General Description

The deivces are a Flash Memory type 8-bit high performance RISC architecture microcontroller  specially designed for ultra-low voltage especially one battery applications.

For memory features, the Flash Memory offers users the convenience of multi-programming  features. Other memory includes an area of RAM Data Memory as well as an area of true EEPROM  memory for storage of non-volatile data such as serial numbers, calibration data etc.

Single Timer Module provides timing, pulse generation and PWM generation functions. Protective  features such as an internal Watchdog Timer, Low Voltage Reset and Low Voltage Detector coupled  with excellent noise immunity and ESD protection ensure that reliable operation is maintained in  hostile electrical environments.

The devices also include fully integrated high and low speed oscillators which require no external  components for their implementation. The ability to operate and switch dynamically between a range  of operating modes using different clock sources gives users the ability to optimise microcontroller  operation and minimise power consumption.

These devices provide a power switch function, which is used to switch the VDD1 or VDD2 voltage as  MCU power supply VDD, where the VDD1 can be battery or solar output, while the VDD2 may be NFC  Havesting energy output. The inclusion of flexible I/O programming features, Time Base function,  LCD driver function along with many other features ensure that the devices will find excellent use in  applications such as solar energy storage display card and so on.
