M95256-WBN6 is a type of memory integrated circuit (IC) developed bySTMicroelectronics. It is a 16K-bit, three-wire serial static random access memory(SRAM) that operates from a single 2.7V to 3.6V supply. In addition, it is designedfor low power consumption, moderate speed and low operating temperature,making it an ideal solution for many common applications.

The M95256-WBN6 is a non-volatile memory and stores data without an externalpower source. This feature allows it to be used in battery-operated devices, suchas calculators, digital cameras and portable electronics. The device also includesAnnelle-Dings, a low-level read/write algorithm, which helps reduce batteryconsumption and enhances product reliability.

The M95256-WBN6 features three I/O pins (WP, RD and WR), as well as universaland asynchronous address and data buses (A0-A13, P0-P7). It supports both Synchronous and Asynchronous Serial Peripheral Interface (SPI) and iscompatible with 3-wire SPI, 4-wire SPI and I2C communication protocols. Thedevice can be configured for either byte-wide (8-bit) or word-wide (16-bit)access.

In terms of its working mechanism, the M95256-WBN6 uses static RAM technique,in which data can be stored indefinitely by simply keeping the power on. It storeseach bit as a static (stuck) charge on a transistor gate. To read a bit, the supplyvoltage is applied to the transistor gate, causing the charge to leak off. Thisleaking off signal is then amplified and the data is converted into a logic level signal. To write a bit, the proper voltage is applied to the gate, and the charge is either kept or dissipated according to the logic level desired.

The M95256-WBN6 is widely used in multiple areas, such as medical devices,industrial automation, automotive system, gaming devices, portable electronicdevices, sensor networks and embedded systems. It is used in a variety ofapplications, including non-volatile storage, code protection, persistent storageand low-power SRAM backup. The device is also used in data logging andsecurity solutions due to its low power and reliable operation.

In conclusion, the M95256-WBN6 is a versatile, low-power and low-cost SRAMIC solution, providing excellent options for multiple application use. Itsworking principle is based on static RAM technique which makes it an idealchoice for battery-operated devices and applications where reliable anduninterrupted storage of data is required.
