STMicroelectronics M93S56-WBN6 EEPROM

The M93S56-WBN6 is a 4 Kbit (512 x 8) serial Electrically Erasable Programmable Memory (EEPROM) component from STMicroelectronics, renowned for its reliable data storage and versatile applications. This device operates across a wide voltage range of 2.5V to 5.5V, making it ideal for a variety of industrial, automotive, and consumer electronics where data integrity and retention are critical.

Featuring a high-speed SPI bus interface, the M93S56-WBN6 allows for efficient communication with microcontrollers and is capable of clock frequencies up to 10 MHz. This enables rapid data transfer, which is essential for applications that require quick data access and updates. The device also includes a Write Control pin to protect against inadvertent write operations, ensuring that your data remains safe during unexpected events such as power surges or dips.

The EEPROM is organized as 512 words of 8 bits each, which can be written or read individually to provide maximum flexibility in data management. This granularity allows for precise control over data storage and retrieval processes, which is especially useful for configuration settings, device calibration data, or storing small amounts of information that need frequent updating.

One of the key features of the M93S56-WBN6 is its endurance, with the EEPROM capable of withstanding up to 1 million write cycles and a data retention period of over 40 years. This durability ensures that the device will continue to function reliably over the long term, even under demanding conditions.

To ensure secure data storage, the M93S56-WBN6 comes equipped with a hardware and software protection scheme to prevent accidental write operations. It also supports a Write Disable instruction for hardware protection and a Write Enable instruction for write operations, giving users full control over the protection status of the device.

With its compact SO-8N packaging, the M93S56-WBN6 is designed to occupy minimal space on printed circuit boards, making it an excellent choice for space-constrained applications. Whether you are designing a sophisticated industrial control system or a simple consumer gadget, the M93S56-WBN6 offers a reliable and flexible solution for your non-volatile memory needs.
