Hi，
1. Does TMP1826 have an EEPROM erase command? How to erase?
2. EEPROM programming can only be written according to blocks. After writing one block, must I lock it before writing another? What happens if I don't lock it?
3. Is EEPROM read by page, Can I read by block?
4. Do you have any related demo programs?
1. You must overwrite every block with WRITE and COPY to erase the entire EEPROM.
2. You don't need to lock it immediately after WRITE-SCRATCHPAD, but you do need to COPY-SCRATCHPAD immediately to commit it to EEPROM.
3. All read, write, copy commands operate on one block at a time. Each block contains 8 bytes (64 bits.) Lock, known as User Memory Protection, can only be enabled for pages, which encompass 4 blocks.
4. There is source code in ASCStudio https://dev.ti.com/sysconfig/index.html?product=ascstudio&module=/ti/sensors/tempsensor/TMP1826 as well as on the product landing page. https://www.ti.com/product/TMP1826#software-development
