Electrical characteristics
Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical application
environment and simplified MCU software. It should be noted that good EMC performance is highly
dependent on the user application and the software in particular.
Therefore it is recommended that the user applies EMC software optimization and prequalification tests
in relation with the EMC level requested for his application.
Software recommendations
The software flowchart must include the management of runaway conditions such as:
Prequalification trials
Most of the common failures (unexpected reset and program counter corruption) can be reproduced by
manually forcing a low state on the RESET pin or the Oscillator pins for 1 second.
To complete these trials, ESD stress can be applied directly on the device, over the range of specification
values. When unexpected behavior is detected, the software can be hardened to prevent unrecoverable
errors occurring (see application note AN1015).
