CY8C3246LTI-162 not going into Sleep Mode

[Rusty]

Cypress PSoC CY8C3246LTI-162 - date code (611327)

When Cypress goes into a Sleep mode for "good" boards the current draw drops to 50uA on boards with the above date code the board draws ~24mA on the "bad" units. 

Do you know any changes that may have been made on the Cypress side recently? 

These products haven't had a FW or HW ECO since 2016.  The boards were assembled wk17 of 2021.

Hello @Rusty 

Can you please let me know the failure rate? How many boards have this increased current consumption?
Can you try an A-B-A swap and see if the issue is with the chip or with the board?

Best regards, 
Hari
