Title: [TEI0006-04-API23A]: VCCIO Bank 2K/2J LVCMOS 3.3V compatibility
Post by: guirenaud on September 16, 2025, 10:46:39 AM
Hello

Regarding VCCIO 2K/2L 3V supplies, can it be supplied with standard 3.3V power module like the one used in the TEIB0006 5V in to 3.3V out (MPM3860GQW-Z)?
Can i use 3.3V supply for VCCIO 2K/2L ?

Sincerely

Guillaume

Hello

I need probably to rephrase my initial post, to give you a bit of context.

I'm using the SOM TEI0006-04-API23A and developping a custom motherboard around it.

It is mentioned in the datasheet (https://wiki.trenz-electronic.de/display/PD/TEI0006+TRM#TEI0006TRM-PowerandPower-OnSequence (https://wiki.trenz-electronic.de/display/PD/TEI0006+TRM#TEI0006TRM-PowerandPower-OnSequence)) that we need to supply 5V for the SOM but with which minimum current ?

Regarding the bank voltages Bank 2K and 2J it is mentioned (rev. v.89 of the online Tec. Ref. Manual)that we can supply VCCIO2J and VCCIO2K in the range from 1.2V to 1.8V. I'm interested to supply it with 3V is it possible ? In theory it should be right?

Sincerely

Guillaume
