Frequently Asked Questions
What is the memory organization and I2C interface of the 24LC08B-I/SN?
The 24LC08B-I/SN provides 8Kbits organized as 1K x 8-bit, divided into four blocks of 256 bytes each. It uses the I2C interface with a 1010XMMR control byte format and supports up to 400kHz clock frequency, enabling straightforward multi-block addressing and compatibility with standard I2C microcontrollers.
What is the supply voltage range for the 24LC08B-I/SN?
The 24LC08B-I/SN operates from a 2.5V supply (minimum), making it compatible with a wide range of low-voltage microcontroller systems, embedded processors, and SoCs that operate on 2.5V, 3.3V, or 5V power rails with appropriate I2C level considerations.
What are the write endurance and data retention specifications of the 24LC08B-I/SN?
The 24LC08B-I/SN supports up to 1,000,000 write/erase cycles per byte with a minimum data retention exceeding 200 years, and the manufacturer specifies a minimum 100,000 erase/write cycle guarantee. This makes it reliable for applications requiring frequent data updates over long product lifetimes.
What package does the 24LC08B-I/SN use and is it RoHS compliant?
The 24LC08B-I/SN is housed in a standard SOIC-8 package (Manufacturer code: SOIC-8, JESD-30 code: R-PDSO-G8), a widely available and easy-to-solder through-hole-compatible surface-mount package. It carries JESD-609 code e3 confirming it is RoHS compliant and lead-free.
What are typical applications for the 24LC08B-I/SN?
The 24LC08B-I/SN is commonly used for storing configuration tables, calibration data, system logs, and user settings in industrial controllers, consumer appliances, smart meters, automotive accessories, and medical devices where a small-capacity I2C EEPROM with 2.5V operation and standard SOIC-8 packaging is preferred.
