GT24C02
2 DESCRIPTION
The GT24C02 is an industrial standard electrically erasable programmable read only memory (EEPROM)
device that utilizes the industrial standard 2-wire interface for communications. The GT24C02 contains a
memory array of 2K bits (256x8), which is organized in 16-byte per page.
The EEPROM operates in a wide voltage range from 1.8V to 5.5V, which fits most application. The
product provides low-power operations and low standby current. The device is offered in Lead-free, RoHS,
halogen free or Green package. The available package types are 8-pin PDIP, SOIC/SOP, TSSOP, MSOP
and UDFN.
The GT24C02 is compatible to the standard 2-wire bus protocol. The simple bus consists of Serial Clock
(SCL) and Serial Data (SDA) signals. Utilizing such bus protocol, a Master device, such as a
microcontroller, can usually control one or more Slave devices, alike this GT24C02. The bit stream over the
SDA line includes a series of bytes, which identifies a particular Slave device, an instruction, an address
within that Slave device, and a series of data, if appropriate. The GT24C02 also has a Write Protect
function via WP pin to cease from overwriting the data stored inside the memory array.
In order to refrain the state machine entering into a wrong state during power-up sequence or a power
toggle off-on condition, a power on reset circuit is embedded. During power-up, the device does not
respond to any instructions until the supply voltage (V
) has reached an acceptable stable level above the
CC
reset threshold voltage. Once V
passes the power on reset threshold, the device is reset and enters into the
CC
Standby mode. This would also avoid any inadvertent Write operations during power-up stage. During
power-down process, the device will enter into standby mode, once V
drops below the power on reset
CC
threshold voltage. In addition, the device will be in standby mode after receiving the Stop command,
provided that no internal write operation is in progress. Nevertheless, it is not recommended to send an
command until the Vcc reaches its operating level.
