The recommended operating voltage range for SC80C31BCCN40 is 4.5V to 5.5V, with a typical voltage of 5V.
The reset pin (RST) should be pulled high during power-up and power-down to ensure proper reset. A 10kΩ pull-up resistor and a 100nF capacitor to ground are recommended.
The maximum clock frequency supported by SC80C31BCCN40 is 12 MHz, but it can be overclocked up to 16 MHz with careful consideration of power consumption and thermal management.
The UART serial communication interface can be configured using the SCON (Serial Control) register. Set the SM0 and SM1 bits to select the serial mode, and configure the baud rate using the Baud Rate Generator (BRG) registers.
The EA pin is used to enable or disable external memory access. When EA is low, the microcontroller accesses external memory; when EA is high, the microcontroller accesses internal memory.
