Visão Geral
Description
Key features include a 40 MHz SPI interface for efficient data transfer, data retention of over 10 years, and an endurance of 10^14 read/write cycles. The FM25W256-GTR is robust against data corruption, offering better reliability than traditional EEPROM or Flash memory. It is ideal for applications in metering, industrial control, automotive, telecommunications, and medical devices, where data integrity and quick access are critical. The device is available in a standard 8-pin small-outline integrated circuit (SOIC) package, ensuring ease of integration into existing hardware designs.
Equivalent
1. MB85RS256TY by Fujitsu - A 256-Kbit SPI interface F-RAM.
2. MR25H256 by Everspin Technologies - A 256-Kbit SPI interface MRAM.
3. CY15B256Q by Cypress - Another 256-Kbit SPI F-RAM offering with similar specifications.
These alternatives offer similar non-volatile memory with fast write speeds and high endurance. Always verify the pin compatibility and electrical characteristics when considering replacements.
Features
1. Capacity: 256 kilobits (32K x 8).
2. Non-volatile: Retains data without power, with virtually unlimited read/write cycles.
3. Performance: No delay for read/write operations, similar to SRAM but non-volatile.
4. Interface: Uses a SPI interface for communication, supporting serial input and output.
5. Speed: Supports clock speeds up to 20 MHz for fast data access.
6. Endurance: Offers over 10 trillion (10^14) read/write cycles.
7. Supply Voltage: Operates within a range of 2.7V to 3.6V.
8. Low Power Consumption: Consumes much less power compared to EEPROM or Flash memory.
9. Package: Available in an 8-pin SOIC package.
10. Data Retention: Ensures data retention for over 10 years at 85°C.
11. Applications: Ideal for applications requiring frequent data logging, such as industrial control, metering, and medical devices.
These features make the FM25W256-GTR suitable for applications demanding reliable and enduring memory storage.
Pinout
1. CS (Chip Select): Enables the device for communication.
2. SO (Serial Data Output): Outputs data to the controller.
3. WP (Write Protect): Protects the write operations in specific memory areas.
4. VSS: Ground reference.
5. SI (Serial Data Input): Inputs data from the controller.
6. SCK (Serial Clock): Synchronizes the data transfer.
7. HOLD: Pauses serial communication without resetting the device.
8. VDD: Power supply.
These pins facilitate communication and control of the F-RAM device using an SPI interface.
