DS2488X+T

Controllers Overview

The DS2488X+T is a dual-port 1-Wire bridge device manufactured by Analog Devices Inc./Maxim Integrated. It facilitates communication between two microcontroller subsystems via independent IOA and IOB interfaces, supporting up to 512kbps pass-through mode for large data transfers. The device operates within a voltage range of 1.71V to 3.63V and features three open-drain GPIO pins. It includes a unique 64-bit factory-programmed ROM ID and an 8-byte message buffer. The component is housed in an 8-ball WLP package (1.6mm x 0.9mm x 0.33mm) and supports an operating temperature range from -40°C to +85°C.

Controllers Feature Summary

• Enables bidirectional high-speed pass-through communication between two host controllers using the 1-Wire interface.
• Supports power delivery modes where the device detects high voltage on the IOA pin to control external charging circuits.
• Provides parasitic power operation capability derived directly from the 1-Wire IOA line for simplified system design.

Controllers Applications

• True Wireless Stereo (TWS) earbuds and charging cases
• Communication and control bridging between subsystems
• Wearable devices requiring low-power interconnects

Controllers Procurement Notes

Verify the specific suffix designation (+T) against the manufacturer's current datasheet to confirm packaging type and RoHS compliance status. Ensure that the ordering information matches the exact revision required for your hardware design, as manufacturing updates may alter physical dimensions or electrical characteristics over time.

Controllers Selection Notes

Select this component when a minimalist dual-interface solution is required to link separate microcontroller domains without complex protocol translation. Consider the 8-ball WLP package constraints for PCB layout and verify that the 1.71V to 3.63V operating voltage aligns with the target subsystem power rails.

Controllers Part Context

This part belongs to the DS2488 family of 1-Wire Dual-Port Links designed for connecting independent controller systems. It serves as a specialized bridge allowing distinct subsystems to exchange data and state information through a single dedicated contact per side, reducing pin count and board complexity compared to traditional multi-wire interfaces.

Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing firmware drivers if considering alternative bridge ICs, as the DS2488 utilizes proprietary 1-Wire command sets and arbitration logic.
