66AK2H12DXAAWA24

Overview

The Texas Instruments 66AK2H12DXAAWA24 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 packet acceleration and security engines. Peripheral connectivity includes USB 3.0, PCIe Gen2, Serial RapidIO, and a five-port Gigabit Ethernet switch.

Feature Summary

• Eight C66x DSP cores (up to 1.2 GHz) and four ARM Cortex-A15 cores (up to 1.4 GHz)
• KeyStone II architecture with Multicore Navigator and Network Coprocessor
• Dual 72-bit DDR3/DDR3L EMIFs supporting up to 1600 MHz
• Integrated Security Accelerator and Packet Accelerator

Applications

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

Procurement Notes

Verify the specific suffix 'D' in the part number against official documentation to confirm performance grade or revision details. Ensure compatibility with the EVMK2H development environment for software validation. Confirm moisture sensitivity handling requirements during assembly.

Selection Notes

Select this model when eight DSP cores are required alongside four ARM application processors. Compare against the 66AK2H14 if ten-gigabit Ethernet support is necessary, as the 66AK2H12 lacks the 10-GbE subsystem. Verify that the 1517-pin AAW package fits the target PCB layout constraints.

Part Context

This component belongs to the 66AK2Hxx family, which also includes the 66AK2H14 and 66AK2H06. The 66AK2H12 serves as an intermediate option between the 66AK2H14 (which adds 10-GbE) and the 66AK2H06 (which reduces core counts). All variants share the same physical package and base architecture.

Replacement Considerations

The 66AK2H14AXAAW24 offers identical processing capabilities but includes additional 10-Gigabit Ethernet ports. The 66AK2H06 provides reduced core counts (four DSPs, two ARM cores) within the same package.
