Microchip 47L16-E/SN, 16kbit EERAM, 400ns 8-Pin SOIC Serial-I2C

The Microchip Technology Inc 47L16 EERAM is a 16Kbit SRAM with EEPROM Backup. The I2C EERAM Memory is a Low-Cost NVSRAM that Eliminates the Need for an External Battery to Retain Data. The device is organized as 2048 x 8 bits and utilizes the I2C serial interface. The 47L16 provides infinite read and write cycles to the SRAM while the EEPROM cells provide high endurance non-volatile storage of Data. With an external capacitor, SRAM data is automatically transferred to the EEPROM upon power-loss.Additional Features: 16Kbit SRAM with EEPROM Back Up Automatic Store to EEPROM upon power-down (using optional external capacitor) Automatic Recall to SRAM Array upon power-up Hardware Store Pin for manual Store Operations Software commands for initiating Store and Recall Operations Store Time 40ms (max) 2.7V -3.6V Operation High-Speed I2C Interface (Up to 1MHz)
