Working Principles

The BR35H128F-WCE2 utilizes non-volatile memory technology to store and retrieve data. It employs a Serial Peripheral Interface (SPI) for communication with an external microcontroller. When data needs to be stored, the microcontroller sends the data through the SPI interface to the IC, which then writes it to the memory cells. Similarly, when data needs to be retrieved, the microcontroller sends read commands to the IC, which transfers the requested data back to the microcontroller via the SPI interface.

Detailed Application Field Plans

The BR35H128F-WCE2 can be used in various applications that require non-volatile data storage, such as: - Consumer electronics (e.g., smartphones, tablets, digital cameras) - Automotive systems (e.g., infotainment systems, instrument clusters) - Industrial equipment (e.g., data loggers, measurement devices) - Medical devices (e.g., patient monitoring systems, diagnostic equipment)
