The recommended power-on sequence is to first apply VDD (1.71V to 3.6V) and then apply VDDIO (1.71V to 3.6V). The power-on sequence is not critical, but it is recommended to power on VDD before VDDIO to ensure proper operation.
To configure the LIS2L02AQ3TR for high-precision mode, set the ODR (Output Data Rate) to 10 Hz or lower, and set the FS (Full Scale) to ±2g or ±4g. Additionally, enable the low-pass filter (LPF) and set the cutoff frequency to 10 Hz or lower.
The maximum sampling rate of the LIS2L02AQ3TR is 1.67 kHz (ODR = 1600 Hz). However, the maximum sampling rate may be limited by the bandwidth of the host interface (e.g., I2C or SPI).
The LIS2L02AQ3TR generates interrupts on events such as data ready, FIFO threshold reached, and error detection. To handle interrupts, configure the interrupt pins (INT1 and INT2) and enable the corresponding interrupt sources in the device. Then, in the host microcontroller, configure the interrupt service routine to read the interrupt status register and clear the interrupt flags.
The typical current consumption of the LIS2L02AQ3TR is 2.5 mA (VDD = 1.8V, ODR = 100 Hz, FS = ±2g). However, the current consumption may increase depending on the operating conditions, such as the output data rate and the full-scale range.
