1 - INTRODUCTION

The ST10F269 is a new derivative of the STMicroelectronics ST10 family of 16-bit single-chip CMOS

micro-controllers. It is upward compatible with the ST10F168.

The goal of this document is to enlighten the differences between the ST10F269 and ST10F168 and is

intended for hardware or software designers who are adapting an existing application based on the

ST10F168 to the ST10F269.

This document will present the modified functionalities of the ST10F269, then the new ones before

looking at the modified and the new registers. For each part, the differences with the ST10F168 that may

be impacting will be stressed and some advice on the way they can be handled will be given.
