HT45F0084
Cord-free Vacuum Cleaner ASSP Flash MCU
General Description
The device is a Flash Memory type 8-bit high performance RISC architecture microcontroller.
Offering users the convenience of Flash Memory multi-programming features, this 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 true 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, an over current protection function,
an over voltage protection function, an under voltage protection function, and an auto-adjust PWM
Duty function. Multiple and 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.
A full choice of HIRC and LIRC 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 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 applications such as electronic metering,
environmental monitoring, handheld instruments, household appliances, electronically controlled
tools, motor driving in addition to many others.
