatibility with diverse peripheral devices.

Field Programmable Gate Array Applications

• System-on-a-programmable-chip (SOPC) integration requiring mixed logic and memory resources.
• High-speed data processing and digital signal processing (DSP) applications utilizing LUT efficiency.
• Complex state machine implementations optimized by product-term-based logic structures.
• PCI Local Bus compliant interfaces operating at 33 or 66 MHz.

Field Programmable Gate Array Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Verification of authenticity is critical when sourcing from secondary markets due to discontinuation status. Buyers should confirm the specific -3 speed grade and FC672 package variant against original datasheet specifications to ensure functional equivalence for legacy designs.

Field Programmable Gate Array Selection Notes

Select this model for designs requiring high-density programmable logic within the APEX 20K ecosystem. The -3 suffix indicates a 170 MHz speed grade, suitable for moderate-to-high frequency applications. Ensure board design guidelines account for the 2.5 V core voltage and the specific thermal requirements of the 672-pin FineLine BGA package during PCB layout.

Field Programmable Gate Array Part Context

The EP20K400EFC672-3 is part of the broader APEX 20K family, which introduced SOPC capabilities to programmable logic. It sits between the lower-density EP20K200 and higher-density EP20K600 models in terms of logic capacity. This specific part number represents the enhanced 'E' variant, offering expanded I/O standards and memory features compared to standard APEX 20K devices.

Field Programmable Gate Array Replacement Considerations

No direct public substitute part numbers are documented for this discontinued component. Legacy designs may require migration to newer Intel FPGA families such as Cyclone or Stratix, necessitating significant architectural redesign and software toolchain updates.
