Electromagnetic compatibility (EMC) characteristics
Susceptibility tests are performed on a sample basis during product characterization.
4.12.1
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 apply 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:
— Corrupted program counter
— Unexpected reset
— Critical data corruption (control registers...)
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. When unexpected behavior is detected, the
software can be hardened to prevent unrecoverable errors occurring.
4.12.2
Electromagnetic interference (EMI)
The product is monitored in terms of emission based on a typical application. This emission test conforms to the IEC 61967-1
standard, which specifies the general conditions for EMI measurements.
4.12.3
Absolute maximum ratings (electrical sensitivity)
Based on two different tests (ESD and LU) using specific measurement methods, the product is stressed in order to determine
its performance in terms of electrical sensitivity.
