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:
• VDD 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: PIC16C54C-40/P).
4: For operation between DC and 20 MHz, see Section 17.1.
