Preliminary DS30235G-page 79 PIC16C62X 12.0 89ELECTRICAL SPECIFICATIONS Absolute Maximum Ratings † Ambient Temperature under bias .............................................................................................................. -40 ° to +125°C Storage Temperature................................................................................................................................. -65 ° to +150°C Voltage on any pin with respect to VSS (except VDD and MCLR)....................................................... -0.6V to VDD +0.6V Voltage on VDD with respect to VSS ................................................................................................................ 0 to +7.5V Voltage on MCLR with respect to VSS (Note 2)..................................................................................................0 to +14V Total power Dissipation (Note 1) ...............................................................................................................................1.0W Maximum Current out of VSS pin...........................................................................................................................300 mA Maximum Current into VDD pin .............................................................................................................................250 mA Input Clamp Current, IIK (VI <0 or VI> VDD) ......................................................................................................................±20 mA Output Clamp Current, IOK (VO <0 or VO>VDD) ...............................................................................................................±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 PORTA and PORTB ...................................................................................................200 mA Maximum Current sourced by PORTA and PORTB ..............................................................................................200 mA Note 1: Power dissipation is calculated as follows: PDIS = VDD x {IDD - ∑ IOH} + ∑ {(VDD-VOH) x IOH} + ∑(VOl x IOL) † 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. Note: Voltage spikes below VSS at the MCLR pin, inducing currents greater than 80 mA, may cause latch-up. Thus, a series resistor of 50-100 Ω should be used when applying a "low" level to the MCLR pin rather than pulling this pin directly to VSS.
