LE24L043CB
CMOS IC
Two Wire Serial Interface
EEPROM (4k EEPROM)
Overview
The LE24L043CB is a 2-wire serial interface EEPROM. It realizes high speed and a high level reliability by
incorporating SANYO’s high performance CMOS EEPROM technology. This device is compatible with I2C memory
protocol, therefore it is best suited for application that requires small-scale re-writable nonvolatile parameter memory.
Functions
• Capacity: 4k bits (512 × 8 bits)
• Single supply voltage: 1.7V to 3.6V
• Interface: Two wire serial interface (I2C Bus*)
• Operating clock frequency: 400 kHz
• Low power consumption
: Standby: 2μA (max)
: Active (Read): 0.5mA (max)
• Automatic page write mode: 16 Bytes
• Read mode: Sequential read and random read
• Erase/Write cycles: 105 cycles
• Data Retention: 20 years
• High reliability: Adopts SANYO’s proprietary symmetric memory array configuration (USP6947325)
Noise filters connected to SCL and SDA pins
Incorporates a feature to prohibit write operations under low voltage conditions.
• Package: LE24L043CB: WLP5 (1.05 х 0.78)

"standard application", intended for the use as general electronics equipment (home appliances, AV equipment,
communication device, office equipment, industrial equipment etc.). The products mentioned herein shall not be
intended for use for any "special application" (medical equipment whose purpose is to sustain life, aerospace
instrument, nuclear control device, burning appliances, transportation machine, traffic signal system, safety
equipment etc.) that shall require extremely high level of reliability and can directly threaten human lives in case
of failure or malfunction of the product or may cause harm to human bodies, nor shall they grant any guarantee
thereof. If you should intend to use our products for applications outside the standard applications of our
customer who is considering such use and/or outside the scope of our intended standard applications, please
consult with us prior to the intended use. If there is no consultation or inquiry before the intended use, our
customer shall be solely responsible for the use.

LE24L043CB
Functional Description
1 Start condition
When the SCL line is at the high level, the start condition is established by changing the SDA line from high to low.
The operation of the EEPROM as a slave starts in the start condition.
2 Stop condition
When the SCL line is at the high level, the stop condition is established by changing the SDA line from low to high.
When the device is set up for the read sequence, the read operation is suspended when the stop condition is received,
and the device is set to standby mode. When it is set up for the write sequence, the capture of the write data is ended
when the stop condition is received, and the EEPROM internal write operation is started.

3 Data transfer
Data is transferred by changing the SDA line while the SCL line is low. When the SDA line is changed while the SCL
line is high, the resulting condition will be recognized as the start or stop condition.

B. If it is not possible to satisfy the instruction 2 in Note above
After the power has stabilized, software reset must be executed.
C. If it is not possible to satisfy the instructions both 1 and 2 in Note above
After the power has stabilized, the steps in A must be executed, then software reset must be executed.
5) Noise filter for the SCL and SDA pins
This product contains a filter circuit for eliminating noise at the SCL and SDA pins. Pulses of 100ns or less are not
recognized because of this function.
6) Function to inhibit writing when supply voltage is low
This product contains a supply voltage monitoring circuit that inhibits inadvertent writing below the guaranteed
operating supply voltage range. The data is protected by ensuring that write operations are not started at voltages (typ.)
of 1.3V and below.
7) Slave address settings
This product does not come with any slave address pins, but the information of the S1 and S2 slave addresses is held
internally. S1 = 0 and S2 = 0 were set for the slave addresses before shipment. During device addressing, these
slave address codes must be executed following the device code.
