The FM25C640UEM8 is an IC (Integrated Circuit) component manufactured by Cypress Semiconductor. This device is part of the FM25C series and is a 64Kbit (8K x 8) Serial Peripheral Interface (SPI) FRAM (Ferroelectric Random Access Memory).
Key features of the FM25C640UEM8 include:
1. Non-volatile Memory: Unlike traditional EEPROM (Electrically Erasable Programmable Read-Only Memory), the FM25C640UEM8 utilizes Ferroelectric Random Access Memory (FRAM) technology. FRAM offers the benefits of both RAM and flash memory, combining non-volatile characteristics with high-speed read and write operations.
2. High-Speed SPI Interface: The FM25C640UEM8 interfaces with a host microcontroller using the Serial Peripheral Interface (SPI) protocol. It supports SPI clock frequencies of up to 20MHz, enabling fast data transfer rates.
3. Large Memory Capacity: With a storage capacity of 64Kbits, the FM25C640UEM8 can store up to 8,192 bytes of data. This makes it suitable for applications that require significant data storage.
4. Low Power Consumption: The FM25C640UEM8 is designed to operate with low power consumption, making it suitable for battery-powered devices or applications demanding energy efficiency.
5. Unlimited Write Endurance: One of the notable advantages of FRAM technology is its unlimited write endurance
