Preliminary Technical Data

ADM1068

•

To erase a page of EEPROM memory. EEPROM memory

can be written to only if it is unprogrammed. Before

writing to one or more EEPROM memory locations that

are already programmed, the page or pages containing

those locations must first be erased. EEPROM memory is

erased by writing a command byte.

In the ADM1068, the write byte/word protocol is used for three

purposes:

•

To write a single byte of data to RAM. In this case, the

command byte is the RAM address from 0x00 to 0xDF and

the only data byte is the actual data, as shown in Figure 30.

The master sends a command code that tells the slave

device to erase the page. The ADM1068 command code for

a page erasure is 0xFE (1111 1110). Note that, for a page

erasure to take place, the page address has to 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 address

from 0xF8 to 0xFB. The only data byte is the low byte of

the EEPROM address, as shown in Figure 31.

As soon as the ADM1068 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 ADM1068 is

accessed before erasure is complete, it responds with a no

acknowledge (NACK).

Figure 31. Setting an EEPROM Address

Note, for page erasure, that because a page consists of

32 bytes, only the three 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 address

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 32.

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).

3. The addressed slave device asserts ACK on SDA.

4. The master sends a command code.

5. The slave asserts ACK on SDA.

Block Write

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 ADM1068, a send byte opera-

tion sets a RAM address, and a write byte/word operation sets

an EEPROM address, as follows:

6. The master sends a data byte.

7. The slave asserts ACK on SDA.

8. The master sends a data byte (or asserts a stop condition at

this point).

1. The master device asserts a start condition on SDA.

9. The slave asserts ACK on SDA.

2. The master sends the 7-bit slave address followed by

the write bit (low).

10. The master asserts a stop condition on SDA to end the

transaction.

3. The addressed slave device asserts ACK on SDA.

4. The master sends a command code that tells the slave

device to expect a block write. The ADM1068 command

code for a block write is 0xFC (1111 1100).
