EP20K100EFC324-2

Overview

The Altera EP20K100EFC324-2 is a Field Programmable Gate Array (FPGA) belonging to the APEX 20KE 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 supports up to 246 user I/O pins and operates at an internal supply voltage of 2.5 V with MultiVolt I/O support for 1.8-V, 2.5-V, 3.3-V, and 5.0-V levels. The component is housed in a 324-pin FineLine BGA package.

Feature Summary

• MultiCore architecture combining LUT-based logic, product-term-based logic, and embedded memory within a single die.
• Supports advanced I/O standards including LVDS, LVPECL, PCI-X, AGP, CTT, GTL+, SSTL-2, SSTL-3, and HSTL Class I.
• Integrated clock management with four phase-locked loops (PLLs), ClockLock, ClockBoost, and ClockShift features.
• Embedded IEEE Std. 1149.1 JTAG boundary-scan circuitry for testing and configuration.

Applications

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

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and humidity sensitivity handling requirements prior to assembly. Check for end-of-life notifications or discontinuance notices from Altera/Intel. Ensure design tools are compatible with the specific speed grade and package variant.

Selection Notes

Select this model when high-density logic (4,160 LEs) and extensive embedded memory (53 kbit) are required in a 324-pin form factor. Choose the -2 speed grade if timing constraints allow for lower performance than the -1 grade. Ensure the design utilizes the 2.5 V core voltage and compatible I/O standards supported by the APEX 20KE family.

Part Context

This device is part of the APEX 20KE series, which extends the standard APEX 20K family with enhanced features like additional global clocks and broader I/O standard support. It represents a generation of programmable logic designed for complex system integration before subsequent families like Stratix and Cyclone were introduced.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Legacy replacements may require architectural migration to newer Intel FPGA families such as Cyclone or Arria, necessitating design re-verification.
