EP20K100EFI144-2X

Overview

The Altera EP20K100EFI144-2X is a Field Programmable Gate Array (FPGA) belonging to the APEX 20KE family. It features the MultiCore architecture, integrating Look-Up Table (LUT) logic, product-term macrocells, and Embedded System Blocks (ESB). The device provides 4,160 Logic Elements (LEs), 416 macrocells, and 53,248 bits of embedded RAM. It operates at a maximum system frequency of 200 MHz with a 2.5 V internal supply voltage. The component is housed in a 144-pin FineLine BGA package and supports up to 93 user I/O pins.

Feature Summary

• MultiCore Architecture: Combines LUT-based logic for register-intensive functions with product-term logic for combinatorial paths.
• Embedded Memory: Includes 53,248 bits of ESB memory supporting FIFO, dual-port RAM, and CAM implementations.
• Clock Management: Features four phase-locked loops (PLLs) and ClockLock technology for low-skew clock distribution.
• High-Speed I/O: Supports MultiVolt interfaces (1.8V, 2.5V, 3.3V, 5.0V) and standards including LVDS, PCI-X, and SSTL.

Applications

• System-on-a-programmable-chip (SOPC) integration
• Complex state machine implementation
• Digital signal processing (DSP) data paths
• PCI Local Bus interface design

Procurement Notes

This component is an obsolete part from the Altera APEX 20KE family. Verification should focus on confirming the specific -2 speed grade and EFI144 package variant against legacy datasheets. Availability is limited to surplus or secondary markets; original manufacturer support is discontinued.

Selection Notes

Select this device for designs requiring high-density programmable logic with mixed LUT and product-term capabilities. The -2 speed grade indicates a 200 MHz maximum frequency. Ensure the design utilizes the 2.5 V core voltage and compatible I/O standards supported by the APEX 20KE series.

Part Context

The EP20K100EFI144-2X is part of the APEX 20KE series, which extends the standard APEX 20K family with enhanced I/O standards and additional global clocks. The 'E' suffix denotes the Enhanced version, while 'FI' specifies the FineLine BGA package type. This generation preceded the Stratix and Cyclone families.

Replacement Considerations

No direct pin-compatible replacements exist within current Intel/Altera portfolios. Modern equivalents such as the Cyclone 10 LP or Agilex series require significant PCB redesign and software migration. Legacy stock must be sourced from authorized distributors or certified surplus vendors.

FAQ
