APPLICATION NOTE

UPGRADING FROM ST625X/6XB TO ST625X/6XC

by Microcontroller Application Team

INTRODUCTION

As part of a process of continuous improvement, STMicroelectronics has replaced all

ST62T5XB and ST62T6XB devices by ST62T5XC and ST62T6XC.

This opportunity was taken to include new features such as the Low Voltage Detector (LVD)

for safe reset, the Oscillator Safeguard (OSG) and a new RC oscillator.

This application note details these new features and draws attention to some precautions that

it is mandatory to take when upgrading an application developed with B revision to C revision

devices. The first part of the document is related to the silicon itself and the second one to the

development tools.
