The recommended operating voltage range for the M41ST87WMX6TR is 2.7V to 5.5V.
The crystal oscillator circuit requires a crystal resonator with a frequency of 32.768 kHz, and the X1 and X2 pins should be connected to the crystal resonator. Additionally, the C1 and C2 capacitors should be connected between the X1 and X2 pins and ground, with values of 10-22 pF.
The M41ST87WMX6TR supports a maximum clock frequency of 32.768 kHz.
To configure the M41ST87WMX6TR for low-power operation, set the PD bit in the Control Register to 1, and ensure that the oscillator is stopped by setting the ST bit to 0. Additionally, reduce the clock frequency and disable any unnecessary peripherals.
The RST pin is an active-low reset input that resets the device when pulled low. It can be connected to a push-button or a reset generator IC.
