These devices are Flash Memory type 8-bit high performance RISC architecture microcontrollers with a USB interface and integrated RGB control functions. Specifically designed for applications that interface directly to analog signals, require a USB interface and also are required to drvie RGB LEDs, they offer users the convenience of Flash Memory multi-programming features. The devices also include a wide range of other useful 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 and two comparators. Multiple and extremely flexible Timer Modules provide timing, pulse generation and PWM generation functions. There are multiple PWM outputs specially provided for multiple RGB LED applications. Communication with the outside world is catered for by including fully integrated SPI, I2C, UART and USB interface functions, four popular interfaces which provide designers with a means of easy communication with external peripheral hardware. 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. The external interrupt can be triggered with falling edges or both falling and rising edges.

A full choice of external, internal high and low oscillators is provided including two fully integrated system oscillators which require no external components for their 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 along with many other features ensure that the devices will find specific excellent use in a wide range of application possibilities such as sensor signal processing, motor driving, industrial control, consumer products, subsystem controllers, etc.

These devices are fully supported by the Holtek range of fully functional development and programming tools, providing a means for fast and efficient product development cycles.
