Overview
The LE24163LBXA (hereinafter referred to as ‘this device’) is two-wire serial interface EEPROM (Electrically
Erasable and Programmable ROM). This device realizes high speed and a high level reliability by our company’s high
performance CMOS EEPROM technology. This device is compatible with I2C memory protocol, therefore it is best
suited for application that requires re-writable nonvolatile parameter memory.

Operating temperature: 40ºC to +85ºC
Interface: Two wire serial interface (I2C Bus*)
Operating clock frequency: 400kHz
Low Power consumption
: Standby: 2 µA (max.)
: Active (Read): 0.5 mA (max.)
Automatic page write mode: 16 Bytes
Read mode: Sequential Read and random read
Erase/Write cycles: 105 cycles (Page Write)
WLCSP5, 1.20x0.80
Data Retention: 20 years
Shipped Data Pattern: FFh
High reliability: Adopts proprietary symmetric memory array configuration (USP6947325)
Hardware write protect feature
Noise filters connected to SCL and SDA pins
Incorporates a feature to prohibit write operations under low voltage conditions.

4) Acknowledge Bit (ACK)
The Acknowledge Bit is used to indicate a successful byte data transfer. The receiver sends a zero to
acknowledge that it has received each word (Device Code, Slave Address etc) from the transmitter.

5) Device addressing
To transmit between the bus master and slave device (EEPROM), the master must send a Start condition
to the EEPROM. The device address word of the EEPROM consists of 7-bit Device address code and
1-bit read/write code. By sending these, it becomes possible to communicate between the bus master
and the EEPROM.
The upper 4-bit of the device address word are called the Device Code, the Device Code of the EEPROM
uses 1010b fixed code. This device does not have the Slave address.
The 8th bit is the read/write bit. The bit is set to 1 for Read operation and 0 for Write operation. If a match
occurs on the Device Code, the corresponding device gives an acknowledgement on SDA during the 9th
bit time. If device dose not match the Device Code, it deselects itself from the bus, and goes into the
Standby mode. Use the Random Read command when you execute reading after the slave device was
switched.
