AN2555 - Application note

Modified features

7/33

1.3.1

Hardware impacts

None.

1.3.2

Software impacts

The mapping of the application, the programming and erasing routines are impacted.

1.4

A/D converter

In the ST10F276Z5, the Analog Digital converter has been re-designed (compared to the A/D converter

in the ST10F269Zx). The ST10F276Z5 still provides an Analog / Digital Converter with 10-bit resolution

and an on-chip sample & hold circuit.

1.4.1

Hardware / Software impact: conversion timing control

The A/D Converter in the ST10F276Z5 is not fully compatible to that in the ST10F269Zx (timing and

programming model).
