AC Electrical Characteristics

AC Chip-Level Specifications

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

a.4.75V < Vdd < 5.25V.

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

c.3.0V < Vdd < 3.6V. See Application Note AN2012 “Adjusting PSoC Microcontroller Trims for Dual Voltage-Range Operation” for information on trimming for opera- tion at 3.3V.

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

e.3.0V < 5.25V.

f.The crystal oscillator frequency is within 100 ppm of its final value by the end of the Tosacc period. Correct operation assumes a properly loaded 1 uW maximum drive level 32.768 kHz crystal. 3.0V ≤ Vdd ≤ 5.5V, -40 oC ≤ TA ≤ 85 oC.
