The FM24CL64B-G is one of the most widely used memories today due to its versatile application and working principles. It is a non-volatile, 64-Kbit serial static RAM (SRAM) memory chip. The chip has two main features to help make it a popular choice: its relatively fast read and write speeds, and its low operating voltage.

The FM24CL64B-G is mainly used in memory applications where data needs to be continuously restored after power interruptions or unexpected shutdowns. The chip is made up of an array of 4K x 4 bit static RAM cells, arranged as 16K x 8 that can store data even after power is turned off. The data on these cells are held in an SPI (Serial Peripheral Interface) or I2C (Inter-Integrated Circuit) interface that allows the chip to read and write information easily.

The working principle of the chip is based on the write and read operations. When data is written onto the cells, the controller first sends the address of the data to be written, followed by the data itself. On the other hand, when the data is to be read from the chip, the controller sends a command code of ‘read’ and the address of the data to be read. The microcontroller then reads the data from the chip and stores it in its internal memory.

The chip can operate at a low voltage ranging from 1.8V to 3.6V, which allows it to be used in many different types of applications. FM24CL64B-G also offers good power management, with power consumption of up to 350uA and standby current of 1uA. Additionally, the chip is temperature compensated, meaning it can recognize temperature variations and reduce power consumption when the temperature is low.

One of the main applications of the FM24CL64B-G is in remote controls, where the chip can be used to store long strings of key codes that can be read, written, or updated in real-time. In addition, the chip can be used in a variety of other applications that require data to be stored for long periods of time even when power is cut off, such as medical devices and various industrial applications.

The FM24CL64B-G is a versatile and low-power chip that is widely used in various applications. It can be used to store data and ensure that data is preserved even after power interruption or sudden shutdowns. The chip is compact and offers good power management and temperature compensation, making it a great choice for applications in a variety of different industries.
