EP20K100TC144-3N

Overview

The Altera EP20K100TC144-3N 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-based macrocells, and embedded system blocks (ESBs). The device provides 4,160 logic elements, 416 macrocells, and 53,248 maximum RAM bits. It operates at a supply voltage of 2.5 V with an I/O range of 2.5 V, 3.3 V, or 5.0 V. 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 logic for register-intensive functions and product-term logic for combinatorial paths.
• Embedded System Blocks (ESBs) supporting dual-port RAM, FIFO buffers, and content-addressable memory (CAM).
• Flexible clock management with up to four phase-locked loops (PLLs) and ClockLock/ClockBoost features.
• MultiVolt I/O interface supporting 1.8-V, 2.5-V, 3.3-V, and 5.0-V standards.

Applications

• System-on-a-programmable-chip (SOPC) integration designs.
• Complex state machines requiring high-speed control logic.
• Digital signal processing (DSP) and mathematical data-path applications.
• PCI Local Bus Specification compliant interfaces.

Procurement Notes

Verify component authenticity through authorized distributors as this part may be end-of-life. Confirm RoHS compliance status and moisture sensitivity levels prior to procurement. Ensure storage conditions meet JEDDEC standards to prevent damage before reflow soldering.

Selection Notes

Select this model for designs requiring mixed LUT and product-term logic within a 144-pin TQFP footprint. Verify that the 2.5 V internal supply voltage aligns with the target power budget. Check if the 92 available user I/O pins satisfy the interface requirements compared to other pin counts in the APEX 20K series.

Part Context

This device is part of the APEX 20K family, which introduced the MultiCore architecture to Altera's programmable logic portfolio. It serves as a bridge between traditional CPLDs and high-density FPGAs, offering significant logic density and embedded memory capabilities for its time.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consider modern Intel/Altera FPGA families such as Cyclone or Arria for new designs, ensuring pinout and logic resource compatibility during migration.

FAQ

What is the difference between the EP20K100 and EP20K100E?

The EP20K100E is part of the APEX 20KE superset, offering enhanced features such as support for 1.8-V I/O, CAM, additional global clocks, and advanced clock circuitry compared to the standard EP20K100.

How does the MultiCore architecture benefit design efficiency?

It integrates LUT-based logic for efficient data-path handling with product-term-based logic for complex state machines, allowing both types of functions to coexist efficiently on a single die without excessive routing overhead.

What is the function of the Embedded System Block (ESB)?

The ESB implements memory functions including dual-port RAM, FIFO buffers, ROM, and Content-Addressable Memory (CAM), providing high-speed access without reducing available logic resources.
