66AK2E05XABDA4

Overview

The Texas Instruments 66AK2E05XABDA4 is a high-performance multicore 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 a 4MB shared L2 cache for ARM cores and 512KB of local L2 memory per DSP core. Connectivity includes an eight-port Gigabit Ethernet switch, a two-port 10-Gigabit Ethernet switch, two PCIe Gen2 controllers, and USB 3.0 support. It utilizes a 72-bit DDR3/DDR3L interface running up to 1600 MTPS and is housed in a 1089-pin FCBGA package.

Feature Summary

• Quad-core ARM Cortex-A15 MPCore cluster with 4MB shared L2 cache
• Single TMS320C66x DSP CorePac delivering 38.4 GMacs/core fixed-point performance
• Integrated network subsystem with 8 SGMII ports and 2 XFI/SGMII ports supporting IEEE 1588 v2
• Multicore Shared Memory Controller (MSMC) with 2MB SRAM and hardware security accelerators

Applications

• Enterprise networking infrastructure equipment
• Cloud computing and data center networking
• Avionics and defense systems
• Industrial automation and process control

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product status documentation. Confirm that the component meets RoHS compliance requirements for the intended deployment region. Ensure that static discharge precautions are observed during handling due to the sensitivity of the semiconductor die.

Selection Notes

Select this model when a balance of general-purpose processing and high-throughput signal manipulation is required within a single chip. The integrated 10-Gigabit Ethernet switch reduces external component count for high-bandwidth applications. Evaluate the power consumption profile against thermal constraints, as the device supports SmartReflex automatic voltage scaling.

Part Context

This component belongs to the 66AK2E0x family of KeyStone II SoCs. It shares the same physical package and pinout as the 66AK2E02 but differs in core configuration. While the 66AK2E02 contains one ARM core and one DSP core, the 66AK2E05 scales this to four ARM cores and one DSP core, offering higher aggregate processing throughput for complex workloads.

Replacement Considerations

The 66AK2E02 serves as a lower-core-count alternative within the same package footprint. Cross-referencing with the 66AK2Hxx series requires careful evaluation of the HyperLink interconnect capabilities and the number of available DSP cores, as these architectures differ significantly from the K2E platform.
