More than one TDA8029 in I2C bus

[mariocruz]

Hi!

 I want to desing a dual contact smart card reader managed by I2c bus. I ´d like to use two TDA8029 ic, but it only has one fixed i2c address. How can I set a different I2c address to one of them for using more than one in parallel?

Thanks a lot!

Hello,

It only has one fixed I2C address (0x50). Fortunately, it can also be interfaced through RS232. The host interface is chosen by connecting P17 to VDD for RS232 or to GND for I2C.

Please refer to chapter 2.2 Host Controller Interface of the following document:

I hope this helps.

Regards,

Ivan.
