Applications
* with very few low-cost external components. A 32kHz crystal time base for the entire system and internal battery-backup support for RAM and RTC further reduce system cost. Maximum design flexibility is supported with multiple UARTs, I2C, a powerfail comparator, a 5V LCD charge pump, up to 22 DIO pin
