Designers expanding connections to remote sensor networks can now reduce complexity and cost to the industry’s lowest levels with the DS28E18 1-Wire®-to-I2C/SPI Bridge from Maxim Integrated Products. By leveraging Maxim Integrated’s 1-Wire protocol to interface with I2C and SPI-compatible sensors, the DS28E18 reduces complexity by connecting devices using only two wires compared to competitive solutions that require four wires for I2C or six for SPI.

Nowadays, most designers use serial interfaces to connect remote sensors in industrial and remote monitoring applications. However, the most popular protocols are costly and complex because they require up to five external switch extenders to reach devices at distances as long as 100 meters. In addition, some of the interfaces widely deployed today require six cables for connecting multiple extended sensors to a host microcontroller (more info).
