Handheld Product Flash MCU with Two Cell Li-Batteries
General Information
The device is a Flash Memory 8-bit high performance RISC architecture microcontroller, specifically designed for handheld products with two cell li-batteries.
For memory features, the Flash Memory offers users the convenience of multi-programming features. Other memory includes an area of RAM Data Memory. Analog features include a multichannel 12-bit A/D converter. Multiple extremely flexible Timer Modules provide 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 device also includes 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 optimize microcontroller operation and minimize power consumption.
The inclusion of flexible I/O programming features, Time-Base functions along with many other features ensure that the device will find excellent use in different handheld products with two cell libatteries.
Circuitry specific to handheld products with two cell li-batteries is also fully integrated within the device. These include functions such as LDO, high voltage output, over voltage protection and over current protection. These features combine to ensure that a minimum of external components is required to implement handheld products with two cell li-batteries, providing the benefits of reduced component counts and reduced circuit board areas.
