66AK2H12DAAWA24

Overview

The 66AK2H12DAAWA24 is a KeyStone II System-on-Chip integrating eight TMS320C66x DSP cores and four 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. Each core includes 32 KB L1P, 32 KB L1D, and 1 MB L2 cache. The ARM cluster runs at up to 1.4 GHz with 4 MB shared L2 cache. It features a 6 MB MSM SRAM, dual 72-bit DDR3/DDR3L interfaces supporting speeds up to 1600 MHz, and peripherals including USB 3.0, PCIe Gen2, SRIO, and a five-port Gigabit Ethernet switch.

Feature Summary

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

Applications

• Cloud computing infrastructure
• High-performance computing and transcoding
• Media processing and video analytics
• Virtual desktop infrastructure
• Mission-critical networking equipment

Procurement Notes

Verify the device revision ID via the JTAGID register or CorePac Revision ID Register to confirm silicon stepping. Confirm that the specific ordering suffix corresponds to the required commercial temperature range (0°C to 85°C) and package variant. Ensure compatibility with the EVMK2H development environment for initial validation.

Selection Notes

Select this model when eight DSP cores are required alongside an ARM application processor. Compare against the 66AK2H14 if ten-gigabit Ethernet ports are necessary, as they are absent in the 66AK2H12. Verify that the 1517-pin FCBGA footprint fits the target PCB design constraints.

Part Context

This component belongs to the 66AK2Hxx family within the Texas Instruments KeyStone II architecture portfolio. It shares the same physical package and peripheral set as the 66AK2H14 and 66AK2H06, differing primarily in the number of active DSP and ARM cores and the presence of 10-GbE ports.

Replacement Considerations

Public confirmed substitute part numbers: 66AK2H14AXAAW24, 66AK2H06AAWA2.
