... CMOS sensor conditioning circuitry to create a low cost, high performance Digital Output Pressure (14bit) and Temperature (11bit) transducer designed to meet the strictest requirements from OEM customers. The MS4525DO is fully calibrated and temperature compensated with a total error band (TEB) of less than 1.0% over the compensated pressure range. The sensor operates from single supply of either 3 ...

... I2C communication occurs. 1.4 Transfer sequences Transmission START Condition (S): The START condition is a unique situation on the bus created by the master, indicating to the slaves the beginning of a transmission sequence (the bus is considered busy after a START).

... Handshake procedure (Hold Master master-slave system, the master dictates when the slaves will receive or transmit data. However, in some situations a slave device may need time to store received data or prepare data to be transmitted. Therefore, a handshake procedure is required to allow the slave to indicate termination of internal processing MS4525DO www.meas-spec.com 12/17 January 2011 ...

... The I2C master command starts with the 7bit slave address with the 8th bit =1 (READ).The sensor as the slave sends an acknowledge (ACK) indicating success. The sensor has four I2C read commands: Read_MR, Read_DF2, Read_DF3, and Read_DF4.Figure 1.6 shows the structure of the measurement packet for three of the four I2C read commands, which are explained in sections 1.6.1 and 1.6.2 MS4525DO www.meas-spec.com 13/17 January 2011 ...

... If the user only requires the corrected bridge value, the read can be terminated after the 2nd byte. If the corrected temperature is also required but only at an 8-bit resolution, the read can be terminated after the 3rd byte is read.
