STMicroelectronics M24C64-WMN6 EEPROM

The M24C64-WMN6 is a 64-Kbit I²C-compatible EEPROM (Electrically Erasable Programmable Read-Only Memory) produced by STMicroelectronics. This device is part of STMicroelectronics’ serial EEPROM family, which is designed for flexible, non-volatile storage applications. The M24C64-WMN6 is optimized for use in a wide range of industrial, automotive, and consumer electronics, where reliable and dependable data storage is crucial.

With a memory density of 64 Kbits, the M24C64-WMN6 allows for storage of 8,192 bytes of data. It utilizes a two-wire I²C serial interface for communication, which supports bus speeds of up to 400 kHz, making it suitable for applications that require fast data transfer without compromising power efficiency.

The EEPROM is organized as 32 blocks of 256 x 8-bit, each of which can be independently programmed in write cycles of up to 5 ms. The flexibility of the M24C64-WMN6 is evident in its byte and page write capabilities – from one byte to 32 bytes, enhancing performance when managing data updates and storage.

One of the key features of the M24C64-WMN6 is its compatibility with the extended I²C bus mode, which includes a 2 MHz protocol. Additionally, the device supports a hardware write control feature through its Write Control input pin. This allows for the prevention of inadvertent writes, thus safeguarding the stored data.

STMicroelectronics ensures reliability and endurance with the M24C64-WMN6 by guaranteeing 1 million write cycles per byte and a data retention period of 40 years. These specifications make it a robust choice for critical applications that require frequent data updates and long-term data preservation.

The M24C64-WMN6 is available in an 8-pin SOIC package, making it convenient for PCB layouts and compatible with standard surface-mount processes. Its operating voltage ranges from 2.5 V to 5.5 V, which allows for a wide range of applications and ensures compatibility with most microcontrollers and digital systems.

Overall, the M24C64-WMN6 from STMicroelectronics represents a reliable and efficient solution for designers looking to implement non-volatile memory storage with a proven track record of stability and endurance.
