Note:
All I/O Ports are configured in bidirectional weak pull-up mode with no DC load, unless otherwise specified, external clock is driven by a
square wave.
(1) Unless otherwise stated, typical data are based on VDD= 5V. They are only reported for design guide lines not tested in production.
(2) Current consumption to be added to IDDRUN when the FLASH memory is accessed.
(3) Value guaranteed by product characterization, not tested in production.
(4) Current consumption to be added to IDDLPWFI when the FLASH memory is in stand-by mode.
(5) The I/Os draw a transient current from VDD when an input takes a voltage level in between VSS and VDD. This current is 0 for VIN<0.3V
or VIN>VDD-0.3V, it typically reaches its maximum value when VIN is approximatively at VDD/2.
