2. General Description
The LT24C08 is an industrial standard electrically erasable programmable read only
memory (EEPROM) device that utilizes the industrial standard 2-wire interface for LT24C08
contains a memory array of 8K bits (1,024x8), which is organized in 16-byte per page.
The EEPROM operates in a wide voltage range from 1.7V 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 SOIC/SOP.
LT24C08 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
LT24C08. 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 LT24C08 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 CC ) has
reached an acceptable stable level above the reset threshold voltage. Once VCC passes
the power on reset threshold, the device is reset and enters into the 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 CC drops below the
power on reset 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 V CC reaches its
