Inc.

47L04/47C04/47L16/47C16 (47XXX) is a 4/16 Kbit

SRAM with EEPROM backup. The device is organized

as 512 x 8 bits or 2,048 x 8 bits of memory, and

utilizes the I2C serial interface. The 47XXX provides

infinite read and write cycles to the SRAM while

EEPROM cells provide high-endurance nonvolatile

storage of data. With an external capacitor, SRAM

data is automatically transferred to the EEPROM upon

loss of power. Data can also be transferred manually

by using either the Hardware Store pin or software

control. Upon power-up, the EEPROM data is

automatically recalled to the SRAM. Recall can also

be initiated through software control.

The 47XXX is available in the 8-lead PDIP, SOIC, and

TSSOP packages.
