EP20K160EFC484-3AA

Overview

The Altera EP20K160EFC484-3AA 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 6,400 Logic Elements (LEs), 40 ESBs, and supports up to 81,920 RAM bits. It operates with a 2.5 V internal supply voltage and includes an embedded IEEE Std. 1149.1 JTAG boundary-scan circuitry. The component utilizes a 484-pin FineLine BGA package.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term logic for combinatorial-intensive tasks.
• 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) integration designs.
• Complex state machines and digital signal processing (DSP) applications.
• High-speed external memory interfaces including DDR SDRAM and ZBT SRAM.
• PCI Local Bus Specification compliant systems operating at 33 or 66 MHz.

Procurement Notes

Verify the specific suffix 'AA' against official documentation, as standard datasheets typically list '-3'. Confirm RoHS compliance status, as earlier APEX 20K variants were non-compliant. Check for End-of-Life (EOL) notifications from Intel/Altera, as this family is legacy. Ensure sourcing from authorized distributors due to potential obsolescence.

Selection Notes

Select the EP20K160E variant when 6,400 LEs and 81,920 RAM bits are required within a 484-pin footprint. Choose the -3 speed grade if timing requirements align with its specifications. Consider the APEX 20KE series for enhanced I/O standards like LVDS and PCI-X compared to the base APEX 20K. Verify power supply compatibility with the 2.5 V VCCINT requirement.

Part Context

This component is part of the APEX 20KE family, which extends the original APEX 20K line with advanced features such as CAM support, additional global clocks, and enhanced clock circuitry. The 'E' suffix denotes the Enhanced version. The EP20K160E sits between the EP20K100E and EP20K200E in terms of logic density and I/O count within the 484-pin package options.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided source material. Legacy FPGA families often require redesign rather than pin-to-pin replacement. Consult Intel's migration guides for modern FPGAs such as the Cyclone or Arria series for functional equivalents.
