ADM1063  
•
To erase a page of EEPROM memory. EEPROM memory  
In the ADM1063, the write byte/word protocol is used for  
three purposes:  
can be written to only if it is unprogrammed. Before writing  
to one or more EEPROM memory locations that are already  
programmed, the page(s) containing those locations must  
first be erased. EEPROM memory is erased by writing a  
command byte.  
•
To write a single byte of data to RAM. In this case, the  
command byte is the RAM addresses from 0x00 to 0xDF  
and the only data byte is the actual data, as shown in  
Figure 44.  
The master sends a command code that tells the slave device  
to erase the page. The ADM1063 command code for a page  
erasure is 0xFE (1111 1110). Note that, for a page erasure  
to take place, the page address must be given in the previous  
write word transaction (see the Write Byte/Word section).  
Also, Bit 2 in the UPDCFG register (Address 0x90) must  
be set to 1.

•
To set up a 2-byte EEPROM address for a subsequent  
read, write, block read, block write, or page erase. In this  
case, the command byte is the high byte of the EEPROM  
addresses from 0xF8 to 0xFB. The only data byte is the low  
byte of the EEPROM address, as shown in Figure 45.

As soon as the ADM1063 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 ADM1063 is  
accessed before erasure is complete, it responds with a  
no acknowledge (NACK).

Figure 45. Setting an EEPROM Address  
Note that for page erasure, because a page consists of  
32 bytes, only the 3 MSBs of the address low byte are  
important. The lower five bits of the EEPROM address  
low byte specify the addresses within a page and are  
ignored during an erase operation.  
Write Byte/Word  
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:  
•
To write a single byte of data to EEPROM. In this case, the  
command byte is the high byte of the EEPROM addresses  
from 0xF8 to 0xFB. The first data byte is the low byte of the  
EEPROM address, and the second data byte is the actual  
data, as shown in Figure 46.  
1. The master device asserts a start condition on SDA.  
2. The master sends the 7-bit slave address followed by the  
write bit (low).

6. The master sends a data byte.  
In a block write operation, the master device writes a block of  
data to a slave device. The start address for a block write must  
have been set previously. In the ADM1063, a send byte opera-  
tion sets a RAM address, and a write byte/word operation sets  
an EEPROM address, as follows:  
7. The slave asserts ACK on SDA.  
8. The master sends a data byte or asserts a stop condition.  
9. The slave asserts ACK on SDA.  
1. The master device asserts a start condition on SDA.  
10. The master asserts a stop condition on SDA to end  
the transaction.  
2. The master sends the 7-bit slave address followed by  
the write bit (low).  
3. The addressed slave device asserts ACK on SDA.
