Hi!

Do you have a datasheet for the CY8C4045FNI-DS400T ?  This 20-WLCSP part is not mention in the datasheets.

In PSoC Creator it also has fixed VCONN1, VCONN2, RD1, CC1 and RD1 pins.  See attached pic.

What are those pins for?

I have a feeling it may be an undocumented PD part similar to the EZ-PD / CCG2.

Both Mouser and Digi-Key stock CY8C4045FNI-DS400T.

Thanks!

Many thanks Alen.

It looks like PSoC Creator pin selector needs updating to reflect the datasheet.

I am using the part as a boot & config tool for some 1.8v level i2c parts.  I note the pins P0.0 and P0.1 are overvoltage-tolerant.  Does this indicate the part can be used as a level shifter of sorts? P0.0 / P0.1 at external 3v3 level and P1.3/P1.0 at local 1v8 VDDIO level?

Hi @djsftree ,

>> Does this indicate the part can be used as a level shifter of sorts? P0.0 / P0.1 at external 3v3 level and P1.3/P1.0 at local 1v8 VDDIO level?

By this do you mean to connect the P0.0/P0.1 pins to P1.3/P1.0 in the PSoC Creator schematic as hardware connections so that you can achieve level shifting using this device?

Warm Regards
