Frequently Asked Questions
What is the I2C bus speed and supply voltage range for the 24LC02B-I/SNG?
The 24LC02B-I/SNG supports I2C fast-mode operation at up to 400 kHz and operates from a supply voltage of 2.5 V to 5.5 V. This flexibility makes it directly compatible with both 3.3 V ARM microcontrollers and 5 V AVR or PIC platforms without additional level shifters.
How many write cycles can the 24LC02B-I/SNG handle and how long does it retain data?
The 24LC02B-I/SNG endures a minimum of 1,000,000 write/erase cycles per byte location with a data retention time exceeding 200 years. This high endurance and long retention period make it reliable for storing configuration settings or calibration data that may be updated frequently over the product lifetime.
How can multiple 24LC02B-I/SNG devices share a single I2C bus in a sensor network?
The 24LC02B-I/SNG uses the I2C control byte 1010XXXR, where address pins A0-A2 set the lower 3 bits, allowing up to 8 devices on a single 2-wire I2C bus. Each device can store its own 256-byte configuration block, providing up to 2 Kbytes of addressable EEPROM on 2 wires without adding extra GPIO or chip-select lines.
