66AK2H06DAAW2

Overview

The 66AK2H06DAAW2 is a Texas Instruments multicore system-on-chip based on the KeyStone II architecture. It integrates four ARM Cortex-A15 MPCore processors running at up to 1.4 GHz and four TMS320C66x DSP cores operating at up to 1.2 GHz. The device provides 6 MB of shared MSMC SRAM, two 72-bit DDR3/DDR3L memory interfaces supporting speeds up to 1600 MHz, and a five-port Gigabit Ethernet switch. Peripheral connectivity includes USB 3.0, PCIe Gen2, Serial RapidIO, HyperLink, and multiple serial interfaces.

Feature Summary

• Integrated processing cluster with four ARM Cortex-A15 cores (up to 1.4 GHz) and four C66x DSP cores (up to 1.2 GHz).
• On-chip memory includes 6 MB MSMC SRAM, 4 MB shared ARM L2 cache, and 1024 KB local L2 cache per DSP core.
• Network coprocessor featuring a packet accelerator for IPsec/GTP-U support and a security accelerator engine.
• Five-port Gigabit Ethernet switch with four SGMII ports and integrated IEEE 1588 time synchronization support.

Applications

• Cloud computing infrastructure
• Media processing and transcoding
• High-performance computing applications
• Security gateways and virtual desktops
• Video and imaging analytics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product folder to confirm package type, temperature range, and silicon revision. Confirm that the required hardware features, such as the number of active DSP cores or specific peripheral configurations, align with the 66AK2H06 variant specifications before procurement.

Selection Notes

Select this model when four DSP cores are sufficient for the computational load, distinguishing it from the 66AK2H12 and 66AK2H14 variants which offer eight cores. Ensure the design accommodates the 1517-pin FCBGA package dimensions and supports the necessary voltage rails for the SmartReflex variable supply and peripheral I/O levels.

Part Context

This component belongs to the 66AK2Hxx family of multicore DSP+ARM KeyStone II System-on-Chips. It shares the same physical package and base architecture as the 66AK2H12 and 66AK2H14 models, differing primarily in the number of active C66x DSP cores and associated timer counts.

Replacement Considerations

Direct functional replacements within the same package include the 66AK2H12DAAW2 and 66AK2H14DAAW2, which provide higher core counts but maintain pin compatibility. Verify software licensing and feature enablement requirements if migrating between these variants.
