66AK2H14DXAAWA24

Overview

The 66AK2H14DXAAWA24 is a KeyStone II System-on-Chip featuring eight TMS320C66x DSP cores and four ARM Cortex-A15 processors. The C66x cores operate at up to 1.2 GHz, delivering 38.4 GMACs/core for fixed-point and 19.2 GFlops/core for floating-point processing. The ARM cores run at up to 1.4 GHz with 4 MB of shared L2 cache. It includes 6 MB of MSMC SRAM, a Network Coprocessor with Packet and Security Accelerators, and peripherals such as USB 3.0, PCIe Gen2, and a 10-GbE switch subsystem.

Feature Summary

• Eight C66x DSP cores (up to 1.2 GHz) and four ARM Cortex-A15 cores (up to 1.4 GHz)
• Network Coprocessor supporting IPsec, GTP-U, and SSL/TLS security acceleration
• Integrated 10-Gigabit Ethernet switch subsystem with two XFI ports
• Multicore Navigator with 16k hardware queues and packet-based DMA

Applications

• Mission Critical Systems
• Cloud Computing Infrastructure
• High-Performance Media Processing
• Security Gateways

Procurement Notes

Verify the specific suffix 'D' against official documentation to confirm the commercial temperature range (0°C to 85°C). Ensure the ordering code matches the exact package dimensions and pin configuration required for the target PCB layout.

Selection Notes

Select this model when high-throughput packet processing and cryptographic acceleration are required alongside general-purpose computing. The 10-GbE interface distinguishes it from lower-tier variants like the 66AK2H12 or 66AK2H06. Verify power supply requirements for the SmartReflex variable core voltage and multiple I/O voltage domains.

Part Context

This component belongs to the 66AK2Hxx family within the Texas Instruments KeyStone II architecture portfolio. It represents the highest-performance variant in the series due to its inclusion of the 10-GbE switch subsystem and full complement of eight DSP cores.

Replacement Considerations

Direct replacements include other 66AK2H14 variants with different thermal grades or memory configurations. Cross-model substitution with 66AK2H12 or 66AK2H06 requires hardware redesign due to missing 10-GbE ports and reduced core counts.
