66AK2H12DAAW2

Overview

The Texas Instruments 66AK2H12DAAW2 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 security acceleration, and peripherals such as USB 3.0, PCIe Gen2, and a five-port Ethernet switch. The device is housed in a 1517-pin FCBGA package.

Procurement Notes

Verify the specific suffix '2' against official documentation to confirm frequency binning or voltage specifications. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly. Ensure compliance with export control regulations regarding enabled security accelerator functions.

Selection Notes

Select this model for applications requiring high throughput in packet processing and multimedia transcoding. Compare core counts and memory sizes against the 66AK2H14 and 66AK2H06 variants to match system requirements. Verify peripheral availability, noting that the 10-GbE ports are reserved on this specific device variant.

Part Context

This component belongs to the 66AK2Hxx family of multicore DSP+ARM SoCs. It utilizes the KeyStone II architecture to integrate processor clusters with high-speed interconnects. The device shares the same physical package dimensions and pinout compatibility with other members of the series, differing primarily in core count and peripheral configuration.

Replacement Considerations

Direct replacements within the same package include the 66AK2H14 and 66AK2H06. Verify functional differences, specifically the presence of 10-GbE ports on the 66AK2H14 and reduced core counts on the 66AK2H06.
