# W7500P I2C Errata

## Question

Asked by tge on 2023-02-01 in MCU & Boards.

Hi, The W7500P Errata states that the I2C peripheral does not work but there is a bit bang alternative for 100KHz. Is there still a problem with the I2C HW or has this been fixed in the latest silicon?

Sorry, but I2C hasn’t improved yet.
