    CY7C68013A and I2C slave device with 1.8v interface

    bernardo.cavero

       Hi,

         

      I would like to connect an I2C slave device to the CY7C68013A. The problem is that the slave device pins use 1.8v. The slave device pins are the following:

         

      - SDA: 1.8v

         

      - SCL: 1.8v

         

      - INT: 1.8v (interrup control pin)

         

      - RESET: 1.8v

         

      I have been thinking to use a bidirectional voltage level translator ic for the 4 pins (i.e.: NXP NVT2004).

         

      Is there are any alternative way to do it?

         

      Is there any known problem using a bidirectional voltage level translator for this task?
