AN3029 is an application note about the STM8L 8-bit microcontroller, which provides a detailed description of the STM8L 8-bit microcontroller's basic hardware and software environment, and is suitable for low density STM8L101x, medium density STM8L15x and high density STM8L15x/16x devices.
This document complements STM8L datasheets by detailing the necessary hardware and software setup for STM8L101x, STM8L15x, and STM8L15x/16x devices. It covers principal hardware components including power supply, analog-to-digital converter (ADC), clock management, and reset control, along with hardware recommendations.
The guide provides detailed reference design schematics and descriptions of main components. It also explains the STM8 development tools and software toolchain, which are common to STM8L, STM8S, and STM8A, and includes instructions on setting up the STM8 development environment.
| Power supply range | 1.65 V to 3.6 V |
|---|---|
| Internal regulator output | 1.8 V |
| Decoupling capacitor (Ceramic) | 100 nF |
The STMB8L can be supplied through a 1.65 V to 3.6 V external source.
It applies to low density STM8L101x, medium and medium+ density STM8L15x, and high density STM8L15x/16x devices.
The internal regulator has a nominal target output of 1.8 V.
