The STM32L100RBT6 ultra-low-power device combines the connectivity of the Universal Serial Bus (USB) with a high-performance ARM® Cortex®-M3 32-bit RISC core running at 32 MHz (33.3 DMIPS), a Memory Protection Unit (MPU), high-speed embedded memory (up to 128 KB of flash memory and up to 10 KB of RAM), and a variety of enhanced I/O and peripherals connected to two APB buses.

The STM32L100RBT6 provides a 12-bit ADC, 2 DACs and 2 ultra-low-power comparators, six general-purpose 16-bit timers, and two basic timers used as time bases, as well as a real-time clock with sub-second counting and A set of backup registers that remain powered in standby mode.

The STM32L100RBT6 devices operate from a 1.8 to 3.6 V supply. They are suitable for a temperature range of -40 to +85 °C. It comes in a 64-pin package. They are making it widely used in medical and handheld devices, PC peripherals, wired and wireless sensors, etc.
