ADM1066
The master sends a command code telling the slave device
to erase the page. The ADM1066 command code for a page
erasure is 0xFE (1111 1110). Note that for a page erasure to

Figure 42. Setting an EEPROM Address
Because a page consists of 32 bytes, only the three MSBs of
the address low byte are important for page erasure. The
lower five bits of the EEPROM address low byte specify the
addresses within a page and are ignored during an erase
operation.

Figure 40. EEPROM Page Erasure
As soon as the ADM1066 receives the command byte,
page erasure begins. The master device can send a stop
command as soon as it sends the command byte. Page
erasure takes approximately 20 ms. If the ADM1066 is
accessed before erasure is complete, it responds with a
no acknowledge (NACK).
Write Byte/Word
?
To write a single byte of data to the EEPROM. In this case,
the command byte is the high byte of EEPROM Address 0xF8
to EEPROM Address 0xFB. The first data byte is the low
byte of the EEPROM address, and the second data byte is

In a write byte/word operation, the master device sends a
command byte and one or two data bytes to the slave device, as
follows:

have been set previously. In the ADM1066, a send byte opera-
