DP83826ERHBR

Controllers Overview

The DP83826ERHBR is a low-cost, industrial-grade Ethernet Physical Layer Transceiver manufactured by Texas Instruments. It supports 10BASE-T and 100BASE-TX standards with MII and RMII digital interfaces. The device operates on dual power supplies: 1.62V to 1.98V for the core and 3V to 3.6V for I/O. It functions within an ambient temperature range of -40°C to +105°C. Key electrical specifications include a maximum data rate of 100 Mbps and a typical supply current of 55 mA. The component is housed in a 32-pin VQFN package measuring 5mm x 5mm with a height of 1.00 mm.

Controllers Feature Summary

• Supports both basic and enhanced mode configurations for industrial protocols like EtherCAT
• Integrated auto-negotiation and AutoMDIX functionality for simplified cabling
• Low-latency design optimized for real-time industrial communication applications

Controllers Applications

• EtherCAT slave station implementations
• Industrial automation control systems
• Factory networking equipment requiring robust physical layer connectivity

Controllers Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm exact operational parameters and environmental ratings. Ensure compatibility with required voltage domains and interface standards before integration into final designs.

Controllers Selection Notes

Select this component when industrial temperature ranges and low latency are critical. Confirm that the host processor supports either MII or RMII interfaces. Validate that the system power architecture can provide the necessary dual voltage rails for core and I/O sections.

Controllers Part Context

This part belongs to the DP83826 family of Ethernet PHYs from Texas Instruments. It serves as a cost-effective solution for industrial networking compared to higher-performance variants. The ERHBR designation indicates the specific temperature grade and packaging configuration within the broader product line.

Controllers Replacement Considerations

DP83826AIRHBR offers similar functionality but with a commercial temperature range instead of industrial. DP83822IRHBR provides a different feature set focused on low power consumption rather than low latency.
