address pin allows for the DS4510 to respond to one of
two slave addresses (1010000X, or 1010001X). If the
R/ W bit is zero, the master writes data to the slave. If
the R/ W is one, the master reads data from the slave.
Memory Address: During an I 2 C write operation, the
master must transmit a memory address to identify the
memory location where the slave is to store the data.
The memory address is always the second byte trans-
mitted during a write operation following the slave
address byte (R/ W = 0).

Writing a Single Byte to a Slave: The master must
generate a start condition, write the slave address
(R/ W = 0), write the memory address, write the byte of
data and generate a stop condition. Remember the
master must read the slave’s acknowledgement during
all byte write operations.
Writing a Multiple Bytes to a Slave: To write multiple
bytes to a slave the master generates a start condition,
writes the slave address (R/ W = 0), writes the memory
address, writes up to 8 data bytes, and generates a
stop condition.
The DS4510 can write 1 to 8 bytes (one page or row)
with a single write transaction. This is internally con-
trolled by an address counter that allows data to be
written to consecutive addresses without transmitting a
memory address before each data byte is sent. The
address counter limits the write to one 8-byte page
(one row of the memory table , see Figure 3). Attempts
to write to additional pages of memory without sending
a stop condition between pages results in the address
counter wrapping around to the beginning of the pre-
sent row.
Example: A 3-byte write starts at address 06h and
writes three data bytes (11h, 22h, and 33h) to three
“consecutive” addresses. The result would be address-

es 06h and 07h would contain 11h and 22h, respective-
ly, and the third data byte, 33h, would be written to
address 00h.

To prevent address wrapping from occurring, the mas-
ter must send a stop condition at the end of the page,
then wait for the bus-free or EEPROM-write time to
