EP20K100ETC144-2

Overview

The Altera EP20K100ETC144-2 is a Field Programmable Gate Array (FPGA) belonging to the APEX 20K family. It features a MultiCore architecture integrating Look-Up Table (LUT) logic, product-term logic, and Embedded System Blocks (ESB). The device provides 4,160 Logic Elements (LEs), 53,248 bits of embedded RAM, and 416 macrocells. It operates at a maximum system frequency of 180 MHz with a 2.5 V supply voltage. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package and supports up to 92 user I/O pins.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions with 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 four phase-locked loops (PLLs) and ClockLock technology for reduced skew.
• Support for MultiVolt I/O standards including 2.5 V, 3.3 V, and 5.0 V interfaces.

Applications

• System-on-a-programmable-chip (SOPC) integration designs.
• Complex state machines and control logic implementation.
• High-speed arithmetic functions such as adders and counters using dedicated carry chains.
• Digital signal processing (DSP) data-path applications.

Procurement Notes

Verify the specific speed grade suffix (-2) against the manufacturer's datasheet to confirm timing characteristics. Confirm that the TQFP-144 package matches the design footprint requirements. Check for moisture sensitivity levels and reflow soldering profiles appropriate for the thin quad flat pack format.

Selection Notes

Select this model when a combination of high-density logic (4,160 LEs) and embedded memory is required within a 144-pin form factor. Ensure the design utilizes the 2.5 V internal supply voltage. Consider the -2 speed grade if the target application requires a maximum operating frequency of 180 MHz.

Part Context

This component is part of the APEX 20K family, which was designed as one of the first PLDs to incorporate SOPC integration capabilities. The 'E' suffix indicates Enhanced features, while 'TC' denotes the TQFP package type. The '-2' suffix specifies the performance speed grade relative to other variants in the EP20K100 series.

Replacement Considerations

Direct replacements within the same family include the EP20K100ETC144-1 or EP20K100ETC144-3, depending on whether higher or lower speed grades are acceptable. Verify pinout compatibility and electrical specifications before substitution.
