For designers of STM8S microcontroller applications, this application note provides migration and compatibility guidelines. It explains how to migrate from an existing STM8S-based design to any one of the 20+ other microcontroller types in the STM8S family. The document lists the vital aspects that need to be addressed.
The document serves as a guide for engineers designing applications based on the STM8S family of 8-bit microcontrollers. It addresses the need to replace one microcontroller type with another due to growing product requirements, memory needs, or cost reduction objectives.
The note is structured into three main sections: an overview of the STM8S family compatibility architecture, a checklist for planning migration cases, and a detailed block-by-block analysis of hardware features.
To help designers analyze steps needed to migrate from an existing STM8S-based design to another microcontroller type in the family.
General STM8S knowledge is required, which can be learned from the family reference manual and datasheets.
The family includes the Performance line (STM8S208 and STM8S207) and the Access line (STM8S105 and STM8S103).
