FM25L16B-G Typical application Circuitry

FM25L16B-G

FM25L16B-G is a 16-Kbit (2K × 8) Serial (SPI) F-RAM, a type of non-volatile memory that leverages ferroelectric process technology. F-RAM is known for its fast write speeds, high endurance, and low power consumption, making it particularly suitable for applications requiring frequent or rapid data storage without the long write times associated with traditional non-volatile memories like EEPROM or flash.

Application Scenarios for FM25L16B-G

1. Automotive Electronics: For storing critical data that must be preserved across power cycles, such as odometer and error code records.

2. Wearable Health Devices: In devices that need to frequently update health monitoring data while conserving battery life.

3. Industrial Automation: For logging process data that must be reliably stored immediately, such as in PLCs (Programmable Logic Controllers).

Parameter Features of FM25L16B-G

- Memory Size: 16-Kbit storage capacity, organized as 2K × 8 bits, offering adequate space for various data storage requirements.

- SPI Interface: Supports Serial Peripheral Interface with a maximum frequency of 20 MHz, facilitating fast data transfer.

- Write Endurance: Extremely high write endurance, capable of 10^14 write cycles, ensuring reliability and longevity.

- Data Retention: Provides a data retention period of 151 years, ensuring long-term data integrity.

Detailed Circuit Connection Using FM25L16B-G

Application Scenario: Data Logging in an Industrial Automation System

1. Power Supply Connections: Connect the VDD (pin 8) of the FM25L16B-G to a stable 3.3V power source. To provide a shared ground reference, connect pin 4 of the VSS to the system ground.

2. SPI Communication Lines:

- Serial Clock (SCK, pin 6) should be connected to the SPI clock line from the automation system's microcontroller or controller unit.

- To send commands and data to the F-RAM, the microcontroller's Master Out Slave In (MOSI) connection is connected to Serial Input (SI, pin 5).

- To receive data from the F-RAM, the microcontroller's Master In Slave Out (MISO) line must be connected to the Serial Output (SO, pin 2). - Chip Select (\CS, pin 7) must be connected to a dedicated control line (GPIO) on the microcontroller to enable and disable the F-RAM device during SPI communication.

3. Write Protection and Hold Features:

- Write Protect (WP, pin 3) can be tied to VDD if write protection is not utilized; otherwise, it can be toggled by another GPIO pin for enabling/disabling write operations as needed.

- Hold (HOLD, pin 1) can be connected to VDD to keep the device active; if the hold function is required, it can be controlled via a GPIO pin to pause the operation without resetting the serial sequence.

Considerations for Circuit Design

1. Stable Power Supply: To avoid data corruption, make sure the FM25L16B-G's power supply is stable and falls within the designated voltage range.

2. SPI Bus Management: Properly manage the SPI bus, especially if multiple devices share the bus. Ensure that the FM25L16B-G is only active when its \CS line is low, to avoid bus contention.

3. Decoupling Capacitors: Place a decoupling capacitor close to the FM25L16B-G's VDD pin to filter out power supply noise and provide a stable operating environment.

4. PCB Layout: Minimize the trace lengths between the microcontroller and the FM25L16B-G to reduce parasitic capacitances and inductances, improving signal integrity, especially at higher SPI clock speeds.

Integrating the FM25L16B-G into an industrial automation system for data logging ensures immediate and reliable storage of critical process data, leveraging its rapid write capability and high endurance for effective real-time data management.
