Unlock Chip Microprocessor ATXMEGA192A1 Eeprom

We can Unlock Chip Microprocessor ATXMEGA192A1 Eeprom, please view the Chip Microprocessor ATXMEGA192A1 features for your reference:

The User Signature Row is a seperate memory section that is fully accessible (read and write) from application software and external programming. The User Signature Row is one flash page in size, and is meant for static user parameter storage, such as calibration data, custom serial numbers, random number seeds etc. This section is not erased by Chip Erase, and requires a dedicated erase command. This ensures parameter storage during multiple program/erase session and On-Chip Debug sessions after the eeprom of chip being unlocked.

The Flash Program Memory and EEPROM data memory is organized in pages. The pages are word accessible for the Flash and byte accessible for the EEPROM.

Table 7-2 on page 14 shows the Flash Program Memory organization. Flash write and erase operations are performed on one page at the time, while reading the Flash is done one byte at the time. For Flash access the Z-pointer (Z[m:n]) is used for addressing.

The most significant bits in the address (FPAGE) gives the page number and the least significant address bits (FWORD) gives the word in the page. Table 7-3 on page 14 shows EEPROM memory organization for the XMEGA A1 devices.

EEPROM write and erase operations can be performed one page or one byte at the time, while reading the EEPROM is done one byte at the time. For EEPROM access the NVM Address Register (ADDR[m:n]) is used for addressing. The most significant bits in the address (E2PAGE) gives the page number and the least significant address bits (E2BYTE) gives the byte in the page before unlocking eeprom of microprocessor.
