The STM32F0x8 microcontrollers operate at 1.8V +/-8%. They are well suited to use in portable consumer applications such as smartphones, accessories and media devices, and allow designers to take advantage of the same features as the STM32F0 series with no compromise or degradation in processing performance when operating at lower voltage.

The combination of 1.8V digital supply voltage, a separate I/O voltage supply rail and an independent analog domain is an advantage in heterogeneous system architectures, leading to simplified system design and connected cost savings. The STM32F0x8 devices are ideal low-voltage companion microcontrollers, allowing to maintain a wide analog dynamic range or to directly connect USB devices.
