Silicon Labs’ ultra low-power Precision32™ SiM3L1xx 32-bit microcontrollers (MCUs) feature significant peripheral and architectural innovations, including an integrated dc-dc converter that helps save power in active mode as well as a redesigned LCD controller that can reduce the power consumed by the LCD display.
Autonomous peripherals off-load the 50 MHz ARM® Cortex®-M3 CPU and further decrease processing time and power. Full RAM and state retention enables instantaneous code execution after waking up from sleep. Flash memory sizes range from 32 to 256 kB, and the MCUs come in packages as small as 5.5 mm x 5.5 mm. Enhanced Precision32 tools can simplify the development process by estimating power consumption and providing configuration guidance to achieve the lowest power.
