Ambient temperature under bias.......................................................................................................-40°C to +125°C
Storage temperature ....................................................................................................................... -65°C to +150°C
Voltage on any pin with respect to V_SS (except V_DD and MCLR) ................................................... -0.3V to (V_DD + 0.3V)
Voltage on V_DD with respect to V_SS ........................................................................................................ -0.3V to +7.5V
Voltage onMCLR with respect to V_SS (Note 2) ........................................................................................ 0V to +13.25V
Total power dissipation (Note 1) .............................................................................................................................1.0W
Maximum current out of V_SS pin ...........................................................................................................................300 mA
Maximum current into V_DD pin .............................................................................................................................250 mA
Input clamp current, I_IK (V_I < 0 or V_I > V_DD)...................................................................................................... ±20 mA
Output clamp current, I_OK (V_O < 0 or V_O > V_DD) ................................................................................................ ±20 mA
Maximum output current sunk by any I/O pin.........................................................................................................25 mA
Maximum output current sourced by any I/O pin ...................................................................................................25 mA
Maximum current sunk by all ports ......................................................................................................................200 mA
Maximum current sourced by all ports ..................................................................................................................200 mA

Note 1: Power dissipation is calculated as follows:Pdis = V_DD x {I_DD I_OH} + {(V_DD V_OH) x I_OH} + (V_OL x I_OL)
2: Voltage spikes below V_SS at the MCLR/V_PP/RG5 pin, inducing currents greater than 80 mA, may causelatch-up. Thus, a series resistor of 50-100 should be used when applying a "low" level to the MCLR/V_PP/RG5 pin, rather than pulling this pin directly to V_SS.

† 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 thoseindicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions forextended periods may affect device reliability.

Description

PIC18F8622 is Ideal for large low power (nanoWatt) and connectivity applications that benefit from the availability of four serial ports: double synchronous serial ports (I2C? and SPI?) and double asynchronous (LIN capable) serial ports. Large amounts of RAM memory for buffering and FLASH program memory make it ideal for instrumentation panels, TCP/IP enabled embedded applications as well as metering and industrial control and monitoring applications. While operating up to 40 MHz, it is also backward software and hardware compatible with the PIC18F8620/8621.
