66AK2H12DAAW24

Overview

The Texas Instruments 66AK2H12DAAW24 is a multicore System-on-Chip (SoC) based on the KeyStone II architecture. It integrates four ARM Cortex-A15 MPCore processors operating at up to 1.4 GHz and eight TMS320C66x DSP cores running at up to 1.2 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 a five-port Ethernet switch. It operates within an extended temperature range of -40°C to +100°C and utilizes a 1517-pin FCBGA package.

Feature Summary

• Integrated processing: Four ARM Cortex-A15 cores (up to 1.4 GHz) and eight C66x DSP cores (up to 1.2 GHz).
• Memory subsystem: 6 MB MSMC SRAM and two 72-bit DDR3/DDR3L interfaces supporting up to 1600 MHz.
• Network acceleration: Network coprocessor with packet accelerator, security engine, and five-port Gigabit Ethernet switch.
• High-speed peripherals: Includes USB 3.0, PCIe Gen2, Serial RapidIO, HyperLink, and EDMA3.

Applications

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

Procurement Notes

Verify the specific suffix 'W24' against official documentation to confirm the exact frequency bin and temperature grade. Ensure compatibility with the EVMK2H development ecosystem for software validation. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly.

Selection Notes

Select this model when eight DSP cores are required alongside four ARM application processors. Compare against the 66AK2H06 variant if fewer DSP or ARM cores suffice for the workload. Verify that the 1517-pin BGA footprint fits the target PCB design constraints.

Part Context

This component belongs to the 66AK2Hxx family, which also includes the 66AK2H14 and 66AK2H06. The 66AK2H12 serves as the mid-range option in this series, offering a balance between the higher core count of the 66AK2H14 and the lower cost of the 66AK2H06.

Replacement Considerations

The 66AK2H14AXAAW24 is a related part number within the same family but contains eight ARM cores instead of four. Cross-referencing pinouts and software configurations is necessary when substituting between these variants.
