The STM32 L1 series now hosts an entry level line, the STM32L100
The latest addition to ST’s STM32 L1 series, the STM32L100, is the perfect fit for applications that require a minimum processing power and ultra-low power consumption, all at a budget price.
The STM32L100 comes with a real-time clock, 16-bit timers, communication interfaces (SPI, I²C, USART, USB), analog peripherals, including a 12-bit ADC, and a LCD driver (up to 8x28 segments).
The STM32L100 Value line operates from 1.8 to 3.6 V and is available in the -40 to +85 °C temperature range.
All STM32 L1 series share the same architecture with the same memory mapping and are fully pin-to-pin compatible.
