The recommended operating voltage range for the ST62T25CB6 is 2.2V to 5.5V.
The oscillator frequency can be configured using the OSCCAL register. The oscillator frequency can be set to 4MHz, 8MHz, or 16MHz by writing the appropriate value to the OSCCAL register.
The maximum clock frequency supported by the ST62T25CB6 is 16MHz.
The internal RC oscillator can be enabled by setting the OSCEN bit in the OSCCAL register. The oscillator frequency can be trimmed using the OSCTRIM register.
The power consumption of the ST62T25CB6 in sleep mode is typically around 10uA at 3V and 25°C.
