The M93C46-WBN6 is a highly reliable and secure serial EEPROM memory device that incorporates all of the security, protection, nonvolatility and performance that today\'s embedded system designers require. Applications include automotive, consumer, industrial, medical and military/aerospace.

The M93C46-WBN6 provides 1,024 bits of electrically erasable programmable read-only memory (EEPROM), organized as 128 × 8 bits. It is available in the popular 3-wire Serial Peripheral Interface (SPI) 16-contact WSON (8 mm) packages for surface-mount applications.

The M93C46-WBN6 has an advanced protection feature called "On-Chip Security Lockout" which prevents unauthorized access to code and data stored in the EEPROM. The protection is provided by the internal design of the device and allows the user to configure a password or key that is necessary to access the contents of the memory. This feature helps protect against unwanted software tampering, malicious code insertion and hardware disassembly. Additionally, the M93C46-WBN6 has an additional protection feature called "Secure Synchronous Interface Mode," which provides an extra layer of protection by using an encryption key to authorize access to the device.

Due to its reliable and robust security features, the M93C46-WBN6 can be used in applications where data and code integrity is essential. It is ideal for the deployment of secure boot systems, code and data encryption, secure authentication, signature verification and software license management.

The M93C46-WBN6 also provides a nonvolatile storage solution for data that needs protection from power cycles, tamper attempts and accidental overwrites. In addition to its security features, the device is capable of supporting write times up to 1.5 milliseconds and has a typical write endurance of 1 million write cycles.

The working principle of the M93C46-WBN6 is based on the Non-Volatile Memory (NVM) architecture and is divided into two parts for data storage and data management. The memory is divided into "Code" and "Data" segments, with the code portion assigned to storing instructions that are executed by the system. The data segment is used to store information that is accessed by the system, such as configuration parameters, sensor values, etc.

The M93C46-WBN6 integrates a simple serial communication interface that enables it to be connected to a microcontroller or a microprocessor. The device can be controlled from the microcontroller or microprocessor through a set of instructions. The instructions may be used to read and write data, access the memory for code, erase the memory and configure the memory for secure access. Additionally, the device can be powered down in order to protect the data and the code stored in it.

In conclusion, the M93C46-WBN6 is a reliable, secure and nonvolatile memory solution specifically designed for applications where data integrity is essential. Its advanced security features and nonvolatile architecture make it ideal for a wide range of applications, including automotive, consumer, industrial, medical and military/aerospace.
