EP20K100QI208-2

Overview

The EP20K100QI208-2 is a Field Programmable Gate Array (FPGA) belonging to the APEX 20K family manufactured by Altera. 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), 416 macrocells, and 53,248 maximum RAM bits. It operates at a 2.5 V internal supply voltage with support for 2.5 V, 3.3 V, and 5.0 V I/O levels. The component is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package and supports industrial temperature ranges.

Feature Summary

• MultiCore architecture combining LUT-based logic, product-term-based logic, and embedded memory.
• High-density logic resources including 4,160 LEs and 416 macrocells.
• Flexible clock management with up to four phase-locked loops (PLLs) and ClockLock feature.
• MultiVolt I/O interface supporting 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 and combinatorial-intensive functions.
• Register-intensive data-path and digital signal processing (DSP) applications.
• PCI Local Bus Specification compliant interfaces.

Procurement Notes

Verify the specific ordering suffix 'QI' against official documentation to confirm package type and temperature grade. Confirm end-of-life status and availability through authorized channels, as this component may be discontinued or subject to limited supply constraints.

Selection Notes

Select this model for designs requiring a mix of register-intensive and complex combinatorial logic within a single chip. Ensure the design fits within the 4,160 LE and 53,248-bit memory limits. Verify that the 208-pin PQFP package dimensions are compatible with the target PCB layout and that the 2.5 V core voltage aligns with the system power budget.

Part Context

This part is an enhanced version within the APEX 20K family, which was among the first PLDs to incorporate SOPC integration capabilities. The APEX 20K series utilizes a FastTrack Interconnect structure for predictable delays and supports advanced packaging options including FineLine BGA and QFP variants.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided source material. Consider reviewing Intel/Altera's subsequent FPGA families for modern equivalents if new production is required.
