Electrical characteristics

Figure 39: Typical NRST pull-up current vs VDD @ 4 temperatures

The reset network shown inthe following figure protects the device against parasitic resets.

The user must ensure that the level on the NRST pin can go below the VIL max. level specified

in the I/O port pin characteristics section. Otherwise the reset is not taken into account

internally.

SPI serial peripheral interface

Unless otherwise specified, the parameters given in the following table are derived from tests

performed under ambient temperature, fMASTER frequency and VDD supply voltage conditions.

tMASTER = 1/fMASTER.

Refer to I/O port characteristics for more details on the input/output alternate function

characteristics (NSS, SCK, MOSI, MISO).
