66AK2H14DAAW24

Overview

The Texas Instruments 66AK2H14DAAW24 is a multicore system-on-chip based on the KeyStone II architecture. It integrates eight TMS320C66x DSP cores operating at up to 1.2 GHz and four ARM Cortex-A15 processors running at up to 1.4 GHz. The device includes 6 MB of shared MSMC SRAM, dual 72-bit DDR3/DDR3L memory interfaces supporting speeds up to 1600 MHz, and a network coprocessor with a five-port Ethernet switch and two XFI ports for 10-Gigabit Ethernet. Additional peripherals include USB 3.0, PCIe Gen2, Serial RapidIO, and HyperLink interfaces.

Feature Summary

• Eight C66x DSP cores providing up to 9.6 GHz total processing capability
• Four ARM Cortex-A15 MPCore processors with 4 MB shared L2 cache
• Integrated network coprocessor with packet accelerator and security engine
• Dual 72-bit DDR3/DDR3L EMIFs supporting up to 1600 MHz

Applications

• Cloud computing infrastructure
• High-performance media processing and transcoding
• Network security and virtual desktop environments
• Analytics and gaming platforms

Procurement Notes

Verify the specific suffix 'W24' against official documentation to confirm package type and temperature range specifications. Ensure compatibility with the EVMK2H development ecosystem for software validation. Confirm that the required power supply rails match the SmartReflex variable core voltage and specified I/O levels.

Selection Notes

Select this model when eight DSP cores and dedicated 10-Gigabit Ethernet capabilities are required. Compare against the 66AK2H12 or 66AK2H06 variants if fewer processor cores or the absence of 10GbE ports align better with the design constraints. Verify thermal management requirements for the extended case temperature range.

Part Context

This component belongs to the 66AK2Hxx family of KeyStone II System-on-Chips. It shares the same physical package dimensions (40 mm x 40 mm) and pinout as the 66AK2H12 and 66AK2H06 models. The primary distinction lies in the number of active DSP cores and the inclusion of the 10-GbE subsystem.

Replacement Considerations

The 66AK2H12AAXAW24 serves as a functional substitute within the same package, offering identical ARM cores but only seven C66x DSP cores and lacking the 10-Gigabit Ethernet interface.
