Seamless I2C to 1-Wire Conversion for Embedded Systems: Maximise Protocol Compatibility with High-Performance Communication
The 7Semi DS2482-100 I2C to 1-Wire Master Breakout is a versatile and efficient solution for integrating 1-Wire devices into I2C-based systems. Built around the DS2482-100 IC, this breakout module simplifies bidirectional protocol conversion, enabling reliable communication between a standard or fast I2C master (100kHz to 400kHz) and downstream 1-Wire slave devices, including sensors, EEPROMs, and other peripherals. With built-in timing control and intelligent signal conditioning, it removes the need for software-driven waveform generation on the host side.
Ideal for embedded developers and engineers working with sensor networks or data acquisition systems, this breakout supports both standard and Overdrive 1-Wire communication speeds. The DS2482-100 manages rising and falling signal edges with programmable slew rate control, while strong pullup functionality—available internally and externally via MOSFET control—ensures compatibility with energy-demanding 1-Wire devices. The module also includes configurable I2C slave addressing via binary input pins, simplifying integration in systems with multiple I2C peripherals.
