AC Electrical Characteristics

AC Chip-Level Specifications

The following tables list the guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75V to 5.25V and -40°C ≤ TA ≤ 85°C, 3.0V to 3.6V and -40°C ≤ TA ≤ 85°C, or 2.4V to 3.0V and -40°C ≤ TA ≤ 85°C, respectively. Typical parameters apply to 5V, 3.3V, or 2.7V at 25°C and are for design guidance only.

Notes

12.4.75V < Vdd < 5.25V.

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

14.3.0V < 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.

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