Note: When using the characteristic table data, the following notes should be taken into consideration:
1. Any digital inputs are setup in a non-floating condition.
2. All measurements are taken under conditions of no load and with all peripherals in an off state.
3. There are no DC current paths.
4. All Operating Current values are measured using a continuous NOP instruction program loop.
A.C. Characteristics
For data in the following tables, note that factors such as oscillator type, operating voltage, operating
frequency and temperature etc., can all exert an influence on the measured values.
High Speed Internal Oscillator – HIRC – Frequency Accuracy
During the program writing operation the writer will trim the HIRC oscillator at a user selected
HIRC frequency and user selected voltage of either 3V or 5V.

Note: 1. The 3V/5V values for V

are provided as these are the two selectable fixed voltages at which the HIRC
frequency is trimmed by the writer.
2. The row below the 3V/5V trim voltage row is provided to show the values for the full V

voltage. It is recommended that the trim voltage is fixed at 3V for application voltage ranges from 1.8V
to 3.6V and fixed at 5V for application voltage ranges from 3.3V to 5.5V.
