Data based on characterization results, not tested in production

VOL

Output low level voltage(2)

The IIO current sunk must always respect the absolute maximum rating specified in Table 62: Current

characteristics and the sum of IIO (I/O ports and control pins) must not exceed IVSS.

RON

Pull-up equivalent resistor(3)

The RON pull-up equivalent resistor is based on a resistive transistor. Specified for voltages on RESET pin

between VILmax and VDD.

VIN =VSS

VDD =5V

time(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.
