Power Bank Flash MCU

General Description

The device is a Flash Memory 8-bit high performance RISC architecture microcontroller,

speciﬁcally designed for Power Bank applications. Oﬀering users the convenience of Flash Memory

multi-programming features, the device also includes a wide range of functions and features. Other

memory includes an area of RAM Data Memory.

Analog features include a multi-channel 12-bit A/D converter. Two 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 power bank applications.

Circuitry specific to Power Bank applications is also fully integrated within the device. These

include functions such as over voltage protection and over current protection. 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.
