13.9 CONTROL PIN CHARACTERISTICS
13.9.1 Asynchronous RESET Pin
TA = -40°C to 85°C, unless otherwise specified
Notes:
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 13.2.2 on page 130 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.
