A24C08
EEPROM
8K BITS (1024 X 8) TWO-WIRE SERIAL
DESCRIPTION
A24C08 provides 8192 bits of serial electrically
erasable and programmable read-only memory
(EEPROM) organized as 1024 words of 8 bits
each.
The device is optimized for use in many
industrial and commercial applications where
low-power and low-voltage operations are
essential.
The A24C08 is accessed via a two-wire serial
interface.
TheA24C08 is available in SOP8, TSSOP8and
DFN8 packages.

3. DEVICE ADDRESSING
The 8K EEPROM devices all require an 8-bit device address word following a start condition to enable the
chip for a read or write operation (see to Figure 4 on page 12).
The device address word consists of a mandatory "1", "0" sequence for the first four most significant bits
as shown. This is common to all the Serial EEPROM devices.
The 8K EEPROM only uses the A2 device address bit with the next 2 bits being for memory page
addressing. The A2 bit must compare to its corresponding hard-wired input pin. The A1 and A0 pins are
no connect.
The eighth bit of the device address is the read/write operation select bit. A read operation is initiated if
this bit is high and a write operation is initiated if this bit is low.
