FM25V20A-GTR Typical application Circuitry

FM25V20A-GTR

FM25V20A-GTR is a 2-Mbit (256K × 8) Serial (SPI) F-RAM, a non-volatile memory utilizing ferroelectric process technology. F-RAM offers fast write speeds, high endurance, and low power consumption, making it ideal for data logging, industrial controls, and smart meters where data integrity and power efficiency are critical.

Application Scenarios for FM25V20A-GTR

1. Data Logging Systems: In environments with frequent power fluctuations, ensuring data integrity during unexpected power loss.

2. Industrial Control Systems: For storing configuration and process control data that must be updated frequently and instantly available upon power-up.

3. Wearable Electronics: In devices that require low power consumption and fast data access for user settings and activity data.

Parameter Features of FM25V20A-GTR

- Memory Size: 2-Mbit storage capacity, organized as 256K × 8 bits, providing ample space for various data storage needs.

- Interface: SPI (Serial Peripheral Interface) with a maximum frequency of 40 MHz, allowing for fast data transfer.

- Write Endurance: Extremely high endurance, capable of 10^14 write cycles, ensuring reliability over the device's lifespan.

- Data Retention: Offers data retention of 151 years, providing long-term data storage stability.

Detailed Circuit Connection Using FM25V20A-GTR

Application Scenario: Industrial Control System Data Storage

1. Power Supply Connection: Connect VCC (pin 8) of the FM25V20A-GTR to a stable 3.3V power source. Ground (GND, pin 4) should be connected to the system ground.

2. SPI Interface Connection:

- Join the microcontroller's SPI clock output to the Serial Clock (SCK, pin 6).

- The serial data input (SI, pin 5) and the microcontroller's SPI Master Out Slave In (MOSI) connection should be connected.

- The Serial Data Output (SO, pin 2) is received by the microcontroller over the SPI Master In Slave Out (MISO) line.

- To start and stop communication sessions, the microcontroller's Chip Select (CS, pin 7) needs to be attached to a specific GPIO pin.

3. Write Protection and Hold:

- The Write Protect (WP, pin 3) can be tied to VCC if write protection is not required; otherwise, it can be controlled via another GPIO pin for enabling/disabling write operations.

- To keep the device always on, tie the Hold (HOLD, pin 1) pin to VCC. Another GPIO pin can be used to control the hold function if it is required.

Circuit Design Considerations

1. Power Supply Stability: Ensure the power supply to the FM25V20A-GTR is stable and within the specified range to avoid data corruption.

2. SPI Bus Management: Since SPI is a shared bus, proper management is essential when multiple devices are connected. Ensure that the CS line for the FM25V20A-GTR is managed correctly to avoid bus contention.

3. Decoupling Capacitors: Place a decoupling capacitor close to the VCC pin of the FM25V20A-GTR to filter out noise and provide power supply stability.

4. PCB Layout Considerations: Minimize the length of the SPI lines and maintain impedance control, if possible, to reduce signal degradation, especially at higher SPI clock speeds.

By incorporating these design principles, the FM25V20A-GTR can be effectively utilized in industrial control systems for reliable data storage, offering the benefits of fast write operations, high endurance, and low power consumption.
