FAQs

Q: What is the difference between Serial EEPROM and Parallel EEPROM?

A: Serial EEPROM uses a single serial data line for communication, while Parallel EEPROM uses multiple parallel data lines. Serial EEPROM offers higher speeds, lower power consumption, and smaller size compared to Parallel EEPROM.

Q: Can the M24C32-FMC6TG be used for code storage?

A: Yes, M24C32-FMC6TG is suitable for storing firmware code and configuration data. However, it is important to consider the write endurance and data retention requirements of your application.

Q: What is the purpose of the Write Protect Pin (WP)?

A: The WP pin allows you to protect the memory from accidental write operations. When asserted, the memory is protected from writes, ensuring data integrity.

Q: How can I increase the write endurance of the M24C32-FMC6TG?

A: To extend the endurance of the memory, minimize write operations and avoid overwriting the same memory locations frequently. Using wear-leveling algorithms can also help distribute writes evenly across the memory cells.
