66AK2H14DAAWA24

Overview

The Texas Instruments 66AK2H14DAAWA24 is a KeyStone II System-on-Chip integrating 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. The device includes 6 MB of MSMC SRAM, a Network Coprocessor with security acceleration, and a 10-Gigabit Ethernet switch subsystem. It utilizes a 1517-pin FCBGA package.

Feature Summary

• Eight C66x DSP cores (up to 1.2 GHz) and four ARM Cortex-A15 cores (up to 1.4 GHz)
• Integrated Network Coprocessor supporting IPsec, SSL/TLS, and packet acceleration
• 10-Gigabit Ethernet Switch Subsystem with two XFI ports and IEEE 1588 support
• Multicore Navigator with 16k hardware queues and Packet DMA

Applications

• Mission Critical Infrastructure
• Cloud Computing and High-Performance Computing
• Media Processing and Transcoding
• Security Gateways and Analytics

Procurement Notes

Verify the specific suffix 'DAAWA24' against the manufacturer's current orderable part list to confirm availability and revision status. Ensure environmental ratings match the required operating temperature range, as commercial and extended variants exist within this family.

Selection Notes

Select this model when high-throughput packet processing and cryptographic acceleration are required alongside general-purpose computing. The 10GbE capability distinguishes it from lower-tier models like the 66AK2H06 or 66AK2H12. Confirm that the 1517-pin BGA footprint fits the target PCB design constraints.

Part Context

This component belongs to the 66AK2Hxx series of multicore DSP+ARM SoCs based on the KeyStone II architecture. It represents the highest-performance variant in the standard lineup due to its inclusion of the 10-GbE switch and full complement of eight DSP cores.

Replacement Considerations

Direct functional replacements within the same package include the 66AK2H12 and 66AK2H06, though these lack the 10-Gigabit Ethernet subsystem and have fewer DSP cores.
