Hi.

My customer use PSoC 4100S Plus (CY8C4147AZI-S455 or CY8C4127AZI-S455).

My customer use GPIO.

What does "When used below Absolute Maximum conditions but above normal operating conditions, the device may not operate to specification." in "normal operating conditions" mean in the PSoC 4100S Plus datasheet ?

PSoC 4100S Plus Datasheet (P15 Note 1) : https://www.cypress.com/file/396611/download

GPIO has a maximum current of 25mA per port and a total of 200mA for multiple ports.

What is the recommended current value per port?

Hi,

Yes. The normal conditions include the operational temperature of the chip which should be -40 to +85 degrees centigrade for non automotive standard.

Also, the voltage on the VDDD and VDDA pins of the IC should be in operational limits (1.8 -5.5 volts) in case of PSoC 4.

Thanks

Ganesh
