Application note v4.04 Connection DI2CM Core to global I2C bus This document describes how to connect an DI2CM Core into global I2C Bus, in systems operat‐ ing in I2C Standard/Fast mode as well as in I2C High Speed Mode. VDD RP RP SDA SCL RS RS sdai RS RS sda sdao open drain Input Schmidt gates are recommended especially in HighSpeed mode DI2CM scli Slave device scl sclo sclhs ASIC/FPGA chip OR tri-state buffer used as a pull-up in High Speed mode and as Open-drain Input Schmidt gates are recommended especially in High‐Speed I2C mode. They prevent incidental erro‐ neous behavior caused by slow rising edges on input SCL and SDA lines. Copyright© 1999‐2011 DCD – Digital Core Design.
