LE24LA162CB
CMOS IC
Two Wire Serial Interface
EEPROM (16k EEPROM)
Overview
The LE24LA162CB 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: 16k bits (2k × 8 bits)
• Single supply voltage: 1.7V to 3.6V
• Interface: Two wire serial interface (I2C Bus*)
• Operating clock frequency: 400kHz
• 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 : LE24LA162CB : WLP6J(1.06 х 1.50)

LE24LA162CB
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.
