The STM32F3x8 low‑voltage 1.8 V line

The STM32F3x8 line operates at 1.8 V ± 8%. It is well suited for use in portable consumer applications such as smartphones, accessories and

media devices. Designers can take advantage of the same features as the STM32F3 series with no compromise or degradation in processing

performance when operating at a lower voltage. The combination of 1.8 V digital supply voltage and an independent analog domain is an

advantage in heterogeneous system architectures, leading to simplified system design and connected cost savings. The STM32F3x8 devices are

ideal low‑voltage companion microcontrollers, allowing to maintain a wide analog dynamic range.
