Hello,

From your schematic, it isnt clear if your EEPROM address is 0x51 or 0x50 based on the A0 pin. Please clarify the same?

Since your EEPROM size is of 32 x 8 bytes, it requires one-byte addressing and hence is considered to be a small EEPROM. Kindly connect the address lines set to 0x50 and the try the transfer on the Console. You could also refer to the KBA for more details.

Best Regards,

Sananya

Hi,

If all the three address lines A2,A1,A0 are pulled so ground, the 7-bit address will be set to 0x50 and the write should work when you choose Small EEPROM option on CyConsole to download firmware.

Best Regards,
