EP20K400EFC672-1X

Field Programmable Gate Array Overview

The EP20K400EFC672-1X is an APEX 20KE Field Programmable Gate Array (FPGA) from Altera, utilizing the MultiCore architecture. It features a 1.8 V internal supply voltage and supports MultiVolt I/O standards including 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The device provides 16,640 logic elements, 104 Embedded System Blocks (ESBs), and up to 212,992 RAM bits. It operates at a maximum system frequency of 170 MHz within a commercial temperature range of 0°C to +70°C. Packaged in a 672-pin FineLine BGA, it integrates LUT logic, product-term logic, and embedded memory for system-on-a-programmable-chip applications.

Field Programmable Gate Array Feature Summary

• MultiCore architecture combining LUT-based logic, product-term-based logic, and Embedded System Blocks (ESBs).
• Supports MultiVolt I/O interface with 1.8 V, 2.5 V, 3.3 V, and 5.0 V levels.
• Includes ClockLock and ClockBoost clock management circuitry with dedicated global clocks.
• Features FastTrack Interconnect with dedicated carry and cascade chains for high-speed arithmetic.

Field Programmable Gate Array Applications

• System-on-a-programmable-chip (SOPC) integration designs.
• Complex state machines requiring combinatorial-intensive functions.
• Register-intensive data-path and digital signal processing (DSP) applications.
• Implementations of FIFO buffers, dual-port RAM, and content-addressable memory (CAM).

Field Programmable Gate Array Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct manufacturer distribution. Confirm RoHS compliance status and humidity sensitivity handling requirements prior to procurement, as the device is moisture sensitive.

Field Programmable Gate Array Selection Notes

Select this device for designs requiring high-density logic with mixed LUT and product-term capabilities. Ensure the design utilizes the 1.8 V core voltage and compatible I/O standards. Verify that the 672-pin FBGA package fits the board space constraints. Consider the 170 MHz speed grade if timing closure at higher frequencies is required.

Field Programmable Gate Array Part Context

The EP20K400E belongs to the APEX 20KE family, which extends the standard APEX 20K series with enhanced I/O support and lower power options. It shares the same MegaLAB structure and FastTrack Interconnect as other devices in the family but offers specific resource counts tailored for mid-to-high density applications.

Field Programmable Gate Array Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers may need to evaluate newer Altera/Intel FPGA families for functional equivalents, considering architectural differences and pin compatibility.
