Application note

Porting an application from the ST10F269Zx to the ST10F272Z2

Introduction

The ST10F272Z2 is a new member of the STMicroelectronics ST10 family of 16-bit single-

chip CMOS microcontrollers. It is functionally upward compatible with the ST10F269Zx.

The goal of this document is to highlight the differences between ST10F269Zx and

ST10F272Z2 devices. It is intended for hardware or software designers who are adapting an

existing application based on the ST10F269Zx to the ST10F272Z2.

This document presents the ST10F272Z2’s modified functionalities and the new ones, and

goes on to describe the modified and the new registers. For each part, the differences with

the ST10F269Zx that may have an impact when replacing the ST10F269Zx by the

ST10F272Z2 are stressed and some advice is given on the way they can be handled.
