The ST72C215G2B6 can operate up to 16 MHz with an external clock source, but the internal oscillator can only reach up to 8 MHz.
The ST72C215G2B6 consumes approximately 10 μA in sleep mode, making it suitable for battery-powered applications.
No, the internal oscillator is not suitable for generating a stable clock signal for the UART. An external clock source is recommended for UART communication.
The I/O pins of the ST72C215G2B6 can source up to 20 mA of current, but it's recommended to limit the current to 10 mA to ensure reliable operation.
No, the ST72C215G2B6 is a 3.3V device and is not compatible with 5V logic levels. Level shifters or voltage dividers may be required to interface with 5V devices.
