The S-5851A Series is a digital temperature sensor with 2-wire serial interface. By transmission using the SCL and SDA
pins, users are able to Read temperature data and set the various modes for the S-5851A Series. Connect a bypass
capacitor of 0.1 μF between the VDD and VSS pins for proper temperature data.
1. Start condition
A start condition starts by changing the SDA line from “H” to “L” while the SCL line is “H”.
All operations start with a start condition.
2. Stop condition
A stop condition starts by changing the SDA line from “L” to “H” while the SCL line is “H”.
During Read sequence if the S-5851A Series receives a stop condition, its Read operation is interrupted.
During Write sequence if the S-5851A Series receives a stop condition, the S-5851A Series finishes installing Write
data.
