LE24LB1283
CMOS IC
Two Wire Serial Interface
EEPROM (128k EEPROM)
Overview
The LE24LB1283 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: 128k bits (16k × 8 bits)
• Single supply voltage: 1.8V 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: 64 Bytes
• Read mode: Sequential read and random read
• Erase/Write cycles: 106 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 : LE24LB1283M : MFP8(225mil)

Pin Functions
SCL (serial clock input) pin
The SCL pin is a serial clock input pin that processes signals at the rising and falling edges of SCL clock signals.
The SCL pin must be pulled up by a resistor to the VDD level and wired-ORed with an open drain (or open collector)
output device for use.
SDA (serial data input/output) pin
The SDA pin is used to transfer serial data to the input/output, and it consists of a signal input pin and n-channel
transistor open drain output pin.
Like the SCL pin, the SDA pin must be pulled up by a resistor to the VDD level and wired-ORed with an open drain
(or open collector) output device for use.
WP (write protect) pin
When the WP pin is high, write protection is enabled, and writing into the all memory areas is prohibited. When the
pin is low, writing is possible to all memory areas. Read operations can be performed regardless of the WP pin status.
S0, S1, S2 (slave device address) pin
An individual product is selected by using S0 pin, S1 pin and S2 pin when it connects on the same bus. This product
can set the slave address by connecting S0 pin, S1 pin and S2 pin with VDD or GND when the substrate is mounted. It
is necessary to fix the terminal not used as a slave address to VDD or GND on the substrate.

7-3. Sequential read
In this mode, the data is read continuously, and sequential read operations can be performed with both current address
read and random read. If, after the 8-bit data has been output, acknowledge “0” is input and reading is continued
without issuing the stop condition, the address is incremented, and the data of the next address is output.
If acknowledge “0” continues to be input after the data has been output in this way, the data is successively output
while the address is incremented. When the last address is reached, it is rolled over to address 0, and the data
continues to be read. As with current address read and random read, the operation is completed by inputting the stop
condition without sending an acknowledge signal.
