66AK2H06AAAWA2

Overview

The 66AK2H06AAAWA2 is a multicore system-on-chip from Texas Instruments based on the KeyStone II architecture. It integrates four TMS320C66x DSP cores operating at up to 1.2 GHz and two ARM Cortex-A15 processors running at up to 1.4 GHz. The device features 6 MB of shared MSMC SRAM, packet acceleration, and security acceleration engines. Connectivity includes dual 72-bit DDR3 interfaces, USB 3.0, PCIe Gen2, Serial RapidIO, and a five-port Gigabit Ethernet switch. It is housed in a 1517-pin FCBGA package with an extended temperature range of -40°C to 100°C.

Feature Summary

• Four C66x DSP cores (up to 1.2 GHz) and two ARM Cortex-A15 cores (up to 1.4 GHz)
• 6 MB Multicore Shared Memory Controller (MSMC) SRAM
• Network Coprocessor with Packet Accelerator and Security Accelerator
• Dual 72-bit DDR3/DDR3L memory controllers supporting speeds up to 1600 MHz
• Five-port Gigabit Ethernet switch subsystem with IEEE 1588 support

Applications

• Cloud computing infrastructure
• High-performance media processing and transcoding
• Virtual desktop infrastructure
• Security appliances and analytics
• Embedded networking equipment

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product folder to confirm availability and exact specifications. Confirm that the required silicon revision matches the design requirements, as JTAG IDs and CorePac revisions vary by production lot. Ensure compliance with export control regulations regarding the enabled Security Accelerator functions for the intended destination.

Selection Notes

Select this model when four DSP cores and two ARM cores are sufficient for the application workload. Compare against the 66AK2H12 and 66AK2H14 variants if additional DSP cores or ten-gigabit Ethernet ports are required. Verify that the 1517-pin AAW package footprint aligns with the PCB layout constraints and thermal management capabilities of the target system.

Part Context

This component belongs to the 66AK2Hxx family of KeyStone II System-on-Chips. It shares the same physical package and core architecture as the 66AK2H14 and 66AK2H12 models. The primary distinctions lie in the number of active DSP and ARM cores, as well as the presence or absence of the 10-GbE switch subsystem found in higher-end variants.

Replacement Considerations

Direct pin-compatible replacements within the same package include the 66AK2H12 and 66AK2H14 models, provided the reduced core count does not impact performance requirements.
