HT45F9160
Power Delivery Flash MCU
General Information
The device is an A/D type Flash Memory 8-bit high performance RISC architecture microcontroller, specifically designed for PD 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 as well as an area of true EEPROM memory for storage of non-volatile data such as serial number, calibration data, etc. 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 an operational amplifier current detection function. 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, UART or I2C (Master/Slave mode) 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 device also includes fully integrated high and low 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.
The device integrates USB Power Delivery (PD) PHY communication protocols and is compliant with USB PD 3.1/PPS specification. The inclusion of flexible I/O programming features, Time-Base functions, a 16-bit MDU, a CRC along with many other features ensure that the device will find excellent use in different PD Power Bank applications.
