LE2416DXA
16 kb I2C CMOS Serial EEPROM
Overview
The LE2416DXA is two-wire serial interface EEPROM (Electrically
Erasable and Programmable ROM). This device realizes high speed and a
high level reliability by 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.

LE2416DXA
Functional Description
The device supports the I2C protocol. Any device that sends data on to the bus is defined to be a transmitter,
and any device that reads the data to a receiver. The device that controls the data transfer is known as the
bus master, and the other as the slave device.
1) Start Condition
A Start condition needs to start the EEPROM operation, it is to set falling edge of the SDA while the SCL
is stable in the high status.
2) Stop Condition
A Start condition is identified by rising edge of the SDA signal while the SCL is stable in the high status.
The device becomes the standby mode from a Read operation by a Stop condition. In a write sequence,
a stop condition is trigger to terminate the write data inputs and it is trigger to start the internal write cycle.
After the internally write cycle time which is specified as tWC, the device enters a standby mode.

3) Data Input
During data input, the device latches the SDA on the rising edge of the SCL. For correct the operation,
The SDA must be stable during the rising edge of the SCL.

6) Notes on write protect operation
This product prohibits all memory array writing when the WP pin is high. To ensure full write protection,
the WP is set high for all periods from the start condition to the stop condition, and the conditions below
must be satisfied.
