EP20K100ETI144-3

Overview

The Altera EP20K100ETI144-3 is a Field Programmable Gate Array (FPGA) belonging to the APEX 20K family. It features 4,160 Logic Elements (LEs), 416 macrocells, and 53,248 bits of embedded memory. The device operates at a maximum system frequency of 170 MHz with a 2.5 V internal supply voltage. It utilizes a MultiCore architecture integrating LUT logic, product-term logic, and Embedded System Blocks (ESBs). The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term-based logic for combinatorial paths.
• Embedded System Blocks (ESBs) 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.
• Support for high-speed I/O standards including PCI Local Bus Specification Revision 2.2.

Applications

• System-on-a-programmable-chip (SOPC) integration designs.
• Complex state machines requiring combinatorial-intensive logic.
• Digital signal processing (DSP) and data-path applications.
• High-speed external memory interfaces such as DDR SDRAM.

Procurement Notes

Verify the specific speed grade suffix (-3) against official datasheets, as standard listings often reference -1 or -2 grades. Confirm availability status, as this legacy component may be discontinued. Ensure design tools support the APEX 20K family for compilation and configuration.

Selection Notes

Select this model for designs requiring a balance of LUT flexibility and product-term efficiency. Compare resource requirements against the EP20K100E variant if lower power consumption via 1.8V operation is needed. Verify pin count compatibility with the 144-pin TQFP footprint.

Part Context

This part belongs to the APEX 20K series, which was among the first PLDs to incorporate SOPC integration. The family distinguishes between standard APEX 20K devices and the enhanced APEX 20KE series, which offers additional I/O standards and memory features like CAM.

Replacement Considerations

No direct public substitutes are listed. Consider Intel/Altera Cyclone or Stratix families for modern replacements, though architectural differences require full design re-evaluation.

FAQ

What is the internal supply voltage for the EP20K100ETI144-3?

The internal supply voltage (VCCINT) is 2.5 V.

How many Embedded System Blocks (ESBs) does this device contain?

The EP20K100 device contains 26 ESBs.

Does this device support Content-Addressable Memory (CAM)?

Standard APEX 20K devices do not explicitly list CAM support in Table 8; CAM is primarily associated with the APEX 20KE series.
