EP20K1000CF672C9

Overview

The Altera EP20K1000CF672C9 is a high-density Field Programmable Gate Array (FPGA) belonging to the APEX 20KC family. It features a MultiCore architecture integrating look-up table (LUT) logic and embedded system blocks (ESBs). The device provides up to 38,400 logic elements (LEs), 160 ESBs, and a maximum of 327,680 RAM bits. It operates at an internal supply voltage of 1.8 V and supports MultiVolt I/O interfaces for 1.8-V, 2.5-V, and 3.3-V levels. Manufactured using a 0.15-µm all-layer copper-metal process, it offers enhanced performance over previous generations.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions with product-term-based logic for complex combinatorial paths.
• Embedded System Blocks (ESBs) supporting memory functions including FIFO buffers, dual-port RAM, and content-addressable memory (CAM).
• Advanced clock management with up to four phase-locked loops (PLLs), ClockLock, ClockBoost, and ClockShift features.
• Comprehensive I/O support including LVDS, LVPECL, PCI-X, AGP, SSTL-2/3, GTL+, and HSTL standards.

Applications

• System-on-a-programmable-chip (SOPC) designs requiring integration of logic, control, and memory.
• High-speed data path and digital signal processing (DSP) applications utilizing LUT efficiency.
• Complex state machine implementations optimized by product-term-based logic.
• Interfaces compliant with PCI Local Bus Specification Revision 2.2.

Procurement Notes

This component is listed as discontinued or end-of-life in public distributor records. Verification of current availability requires checking authorized channels for remaining stock or obsolescence notices. Designers should confirm lead times and sourcing options carefully due to the mature status of the APEX 20KC family.

Selection Notes

Select this device for applications requiring high I/O counts (up to 708 user pins in larger packages) and significant embedded memory resources. Ensure compatibility with the 1.8 V core voltage and verify that the target design fits within the 38,400 LE capacity. Consider the FBGA-672 package dimensions and pitch when designing the PCB footprint.

Part Context

The EP20K1000C variant represents the highest density option in the base APEX 20KC series before the introduction of larger devices like the EP20K1500C. It shares pin compatibility with the APEX 20KE family, facilitating potential migration from older technologies while leveraging the speed improvements of the copper interconnect process.

Replacement Considerations

Public documentation indicates that newer Altera families such as Stratix, Cyclone, or Arria are recommended replacements for legacy APEX devices. Specific pin-compatible or functionally equivalent modern part numbers are not explicitly listed in the provided source material; consult official migration guides for detailed cross-references.
