STM32L151RDT6TR

STM32L151RDT6TR is an ultra-low-power, Arm® Cortex®-M3 32bit MCU. The device offers three operational amplifiers, one 12bit ADC, two DACs, two ultra-low-power comparators, one general-purpose 32bit timer, six general-purpose 16bit timers, and two basic timers, which can be used as time bases. It also contains standard and advanced communication interfaces: up to two I²Cs, three SPIs, two I²S, one SDIO, three USARTs, two UARTs, and a USB. This device offers up to 34 capacitive sensing channels to simply add a touch-sensing functionality to any application. It also includes a real-time clock and a set of backup registers that remain powered in standby mode.
