STMicroelectronics ARM Cortex M0+, STM32 Microcontroller, 48MHz, 128 kbyte Flash, 28-Pin UFQFPN

The STMicroelectronics mainstream microcontrollers are based on high-performance Arm Cortex-M0+ 32-bit RISC core operating at up to 48 MHz frequency. Offering a high level of integration, they are suitable for a wide range of applications in consumer, industrial and appliance domains and ready for the Internet of Things (IoT) solutions. The devices incorporate a memory protection unit (MPU), high-speed embedded memories (24 Kbytes of SRAM and up to 128 Kbytes of flash program memory with read and write protection, proprietary code protection, and securable area), DMA, an extensive range of system functions, enhanced I/Os, and peripherals. The devices offer standard communication interfaces (two I2Cs, two SPI / one I2S, one full-speed USB, and two USARTs), one 12-bit ADC (2.5 MSps) with up to 19 channels, a low-power RTC, an advanced control PWM timer, four general-purpose 16-bit timers, a 32-bit general-purpose timer, two watchdog timers, and a SysTick timer.
