Pin 1 and Pin 10 Incorrectly Represented by PSoC Creator™ on 44-TQFP Package for PSoC® 4100S and PSoC 4100 Plus – KBA224113

Version: **

 

Question:

Why does PSoC Creator represent Pin 1 and Pin 10 as no connections (n/c) on the 44-TQFP package for PSoC 4100S and PSoC 4100S Plus families when the datasheet shows different connections?

 

Answer:

This is a known defect in PSoC Creator 4.2. Pin 1 and Pin 10 on the 44-TQFP package for PSoC 4100S and PSoC 4100S Plus families are incorrectly represented as no connections (n/c) in the pin editor. This defect exists in PSoC Creator 4.2 and all previous versions. The datasheet specifies the correct connections for these pins. Following are the correct connections:

 

PSoC 4100S (44-TQFP package):

Pin 1 - VSSD

Pin 10 - VSSD

 

PSoC 4100S Plus (44-TQFP package):

Pin 1 - VSSD

Pin 10 - P[6]0

Impact: The misrepresentation of the VSSD connections does not have a functional impact on the design. Pin 10 misrepresented on PSoC 4100S Plus will have a functional impact. With this defect, you will not be able to assign and configure P6[0] through the pin editor. This will the addressed in the next release of PSoC Creator.
