Porting an application from the ST10F269Zx to the ST10F273Z4
Introduction
The ST10F273Z4 is a derivative of the STMicroelectronics ST10 family of 16-bit single-chip
CMOS microcontrollers and is functionally upwardly compatible with the ST10F269Zx.
The goal of this document is to highlight the differences between the ST10F269Zx and the
ST10F273Z4 devices. It is intended for hardware or software designers who are adapting an
existing application based on the ST10F269Zx to the ST10F273Z4.
This document first presents the modified functionalities of the ST10F273Z4, and then
presents the new functionalities before looking at the modified and the new registers. In
each section of the document, differences with the ST10F269Zx that may have an impact
are stressed and some advice is given on how best to handle these differences and impacts.
