66AK2E02ABDA4

Overview

The Texas Instruments 66AK2E02ABDA4 is a KeyStone II System-on-Chip (SoC) featuring one ARM Cortex-A15 processor core and one TMS320C66x DSP core, both operating at up to 1.4 GHz. It integrates 4 MB of shared L2 cache for the ARM cores and 512 KB of local L2 memory per DSP core. The device includes a 2 MB Multicore Shared Memory Controller (MSMC), a 72-bit DDR3/DDR3L interface supporting speeds up to 1600 MTPS, and an EMIF16 interface. Connectivity comprises two PCIe Gen2 controllers, two USB 2.0/3.0 controllers, eight SGMII ports, and a 10-Gigabit Ethernet switch subsystem with MACSEC support.

Feature Summary

• Dual-core architecture combining one ARM Cortex-A15 MPCore and one C66x DSP CorePac running at frequencies up to 1.4 GHz.
• Integrated network coprocessor providing packet acceleration for IPsec, GTP-U, SCTP, PDCP, and security acceleration for IPSec and SRTP.
• High-performance I/O including an 8-port Gigabit Ethernet switch, a 10-GbE switch subsystem, and HyperLink for chip-to-chip interconnects.
• KeyStone II architecture utilizing TeraNet switch fabric and Multicore Navigator for efficient zero-overhead packet-based communication.

Applications

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

Procurement Notes

Verify the specific suffix 'ABDA4' against the official datasheet nomenclature table to confirm package type, temperature range, and production status. Confirm that the Security Accelerator functions are enabled for the intended shipment, as these features are subject to export control regulations.

Selection Notes

Select this model when a single DSP core paired with a single ARM core is sufficient for Layer 1 and Layer 2 processing tasks. Compare against the 66AK2E05 if four ARM cores or dual 10-GbE ports are required. Ensure the design supports the 28 nm process requirements and utilizes SmartReflex voltage scaling for power optimization.

Part Context

This component belongs to the 66AK2E0x family within the KeyStone II product line. It serves as a lower-core-count alternative to the 66AK2E05, which features four ARM cores and additional 10-GbE ports. Both devices share the same underlying architecture and peripheral sets, differing primarily in core count and specific port configurations.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate the 66AK2E05 for increased ARM core capacity or other KeyStone II variants based on specific performance and connectivity requirements.
