Ambient temperature under bias.......................................................-40°C to +125°C
Storage temperature ........................................................................... -65°C to +150°
Voltage on any pin with respect to VSS (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 VI > 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 VSS at the RG5/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 RG5/MCLR/ V_PP pin, rather than pulling this pin directly to V_SS.

† NOTICE: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. 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 for
extended periods may affect device reliability.

Description

PIC18F8722 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 PIC18F8722  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 PIC18F8720.
