Preliminary DS30453B-page 109 PIC16C54A PIC16C5X 14.5 DC Characteristics: PIC16C54A-04, 10, 20, PIC16LC54A-04, PIC16LV54A-02 (Commercial) PIC16C54A-04I, 10I, 20I, PIC16LC54A-04I, PIC16LV54A-02I (Industrial) PIC16C54A-04E, 10E, 20E (Extended) DC Characteristics All Pins Except Power Supply Pins Standard Operating Conditions (unless otherwise specified) Operating Temperature 0 °C ≤ TA ≤ +70°C (commercial) –40 °C ≤ TA ≤ +85°C (industrial) –20 °C ≤ TA ≤ +85°C (industrial - PIC16LV54A-02I) –40 °C ≤ TA ≤ +125°C (extended) Operating Voltage VDD range is described in Section 14.1, Section 14.2 and Section 14.3.

Note 1: Data in the Typical (“Typ”) column is based on characterization results at 25 °C.This data is for design guidance only and is not tested. 2: The leakage current on the MCLR/VPP pin is strongly dependent on the applied voltage level. The specified levels represent normal operating conditions. Higher leakage current may be measured at different input voltage. 3: Negative current is defined as coming out of the pin. 4: For the RC option, the OSC1/CLKIN pin is a Schmitt Trigger input. It is not recommended that the PIC16C5X be driven with external clock in RC mode. 5: The user may use the better of the two specifications. |
