NRST pin
A single active low pin, NRST, is provided to reset the system. This pin has a Schmitt
triggered input.
To afford good noise immunity and resistance to switch bounce, the pin is filtered with the
Reset Filter module and generates the reset source RSTB to the Reset Generation module.
Table 41.
Absolute maximum ratings (electrical sensitivity)
Based on three different tests (ESD, LU) using specific measurement methods, the device is
stressed in order to determine its performance in terms of electrical sensitivity.
Electrostatic discharge (ESD)
Electrostatic discharges (a positive then a negative pulse separated by 1 second) are
applied to the pins of each sample according to each pin combination. The sample size
depends on the number of supply pins in the device (3 parts × (n+1) supply pins). This test
conforms to the JESD22-A114/C101 standard.

Static latch-up
Two complementary static tests are required on six parts to assess the latch-up
performance:
●
●
These tests are compliant with EIA/JESD 78A IC latch-up standard.
