The high-performance ARM? Cortex?-M3 32-bit RISC core operates at a frequency of 32 MHz (33.3 DMIPS) in the ultra-low-power STM32L100x6/8/B-A devices, along with a memory protection unit (MPU), high-speed embedded memories (Flash memory up to 128 Kbytes and RAM up to 16 Kbytes), and a wide variety of enhanced I/Os and peripherals connected to two APB buses.
A 12-bit ADC, two DACs, two ultra-low-power comparators, six general-purpose 16-bit timers, and two basic timers that can be used as time bases are all provided by each device. The STM32L100x6/8/B-A devices also include both conventional and cutting-edge communication interfaces, including up to two I2C and SPIs, three USARTs, and a USB.
