LAN9694TSN-V/3KW

Controllers Overview

The LAN9694TSN-V/3KW is a Time-Sensitive Networking-enabled industrial Ethernet switch from the Microchip LAN969x family. It provides a non-blocking switching bandwidth of 46 Gbps and integrates a 1 GHz single-core Arm Cortex-A53 CPU with DDR3/DDR4 SDRAM controller. The device supports flexible interface options including 1, 2.5, 5, and 10 GbE ports, along with an additional 2.5 GbE node processor interface port. Key specifications include IEEE 802.1Q VLAN support with 16K MAC addresses and 4K VLANs, Layer 3 unicast/multicast routing, and comprehensive TSN features such as 802.1Qbv, 802.1Qch, 802.1Qci, 802.1AS-2020, 802.1CB, and 802.1Qbu. It operates within an extended temperature range of -40°C to 110°C.

Controllers Feature Summary

• Supports complete TSN feature set including time-aware shaping, cyclic queuing and forwarding, stream policing, high-precision time synchronization, seamless redundancy, and low latency through preemption and cut-through switching.
• Integrates a 1 GHz single-core Arm Cortex-A53 CPU with PCIe 2.0/3.0 interface for full management of layer 2 and layer 3 industrial Ethernet switching.
• Provides fully managed L2 switching and L3 routing features with IEEE 802.1Q VLAN switch, 16K MAC address table, and 4K VLANs.
• Includes media redundancy protocols MRP, DLR, and HSR/PRP, alongside secure boot capabilities.

Controllers Applications

• Factory, building, and substation automation
• Process control systems
• Physical security infrastructure
• Intelligent transportation systems

Controllers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type, temperature grade, and lead time requirements. Ensure compatibility with existing system power supplies and clock configurations before procurement. Confirm RoHS compliance status and moisture sensitivity level handling procedures during storage and assembly.

Controllers Selection Notes

Select this model when 46 Gbps switching bandwidth meets system requirements. Consider higher bandwidth variants like LAN9696 or LAN9698 if more ports or greater throughput are needed. Verify that the integrated CPU and memory interfaces align with application software needs. Check if HSR/PRP redundancy is required; if so, choose the RED variant instead.

Controllers Part Context

The LAN9694TSN-V/3KW belongs to the LAN969x Ethernet Switch Family, which offers scalable solutions for industrial automation. This family includes LAN9694 (46 Gbps), LAN9696 (66 Gbps), and LAN9698 (102 Gbps) models. All variants share similar architectural features but differ in switching capacity and port configurations to suit various network densities.

Controllers Replacement Considerations

LAN9694RED-V/3KW provides equivalent 46 Gbps bandwidth with added HSR/PRP redundancy support. LAN9696TSN-V/3KW offers increased 66 Gbps bandwidth. LAN9698TSN-V/3KW provides 102 Gbps bandwidth. Verify pinout and software compatibility when substituting.

Controllers FAQ
