The BR24T128F-WE2 is a high-reliability serial EEPROM (Electrically Erasable Programmable Read-Only Memory) from ROHM with a 128 Kbit memory capacity and data retention rate of 20 years. It is compatible with a standard I2C bus, meaning it can be used with both ROHM and non-ROHM devices. The device operates with a voltage range of 1.8 to 5.5V, with a maximum current consumption of 160uA. It has advanced features such as Block Write, Erase/Write cycle endurance of 10,000 times, and a maximum data transfer rate of 400kbps. It features dual-pointer read and write support, meaning data can be written or read quickly in continuous or skip mode. The device also features EEPROM protection functions. The BR24T128F-WE2 is suitable for automotive, industrial, and medical applications.
