SUMMARY DESCRIPTION
These I
2
C-compatible electrically erasable pro-
grammable memory (EEPROM) devices are orga-
nized as 64K x 8 bits.
Figure 2. Logic Diagram
Table 2. Signal Names
I
2
C uses a two-wire serial interface, comprising a
bi-directional data line and a clock line. The devic-
es carry a built-in 4-bit Device Type Identifier code
(1010) in accordance with the I
2
C bus definition.
The device behaves as a slave in the I
2
C protocol,
with all memory operations synchronized by the
serial clock. Read and Write operations are initiat-
ed by a Start condition, generated by the bus mas-
ter. The Start condition is followed by a Device
Select Code and Read/Write bit (RW) (as de-
scribed in
Table 3.
), terminated by an acknowl-
edge bit.
When writing data to the memory, the device in-
serts an acknowledge bit during the 9
th
bit time,
following the bus master’s 8-bit transmission.
When data is read by the bus master, the bus
master acknowledges the receipt of the data byte
in the same way. Data transfers are terminated by
a Stop condition after an Ack for Write, and after a
NoAck for Read.
Power On Reset
In order to prevent data corruption and inadvertent
Write operations during Power-up, a Power On
Reset (POR) circuit is included. At Power-up, the
device will not respond to any command until V
CC
has reached the Power On Reset threshold volt-
age (this threshold is lower than the V
CC
min oper-
ating voltage defined in Tables
8
and
9
). In the
same way, as soon as V
CC
drops from the normal
operating voltage, below the Power On Reset
threshold voltage, the device stops to respond to
any command.
Prior to selecting and issuing commands to the
memory, a valid and stable V
CC
voltage must be
applied. This voltage must remain stable and valid
until the end of the transmission of the command
and, for a Write instruction, until the completion of
the internal write cycle (t
W
).
