DS28E18 1-Wire® to I2C/SPI Bridge

Analog Devices DS28E18 1-Wire^® to I²C/SPI Bridge enables the sensor to be controlled by two wires from the host system. The DS28E18 simple communications bridge reduces the wire count from six (for SPI) or four (for I²C). The two wires use Maxim’s 1-Wire protocol that combines power and signal on a single wire and is driven by the programmable I/O pins on the host’s microcontroller. Analog Devices’s 1-Wire protocol combines power and signal on a single wire driven by the programmable I/O pins on the host’s microcontroller. The 1-Wire network supports connection lengths up to 100m and ten sensor nodes or more. The two wires from the host system implement this protocol.
