概要

Description

The FM24C64B-GTR is a 64 Kbit (8 Kbyte) Ferroelectric Random Access Memory (FRAM) device designed for non-volatile data storage. Unlike traditional EEPROM, FRAM offers faster read and write speeds, higher endurance (up to 10 trillion read/write cycles), and lower power consumption. It operates on a voltage range of 2.7V to 3.6V and communicates via an I²C interface, making it compatible with various microcontrollers and digital systems.
Key features include a fast write time (typically around 10 ns), automatic write protection, and a wide temperature range for reliability in different environments. The FM24C64B-GTR is ideal for applications requiring frequent data updates, such as in smart meters, industrial controls, and consumer electronics, where data retention and performance are critical. Its non-volatile nature ensures that data is preserved even during power loss.

Features

The FM24C64B-GTR is a 64Kb (8K x 8) non-volatile ferroelectric random-access memory (FRAM) device. Key features include:
- Non-Volatile Memory: Retains data without power, with unlimited read/write cycles.
- Fast Write Speed: Write operations are significantly faster than traditional EEPROM, often in the order of nanoseconds.
- Low Power Consumption: Operates on low voltage (1.8V to 3.6V), making it suitable for battery-powered applications.
- SPI Interface: Supports a Serial Peripheral Interface (SPI) for easy integration with microcontrollers.
- Wide Temperature Range: Operates reliably in a broad range of temperatures, typically from -40°C to +85°C.
- High Endurance: Capable of over 10 trillion read/write cycles, ensuring long-term reliability.
- Small Package Sizes: Available in compact packaging options for space-constrained designs.
These features make the FM24C64B-GTR ideal for applications requiring fast, reliable, and low-power memory solutions, such as data logging, smart meters, and industrial automation.
