RTC

◆ Hardware automatic temperature compensation, meeting standard requirements for accuracy and power consumption, temperature compensation does not require CPU involvement.

◆ Temperature sensor: Temperature measurement accuracy within the range of -25 ℃ to 70 ℃ is ± 1 ℃

◆ RTC perpetual calendar and automatic temperature compensation circuit independently use VBAT pin power supply

◆ The typical value of VBAT domain power consumption is better than 1.5uA

◆ The temperature compensation time is less than 1ms, and the typical power consumption is 250 μ A. If it is turned on every 30 seconds, the average power consumption is 0.0083 μ A;

◆ RN8612 only supports resistance voltage division mode, while other series support ChargePUMP and optional built-in resistance column voltage division mode. Under the resistance column voltage division mode scheme, it is recommended to use a 6com/3V screen;

◆ If you need to support more segments, you can choose the 8COM 5V screen (charge pump mode); If lower display power consumption is required, a 6COM 3V screen (resistor series voltage division method) can be selected. The two are compatible in hardware, only requiring changes to the software configuration.
