66AK2H12BAAWA2

Overview

The Texas Instruments 66AK2H12BAAWA2 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 controllers supporting speeds up to 1600 MHz, and a network coprocessor with packet acceleration and security engines. Peripherals include USB 3.0, PCIe Gen2, Serial RapidIO, and a five-port Gigabit Ethernet switch. It is housed in a 1517-pin flip-chip plastic BGA (AAW) package.

Feature Summary

• Eight C66x DSP cores providing up to 9.6 GHz total processing capability
• Four ARM Cortex-A15 MPCore processors with 4 MB shared L2 cache
• Integrated Network Coprocessor with Packet Accelerator and Security Engine
• Dual 72-bit DDR3/DDR3L interfaces supporting up to 1600 MHz

Applications

• Cloud computing infrastructure
• High-performance media processing and transcoding
• Virtual desktop infrastructure
• Network security appliances

Procurement Notes

Verify the specific suffix 'B' against official documentation to confirm manufacturing grade or revision details. Ensure compatibility with the EVMK2H development environment for software validation. Confirm power supply requirements match the SmartReflex variable core voltage specifications.

Selection Notes

Select this model over the 66AK2H14 if the 10-Gigabit Ethernet subsystem is not required. Compare against the 66AK2H06 if fewer DSP cores are sufficient for the workload. Verify that the 1517-pin AAW package footprint matches the target PCB design constraints.

Part Context

This component belongs to the 66AK2Hxx family, which includes the 66AK2H14 and 66AK2H06 variants. These devices share the same KeyStone II architecture and physical package but differ in core counts and peripheral availability. The 66AK2H12 serves as an intermediate option between the higher-end 66AK2H14 and the lower-cost 66AK2H06.

Replacement Considerations

Direct functional replacements within the same package include the 66AK2H14AAXAW24 and 66AK2H06AAAWA2. Note that pinouts may vary due to reserved pins for unused peripherals like the 10GbE interface.
