66AK2E05XABD4

Overview

The Texas Instruments 66AK2E05XABD4 is a high-performance System-on-Chip (SoC) based on the KeyStone II architecture. It integrates four ARM Cortex-A15 processor cores and one TMS320C66x DSP core, both operating at frequencies up to 1.4 GHz. The device features 4 MB of shared L2 cache for the ARM cores and 512 KB of local L2 memory per DSP core. It includes an 8-port Gigabit Ethernet switch, a 10-Gigabit Ethernet subsystem, and a network coprocessor with security acceleration. The component is housed in a 1089-pin FCBGA package.

Feature Summary

• Quad-core ARM Cortex-A15 MPCore cluster with 4 MB shared L2 cache
• Single C66x DSP CorePac delivering 38.4 GMacs/core at 1.2 GHz
• Integrated 8-port GbE switch and 10-GbE switch subsystem
• Network Coprocessor with Packet Accelerator and Security Accelerator

Applications

• Servers
• Cloud Infrastructure
• Enterprise Networking
• Avionics and Defense
• Industrial Automation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product status documentation. Confirm that the required hardware features, such as the Security Accelerator, are enabled for the specific shipment batch as these functions may be subject to export control regulations.

Selection Notes

Select this model when a balance of general-purpose processing and high-throughput signal processing is required. The 66AK2E05 provides four ARM cores and one DSP core, distinguishing it from the single-core ARM variant. Ensure the design supports the 28 nm process technology and the specific voltage requirements for the core and I/O domains.

Part Context

This component belongs to the 66AK2E0x family within the KeyStone II series. It shares the same architectural foundation as the 66AK2Hxx series but offers a different core configuration optimized for enterprise networking and cloud infrastructure applications rather than high-end data center scaling.

Replacement Considerations

Public confirmed substitute part numbers only; omit otherwise.
