SiM3L1xx 低功耗 MCU

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.

自主型外设降低了 50 MHz ARM® Cortex®-M3 CPU 负荷,进一步降低了处理时间和功耗。Full RAM and state retention enable 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. 增强型 Precision32 工具可通过估算功耗、提供配置向导来简化开发过程,以实现低功耗。
