Frequency (MHz)

(Volts)

Note 1: The shaded region indicates the permissible combinations of voltage and frequency.

2: The maximum rated speed of the part limits the permissible combinations of voltage and frequency.

Please reference the Product Identification System section for the maximum rated speed of the parts.

3: Operation between 20 to 40 MHz requires the following:

• V

DD between 4.5V. and 5.5V

• OSC1 externally driven

• OSC2 not connected

• HS mode

• Commercial temperatures

Devices qualified for 40 MHz operation have -40 designation (ex: PIC16C620A-40/P).
