STM32L151VBT6 [STMicroelectronics]

STM32L151VBT6 Description

The STM32L151VBT6A is an ultra-low-power STM32 L1 series 32-bit Microcontroller that combines the connectivity power of the USB with the high-performance ARM Cortex-M3 RISC core operating at 32MHz (33.3 DMIPS). It includes a memory protection unit (MPU), high-speed embedded memories (Flash memory up to 128kB and RAM up to 16KB), and a plethora of enhanced I/Os and peripherals linked by two APB buses. There is one 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 in the devices. The device has both standard and advanced communication interfaces, including two I2Cs, two SPIs, three USARTs, and a USB port.
