Atmel Corporation has just announced a new range of AVR microcontrollers that will be able to combine USB controller and high performance analog features. Both the ATmega16U4 and ATmega32U4 are able to reduce system cost in battery powered devices like gaming accessories. Currently, modern batteries require sophisticated algorithms that accelerate and optimize charging, and USB adds on additional constraints on the battery charging since both voltage and maximum current are limited. AVR’s new devices enable an optimized battery charging combined with USB functions. The analog to digital converter will be able to use sense motion or pressure in the end application, while the high-speed PWM is ideal for low cost motor control.
