ICM-42688-P

Input Voltage Range: 1.71V to 3.6V
Digital-output X-, Y-, and Z-axis angular rate sensors (gyroscopes) with programmable full-scale range of ±15.625, ±31.25,±62.5, ±125, ±250, ±500, ±1000, and ±2000 degrees/sec
Digital-output X-, Y-, and Z-axis accelerometer with programmable full-scale range of ±2g, ±4g ±8g and ±16g
The host interface can be configured to support I3CSM slave, I2C slave, or SPI slave modes. The I3CSM interface supports speeds up to 12.5MHz (data rates up to 12.5Mbps in SDR mode, 25Mbps in DDR mode), the I2C interface supports speeds up to 1 MHz, and the SPI interface supports speeds up to 24 MHz.
Digital-output temperature sensor
I2C Address: 0x68 (AD0=0), 0x69 (AD0=1)
