66AK2H06DAAWA2

Overview

The Texas Instruments 66AK2H06DAAWA2 is a KeyStone II System-on-Chip integrating four TMS320C66x DSP cores and two ARM Cortex-A15 processors. The C66x cores operate at up to 1.2 GHz, delivering 38.4 GMACs/core for fixed-point and 19.2 GFlops/core for floating-point processing. The ARM cores run at up to 1.4 GHz with 4 MB of shared L2 cache. The device includes 6 MB of MSMC SRAM, a Network Coprocessor with security acceleration, and peripherals such as USB 3.0, PCIe Gen2, and a five-port Gigabit Ethernet switch. It is housed in a 1517-pin FCBGA package.

Feature Summary

• Four TMS320C66x DSP cores (up to 1.2 GHz) and two ARM Cortex-A15 MPCore processors (up to 1.4 GHz)
• 6 MB Multicore Shared Memory Controller (MSMC) SRAM shared across all cores
• Network Coprocessor featuring Packet Accelerator and Security Accelerator for IPsec and SSL/TLS
• Integrated peripherals including USB 3.0, PCIe Gen2, Serial RapidIO, and five-port Gigabit Ethernet switch

Applications

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

Procurement Notes

Verify the specific suffix 'DAAWA2' against the manufacturer's current datasheet revision G (SPRS866G). Confirm that the operating temperature range matches the extended case specification (-40°C to 100°C) required for the application environment. Ensure compatibility with the 1517-pin FCBGA footprint during PCB layout.

Selection Notes

Select this model over the 66AK2H12 or 66AK2H14 if the application requires only four DSP cores and two ARM cores. Note that the 66AK2H06 lacks the 10-Gigabit Ethernet subsystem found in the 66AK2H14. Verify that the 4096 KB shared L2 cache for DSP cores meets the memory bandwidth requirements compared to the larger capacities in higher-tier devices.

Part Context

This component belongs to the 66AK2Hxx family of multicore DSP+ARM KeyStone II SoCs from Texas Instruments. It shares the same 0.028 µm process technology and 1517-pin AAW package as the 66AK2H12 and 66AK2H14. The primary differentiation lies in the number of active DSP and ARM cores, as well as the presence or absence of the 10-GbE interface.

Replacement Considerations

Direct pin-compatible replacements within the same package include the 66AK2H12DAAWA2 and 66AK2H14DAAWA2. These offer increased core counts but maintain software backward compatibility via the KeyStone II architecture.
