Frequently Asked Questions
How many write cycles can the 24LC65-I/SM endure, and what is its data retention time?
The 24LC65-I/SM is rated for 1,000,000 erase/write cycles per byte location, making it suitable for high-endurance logging applications. Data retention is specified at a minimum of 200 years under normal operating conditions, ensuring long-term reliable storage for configuration and calibration data.
What supply voltage range does the 24LC65-I/SM support, and what I2C clock speed can it handle?
The 24LC65-I/SM operates from 2.5V to 5.5V, making it compatible with both 3.3V and 5V microcontroller systems. It supports I2C clock frequencies up to 400 kHz (Fast Mode), enabling efficient read/write transactions in time-sensitive embedded applications.
Which embedded system designs benefit most from using the 24LC65-I/SM EEPROM?
Designs that need compact non-volatile storage of configuration registers, calibration tables, or user preferences benefit greatly from the 24LC65-I/SM. Its 64-Kbit capacity, I2C 2-wire interface, and -40°C to +85°C industrial temperature range make it a strong fit for industrial controllers, IoT sensor nodes, and medical monitoring equipment.
How does the 24LC65 compare to smaller Microchip EEPROMs in terms of capacity and page size?
The 24LC65 offers 64 Kbits (8 KB) of storage, which is 4x more than the 24LC16 (16 Kbits). Its 8-byte page write buffer allows burst writes across multiple consecutive addresses, reducing I2C transaction overhead compared to byte-write-only devices. This makes it preferable when storing larger data blocks such as firmware parameters or lookup tables.
