Silicon Labs’ new Precision32™ ARM Cortex®-M3 family of microcontrollers is poised to immediately capture significant market share by providing fundamental advantages over the competition at a lower total solution cost. The Precision32 family offers features other controllers do not have such as crystal-less USB operation with 5 V internal regulator to make USB easy and lower cost. There are six high drive I/Os that can directly drive LEDs, small motors, power FETs and buzzers. The precision analog is tested and guaranteed over temperature and voltage. Fully customizable pin-out and peripherals ease layout and can enable smaller packages due to the lack of pin conflicts. Low power in sleep and active modes reduces overall power consumption. Finally, the available world-class tools help speed development and reduce time to market.
