General Description

The HT45F0063 is a Flash Memory type 8-bit high performance RISC architecture microcontroller dedicated for use in multi-channel RGB dimming LED control 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.

One extremely flexible Timer Module provides timing, compare match output and PWM generation functions. Communication with the outside world is catered for by including a fully integrated I2 C  interface function, which provides designers with a means of easy communication with external  peripheral hardware. Protective features such as an internal Watchdog Timer and Low Voltage Reset  function coupled with excellent noise immunity and ESD protection ensure that reliable operation is  maintained in hostile electrical environments.

A full choice of internal high speed and low speed oscillator functions is provided including two  fully integrated system oscillator which require 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.

Circuits specific to RGB dimming applications are also fully integrated within the device, which  include COM scanning output driver, PWM function, constant current LED driver and cascading  transceiver interface. The inclusion of flexible I/O programming features, Time-Base function  along with many other features ensure that the device will find excellent use in applications such as  breathing lights, christmas lights, light strips and mood lights etc.
