BP45F4NB/BP45FH4NB

General Information

The devices are Flash Memory 8-bit high performance RISC architecture microcontrollers, specifically designed for Power Bank applications.

For memory features, the Flash Memory offers users the convenience of multi-programming features. Other memory includes an area of RAM Data Memory. By using the In Application Programming technology, users have a convenient means to directly store their measured data in the Flash Program Memory as well as having the ability to easily update their application programs.

Analog features include a multi-channel 12-bit A/D converter, an USB charge/discharge auto detection function and a LDO regulator. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. Communication with the outside world is catered for by including fully integrated SPI, I²C and UART interface functions, these popular interfaces which provide designers with a means of easy communication with external peripheral hardware. 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 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 devices will find excellent use in different power bank applications.

Circuitry specific to Power Bank applications is also fully integrated within the devices. These include functions such as over/under voltage protection, over current protection and USB auto detection. These features combine to ensure that a minimum of external components is required to implement Power Bank applications, providing the benefits of reduced component counts and reduced circuit board areas.
