DS28E18 1-Wire® to I2C/SPI Bridge with Command Sequencer General Description The DS28E18 is a simple communications bridge that resides at a remote SPI or I2C sensor and allows the sensor to be controlled by just two wires coming from the host system.
It reduces the wire count from six (for SPI) or four (for I2C).
These two wires use Maxim’s 1-Wire protocol that combines power and signal on a single wire, and which is driven by the programmable I/O pins on the host’s microcontroller.
The 1-Wire network supports connection lengths up to 100m and 10 sensor nodes or more.
The IC provides a 512-byte command sequencer in ...
