Holtek Releases New USB Controlled Red-Green-Blue LED Microcontroller
The new Microcontroller can control up to 128 RGB LEDs with constant current source and USB interface
With a focus on the colour RGB LED product application area, Holtek is delighted to announce the
release of its new USB Flash MCU, the HT66FB576. With its USB interface, the device is not only used in general computer peripheral and
consumer product applications, but with its integrated constant current source together with 48 PWM outputs,
it has the ability to control up to 128 RGB LEDs in a matrix scan configuration. The RGB LED colour change possibilities
can implement breathing effects using the fully internal hardware circuits. This makes this highly functionally integrated MCU
suitable for use in colour RGB LED products such as RGB Gaming Keyboards, RGB Gaming Mice, RGB LED Speakers etc.
By using this device the need for external PWM components is eliminated resulting in lower costs and
reduced product development times.
