EP20K160EQI240-3

Overview

The EP20K160EQI240-3 is a high-density programmable logic device from the Altera APEX 20KE family, utilizing the MultiCore architecture. It integrates look-up table (LUT) logic, product-term-based macrocells, and embedded system blocks (ESBs) for memory functions. This specific variant features 6,400 logic elements, 40 ESBs providing up to 81,920 RAM bits, and 640 maximum macrocells. It supports 316 user I/O pins within a 240-pin RQFP package. The device operates with a 1.8-V internal supply voltage and supports MultiVolt I/O levels including 1.8-V, 2.5-V, 3.3-V, and 5.0-V via external resistor tolerance.

Feature Summary

• MultiCore architecture combining LUT logic, product-term logic, and embedded memory in a single die.
• High density with 6,400 logic elements and 81,920 maximum RAM bits available without reducing logic capacity.
• Support for advanced I/O standards including LVDS, PCI-X, AGP, SSTL, and GTL+.
• Flexible clock management with four phase-locked loops (PLLs), ClockLock, and ClockBoost features.

Applications

• System-on-a-programmable-chip (SOPC) integration designs.
• Complex state machines requiring combinatorial-intensive product-term logic.
• Register-intensive data-path and digital signal processing (DSP) applications.
• Interfaces supporting high-speed external memories such as DDR SDRAM and ZBT SRAM.

Procurement Notes

Verify the ordering suffix 'E' confirms APEX 20KE features, specifically 5.0-V I/O tolerance when used with an external resistor. Confirm the 'I' suffix corresponds to the industrial temperature range and the '240' indicates the 240-pin RQFP package. Ensure compatibility with the Quartus II development system for configuration and design entry.

Selection Notes

Select this model for designs requiring a mix of register-intensive LUT logic and complex combinatorial paths. The EP20K160E offers sufficient embedded memory for FIFO, dual-port RAM, or CAM implementations. Consider the 1.8-V core voltage for low-power operation and verify that the 240-pin RQFP package fits the board space constraints compared to BGA options.

Part Context

This component belongs to the APEX 20KE series, which extends the original APEX 20K family with enhanced features like additional global clocks, CAM support, and broader I/O standard compliance. The 'E' suffix distinguishes it from non-E variants by offering MultiVolt I/O flexibility and advanced clocking capabilities suitable for high-performance system integration.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. Designers should consult Altera's official obsolescence notices or cross-reference tools for equivalent devices within the APEX 20K or subsequent Cyclone/Stratix families if availability is required.
