The HT45F0060 device is an ASSP MCU dedicated for use in RGB dimming LED control applications. It is a Flash Memory type 8-bit high performance RISC architecture microcontroller. 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.

Multiple extremely flexible Timer Modules provide timing, compare match output and PWM generation functions. 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 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 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.
