STM8L101 is our entry-level line in the STM8L ultra-low-power family and is the most affordable line of low-voltage microcontrollers offering basic functionalities with low-power performance.

The devices include up to 8 Kbytes of Flash memory with up to 1.5 Kbytes of SRAM. Based on our STM8 16 MHz core, these MCUs also include the rich set of peripherals of more advanced lines with USART, SPI, I²C interfaces, a full set of timers, comparators, and other features. Available in 20- to 32-pin packages, different configurations can be selected to fit application needs at the most affordable price.
