MEMS Accelerometers STMicroelectronics MEMS Accelerometers include analog and digital sensors featuring up to ±400g acceleration full scale and from 1.71V to 3.6V supply voltage. Accelerometers are an ideal choice for ultra-low-power applications and have advanced power-saving features. Features include low-power mode, auto wake-up function, and FIFO buffer that can be used to store data. This reduces the host processor loading and system power consumption.
