Ambient temperature under bias......................................................................................................-55°C to +125°C
Storage temperature ....................................................................................................................... -65°C to +150°C
Voltage on any pin with respect to VSS (except VDD, MCLR, and RA4) ......................................... -0.3V to (VDD + 0.3V)

Maximum current out of VSS pin .........................................................................................................................300 mA

Maximum output current sunk by any I/O pin........................................................................................................25 mA

Maximum current sunk by all ports .....................................................................................................................200 mA

Note 1: Power dissipation is calculated as follows:Pdis = VDD x {IDD IOH} + {(VDD VOH) x IOH} + (VOl x IOL)
2: Voltage spikes below VSS at the MCLR/VPP pin, inducing currents greater than 80 mA, may cause latch-up.Thus, a series resistor of 50-100 should be used when applying a "low" level to the MCLR/VPP pin ratherthan pulling this pin directly to VSS.
† NOTICE: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to thedevice. This is a stress rating only and functional operation of the device at those or any other conditions above those
indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions forextended periods may affect device reliability.
DescriptionThis document contains device specific information for he following devices:
• PIC18F6585 • PIC18F8585
• PIC18F6680 • PIC18F8680
PIC18F8680 devices are available in 64-pin TQFP and68-pin PLCC packages. PIC18F8X8X devices areavailable in the 80-pin TQFP package. They aredifferentiated from each other in four ways:
1. Flash program memory (48 Kbytes forPIC18FX585 devices, 64 Kbytes forPIC18FX680)
2. A/D channels (12 for PIC18F6X8X devices,16 for PIC18F8X8X)
3. I/O ports (7 on PIC18F6X8X devices, 9 onPIC18F8X8X)
4. External program memory interface (presentonly on PIC18F8X8X devices)
All other features for devices in the PIC18F8680 family are identical.These are summarized in Table 1-1.
Block diagrams of the PIC18F6X8X and PIC18F8680 devices are provided in Figure 1-1 and Figure 1-2,respectively. The pinouts for these device families arelisted in Table 1-2.
