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 pre
qualification 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 NRST 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).
Electromagnetic Interference (EMI)
The electromagnetic field emitted by the device is monitored while a simple application is
executed (toggling 2 LEDs through the I/O ports). This emission test is compliant with
IEC61967-2 standard which specifies the test board and the pin loading.
