Parameters are valid over operating temperature range unless otherwise specified. 2. Load capacitance for port 0, ALE, and PSEN = 100 pF, load capacitance for all other outputs = 80 pF. 3. tCLCL = 1/fOSC = one oscillator clock period. tCLCL = 83.3ns at fOSC = 12 MHz. tCLCL = 62.5ns at fOSC = 16 MHz. 4. These values are characterized but not 100% production tested. |
