hello Longchang,

I2C Slave address is different for TMP432A and TMP432B as specified in page 2 of data sheet. This is to distinguish multiple TMP432 devices connected to the same serial bus, since TMP432 does NOT have additional ADDR pins.

Regards,

Abhi

Hi Longchang,

As Abhi mentioned the difference is the two-wire address. The address of the TMP432A is 4Ch (1001100b). The address of the TMP432B is 4Dh (1001101b). You can find a little bit of explaition on this on Page 25 of the datasheet as well.

Best Regards,
Mayrim
