EP20K100EFC324-3N

Overview

The Altera EP20K100EFC324-3N 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, 416 macrocells, and 53,248 bits of embedded memory. It operates at an internal supply voltage (VCCINT) of 2.5 V with MultiVolt I/O support for 1.8 V, 2.5 V, 3.3 V, and 5.0 V levels. Packaged in a 324-pin FineLine BGA, it supports up to 246 user I/O pins and includes four phase-locked loops for clock management.

Feature Summary

• MultiCore architecture combining LUT logic, product-term logic, and embedded memory within a single die.
• High-density configuration with 4,160 LEs, 416 macrocells, and 53,248 RAM bits.
• MultiVolt I/O interface supporting 1.8-V, 2.5-V, 3.3-V, and 5.0-V signaling standards.
• Advanced clock management featuring four PLLs, ClockLock, and ClockBoost capabilities.

Applications

• Implementation of hash function processors for IPSEC applications such as VPNs.
• Complex state machines requiring combinatorial-intensive product-term logic.
• Register-intensive digital signal processing (DSP) and data-path functions.
• PCI Local Bus Specification compliant interfaces operating at 33 or 66 MHz.

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to soldering. Check for end-of-life notifications or discontinuance alerts from Altera/Intel. Ensure design files are compatible with legacy Quartus II software versions supporting the APEX 20K family.

Selection Notes

Select this model when designs require a mix of register-intensive and complex combinatorial logic. The EP20K100E offers higher I/O count (246) compared to the non-E variant (252) but adds advanced I/O standards like LVDS and PCI-X. Verify package availability in 324-pin FineLine BGA. Consider power requirements for 2.5 V core voltage and selected I/O banks.

Part Context

The EP20K100E is part of the APEX 20KE series, which extends the original APEX 20K family with enhanced features. It shares the same logic density as the EP20K100 but includes additional I/O standards and clock resources. This device represents a mature programmable logic solution before the transition to Stratix and Cyclone families.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Legacy migration typically involves evaluating Intel/Altera Cyclone III or IV FPGAs for similar logic densities and I/O counts. Consult official obsolescence notices for recommended replacement paths.
