Frequently Asked Questions
What is the memory size and organization of the 24AA024H-I/SN?
The 24AA024H-I/SN is a 2Kbit EEPROM organized as 256 words by 8 bits (256 x 8). This provides 256 bytes of non-volatile storage, which is sufficient for configuration data, calibration coefficients, and small data tables in embedded systems.
What is the minimum operating voltage for the 24AA024H-I/SN and why is it important?
The 24AA024H-I/SN operates from as low as 1.7V, indicated by the 'AA' family designation and 'H' suffix for high-voltage compatibility. This low-voltage operation is critical for battery-powered devices using single-cell LiPo batteries or energy harvesting systems that operate near 1.8V.
How many 24AA024H-I/SN devices can be connected to a single I2C bus?
Up to 8 units of the 24AA024H-I/SN can be connected to a single I2C bus simultaneously. The device uses three hardware address pins (A0, A1, A2) that can be tied high or low to assign unique I2C addresses, allowing multiple EEPROMs on the same bus.
What package does the 24AA024H-I/SN use?
The 24AA024H-I/SN comes in an 8-pin SOIC package (SOIC-8, JESD-30 code R-PDSO-G8). This industry-standard surface-mount package is compact, widely supported by PCB layout tools, and compatible with automated assembly processes.
What are the endurance and data retention specifications for the 24AA024H-I/SN?
The 24AA024H-I/SN is rated for 1 million write/erase cycles per memory location with a minimum data retention of 200 years. These specifications make it suitable for applications requiring frequent data updates over the product lifetime while maintaining reliable long-term data integrity.
