4K/8K 2-Wire (512x8/1,024x8)
3V~5.5V CMOS Serial EEPROM
PRELIMINARY
A
read from the last byte of the last memory page
to the first byte of the first page. The addresses
roll over during write from the last byte of the
current page to the first byte of the same page.
Once the device address with the read/write
select bit set to one is clocked in and
acknowledged by the EEPROM, the current
address data word is serially clocked out. The
microcontroller should respond with a “no ACK”
signal (high) followed by a stop condition (refer
to Current read timing).
z Random read
A random read requires a dummy byte write
sequence to load in the data word address
which is then clocked in and acknowledged by
the EEPROM. The microcontroller must then
generate another start condition. The
microcontroller now initiates a current address
read by sending a device address with the
read/write select bit high. The EEPROM
Current read tim ing
acknowledges the device address and serially
clocks out the data word. The microcontroller
should respond with a “no ACK” signal (high)
followed by a stop condition (refer to Random
read timing).
z Sequential read
Sequential reads are initiated by either a
current address read or a random address read.
After the microcontroller receives a data word,
it responds with an acknowledgment. As long
as the EEPROM receives an acknowledgment,
it will continue to increment the data word
address and serially clock out sequential data
words. When the memory address limit is
reached, the data word address will roll over
and the sequential read continues. The
sequential read operation is terminated when
the microcontroller responds with a ”no ACK”
signal (high) followed by a stop condition.
