DC Analog PSoC Block Specifications

Tab le 14 lists guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75 V to 5.25 V and –40

°C  T

 85 °C, or 3.0 V to 3.6 V and –40 °C  T

 85 °C, respectively. Typical parameters apply to 5 V and 3.3 V at 25 °C and are

for design guidance only.

Notes

7. Errata: When V

of the device is pulled below ground just before power on, the first read from each 8K Flash page may be corrupted. This issue does not affect Flash

page 0 because it is the selected page upon reset. More details in “Errata” on page 46.

8. Always greater than 50 mV above PPOR (PORLEV = 00) for falling supply.

9. Always greater than 50 mV above PPOR (PORLEV = 10) for falling supply.
