11 Electrical Characteristics
This section contains electrical specification tables and reference timing diagrams.
1. Permanent damage can occur if maximum ratings are exceeded. Exposure to voltages or currents in excess
of recommended values affects device reliability. Device modules may not operate normally while being ex-
posed to electrical extremes.
2. Although sections of the device contain circuitry to protect against damage from high static voltages or elec-
trical fields, take normal precautions to avoid exposure to voltages higher than maximum-rated voltages.
3. This parameter is periodically sampled rather than 100% tested.
4. Input must be current limited to the value specified. To determine the value of the required current-limiting re-
sistor, calculate resistance values for positive and negative clamp voltages, then use the larger of the two val-
ues.
5. All functional non-supply pins are internally clamped to V
SS
for transitions below V
SS
. All functional pins except
EXTAL and XFC are internally clamped to V
DD
for transitions below V
DD
.
6. Power supply must maintain regulation within operating V
DD
range during instantaneous and operating max-
imum current conditions.
7. Total input current for all digital input-only and all digital input/output pins must not exceed 10 mA. Exceeding
this limit can cause disruption of normal operation.
8. V
FPE
must not be raised to programming level while V
DD
is below specified minimum value. V
FPE
must not be
reduced below minimum specified value while V
DD
is applied.
9. Flash EEPROM modules can be damaged by power-on and power-off V
FPE
transients. Maximum power-on
overshoot tolerance is 13.5 V for periods of less than 30 ns.
