STMicroelectronics M93C46-WMN6TP EEPROM

The M93C46-WMN6TP is a robust and versatile serial EEPROM (Electrically Erasable Programmable Read-Only Memory) device from the renowned semiconductor manufacturer, STMicroelectronics. This product offers a compact storage solution for applications that require data retention without power, and it is designed to deliver high performance, reliability, and ease of integration into various electronic systems.

With a storage capacity of 1 Kbit, the M93C46-WMN6TP is organized as 128 x 8 or 64 x 16 bits, selectable through an external pin. This flexibility allows designers to choose the optimal data width for their specific application requirements. The device operates over a wide voltage range of 2.5V to 5.5V, making it suitable for both 3V and 5V systems, and it is capable of enduring a million write cycles with a data retention period of 40 years, ensuring long-term reliability of stored data.

The M93C46-WMN6TP features a Serial Peripheral Interface (SPI) bus, which simplifies the connection to microcontrollers and other digital systems. The SPI bus protocol supports high-speed data transfer, contributing to efficient system performance. Additionally, the EEPROM comes in a miniature 8-pin SOIC package (WMN suffix), which is ideal for space-constrained applications.

Among its key features, the M93C46-WMN6TP offers write protection mechanisms, including hardware and software write protect options. These features prevent accidental data alteration, which is critical for applications where data integrity is paramount. The device also supports a Write Disable instruction for further protection during high-voltage operations, such as during system power-up or power-down transitions.

The M93C46-WMN6TP is a perfect choice for a range of applications, including but not limited to, portable devices, medical equipment, automotive systems, and industrial control units. Its reliability, coupled with STMicroelectronics' commitment to quality, makes it a preferred choice for designers looking for a non-volatile memory solution that they can trust to preserve critical data across power cycles.
