In summary, the Precision32™ ARM Cortex®-M3 family of microcontrollers from Silicon Labs provides fundamental advantages over the competition at a lower total solution cost. The Precision32 family offers features such as crystal-less USB operation with a 5 V internal regulator. There are six high drive I/Os capable of directly driving LEDs, small motors, power FETs, and buzzers. The precision analog is tested and guaranteed over temperature and voltage. Customizable pin-out and peripherals ease layout and can reduce the amount of PCB area required because there are no pin conflicts. Overall power consumption is reduced in low power sleep and active modes. World-class tools are available to help speed development and reduce time to market.
