EP20K160EFC144-2

Overview

The Altera EP20K160EFC144-2 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), 81,920 maximum RAM bits, and 640 macrocells. It operates at a supply voltage of 1.8 V with support for MultiVolt I/O standards including 1.8-V, 2.5-V, 3.3-V, and 5.0-V levels. The component is housed in a 144-pin FineLine BGA package and supports a maximum system frequency of 180 MHz.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term logic for combinatorial paths.
• 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 enabling compatibility with 1.8-V, 2.5-V, 3.3-V, and 5.0-V devices.

Applications

• System-on-a-programmable-chip (SOPC) integration designs.
• High-speed external memory interfaces including DDR SDRAM and ZBT SRAM.
• PCI Local Bus Specification compliant systems (3.3-V operation at 33 or 66 MHz).
• Complex state machines and arithmetic functions utilizing dedicated carry and cascade chains.

Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Designers should confirm RoHS compliance status, as indicated by 'N' in some listings, and review Product Change Notifications (PCN) for discontinuance details before procurement.

Selection Notes

Select the EP20K160EFC144-2 for applications requiring 6,400 LEs and 1.8-V core voltage. Ensure the design utilizes the 144-pin FineLine BGA package constraints. Verify that the required I/O standards are supported by the 1.8-V MultiVolt interface. Consider the -2 speed grade if the target frequency exceeds 180 MHz, noting that higher speed grades may offer improved timing performance.

Part Context

The EP20K160EFC144-2 is part of the APEX 20KE series, which extends the original APEX 20K family with enhanced features such as additional global clocks, CAM support, and advanced I/O standards. It represents a transition point in Altera's programmable logic portfolio, offering high-density integration before the introduction of subsequent families like Stratix.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, designers should evaluate modern FPGA families from Intel/Altera or other vendors for pin-compatible or functionally equivalent replacements.
