# Datasheet

## Question

Asked by mich on 2017-02-01 in MCU & Boards.

Hello,

Do you have W7100-S2E datasheet please?
I did not find them on your website.
Is it specified somewhere the voltage limits?
Does it work at 3.0V?

Best regards
Mich

Hello,

The W7100-S2E is a product that uploads the S2E firmware in the W7100A chip.
Therefore, Datasheet is the same as W7100A. Please refer to the link below.
[url][http://www.wiznet.co.kr/wp-content/uploads/wiznethome/Chip/W7100A/Document/W7100A_DS_V124E.pdf\[/url\]](http://www.wiznet.co.kr/wp-content/uploads/wiznethome/Chip/W7100A/Document/W7100A_DS_V124E.pdf%5B/url%5D)

The operating voltage is 3.3V and 3V is the minimum.
Please refer to chapter 10 of the Datasheet for Electrical Specification.

Best regards,
Kei
