HT45F5V
SPWM Inverter Output-end Flash MCU
General Information
The HT45F5V is an ASSP MCU specifically designed for SPWM inverter output-end 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 as well as an area of EEPROM memory for storage of non-volatile data such as serial numbers, calibration data etc.
Analog features include a multi-channel 12-bit A/D converter, a sine wave PWM generator, an AC power detector. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. A UART module is also contained in the device. It can support applications such as data communication networks between microcontrollers, low-cost data links between PCs and peripheral devices, portable and battery operated device communication, etc. 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. With regard to power, the protection functions also include Over Current Protection and Over Voltage Protection.
A full choice of external and internal oscillator functions are provided including a fully integrated system oscillator which requires no external components for its 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 inclusion of flexible I/O programming features, Time-Base functions along with many other features ensure that the device will find excellent use in SPWM inverter output-end application area.
