Notes

13.4.75V < Vdd < 5.25V.

14.Accuracy derived from Internal Main Oscillator with appropriate trim for Vdd range.

15.3.0V < Vdd < 3.6V. See Application Note AN2012 “Adjusting PSoC Microcontroller Trims for Dual Voltage-Range Operation” for information on trimming for operation at 3.3V.

16.See the individual user module data sheets for information on maximum frequencies for user modules.
