66AK2H14BAAW24

Overview

The 66AK2H14BAAW24 is a Texas Instruments multicore System-on-Chip based on the KeyStone II architecture. It integrates eight TMS320C66x DSP cores operating at up to 1.2 GHz and four ARM Cortex-A15 processors running at up to 1.4 GHz. The device features 6 MB of shared MSMC SRAM, dual 72-bit DDR3/DDR3L memory interfaces supporting speeds up to 1600 MHz, and a dedicated network coprocessor with security acceleration. Peripheral connectivity includes USB 3.0, PCIe Gen2, Serial RapidIO, and a 10-Gigabit Ethernet switch subsystem.

Feature Summary

• Eight C66x DSP cores providing up to 9.6 GHz total processing capability
• Four ARM Cortex-A15 MPCore processors with 4 MB shared L2 cache
• Dedicated Network Coprocessor with Packet Accelerator and Security Engine
• Integrated 10-Gigabit Ethernet (10GbE) Switch Subsystem with IEEE 1588 support
• Multicore Navigator with hardware queues and packet-based DMA for zero-overhead transfers

Applications

• Mission Critical Infrastructure
• Cloud Computing and High-Performance Computing
• Media Processing and Transcoding
• Security Gateways and Virtualization
• Networking and Analytics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product folder to confirm package dimensions, temperature range, and silicon revision. Confirm that the required peripherals, such as the 10GbE interface, are active for this specific variant. Ensure compliance with moisture sensitivity levels and storage requirements prior to assembly.

Selection Notes

Select this model when high-throughput packet processing and cryptographic acceleration are required alongside general-purpose computing. The 66AK2H14 variant is distinct from the 66AK2H12 and 66AK2H06 due to its inclusion of the 10-Gigabit Ethernet switch. Evaluate power consumption profiles across the SmartReflex variable supply rails during system design.

Part Context

This component belongs to the 66AK2Hxx family of Multicore DSP+ARM KeyStone II SoCs. It shares the same 1517-pin AAW flip-chip BGA package footprint as the 66AK2H12 and 66AK2H06 devices. The primary architectural differentiator is the presence of the 10GbE switch in the 66AK2H14, whereas lower-tier models omit this peripheral to reduce cost or power.

Replacement Considerations

Direct pin-compatible replacements within the same package include the 66AK2H12 and 66AK2H06; however, these lack the 10-Gigabit Ethernet switch functionality. Verify software compatibility if migrating between these variants due to peripheral register differences.
