ADP1043A
EEPROM
The EEPROM is partitioned into two major blocks: the factory
block and the main block. The factory block contains 128 8-bit
bytes, and the main block contains 8k 8-bit bytes.
Factory Block
The factory block is organized into 128 bytes. It is used to store
the original Analog Devices factory calibration and register
settings. The user cannot change these settings. The contents
of the factory block can be downloaded to the registers at any
time by writing 0x01 to Register 0x7B.
Main Block
The main block is available to store data. It is partitioned into
16 pages; each page contains 512 bytes. The data on each page
is sorted into bytes organized in the form of eight rows and 64
columns (see Figure 35).
PAGE 0 TO PAGE 15
Main Block, Page 0 (User Settings)
The ADP1043A user register settings are stored in Page 0 of the
main block. Every time that VDD is applied to the ADP1043A,
the register settings are automatically downloaded from Page 0
of the EEPROM to the registers. The ADP1043A has a unique
command to write new values to Page 0. This is done by writing
0x00 to Register 0x7B. Clicking the Update EEPROM button in
the Analog Devices software GUI also performs this task.
MAIN Block, Page 1 to Page 15 (Scratchpad)
Page 1 to Page 15 of the main block can be used as a scratchpad
to store other data. Register 0x7C and Register 0x7D are used to
point to the page, row, and column of the byte to be accessed.
Write Example
Write data 0xAA to Page 12, Row 3, Column 30 of the
ADP1043A at I 2 C Address 0x57.

Description
Write the password to this register twice to unlock the EEPROM or to change its password
Write a command code to this register to perform one of the following EEPROM operations:
0x00: Upload registers to Page 0 of the main block (user settings)
0x01: Download factory settings (factory block) to the registers
0x02: Page erase operation
Set XADR[6:0] of EEPROM:
XADR[6:3] selects one of 16 pages of the main block
XADR[2:0] selects one of eight rows per page
Set YADR[5:0] of EEPROM:
YADR[5:0] selects one of 64 bytes in a single row
Read or write to this register to read or program a byte in EEPROM main memory
