Frequently Asked Questions
What is the storage capacity and endurance rating of the 24LC512-I/P EEPROM?
The 24LC512-I/P provides 512 Kbits (64 KB) of non-volatile EEPROM storage and is rated for 1,000,000 write/erase cycles per byte location. This high endurance makes it suitable for applications that frequently update configuration registers, log sensor data, or store firmware parameters without wearing out the memory over the product lifetime.
How many 24LC512-I/P devices can be connected to a single I2C bus, and what I2C clock speed does it support?
Up to 8 devices of the 24LC512-I/P can be placed on a single I2C bus simultaneously by configuring the 3 hardware address pins (A0, A1, A2), providing up to 512 KB of total addressable EEPROM. The device supports a maximum I2C clock frequency of 400 kHz in Fast Mode, enabling efficient sequential data access from a microcontroller.
For a data logging application with infrequent reads but frequent small writes, how long will 24LC512-I/P data persist without power?
The 24LC512-I/P guarantees a minimum data retention time of 200 years under standard operating conditions, making it well-suited for long-term logging of configuration snapshots, calibration constants, and fault records. This retention figure assumes the device is stored within the rated temperature range and data was written correctly within the 1,000,000-cycle endurance limit.
