Description
The FM24CL16B-G from Infineon is a 16-Kbit (2K × 8-bit) non-volatile Ferroelectric RAM (FRAM) designed to provide the performance of RAM with the persistence of non-volatile storage. By eliminating the typical write-delay overhead associated with EEPROM and Flash technologies, this device performs write operations at full bus speed. It is engineered for applications that require extreme endurance, offering up to 1014 read/write cycles, which is vastly superior to traditional non-volatile memory alternatives.
Because FRAM does not require an internally elevated voltage to perform write operations, the FM24CL16B-G exhibits significantly lower power consumption during writes. It serves as an ideal drop-in hardware replacement for serial EEPROMs, supporting both legacy 100 kHz/400 kHz timings and high-speed operation up to 1 MHz. With a robust operating temperature range of -40°C to +85°C and reliable data retention for over 150 years, this memory IC is perfect for mission-critical industrial, automotive, and data-logging applications.
Key Features
- High Endurance: Supports up to 1014 read/write cycles, offering 100 million times more cycles than standard EEPROM.
- NoDelay™ Writes: Data is written to the memory array immediately; no write-polling or bus-wait delays required.
- High-Speed I²C Interface: Compatible with 100 kHz, 400 kHz, and 1 MHz bus speeds.
- Power Efficient: Low active current of 100µA at 100kHz and extremely low typical standby current of 3µA.
- Wide Operating Range: Operates between 2.7V and 3.65V across an industrial temperature range of -40°C to +85°C.
- Drop-in Replacement: Designed as a direct hardware replacement for standard 16-Kbit serial EEPROMs.
Applications
- Industrial Instrumentation: Reliable storage for calibration data and operational parameters in harsh environments.
- Data Logging: Ideal for high-frequency recording of sensor data where write cycles would exhaust standard Flash/EEPROM.
- Automotive Electronics: Robust performance for persistent data tracking and safety-critical settings.
- Embedded Systems: High-speed buffer and state-storage for microcontrollers requiring instant data persistence.
