LE24162LBXA
CMOS IC
Two Wire Serial Interface
EEPROM (16k EEPROM)
Overview
The LE24162LBXA 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 (to read)
Operating temperature: -40 to +85ºC
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 (Page write)
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 : WLFCP6(0.80 × 1.20)
