4 / 100 page  Pin Name I/O Configuration Option Description PC3/OSC3 PC4/OSC4 I/O RTC OSC Bidirectional 2-line I/O. Software instructions determine if the pins are CMOS outputs or Schmitt Trigger inputs. A pull high resistor can be connected to each pin using the PCPU register. Configura- tion options determine if the pins are to be used as oscillator pins or I/O pins. If configuration options select oscillator pins, the pins are connected to a 32768Hz crystal oscillator. VDD/AVDD ¾¾ Positive power supply/analog positive power supply. VSS/AVSS ¾¾ Negative power supply, ground/analog negative power supply, ground Note: The Pin Description table represents the largest package available, therefore some of the pins and functions may not be available on smaller package types. Absolute Maximum Ratings Supply Voltage ...........................VSS -0.3V to VSS+6.0V Storage Temperature ............................ -50°Cto125°C Input Voltage..............................VSS -0.3V to VDD+0.3V Operating Temperature........................... -40°Cto85°C IOL Total ................................................................80mA IOH Total.............................................................. -80mA Total Power Dissipation .....................................500mW 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 reliability. D.C.
