Frequently Asked Questions
How much data can 24AA02-I/SN store and how is it organized?
24AA02-I/SN provides 2Kbit of EEPROM storage organized as 256 bytes accessible via I2C. The memory is byte-addressable, and most implementations support page-write operations of up to 8 bytes per write cycle, reducing bus transaction overhead when writing blocks of configuration or calibration data.
Which supply voltage range is compatible with 24AA02-I/SN?
24AA02-I/SN operates across a supply range of 1.7V to 5.5V, covering 1.8V, 2.5V, 3.3V, and 5V logic families. This wide 1.7V to 5.5V tolerance eliminates the need for level shifting in mixed-voltage systems and makes the device suitable for low-power battery-operated designs.
For a space-constrained IoT gateway design, does the SOIC-8 package allow high-density placement?
The SOIC-8 package has a body size of approximately 5.0mm x 4.4mm with 1.27mm lead pitch, which is suitable for moderately dense layouts. For tighter board space, a smaller alternative such as the 24AA02 in an SOT-23-5 or DFN package may be more appropriate, reducing area to around 3.0mm x 1.75mm.
What is the endurance rating and data retention for 24AA02-I/SN?
The 24AA02 family is specified for a minimum of 1,000,000 erase-write cycles per byte and 200-year data retention at typical conditions. These 1M-cycle endurance and 200-year retention figures make it reliable for frequently updated configuration registers and logging in embedded equipment.
