1.
Data based on characterization results, not tested in production
2.
The IIO current sunk must always respect the absolute maximum rating specified in Section Table 66. on page 144 and the
sum of IIO (I/O ports and control pins) must not exceed IVSS.
3.
The RON pull-up equivalent resistor is based on a resistive transistor. Specified for voltages on RESET pin between VILmax
and VDD
4.
To guarantee the reset of the device, a minimum pulse has to be applied to the RESET pin. All short pulses applied on
RESET pin with a duration below th(RSTL)in can be ignored.
