66AK2H12BAAWA24

Overview

The Texas Instruments 66AK2H12BAAWA24 is a KeyStone II System-on-Chip featuring 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. 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 Packet and Security Accelerators, 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

• Eight C66x DSP cores (up to 1.2 GHz) and four ARM Cortex-A15 cores (up to 1.4 GHz)
• Network Coprocessor supporting IPsec, GTP-U, and SSL/TLS security acceleration
• Integrated five-port Gigabit Ethernet switch with IEEE 1588 support
• Multicore Navigator with hardware queues and packet-based DMA

Applications

• Mission critical infrastructure systems
• High-performance computing and cloud computing nodes
• Media processing and transcoding applications
• Networking and analytics platforms

Procurement Notes

Verify the specific suffix 'B' against the official datasheet nomenclature table to confirm frequency bins or silicon revision. Ensure the ordering code matches the exact pinout and thermal specifications required for the target PCB design. Cross-reference the package marking with the manufacturer's orderable information sheet.

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 needed, or the 66AK2H06 if fewer cores suffice. Verify that the system power budget accommodates the SmartReflex variable core supply and peripheral I/O voltages ranging from 0.85 V to 3.3 V.

Part Context

This component belongs to the 66AK2Hxx family within the Texas Instruments KeyStone II architecture portfolio. It shares the same 1517-pin AAW package and base peripheral set as the 66AK2H14 and 66AK2H06, differentiated primarily by the number of active DSP and ARM cores and specific memory configurations.

Replacement Considerations

Direct functional replacements within the same package include the 66AK2H14AAXAW24 and 66AK2H06AAWA24. Note that the 66AK2H14 variant includes additional 10-GbE XFI ports which are reserved on the 66AK2H12.
