STMicroelectronics M93C46-WBN6 EEPROM

The M93C46-WBN6 is a 1 Kbit (128 x 8 or 64 x 16) serial access EEPROM (Electrically Erasable Programmable Read-Only Memory) produced by STMicroelectronics. This particular model is part of the M93Cxx family, which is known for its reliable and efficient non-volatile memory storage solutions. The M93C46-WBN6 utilizes the robust Microwire bus protocol and is optimized for low power consumption and high data retention, making it an ideal choice for a wide array of electronic applications.

Featuring a supply voltage range of 2.5V to 5.5V, the M93C46-WBN6 is versatile and can be integrated into both low-voltage and standard systems. Its small package size, offered in both SO and TSSOP packages, ensures that it can fit into space-constrained applications without compromising functionality.

The M93C46-WBN6 supports a write cycle time of 5ms, enabling quick data updates and efficient write operations. It also boasts a data retention period of over 40 years, along with the ability to endure 1 million write cycles, which guarantees long-term reliability for user data. This robust endurance and retention make the EEPROM a dependable choice for critical data storage requirements.

One of the key features of the M93C46-WBN6 is its self-timed write cycle with automatic erase-before-write capability. This simplifies the write operation and ensures data integrity by preventing the need for complex write sequences and reducing the risk of data corruption. Additionally, the device offers an organization of either 128 x 8 bits or 64 x 16 bits, allowing developers the flexibility to choose the best data organization for their specific application needs.

Security features are also embedded within the M93C46-WBN6, including a write protect pin and a write disable instruction for both hardware and software data protection. This ensures that sensitive information remains secure from unintended alterations. For easy integration, the device is fully compatible with the serial peripheral interface (SPI) bus, allowing for seamless connection with a wide range of microcontrollers and processors.

In conclusion, the M93C46-WBN6 from STMicroelectronics is a high-performance, reliable EEPROM solution that provides secure data storage for applications in industrial, automotive, consumer electronics, and many other fields requiring non-volatile memory storage.
