COMMUNICATION INTERFACE
I2C SLAVE INTERFACE & MEASUREMENT METHOD OF PRESSURE AND TEMPERATURE
- Slave device
- 7-bit addressing, Combined format
- Support Fast-mode, Hs-mode
- It does not support 10-bit addressing
- The device address can be changed and the standard setup is "1001000"
- Data transfers follow the combined format with 7-bit addressing of I2C interface.
- Data is transferred with the most significant bit (MSB) first and big endian.

Write Format
- For starting full measurement, Set command "0xAC" .
Read Format
- After active measurement time (MAX.10ms), the Acquired data stored to output register
- These data are compensated, but unit conversion is not carried out
- To convert it into the unit converted value, it calculates as follows.
Unit conversion
Pressure [hPa] = PRESS. DATA × 860 / 65535 + 250
Temperature [°C] = TEMP. DATA × 125 / 65535 - 40
- Temperature accuracy is not guaranteed.
