Pinout of CY8C4146LQE-S433 vs. CY8C4146LQI-S433?

[MaPi_4112356]

Greetings,

I kind of thought that the pinouts of CY8C4146LQE-S433 and CY8C4146LQI-S433 would be identical, but it seems that they are not. Is this really the case?

From Automotive PSoC4:PSoC 4100S Family Datasheet (document: 002-15106 Rev. *F):

And from PSoC4: PSoC 4100S Datasheet (Document 002-00122 Rev. *L):

Hi Matti,

Yes, what you are seeing in both the datasheets is actually correct. Both devices do not have identical pin-outs .There is difference in power supply pins for both the  devices (i.e. CY8C4146LQE-S433 and CY8C4146LQI-S433) which you can observe in datasheets . Also, it's should be noted that CY8C4146LQI -S433 is Industrial grade (device name ending with 'I') where as CY8C4146LQE-S433 is Automotive Grade  (device name ending 'E','A' and 'S').

Hi Ashish,

thank you for the quick response!

Ok - got it! I was just trying to be smart and do the prototype with the industrial grade device and move to automotive grade later on. Obviously that plan backfired.
