Frequently Asked Questions
What is the storage capacity and interface of the 24LC512-I/SN?
The 24LC512-I/SN provides 512Kbits of non-volatile storage organized as 65,536 bytes (64K x 8-bit). It uses the I2C serial interface with a control byte of 1010DDDR, supporting up to 400kHz fast-mode operation. Up to eight devices can be addressed on the same bus using the three hardware address pins.
What are the endurance and data retention specifications of the 24LC512?
The 24LC512-I/SN is rated for a minimum of 1,000,000 write/erase cycles per memory cell and guarantees a minimum data retention time of 200 years. These specifications make it highly reliable for applications where configuration data or calibration values must persist over the product's full lifetime without corruption.
What package does the 24LC512-I/SN use and is it lead-free?
The 24LC512-I/SN is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, JEDEC code R-PDSO-G8. The device is fully RoHS and Pb-free compliant (JESD-609 code e3), making it appropriate for environmentally regulated consumer, industrial, and automotive end products that must meet global hazardous materials directives.
What applications is the 24LC512-I/SN commonly used in?
The 24LC512-I/SN is widely used in data loggers, smart meters, industrial PLCs, medical instruments, and consumer electronics for storing configuration tables, event logs, firmware parameters, and user preferences. Its 512Kbit capacity provides enough space to store extensive records or lookup tables, while the I2C interface keeps wiring simple with just two signal lines.
