Electrical characteristics
— 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.
3.11.2 Electromagnetic interference (EMI)
The product is monitored in terms of emission based on a typical application. This emission test conforms to the IEC61967-1
standard, which specifies the general conditions for EMI measurements.
