R1EX24256ATB00I - Two-wire serial interface 256k EEPROM

Download the R1EX24256ATB00I datasheet PDF. This datasheet also covers the R1EX24256ASA00I variant, as both devices belong to the same two-wire serial interface 256k eeprom family and are provided as variant models within a single manufacturer datasheet.

General Description

R1EX24xxx series are two-wire serial interface EEPROM (Electrically Erasable and Programmable ROM).

They realize high speed, low power consumption and a high level of reliability by employing advanced MNOS memory technology and CMOS process and low voltage circuitry technology.

Key Features

  • Single supply: 1.8 V to 5.5 V Two-wire serial interface (I2C serial bus) Clock frequency: 400 kHz Power dissipation:  Standby: 2 µA (max)  Active (Read): 1 mA (max)  Active (Write): 5 mA (max) Automatic page write: 64-byte/page Write cycle time: 5 ms Endurance: 106 Cycles Data retention: 10 Years.
  • Preliminary: The specifications of this device are subject to change without notice. Please contact your nearest Rene.
