18.0 DEVICE CHARACTERIZATION - PIC16LC54A

The graphs and tables provided following this note are a statistical summary based on a limited number of samples and

are provided for informational purposes only. The performance characteristics listed herein are not tested or guaran-

teed. In some graphs or tables, the data presented may be outside the specified operating range (e.g., outside specified

power supply range) and therefore outside the warranted range.

“Typical” represents the mean of the distribution at 25°C. “Maximum” or “minimum” represents (mean + 3) or (mean

– 3) respectively, where  is a standard deviation, over the whole temperature range.

The frequencies are measured on DIP packages.

The percentage variation indicated here is part-to-part variation due to normal process distribution. The variation

indicated is ±3 standard deviation from average value for VDD = 5V.
