AC Electrical Characteristics
AC Chip Level Specifications
Table 22 lists guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V and -40°C
≤ T_A ≤ 85°C, or 3.0V to 3.6V and -40°C ≤ T_A ≤ 85°C, respectively. Typical parameters apply to 5V and 3.3V at 25°C. These are for
design guidance only.

Notes
11. 4.75V < Vdd < 5.25V.
12. Accuracy derived from Internal Main Oscillator with appropriate trim for Vdd range.
13. 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.
14. See the individual user module data sheets for information on maximum frequencies for user modules.
