The maximum clock frequency for the ST72C124J2T6 is 16 MHz, but it can be overclocked to 20 MHz with some limitations.
The oscillator can be configured using the OSCXCF and OSCXCF2 registers. The oscillator frequency can be selected by setting the appropriate values in these registers.
The power consumption of the ST72C124J2T6 varies depending on the operating mode and frequency. In active mode, the typical current consumption is around 10 mA at 16 MHz, and in sleep mode, it's around 10 μA.
The ADC on the ST72C124J2T6 is a 10-bit successive approximation ADC. It can be configured using the ADCM and ADCS registers. The ADC clock frequency should be set to 1/4 of the system clock frequency.
Yes, the ST72C124J2T6 can operate with a 3.3V power supply, but the maximum clock frequency should be limited to 12 MHz to ensure reliable operation.
