STM32L151VET6

The STM32L151VET6 is an ultra-low-power STM32 L1 series 32-bit Microcontroller incorporates the connectivity power of the universal serial bus (USB) with the high-performance ARM Cortex-M3 RISC core operating at a frequency of 32MHz (33.3 DMIPS). It features a memory protection unit (MPU), high-speed embedded memories (Flash memory up to 512kB and RAM up to 80KB) and an extensive range of enhanced I/Os and peripherals connected to two APB buses. The devices offer two operational amplifiers, one 12-bit ADC, two DACs, two ultra-low-power comparators, one general-purpose 32-bit timer, six general-purpose 16-bit timers and two basic timers, which can be used as time bases. The device contain standard and advanced communication interfaces - two I²Cs, two I²Ss, three SPIs, three USARTs, two UARTs and an USB.
