STM8L Ultra-Low-Power Microcontrollers

STMicroelectronics STM8L Microcontrollers (MCUs) use a proprietary ultra-low leakage process and optimized architecture to provide high performance and ultra-low power consumption. The MCU, which includes the STM8L101xx and STM8L15xx, is based on the 8-bit STM8 core and is ideal for many applications with special care on power savings. The STM8L embeds up to 4 different ultra-low-power modes to offer users a high level of flexibility. STMicroelectronics STM8L MCUs offer a high level of integration and a compact footprint. The STM8L-DISCOVERY Board is ideal for evaluating the high-performance MCUs.
