ST24C64W6 - 64 Kbit Serial I²C Bus EEPROM

The ST24C64W6 is a 64 Kbit Electrically Erasable Programmable Read-Only Memory (EEPROM) product from STMicroelectronics, designed for optimal storage solutions in a wide array of electronic applications. This memory device operates with a supply voltage range of 2.5V to 5.5V, making it highly versatile for different power environments.

Featuring a 64 Kbit (8 Kbyte) capacity, the ST24C64W6 is organized as 8 blocks of 1 Kbyte (8 bits) each. It utilizes the I²C serial interface for communication, which is a widely adopted protocol that enables easy integration into most microcontroller-based systems. The I²C interface supports up to 400 kHz (Fast Mode) and 100 kHz (Standard Mode) clock frequencies, ensuring compatibility with both high-speed and legacy systems.

This EEPROM device boasts an impressive write cycle endurance, with STMicroelectronics guaranteeing up to 1 million write cycles per byte and a data retention period of 40 years. These features make the ST24C64W6 an excellent choice for applications requiring frequent data updates or long-term data preservation.

The ST24C64W6 offers flexible write protection mechanisms. The hardware Write Control (WC) pin can be used to prevent accidental data overwrites. Additionally, a portion of the memory array can be permanently locked in read-only mode by programming the status register, providing an extra layer of security for critical data.

STMicroelectronics has designed the ST24C64W6 with a byte and page write capability of up to 32 bytes, making it efficient for both small data updates and larger data block writes. This flexibility enhances the overall performance of the device in various application scenarios.

Furthermore, the ST24C64W6 is available in a variety of packages, including SO8, TSSOP8, and WLCSP, to accommodate different space constraints and assembly requirements. Its operational temperature range from -40°C to +85°C ensures reliability across diverse environmental conditions.

In summary, the ST24C64W6 from STMicroelectronics is a robust and reliable EEPROM solution, ideal for applications that require serial I²C communication, low power consumption, and a flexible, secure data storage system.
