Preliminary DS41206A-page 99 PIC16F716 TABLE 12-2: EXTERNAL CLOCK TIMING REQUIREMENTS Param No. Sym Characteristic Min Typ† Max Units Conditions 1A FOSC Ext.

These parameters are for design guidance only and are not tested. Note 1: Instruction cycle period (TCY) equals four times the input oscillator time base period. All specified values are based on characterization data for that particular oscillator type under standard operating conditions with the device executing code. Exceeding these specified limits may result in an unstable oscillator operation and/or higher than expected current consumption. All devices are tested to operate at "min." values with an external clock applied to the OSC1/CLKIN pin. When an external clock input is used, the "Max." cycle time limit is "DC" (no clock) for all devices. |
