13.9 CONTROL PIN CHARACTERISTICS
13.9.1 Asynchronous RESET Pin
TA = -40 to +85°C unless otherwise specified
Figure 90. Typical IPU on RESET pin
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 and the sum of IIO
(I/O ports and control pins) must not exceed IVSS.
3. 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.
