Memory devices are essential components of computing devices, enabling the rapid storage and retrieval of data for processor-intensive applications. The FM25V20A-DGQTR is a specialized form of serial-mode 8-bit nonvolatile static random access memory (SRAM). It is designed to provide an efficient combination of cost, functionality, and performance for a variety of applications.

The FM25V20A-DGQTR is an 8 KB device that is split into pages. Each page is organized into 256 × 8 bytes of nonvolatile SRAM. The device includes an internal 128-byte Register Map containing registers that control the various features and functions of the chip. It runs on a single power supply of 2.7V to 3.6V.

The primary function of the FM25V20A-DGQTR is to provide low-voltage, nonvolatile static random access memory (SRAM). It reads and writes data in 256, 8-bit words. Data is stored in the device during both active and standby modes. The device can operate at transfer rates up to 10MHz and is optimized for low-power applications. Its small form factor and robust design make it suitable for use in a variety of applications.

The main application fields of FM25V20A-DGQTR are industrial applications, consumer applications, automotive applications, and medical applications. It is suitable for a wide range of applications, including electronic control units (ECUs), electronic circuits and equations, calibration data storage, identification tags, smart cards, data logging, automotive safety systems and other embedded devices.

The FM25V20A-DGQTR operates by accessing the serial address and data bus. A valid write enables the device to store the data in the memory. The data can then be read back from memory by executing a valid read command. During power-down or standby modes, the data remains stored while the chip consumes minimal power. The chip can operate at temperatures ranging from -40°C to +85°C.

The FM25V20A-DGQTR features various features to ensure reliable data storage and retrieval, including hardware data protection, hardware readout protection, hardware write protection, hardware reset, and hardware enable. The hardware data protection feature prevents accidental data corruption from external systems. The hardware readout protection prevents unauthorized access to the data stored in the device. The hardware write protection prevents accidental data erasure or alteration. The hardware reset feature allows for a complete reset in the event of an unexpected issue. The hardware enable feature allows the user to selectively enable and disable the device, further enhancing security.

The FM25V20A-DGQTR is an ideal memory device for applications requiring low-power operation, small form factor, and reliable data storage. Its cost-effectiveness and high performance make it suitable for various industrial, consumer, automotive and medical applications. It is an effective solution for a range of applications, and offers a robust and reliable memory solution at an attractive price point.
