Microchip 47L04-I/SN

512 x 8400 нс-40°C ~ 85°C (TA)

Overview

The 47L04-I/SN from Microchip is a 4Kbit, I2C serial EERAM in 8 pin SOIC package. This SRAM with EEPROM backup is designed to support a bidirectional two-wire bus and data transmission protocol (I2C). It provides infinite read and write cycles to the SRAM while EEPROM cells provide high-endurance non-volatile 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.
