EP20K100ETC144-3

Overview

The Altera EP20K100ETC144-3 is an APEX 20KE Field Programmable Gate Array (FPGA) housed in a 144-pin Thin Quad Flat Pack (TQFP). It features the MultiCore architecture, integrating Look-Up Table (LUT) logic, product-term logic, and Embedded System Blocks (ESBs). The device provides 4,160 Logic Elements (LEs), 416 macrocells, and 53,248 bits of embedded RAM. It operates at a maximum system frequency of 170 MHz with a 2.5 V internal supply voltage (VCCINT). The I/O interface supports multiple voltage levels including 2.5 V, 3.3 V, and 5.0 V via the MultiVolt feature.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term logic for combinatorial paths.
• Embedded System Blocks (ESBs) supporting FIFO, 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 allowing operation 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 data-path and digital signal processing (DSP) applications.
• Complex state machines requiring combinatorial-intensive logic.
• PCI Local Bus compliant interfaces operating at 33 or 66 MHz.

Procurement Notes

Verify component authenticity as this part number is from a legacy family. Confirm the -3 speed grade corresponds to the 170 MHz performance tier specified in the datasheet. Ensure the TQFP-144 package matches the design footprint requirements. Check for moisture sensitivity handling procedures prior to assembly.

Selection Notes

Select this model when 4,160 LEs and 53 kbit memory are required within a 144-pin TQFP package. The -3 speed grade offers 170 MHz performance. Consider the EP20K100E variants if different pin counts or packages like FBGA are needed. Verify that the 2.5 V core voltage aligns with the board's power delivery infrastructure.

Part Context

This component belongs to the APEX 20KE family, which extends the original APEX 20K series with enhanced I/O standards and additional global clocks. The 'E' suffix denotes support for advanced features like LVDS and PCI-X. The EP20K100E variant specifically targets mid-density applications requiring high performance and flexible memory configurations.

Replacement Considerations

No direct public substitutes are listed. Legacy replacements may include other APEX 20K devices with similar LE counts but different packages or speed grades. Modern Intel Agilex or Cyclone families require architectural redesign due to differences in logic structure and I/O standards.
