66AK2H06BAAW2

Overview

The Texas Instruments 66AK2H06BAAW2 is a KeyStone II System-on-Chip featuring four TMS320C66x DSP cores and two 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 Packet and Security Accelerators, and peripherals such as USB 3.0, PCIe Gen2, and a five-port Ethernet switch. It is housed in a 1517-pin AAW package.

Feature Summary

• Quad-core ARM Cortex-A15 MPCore cluster operating at up to 1.4 GHz

• Integrated Network Coprocessor supporting IPsec, GTP-U, and SSL/TLS
• Sixteen 64-bit timers and 32 GPIO pins

Applications

• Mission Critical Systems
• Cloud Computing Infrastructure
• Media Processing and Transcoding
• High-Performance Computing
• Security Appliances

Procurement Notes

Verify the specific ordering suffix 'B' against official documentation to confirm manufacturing lot or revision details. Confirm availability status directly with Texas Instruments or authorized distributors, as production data may indicate limited supply or end-of-life conditions for this specific variant.

Selection Notes

Select the 66AK2H06 over higher-end models like the 66AK2H12 or 66AK2H14 when only four DSP cores and two ARM cores are required. This model lacks the 10-Gigabit Ethernet subsystem found in the 66AK2H14. Ensure the application fits within the 6 MB MSMC SRAM capacity and requires the specific peripheral mix available on the 66AK2H06.

Part Context

This component belongs to the 66AK2Hxx family of multicore DSP+ARM KeyStone II SoCs. It shares the same 0.028 µm process technology and 1517-pin AAW package as the 66AK2H12 and 66AK2H14. The primary differentiation lies in the number of active DSP and ARM cores, as well as the presence or absence of the 10-GbE interface.

Replacement Considerations

Direct functional replacements within the same package include the 66AK2H12 and 66AK2H14, provided the additional cores and memory resources are acceptable. Verify that the software architecture can utilize the extra resources or that the pinout compatibility remains intact across the family.
