Working Principles

The BR35H128FJ-WCE2 utilizes flash memory technology to store and retrieve data. It employs a Serial Peripheral Interface (SPI) for communication with the host device. The IC operates by sending commands and data through the SPI interface, which are then stored in the non-volatile memory cells. The stored data can be read back at any time, and the IC supports both individual byte-level and block-level erase operations.

Detailed Application Field Plans

The BR35H128FJ-WCE2 is suitable for a wide range of applications that require non-volatile data storage. Some potential application fields include:

1. Consumer Electronics: Used in smartphones, tablets, digital cameras, and portable media players for storing user data, firmware, and system settings.
2. Automotive: Integrated into automotive systems for storing critical data such as engine parameters, vehicle diagnostics, and infotainment system configurations.
3. Industrial Automation: Employed in industrial control systems, PLCs, and robotics for storing program code, configuration data, and logged information.
4. Medical Devices: Utilized in medical equipment for storing patient data, device settings, and firmware updates.
5. Internet of Things (IoT): Incorporated into IoT devices for data logging, sensor calibration, and firmware storage.
