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) * I2C Bus is a trademark of Philips Corporation. * This product is licensed from Silicon Storage Technology, Inc.
