66AK2H14BXAAW24

Overview

The Texas Instruments 66AK2H14BXAAW24 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, while the ARM cores reach 1.4 GHz. It includes 6 MB of shared MSMC SRAM, dual 72-bit DDR3/DDR3L interfaces supporting speeds up to 1600 MHz, and a 10-Gigabit Ethernet switch subsystem with two XFI ports. The device integrates a Network Coprocessor for packet acceleration and security, 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)
• Integrated 10-GbE switch subsystem with IEEE 1588 support
• Network Coprocessor providing hardware acceleration for IPsec, SSL/TLS, and packet processing
• Dual 72-bit DDR3/DDR3L memory controllers with speeds up to 1600 MHz

Applications

• Mission critical infrastructure systems
• High-performance computing and cloud computing nodes
• Media processing and transcoding equipment
• Networking and security appliances

Procurement Notes

Verify the specific suffix 'X' against official documentation to confirm any deviations from standard commercial or extended temperature ranges. Ensure compatibility with the EVMK2H development platform if prototyping. Confirm that the required security accelerator functions are enabled for the specific shipment batch as per export control regulations.

Selection Notes

Select this model when high-throughput packet processing and cryptographic acceleration are required alongside general-purpose ARM control. The 66AK2H14 variant is distinct due to its dedicated 10-Gigabit Ethernet switch, which is absent in the 66AK2H12 and 66AK2H06 models. Evaluate power consumption requirements given the SmartReflex variable supply capabilities.

Part Context

This component belongs to the 66AK2Hxx family, which also includes the 66AK2H12 and 66AK2H06. These devices share the same KeyStone II architecture and package footprint but differ in core counts and peripheral availability. The 66AK2H14 provides the highest performance tier within this series, specifically adding the 10-GbE switch functionality found only in this part number.

Replacement Considerations

Public confirmed substitute part numbers: 66AK2H12DAAW24, 66AK2H06AAWA2.
