Description
The FM25L16B-GTR from Infineon (Cypress) is a 16-Kbit (2K × 8-bit) Ferroelectric Random Access Memory (F-RAM) device. Unlike traditional EEPROM or Flash memory, F-RAM utilizes ferroelectric technology to provide near-instantaneous write speeds and virtually unlimited read/write endurance. This makes it an ideal solution for applications requiring high-frequency data logging, frequent status updates, or mission-critical persistent storage in industrial, automotive, and consumer electronics.
Featuring an SPI (Serial Peripheral Interface), the FM25L16B-GTR allows for efficient, high-speed communication with a wide array of microcontrollers. Because F-RAM writes at bus speed with no “soak time” or page write delay, it is often used as a direct replacement for EEPROM in systems where power-loss protection and high-cycle reliability are essential. The device is housed in a compact 8-pin SOIC surface-mount package, ensuring easy integration into modern high-density PCB designs.
Key Features
- F-RAM Technology: Offers virtually infinite endurance (up to 10^14 read/write cycles).
- Fast Write Performance: No-delay write operations; writes occur at bus speed with no page-write cycle time.
- Low Power: Extremely low power consumption for both read and write operations.
- SPI Interface: Industry-standard serial interface for simple, high-speed integration.
- High Reliability: Exceptional data retention and immunity to the wear-out mechanisms common in Flash/EEPROM technologies.
Applications
- Industrial Controllers: Real-time storage of process data and machine status.
- Data Logging: High-frequency recording of sensor readings without memory wear-out.
- Metering: Critical storage for utility meters requiring continuous data updates.
- Embedded Systems: Reliable parameter, configuration, and black-box event logging.
