The 47L04T-I/SN is a 4 Kbit serial EERAM that provides SRAM with a nonvolatile EEPROM backup. It operates on a supply voltage range of 2.7V to 3.6V and communicates via an I2C-compatible interface at speeds up to 1 MHz. The device features automatic data storage from SRAM to the EEPROM array upon power loss and automatic recall on power-up, ensuring data integrity. With high reliability, including over one million store cycles and data retention exceeding 200 years, this EERAM is suitable for applications requiring frequent data writes and nonvolatile storage, such as data logging and system configuration.
