This application note describes how to use the high-density performance line STM32F20xxx/21xxx product families and describes the minimum hardware resources required to develop an STM32F20xxx/21xxx application. Detailed reference design schematics are also contained in this document with descriptions of the main components, interfaces and modes.
This document is intended for system designers requiring an overview of development board features for the high-density performance line STM32F20xxx/21xxx product families. It describes the minimum hardware resources required to develop an application, including power supply schemes, clock management, boot configuration, and debug management.
The device requires a supply voltage between 1.8 V and 3.6 V, except WLCSP packages which require 1.65 V to 3.6 V.
