1. Introduction The SPL06-001 is a miniaturized Digital Barometric Air Pressure Sensor with a high accuracy and a low current consumption. The SPL06-001 is both a pressure and a temperature sensor. The pressure sensor element is based on a capacitive sensing principle which guarantees a high precision during temperature changes. The small package makes the SPL06-001 ideal for mobile applications and wearable devices. The SPL06-001‘s internal signal processor converts the output from the pressure and temperature sensor elements to 24-bit results. Each pressure sensor has been calibrated individually and contains calibration coefficients. The coefficients are used in the application to convert the measurement results to true pressure and temperature values. The SPL06-001 has a FIFO that can store the latest 32 measurements. By using the FIFO, the host processor can remain in a sleep mode for a longer period of time between readouts. This can reduce the overall system power consumption. Sensor measurements and calibration coefficients are available through the serial I2C interface.

5. Operation 5.1 Operating Modes The SPL06-001 supports 3 different modes of operation: Standby, Command, and Background mode. • Standby Mode - Default mode after power on or reset. No measurements are performed. - All registers and compensation coefficients are accessible. • Command Mode - One temperature or pressure measurement is performed according to the selected precision. - The sensor will return to Standby Mode when the measurement is finished, and the measurement result will be available in the data registers. • Background Mode - Pressure and/or temperature measurements are performed continuously according to the selected measurement precision and rate. The temperature measurement is performed immediately after the pressure measurement. - The FIFO can be used to store 32 measurement results and minimize the number of times the sensor must be accessed to read out the results. Note: Operation mode and measurement type are set in the Sensor Operating Mode and Status (MEAS_CFG) register. 5.2 Measurement Precision and Rate Different applications require different measurement precision and measurement rates. Some applications, like weather stations, require lower precision and measurement rates than for instance indoor navigation and sports applications. The SPL06-001's measurement precision and rate (in background mode) can be configured to match the requirements of the application in which it is being used. This reduces current consumption of the sensor and the system. In order to achieve a higher precision, the SPL06-001 will read the sensor multiple times (oversampling), and combine the readings into one result. This increases the current consumption and the measurement time, which again reduces the maximum measurement rate. The measurement precision, rate and time is set in the Pressure Configuration (PRS_CFG) and Temperature Configuration (TMP_CFG) registers. The register descriptions contain information about the current consumption and the possible combinations of measurement precision, time, and rate. Please note that the pressure sensor is temperature dependent. Temperature measurements must be made together with the pressure measurements in order to compensate for the temperature dependency. This reduces the maximum pressure measurement rate, since: Ratetemperature*Timetemperature + Ratepressure*Timepressure< 1 second. Measurement Settings and Use Case Examples contains a table with examples of combinations of pressure and temperature precision and rates for different use cases. _________________________ ____________________________________________ __ Version 2.0 8 / 31 CONFIDENTIAL
