FM24VN10-GTR

FM24VN10-GTR is a 1‑Mbit serial nonvolatile memory based on ferroelectric RAM (FRAM). It provides persistent storage with extremely high write endurance and fast random access, making it suitable for frequent data logging, configuration data, and state retention in embedded systems.
Key points:
- Interface: 2‑wire I2C serial interface (standard/fast modes) with address pins for bus multiplexing.
- Capacity/organization: about 128 KB of memory accessible as 8‑bit bytes.
- Performance: fast reads; writes are quick and can be done in small page-sized blocks (typical page writes on FRAM are 16 bytes); endurance ≫ traditional EEPROM (virtually unlimited write cycles).
- Power and usage: low power operation with options suitable for microcontroller integration; typically programmable and read/write operations are deterministic with simple timing.
- Features: hardware write protection, data retention over long periods, multiple devices on the same bus.
Note: exact voltage range, timing, temperature, and package options vary by variant. Consult the FM24VN10-GTR datasheet for precise specifications and recommended operating conditions.
