The AT24C64W-10SI-1.8 belongs to a family of memory products, such as non-volatile memory and EEPROM (electrically erasable programmable read-only memory). It is an 8-bit non-volatile memory chip with an advanced write-protection feature. It can be used in both normal operation and protects the host from accidental or malicious write operations. The chip has a 64Kb storage capacity and a maximum operating frequency of 6.144MHz.

The AT24C64W-10SI-1.8 is designed for industrial and automotive applications, such as automotive and medical systems, where high reliability, low power consumption and data retention is essential. It can store small amounts of data such as passwords, user configuration settings and calibration data. Additionally, the chip can be used for secure authentication and identification in vehicular and banking applications.

The memory chip consists of an 8-bit wide array and a 32-bit control logic that includes an address counter and register. The 8-bit data is stored in 8-byte by 128-bit pages with an address pointer. When used in conjunction with a microcontroller, the AT24C64W-10SI-1.8 can provide non-volatile storage for software code, as well as configuration and calibration parameter settings.

The chip also supports error correction codes (ECC), ensuring data integrity of stored information. It includes a flexible write protection feature that enables the user to protect parts of the memory while allowing access to other parts. The chip is programmable and can be used with several types of external serial interfaces, including an I2C interface that supports a 7-bit or 10-bit address for maximum compatibility.

The AT24C64W-10SI-1.8 has a maximum power consumption of 2.2mA and a maximum write cycle frequency of 125kHz. It has a data retention period of over 100 years, which is important for maintaining information during power loss. The chip also has EEPROM endurance rating of up to 10,000 write cycles, and is designed to last for longer periods of time in industrial applications.

In summary, the AT24C64W-10SI-1.8 is a highly reliable and versatile memory chip. It is ideal for industrial, automotive and medical applications, providing non-volatile storage with write protection and error correction codes. The chip is easy to customize and program, and its long data retention period ensures that important data is not lost in the event of power loss.
