66AK2H12BXAAW2

Overview

The Texas Instruments 66AK2H12BXAAW2 is a Multicore DSP+ARM KeyStone II System-on-Chip (SoC). 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 6MB of shared MSMC SRAM, dual 72-bit DDR3/DDR3L memory controllers supporting speeds up to 1600 MHz, and a comprehensive peripheral set including USB 3.0, PCIe Gen2, Serial RapidIO, and a five-port Gigabit Ethernet switch. It utilizes a 1517-pin FCBGA package.

Feature Summary

• Eight C66x DSP cores providing up to 9.6 GHz total DSP processing power
• Four ARM Cortex-A15 MPCore processors with up to 5.6 GHz total ARM processing power
• Integrated Network Coprocessor with Packet Accelerator and Security Accelerator
• Dual 72-bit DDR3/DDR3L EMIF interfaces for high-bandwidth external memory access

Applications

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

Procurement Notes

Verify the specific suffix 'BX' against the official datasheet to confirm manufacturing lot or revision details. Ensure the design supports the required SmartReflex variable core voltage and multiple I/O voltage domains ranging from 0.85 V to 3.3 V. Confirm humidity sensitivity handling during assembly as indicated in the packaging specifications.

Selection Notes

Select this model over the 66AK2H14 if the ten-gigabit Ethernet (XFI) ports are not required, as they are reserved on the 66AK2H12. Choose between the 66AK2H12 and 66AK2H06 based on the need for eight versus four DSP cores. Ensure the application can utilize the KeyStone II architecture's multicore navigator and cache coherency features for optimal performance.

Part Context

This component belongs to the 66AK2Hxx family within the Texas Instruments Keystone II product line. It shares the same 1517-pin AAW package and core architecture variants as the 66AK2H14 and 66AK2H06, differing primarily in the number of active DSP cores and the presence of 10-GbE interfaces.

Replacement Considerations

Direct functional replacements within the same package include the 66AK2H14 (adds 10GbE) and 66AK2H06 (reduces DSP count to four). Cross-family migration requires significant architectural redesign.
