The recommended operating voltage range for the ST62T01CM3 is 2.7V to 5.5V.
To configure the ST62T01CM3 for low-power mode, set the PWRMODE bit in the Power Management Register (PMR) to 1. This will put the device in low-power mode, reducing power consumption.
The maximum clock frequency supported by the ST62T01CM3 is 32 MHz.
To use the internal oscillator on the ST62T01CM3, set the OSCEN bit in the Oscillator Control Register (OCR) to 1. This will enable the internal oscillator, and the device will use it as the clock source.
The WAKEUP pin on the ST62T01CM3 is used to wake up the device from low-power mode. When the WAKEUP pin is asserted, the device will exit low-power mode and resume normal operation.
