STM32L151VBH6 Ultra-low-power 32-Bit ARM Cortex-M3 Microcontroller MCU with 128KB Flash Memory

STM32L151VBH6 is an ultra-low-power 32-bit Arm Cortex-M3 Microcontroller that incorporates USB connectivity with a high-performance ARM® Cortex®-M3 32-bit RISC core operating at 32 MHz frequency (33.3 DMIPS). It features a memory protection unit (MPU), high-speed embedded memories (Flash memory up to 128 Kbytes and RAM up to 16 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses.

The device offers a 12-bit ADC, 2 DACs and 2 ultra-low-power comparators, six general-purpose 16-bit timers and two basic timers, which can be used as time bases.
