EP20K100TC144-1

Overview

The Altera EP20K100TC144-1 is a Field Programmable Gate Array (FPGA) belonging to the APEX 20K device family. It features a MultiCore architecture integrating look-up table (LUT) logic, product-term logic, and embedded system blocks (ESBs). The device provides 4,160 logic elements (LEs), 53,248 maximum RAM bits, and 416 macrocells. It operates at a supply voltage of 2.5 V with an I/O interface supporting 2.5 V, 3.3 V, or 5.0 V levels. The component is housed in a 144-pin Thin Quad Flat Pack (TQFP) package and supports a maximum system frequency of 180 MHz.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions with product-term logic for combinatorial paths.
• Embedded System Blocks (ESBs) support memory functions including FIFO buffers, dual-port RAM, and content-addressable memory (CAM).
• Flexible clock management with up to four phase-locked loops (PLLs), ClockLock, and 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.
• Complex state machines requiring high-speed control logic.
• Digital signal processing (DSP) and mathematical applications.
• PCI Local Bus Specification compliant interfaces.

Procurement Notes

Verify the specific speed grade suffix (-1) against design timing requirements, as performance varies across grades. Confirm RoHS compliance status through official manufacturer documentation, as historical data may vary. Ensure the TQFP-144 package dimensions match the target PCB footprint. Check for end-of-life notifications or obsolescence notices from Altera/Intel prior to procurement.

Selection Notes

Select this model for designs requiring 4,160 LEs and significant embedded memory within a 144-pin form factor. Compare against EP20K100E variants if 1.8-V internal supply or enhanced I/O standards like LVDS are required. Verify that the 2.5-V core voltage aligns with the system power budget. Consider pin count limitations compared to larger packages like QFP-208 if more I/O is needed.

Part Context

The EP20K100TC144-1 is part of the original APEX 20K family, distinct from the later APEX 20KE series which offers additional features like 1.8-V operation and expanded I/O standards. It utilizes the MegaLAB structure containing Logic Array Blocks (LABs) and Embedded System Blocks (ESBs). The 'T' indicates the TQFP package, while '144' denotes the pin count.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Designers should consult Intel/Altera migration guides for modern FPGA families such as Cyclone or Agilex for functional equivalents.
