AN-1104 I2C Level Shifter
I2C level-shifters are very useful when two I2C-enabled devices need to communicate to each other across different voltage domains (VDD). This problem occurs often when new designs with lower VDD are added to existing designs with higher VDD. Silego’s dual-rail programmable logic IC can be programmed to function as an I2C level-shifter. This application note explains how to build an I2C level-shifter that meets I2C Fast Mode specs, which has a max data rate of 400kbps.
