EP20K160EFC484-3

Overview

The EP20K160EFC484-3 is an Altera APEX 20KE Field Programmable Gate Array featuring the MultiCore architecture. It integrates look-up table logic, product-term macrocells, and Embedded System Blocks (ESBs) for memory functions. The device provides 6,400 Logic Elements, 640 macrocells, and 81,920 RAM bits. It operates at a maximum system frequency of 180 MHz with a 1.8-V internal supply voltage. Packaged in a 484-pin FineLine BGA, it supports up to 316 user I/O pins and includes four phase-locked loops for clock management.

Feature Summary

• MultiCore architecture combining LUT logic, product-term macrocells, and ESBs for SOPC integration
• 6,400 Logic Elements and 640 product-term-based macrocells
• 81,920 embedded RAM bits supporting FIFO, dual-port RAM, and CAM
• Four PLLs with ClockLock and ClockBoost features for flexible clock management

Applications

• Complex state machine implementations utilizing product-term logic
• Register-intensive data-path and DSP functions using LUT logic
• High-density memory applications requiring embedded SRAM or CAM
• PCI Local Bus and high-speed interface designs compliant with PCI SIG specifications

Procurement Notes

This component is from the APEX 20K family, which has reached end-of-life status. Verification of authenticity is critical when sourcing from secondary markets. Ensure compatibility with legacy configuration devices such as the EPC series for serial programming. Designers should confirm that the 1.8-V supply requirements align with existing system power rails before procurement.

Selection Notes

Select this device for designs requiring a mix of combinatorial efficiency and register density. The -3 speed grade indicates a 180 MHz maximum operating frequency. Verify that the 484-pin FBGA package fits the board space constraints. Consider the 1.8-V core voltage requirement for power budgeting and ensure appropriate level shifting if interfacing with 3.3-V or 5.0-V peripherals via the MultiVolt I/O capability.

Part Context

The EP20K160E belongs to the APEX 20KE sub-family, which extends the standard APEX 20K features with enhanced I/O standards like LVDS and PCI-X support. The 'E' suffix denotes these advanced interface capabilities. The FC484 designation specifies the 484-pin FineLine BGA package with a 1.00 mm pitch. This part represents a mid-range density solution within the 160,000 typical gate category.

Replacement Considerations

No direct pin-compatible replacements are documented in public sources. Legacy designs may migrate to Stratix or Cyclone families, but these require significant schematic and software redesign due to architectural differences.
