47L16 EERAM Breakout

£4.00

The 47L16 EERAM is an ingenious product from Microchip. Coupling 2kB of SRAM with 2kB of EEPROM and an emergency backup power circuit (driven by a single capacitor) gives you the ease of use and lifetime of an I2C SRAM chip with the data retention of an I2C EEPROM chip.  As soon as power is lost to the chip the backup power in the capacitor is used to write the contents of the SRAM to the EEPROM.  At power-up the SRAM is re-filled from the EEPROM backup.
