5. Device Operation
The GT24C64 serial interface supports communications
using industrial standard 2-wire bus protocol, such as I2C.
5.1 2-WIRE Bus
The two-wire bus is defined as Serial Data (SDA), and
Serial Clock (SCL). The protocol defines any device that
sends data onto the SDA bus as a transmitter, and the
receiving devices as receivers. The bus is controlled by
Master device that generates the SCL, controls the bus
access, and generates the Start and Stop conditions. The
GT24C64 is the Slave device.
5.2 The Bus Protocol
Data transfer may be initiated only when the bus is not busy.
During a data transfer, the SDA line must remain stable
whenever the SCL line is high. Any changes in the SDA line
while the SCL line is high will be interpreted as a Start or
Stop condition.
The state of the SDA line represents valid data after a Start
condition. The SDA line must be stable for the duration of
the High period of the clock signal. The data on the SDA line
may be changed during the Low period of the clock signal.
There is one clock pulse per bit of data. Each data transfer
is initiated with a Start condition and terminated by a Stop
condition.
5.3 Start Condition
The Start condition precedes all commands to the device
and is defined as a High to Low transition of SDA when SCL
is High. The EEPROM monitors the SDA and SCL lines and
will not respond until the Start condition is met.
5.4 Stop Condition
The Stop condition is defined as a Low to High transition of
SDA when SCL is High. All operations must end with a Stop
condition.
5.5 Acknowledge
After a successful data transfer, each receiving device is
required to generate an ACK. The Acknowledging device
pulls down the SDA line.
5.6 Reset
The GT24C64 contains a reset function in case the 2-wire
bus transmission on is accidentally interrupted (e.g. a power

loss), or needs to be terminated mid-stream. The reset is
initiated when the Master device creates a Start condition.
To do this, it may be necessary for the Master device to
monitor the SDA line while cycling the SCL up to nine times.
(For each clock signal transition to High, the Master checks
for a High level on SDA.)
5.7 Standby Mode
While in standby mode, the power consumption is minimal.
The GT24C64 enters into standby mode during one of the
following conditions: a) After Power-up, while no Op-code is
sent; b) After the completion of an operation and followed
by the Stop signal, provided that the previous operation is
not Write related; or c) After the completion of any internal
write operations.
5.8 Device Addressing
The Master begins a transmission on by sending a Start
condition, then sends the address of the particular Slave
devices to be communicated. The Slave device address is 8
bits format as shown in Figure. 5-5.
The four most significant bits of the Slave address are fixed
(1010) for GT24C64.
The next three bits, A0, A1 and A2, of the Slave address are
specifically related to EEPROM. Up to eight GT24C64 units
can be connected to the 2-wire bus.
The last bit of the Slave address specifies whether a Read
or Write operation is to be performed. When this bit is set to
1, Read operation is selected. While it is set to 0, Write
operation is selected.
After the Master transmits the Start condition and Slave
address byte appropriately, the associated 2-wire Slave
device, GT24C64, will respond with ACK on the SDA line.
Then GT24C64 will pull down the SDA on the ninth clock
cycle, signaling that it received the eight bits of data.
The GT24C64 then prepares for a Read or Write operation
by monitoring the bus.
