Figure 16.8 Port pin Equivalent Circuit
16.10.2 Output Driving Current
Operating Conditions: VDD=2.8 V to 5.5 V, TA=25
° C, unless otherwise specified.
Table 16.14 Output Voltage Levels for class B pins3)
Notes:
1. The IIO sunk current must always respect the absolute maximum rating specified in Section 16.2 and
the sum of IIO (I/O ports and control pins) must not exceed IVSS. Data from characterization; not tested
in production.
2. The IIO sourced current must always respect the absolute maximum rating specified in Section 16.2 and
the sum of IIO (I/O ports and control pins) must not exceed IVDD. Data from characterization; not tested
in production.
3. Class A indicates an 8 mA driving capability of the output buffer while Class B indicates a 4 mA driving
capability of the output buffer. See General Description chapter for a complete description of class A
and B pins for every package.
