Single-chip 16/32-bit microcontrollers
7. Limiting values
[1] The following applies to the Limiting values:
a) This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive
static charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated
maximum.
b) Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to V
SS
unless
otherwise noted.
[2] Including voltage on outputs in 3-state mode.
[3] Not to exceed 4.6 V.
[4] The peak current is limited to 25 times the corresponding maximum current.
[5] Dependent on package type.
[6] Human body model: equivalent to discharging a 100 pF capacitor through a 1.5 k series resistor.
Table 5. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
