EP20K100EFC324-2N

Overview

The Altera EP20K100EFC324-2N 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 (ESB). The device provides 4,160 Logic Elements (LEs), 53,248 maximum RAM bits, and 416 macrocells. It supports a 2.5 V internal supply voltage with MultiVolt I/O capabilities for 1.8 V, 2.5 V, 3.3 V, and 5.0 V interfaces. Packaged in a 324-pin FineLine BGA, it operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term logic for combinatorial paths.
• Embedded System Blocks (ESB) supporting FIFO buffers, 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 supporting 1.8-V, 2.5-V, 3.3-V, and 5.0-V devices.

Applications

• High-speed cryptographic accelerators for IPSEC applications such as VPNs.
• System-on-a-programmable-chip (SOPC) designs requiring integrated logic and memory.
• Complex state machines and digital signal processing (DSP) implementations.

Procurement Notes

Verify component authenticity through authorized distributors or original manufacturer channels. Confirm package integrity and pin alignment against the 324-pin FineLine BGA specification. Ensure storage conditions comply with moisture sensitivity levels prior to soldering. Cross-reference the specific speed grade suffix to confirm timing characteristics match design requirements.

Selection Notes

Select this model when designs require a mix of high-density logic and embedded memory structures. The EP20K100E variant offers enhanced I/O standards compared to the standard EP20K100, including support for LVDS and PCI-X. Verify that the 324-pin FBGA footprint fits the PCB layout constraints and that the 2.5 V core voltage aligns with the system power budget.

Part Context

This component is part of the APEX 20KE series, which extends the original APEX 20K family with advanced features like CAM support and additional global clocks. The 'E' suffix denotes the Enhanced version with broader I/O standard compatibility. The FC324 designation indicates the FineLine BGA package with 324 balls.

Replacement Considerations

Direct functional replacements within the same density and package are limited due to the legacy status of the APEX 20K family. Consider upgrading to newer Intel/Altera FPGA families such as Cyclone or Stratix for modern manufacturing support, ensuring pinout and resource mapping are re-evaluated.
