47C04T-I/ST

The Microchip Technology Inc 47C04 EERAM offers a reliable and cost-effective solution for storing data without the need for an external battery. With a capacity of 4Kbits, this NVSRAM device combines the speed of SRAM with the non-volatile capabilities of EEPROM. This makes it ideal for applications that require frequent read and write operations while ensuring data integrity during power loss events. The I2C serial interface simplifies communication with the device, allowing for seamless integration into various systems
