or RC
OSC1, OSC2 are connected to an RC network or Crystal (determined by op-
tions) for the internal system clock. In the case of RC operation, OSC2 is the
output terminal for 1/4 system clock.
* All pull-high resistors are controlled by an option bit.
Absolute Maximum Ratings
Supply Voltage ...........................VSS-0.3V to VSS+6.0V
Input Voltage..............................VSS-0.3V to VDD+0.3V
Storage Temperature ............................-50°C to 125°C
Operating Temperature...........................-40°C to 85°C
Note: These are stress ratings only. Stresses exceeding the range specified under ²Absolute Maximum Ratings² may
cause substantial damage to the device. Functional operation of this device at other conditions beyond those
listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliabil-
ity.
