how to improve the actual ODR of LIS2DH12 ?

[JohnGe]

In my design, when setting the ODR = 100Hz or below ,  I can get 100hz INT signals , and received 100 sets vibration data every Second.  （Using XYZ data-ready as int1）and modify the ODR setting to 200Hz , just get 200 hz INT signals ，and received 145 sets data。

How to improve the actual ODR ?  We want  realize 1.376KHz @hr_it mode

 or 5.376kHz @LP mode,  Which mcu is suitable ?  STM32F103  70MHz ?  or  higher End ?   
And I2C interface is suitable for 5.376kHz ? or must be SPI ？

Hi @JohnGe ,

You need to use SPI @ 10MHz and an powerful mcu to manage that interrupt velocity such as a STM32U5.

For further questions I suggest you to open a topic on the MCU forum.
