Eeprom I2C "SDMC DM2016" is it compatible with FCUSB CLASSIC??

hello support team, I have a question, I tried to detect this eeprom with fcusb but I did not succeed, I connected according to the diagram in the manual but I did not get results despite entering the schematic information, maybe I am wrong, could you give me an orientation for this type of IC ... Thanks!!!​


PS. I attach a photograph of the ic on the pcb and schematics​

I2C EEPROM are not detected, you set the exact part number in the settings, then select I2C mode. Then, when properly connected, it will display the data from the device. Since this is a 1024 bit, any of the 1024 size I2C devices should be compatible.

thank you for responding, it is greatly appreciated! I select 1024bit and address A0 and A2 with the i2c connection shown in the fcusb manual, it will be fine or I am skipping something: :p

The I2C Address has a default value of 0xA0 (which is the address used by EEPROM devices). The settings allow you to set bits 0, 1, 2 to HIGH for any given device (since you can daisy chain EEPROMs together and have up to 8 on a single I2C bus). Setting A0 to checked, means address bit 1 is set, which means the selected address is is 0xA1. I think for your operation, you should not have any A0/A1/A2 bits set, or just the A2 bit set.

Also, SWI has nothing to do with I2C.
