Hi team,
Our customer is now testing DS250DF230. and encountered problem as below, could you help to check on this?
during I2C communication there's NACK after DeviceAdress. Are there other I2C timing requirements that are not specified in the manual, or other possible reasons?
【Datasheet】
【Peripheral hardware test situation】：
1. Power supply VDD=2.5V, the test is normal;
2. EN_SMB is pulled up to VDD through 1K, 2.5V at the PIN pin;
3. The reset signal is normal before access, READ_EN_IN and All_DONE_N are High=3.3V during access;
4. CLK_IN and CLK_OUT, 25M is normal;
5. DeviceAdress=0x30;
6.tHD_DAT=tSU_DAT=4us;
