66AK2H12AAAWA2

Overview

The Texas Instruments 66AK2H12AAAWA2 is a multicore System-on-Chip (SoC) based on the KeyStone II architecture. It integrates four ARM Cortex-A15 MPCore processors running at up to 1.4 GHz and eight TMS320C66x DSP cores operating 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 Gigabit Ethernet switch. It includes hardware accelerators for packet processing and security, along with peripherals such as USB 3.0, PCIe Gen2, Serial RapidIO, and HyperLink. The component is housed in a 1517-pin flip-chip plastic BGA package.

Feature Summary

• Integrated quad ARM Cortex-A15 cores (up to 1.4 GHz) and eight C66x DSP cores (up to 1.2 GHz)
• KeyStone II architecture with Multicore Navigator and Network Coprocessor
• Dual 72-bit DDR3/DDR3L interfaces supporting up to 1600 MHz
• Five-port Gigabit Ethernet switch with Packet Accelerator and Security Accelerator

Applications

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

Procurement Notes

Verify the specific suffix 'AAW' against the manufacturer's current ordering information to confirm package type and temperature range. Confirm RoHS compliance status and any export control restrictions associated with the Security Accelerator functions before procurement.

Selection Notes

Select this model when eight DSP cores are required alongside four ARM application processors. Compare against the 66AK2H14 if ten-gigabit Ethernet ports are needed, or the 66AK2H06 if only four DSP cores are sufficient for the workload.

Part Context

This part belongs to the 66AK2Hxx family of multicore DSP+ARM SoCs. It shares the same 1517-pin AAW package and core architecture as the 66AK2H14 and 66AK2H06, differing primarily in peripheral availability and core count configurations.

Replacement Considerations

Direct functional replacements within the same package include the 66AK2H14AAAWA2 and 66AK2H06AAAWA2. Verify pin compatibility and software configuration differences regarding disabled peripherals.
