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.

Continuous Measurement Mode executes measurement with specified frequency by
CTL2.ODR. 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.

Register Action Mode allows access to ACTL1 and execute each functions by setting
"1" for each bit. 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.

Write pointer is incremented when the sensor data is stored into FIFO memory, and
next data is stored to next register. 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".

There are 16 steps FIFO for Pressure read data. FIFO function can be enabled by
setting FCTL.FFEN=1.

The measurement repeats until specified number of data is collected. Each data are
temperature compensated with the latest temperature data. Then, average is calculated and
the result is stored into POUT.

In Continuous Mode, moving average is calculated. Set CTL2.MODE=01 with
AVCL.AVG>0, periodical measurement is started. Average is calculated when every
measurement is done and the result is stored into POUT. Moving average can update
averaged data at every measurement, so sampling rate won't be compromised. When
first few measurement, number of data is not sufficient to specified average number, in
this case necessary data is supplemented by initial data.

Digital output data from DSADC is processed at CIC filter in the digital block. 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.

I2C interface specification conforms Philips I2C-BUS Specification version 2.1 and NXP
UM10204 I2C-BUS Specification and user manual Rev.03-19 June 2007. The slave address is
1001000x (x= Write:0, Read:1). Standard mode (100kHz), Fast mode (400kHz), Fast mode
plus (1MHz) and High-speed mode (3.4MHz) are supported. Multiple read and write is
supported and register address is automatically incremented every read or write.
High-speed mode is selected when master code (00001xxx) is received instead of slave
address. Once master code is received, the product return NAK.
The device works in Fast mode plus and High-speed mode with power supply less than 2.5V.
Please contact us, if the device needs to be operated in those mode with or higher power
supply. Different factory calibration will be done before shipment.

4-wire SPI Bus Read Protocol
- The SPI communication is start form CSB changed to LOW and end by CSB changed to HIGH.
And in this case, SCK should be HIGH. Reading or Writing can be started with the control bit RW
(RW=0: Writing, RW=1:Reading). 7bit following RW bit are register address (AD6 to AD0) and
then data is coming as DO7～DO0、DO15～DO8・・・.SDI is latched at raise time of clock and
SDO is changed at fall time of clock.
- Read command for SPI need 16 clock at least , and when reading, it is necessary
to add every 8 clocks
Reading at SPI 4-wire

bit 8-15 : Data DO[7:0]、MSB first
