66AK2H12BAAW24

Overview

The Texas Instruments 66AK2H12BAAW24 is a multicore System-on-Chip (SoC) 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 Gigabit Ethernet switch. Peripheral connectivity includes USB 3.0, PCIe Gen2, Serial RapidIO, HyperLink, and multiple serial interfaces.

Feature Summary

• Eight C66x DSP cores providing up to 9.6 GHz total processing power
• Four ARM Cortex-A15 MPCore processors for system control
• Integrated Network Coprocessor with Packet and Security Accelerators
• Dual 72-bit DDR3/DDR3L EMIFs with speeds up to 1600 MHz

Applications

• Mission critical embedded infrastructure
• Cloud computing and high-performance computing
• Media processing and transcoding
• Network security and virtual desktop infrastructure

Procurement Notes

Verify the specific suffix 'B' in the part number against official documentation to confirm manufacturing grade or revision details. Confirm package dimensions and pinout compatibility during integration planning. Ensure supply chain sources provide valid production data sheets.

Selection Notes

Select this model when eight DSP cores are required alongside a quad-core ARM processor. Compare against the 66AK2H14 if ten-gigabit Ethernet support is needed, as the 66AK2H12 lacks XFI ports. Evaluate thermal requirements for the 1517-pin FCBGA package under maximum load conditions.

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 higher-end 66AK2H14 and the lower-core-count 66AK2H06, maintaining full peripheral sets except for the 10-GbE interface found only in the 66AK2H14.
