Electrical characteristics
All I/Os are CMOS and TTL compliant (no software configuration required), their
characteristics consider the most strict CMOS-technology or TTL parameters:
●
For V :
IH
–
–
if V is in the [2.00 V - 3.08 V] range: CMOS characteristics but TTL included
DD
if V is in the [3.08 V - 3.60 V] range: TTL characteristics but CMOS included
DD
●
For V :
IL
–
–
if V is in the [2.00 V - 2.28 V] range: TTL characteristics but CMOS included
DD
if V is in the [2.28 V - 3.60 V] range: CMOS characteristics but TTL included
DD
Output driving current
The GPIOs (general purpose input/outputs) can sink or source up to +/-8 mA, and sink
+20 mA (with a relaxed V ).
OL
In the user application, the number of I/O pins which can drive current must be limited to
respect the absolute maximum rating specified in Section 5.2:
●
The sum of the currents sourced by all the I/Os on V
plus the maximum Run
DD,
consumption of the MCU sourced on V
cannot exceed the absolute maximum rating
DD,
I
(see Table 8).
VDD
●
The sum of the currents sunk by all the I/Os on V plus the maximum Run
SS
consumption of the MCU sunk on V cannot exceed the absolute maximum rating
SS
I
(see Table 8).
VSS
Output voltage levels
Unless otherwise specified, the parameters given in Table 46 are derived from tests
performed under ambient temperature and V supply voltage conditions summarized in
DD
Table 10. All I/Os are CMOS and TTL compliant.
