OVERVIEW HSPPAD042A is the 2.0x2.5mm footprint and 0.9mm height digital interface barometric pressure sensor. Barometric pressure is detected by MEMS sensor element using piezo resistive bridge circuit formed on the silicon diaphragm. The sensor element is connected to ASIC for signal conditioning. ASIC has 17-bit ADC and temperature compensation capability. The ASIC output compensated pressure values. In addition to the compensation, this product supports averaging and filtering for lower noise, and FIFO function. I2C and SPI interface are prepared for communication. 2.

Temperature measurement and Pressure measurement is performed by setting TDET and PDET to 1, respectively. When TDET and PDET are set to "1" at the same time, Temperature measurement is done, followed by Pressure measurement. If the PDET is performed independently, the latest temperature data is used for pressure data compensation. Temperature data is stored into register address 0x09 and 0x0A, and compensated pressure data is in 0x04 to 0x06. After data store, TRDY and PDRY in STAT register is changed to "1", and TDET and PDET back to "0". TDET and PDET are accessible during measurement, but they will be effective after the measurement. Only PDRP is effective right away. After measurement, device goes to stand-by state and minimizes current consumption, then waiting for next command.

In order to move into this mode, CTL2.PMES must be set "1". Measurement is started immediately after mode transition and following measurement is repeated. In this mode, regulator will not be inactive in standby period and keeps consuming current. If ODR is changed in this mode, new measurement will be performed immediately and repeat following measurement. However, ODR change is done in measurement period, new measurement will start right after the measurement finished. ALPS ELECTRIC CO.,LTD.

Read Pointer is incremented when the sensor data is read. Number of stored data is indicated by FFST.FP, if the FP (FIFO Pointer) is greater or equal to WMT (Water Mark Pointer) then FFST.FFEV becomes "1". All 16 steps FIFO memory are filled by the sensor data, the most oldest data is discarded and Read Pointer is incremented. All data in FIFO memory is discarded when FFEN is set to "0".

In Register Action Mode and Command Action mode, simple average is calculated. Measurement is performed after the command PDET is issued . Temperature is measured by specified frequency by AVCL.TFRQ. The measurement repeats until specified number of data is collected. Each data are temperature compensated with the latest temperature data.

Number of TAP can be specified at CTL1.PTAP. Output data accuracy is increased by larger number of TAP, however, current consumption is increased too. This TAP setting is effective to pressure reading only and fixed for temperature.

Once software reset command is detected, digital regulator is disabled and all register values are reset. Then transfer to Register Action Mode and Standby state. After Software reset command, command can not be received for 2.2msec to complete POR. ALPS ELECTRIC CO.,LTD.
