This document is an application note that describes the minimum hardware and software environment required to build an application around an STM8A 8-bit microcontroller device. It includes power supply, analog-to-digital converter (ADC), clock management, reset control and development, debugging tool support, STM8 software toolchain, and setting up the STM8 development environment.
This document serves as a guide for developers starting work with the STM8A family of 8-bit microcontrollers. It complements standard datasheets by detailing the specific hardware requirements, such as power supply configurations and clock management, necessary to create a functional development board.
The note provides detailed reference design schematics and component lists to assist in building an evaluation environment. Additionally, it covers the setup of the STM8 software toolchain, including instructions for installing tools like STVD and using debugging instruments such as STice.
| Operating voltage range | 3.0 V to 5.5 V external source |
|---|---|
| Internal digital supply voltage | 1.8 V nominal target output |
| Minimum external capacitor value | 470 nF |
The board must provide power supply, clock management, reset management, and debugging tool support via a Single wire interface module (SWIM) connector.
The minimum value for the external capacitor connected via the Vcap pin is 470 nF.
