General Description

The HT45F0062 device 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 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 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.
