 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?

If the I2C slave cannot handle 3.3 V signals, then using a level translator is a solution.
