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 I2C 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.
