I/O PORT PIN CHARACTERISTICS (Cont’d)
Figure 72. Typical VDD-VOH vs. VDD (high sink port)
12.9 CONTROL PIN CHARACTERISTICS
12.9.1 Asynchronous RESET Pin
Subject to general operating conditions for VDD, fCP, and TA unless otherwise specified.
Notes:
1. Unless otherwise specified, typical data are based on TA=25°C and VDD=5V, not tested in production.
2. Data based on characterization results, not tested in production.
3. Hysteresis voltage between Schmitt trigger switching levels. Based on characterization results, not tested.
4. The IIO current sunk must always respect the absolute maximum rating specified in Section 12.2 and the sum of IIO (I/
O ports and control pins) must not exceed IVSS.
5. The RON pull-up equivalent resistor is based on a resistive transistor (corresponding ION current characteristics de-
scribed in Figure 73). This data is based on characterization results, not tested in production.
6. To guarantee the reset of the device, a minimum pulse has to be applied to RESET pin. All short pulses applied on
RESET pin with a duration below th(RSTL)in can be ignored.
