FM24W256-GTR Integrated Circuits (ICs)

The FM24W256-GTR is a Serial FRAM memory device designed and manufactured by Fujitsu Semiconductor Ltd. It provides high-speed, low-power non-volatile FRAM memory solutions compatible with the industry-standard SPI protocol. The device comes in a variety of densities and can store up to 32Mbits of data. The product is suited to a wide range of applications from industrial and energy-harvesting applications to automotive and even consumer electronics.

The FM24W256-GTR provides two main benefits for designers. Firstly, it is very quick and able to read and write data in 16-bit or 32-bit bursts, achieving a maximum read speed of 40MHz. This makes the device suitable for applications that require high-speed data transfers. Secondly, it consumes very little power (2.5mW) even when operating at the maximum speed. This makes it suitable for energy-sensitive applications.

The FM24W256-GTR is compliant with SPI, making it a simple to integrate into existing architectures. It also supports user-programmable protocol features that allow the device to be customized for specific applications. In addition, the device supports numerous features including durable write protection features, write protection features that allow you to easily control the location of write protection, and an Internal Battery Backup feature that provides additional protection when power is lost.

In terms of its working principle, the FM24W256-GTR is a 3-wire Serial FRAM memory device based on the industry-standard SPI protocol. When the device is enabled, it functions as a master device and initiates communication with the slave device, as it can support up to four slaves at a time. The data is transmitted through the serial interface over two wires, and the third wire is used for clock synchronization. The device provides a full set of status registers and interrupts to manage the transaction process. Once the data is transmitted, it is written to the non-volatile FRAM memory. Upon completion of the operation, the device returns an acknowledgement to the master device.

The FM24W256-GTR is a reliable and versatile non-volatile memory device suitable for a variety of applications. It is designed to be both fast and power efficient, making it a great choice for applications that require high-speed data transfers or are energy-sensitive. In addition, it is compliant with SPI and supports a wide range of features that allow it to be customized for specific applications.
