FM24W256-GTR

The FM24W256-GTR is a non-volatile memory device produced by Ramtron, designed to provide reliable data storage with a unique combination of features. This memory chip is part of the Ferroelectric Random Access Memory (FRAM) family, which utilizes ferroelectric materials to achieve non-volatility, meaning it retains data even when power is removed.

Key Features:

1. Memory Capacity: The FM24W256-GTR offers a storage capacity of 256 kilobits (32 kilobytes), making it suitable for applications that require moderate amounts of data retention without the need for frequent rewrites.

2. Interface: The device communicates via a Serial Peripheral Interface (SPI), which allows for high-speed data transfer. The SPI interface is widely used in embedded systems, making the FM24W256-GTR compatible with a variety of microcontrollers and processors.

3. Data Retention: One of the standout features of the FM24W256-GTR is its impressive data retention capability. It can retain data for over 100 years at room temperature, ensuring that critical information is preserved over long periods without power.

4. Write Endurance: The FRAM technology used in this chip allows for an exceptionally high write endurance, rated at over 10 trillion read/write cycles. This makes it ideal for applications that require frequent updates to stored data, such as logging and real-time data acquisition.

5. Low Power Consumption: The FM24W256-GTR is designed for low power operation, making it suitable for battery-powered devices. It consumes significantly less power during both read and write operations compared to traditional EEPROM and Flash memory.

6. Operating Voltage: The device operates within a voltage range of 2.7V to 3.6V, which is standard for many low-power applications. This flexibility allows it to be used in various electronic designs.

7. Package Type: The FM24W256-GTR is typically available in a compact 8-pin SOIC (Small Outline Integrated Circuit) package, which is suitable for surface mount technology (SMT). This compact form factor is advantageous for space-constrained applications.

8. Temperature Range: The chip is designed to operate in a wide temperature range, typically from -40°C to +85°C, making it suitable for industrial and automotive applications where environmental conditions can vary significantly.

Applications:

The FM24W256-GTR is ideal for a variety of applications, including:

• Data Logging: Its high endurance and non-volatility make it perfect for data logging applications where data must be recorded frequently and retained over time.
• Industrial Control: Used in automation systems where reliable data storage is critical for operational integrity.
• Consumer Electronics: Suitable for devices that require configuration settings or user preferences to be stored without loss during power outages.
• Medical Devices: Its reliability and long data retention make it a good fit for medical equipment that requires accurate and persistent data storage.

In summary, the FM24W256-GTR from Ramtron is a versatile and robust memory solution that combines the benefits of non-volatility, high endurance, and low power consumption, making it an excellent choice for a wide range of applications in modern electronic systems.
