66AK2H12BAAW2

Overview

The Texas Instruments 66AK2H12BAAW2 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 features 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. Peripheral connectivity includes USB 3.0, PCIe Gen2, Serial RapidIO, HyperLink, and multiple serial interfaces.

Feature Summary

• Eight C66x DSP cores providing 38.4 GMACS/core fixed-point performance at 1.2 GHz
• Four ARM Cortex-A15 MPCore processors with 4 MB shared L2 cache
• Network coprocessor with packet accelerator and security engine for IPsec and SSL/TLS
• Dual 72-bit DDR3/DDR3L EMIFs supporting up to 1600 MHz data rates

Applications

• Cloud computing infrastructure
• High-performance media processing and transcoding
• Virtual desktop infrastructure
• Security appliances and analytics

Procurement Notes

Verify the specific suffix 'B' against official documentation to confirm manufacturing lot or revision details. Ensure compatibility with the EVMK2H development platform if prototyping. Confirm RoHS compliance status through the manufacturer's current datasheet revision.

Selection Notes

Select this model when eight DSP cores are required alongside an ARM application processor. Compare against the 66AK2H14 for additional 10-GbE ports or the 66AK2H06 for reduced core counts. Verify that the 1517-pin FCBGA package fits the target PCB layout constraints.

Part Context

This component belongs to the 66AK2Hxx family, which also includes the 66AK2H14 and 66AK2H06. All variants share the same 0.028 µm process technology and 1517-pin AAW package. Differences primarily involve the number of DSP cores, ARM cores, and specific peripheral availability such as the 10-GbE switch.

Replacement Considerations

The 66AK2H14A serves as a functional upgrade within the same package offering more peripherals. The 66AK2H06 provides a lower-core alternative. Cross-model substitution requires verification of pin compatibility and software migration efforts.
