The STM32F030x microcontrollers integrate a high-performance ARM Cortex™-M0 32-bit RISC core running at 48 MHz, high-speed embedded memory, and a wide range of enhanced peripherals and I/Os. All devices offer standard communication interfaces, a 12-bit ADC, up to six general-purpose 16-bit timers, and an advanced control PWM timer. The STM32F030x microcontrollers operate in the -40 to +85°C temperature range with a supply voltage between 2.4 and 3.6 V.

STM32F030x microcontrollers are suitable for application control and user interface, handheld devices, A/V receivers, and digital TVs, PC peripherals, gaming consoles, e-bikes, consumer appliances, printers, scanners, alarm systems, video walkie-talkies, and more, and HVAC.
