STMicroelectronics M93C46-WBN6P

The M93C46-WBN6P is a 1 Kbit (128 x 8 or 64 x 16) serial Microwire EEPROM (Electrically Erasable Programmable Read-Only Memory) produced by STMicroelectronics, a global semiconductor leader that designs, manufactures, and markets a broad spectrum of microelectronic components.

This particular EEPROM is part of the M93C46 series, which is optimized for use in a wide range of industrial, automotive, and consumer applications where reliable and cost-effective non-volatile memory storage is essential. It operates across a voltage range of 2.5V to 5.5V, making it suitable for low-power operations and compatibility with most microcontroller logic levels.

The M93C46-WBN6P features a small 8-pin PDIP (Plastic Dual In-line Package), which is widely used and suitable for through-hole mounting, thus providing robust mechanical stability. This package is ideal for applications where space is not a major constraint, and where the product may need to be removed or replaced during maintenance.

The device offers a flexible byte and page write (up to 16 bytes), which is both fast and reliable, with the write cycle being completed within 5 ms. It also boasts a high endurance, with each memory location specified to withstand at least 1 million write cycles, coupled with a data retention period of 40 years, ensuring the reliability and longevity of stored data.

Communication with the M93C46-WBN6P is established via a three-wire serial Microwire interface, which is compatible with the majority of standard microcontrollers. This serial interface not only simplifies integration but also minimizes the number of I/O lines used, which is beneficial for reducing the overall system complexity and cost.

In summary, the M93C46-WBN6P from STMicroelectronics is a robust, reliable, and cost-effective non-volatile memory solution that provides efficient data storage for a multitude of applications where durability and dependability are paramount.
