Frequently Asked Questions
What is the operating voltage range and maximum clock frequency of the 24AA01-I/SN?
The 24AA01-I/SN operates from 1.8V to 5.5V supply voltage and supports I2C clock speeds up to 400 kHz in fast mode, making it compatible with a wide range of microcontrollers and 3.3V or 5V systems.
How many 24AA01-I/SN devices can be connected to a single I2C bus?
Up to 8 devices of the 24AA01-I/SN can be connected on the same I2C bus simultaneously. Each device uses 3 hardware address pins (A0, A1, A2) to select a unique 7-bit address, enabling up to 8 independent 1Kbit EEPROM nodes on 2-wire I2C.
In which compact designs is the 24AA01-I/SN SOIC-8 package most suitable compared to DIP alternatives?
The SOIC-8 package of 24AA01-I/SN is preferred in space-constrained PCB designs due to its smaller footprint versus 8-pin DIP. It fits easily on SMT production lines, supports industrial temperature -40°C to +85°C, and occupies roughly 50% less board area than a through-hole DIP-8 package.
