Frequently Asked Questions
How many write cycles can the 24LC65/SM endure before memory wear-out?
The 24LC65/SM is rated for up to 1,000,000 write/erase cycles per byte, making it suitable for applications that perform frequent configuration updates or log small amounts of data. Data retention after cycling is guaranteed for a minimum of 200 years under normal operating conditions.
What I2C clock speed does the 24LC65/SM support, and how does this affect system design?
The 24LC65/SM supports a maximum I2C clock frequency of 100 kHz (standard mode). This is adequate for most embedded microcontroller applications writing calibration or configuration data, and the 2-wire interface minimizes the number of GPIO pins needed from the host device.
In which embedded applications is the 24LC65/SM most commonly deployed?
The 24LC65/SM is frequently used in smart metering, industrial sensors, medical equipment, and automotive modules that require 64 Kbit of non-volatile storage. Its 8-pin SOIJ package suits space-constrained PCB designs, while the hardware write-protect pin prevents accidental overwrite in safety-critical deployments.
