Frequently Asked Questions
What is the storage capacity and organization of the 24AA512-I/ST?
The 24AA512-I/ST provides 512Kbits of non-volatile EEPROM storage organized as 64K x 8 bits, giving 65,536 bytes of addressable memory. This capacity is suitable for storing firmware parameters, calibration data, and large configuration tables in embedded systems.
What supply voltage range does the 24AA512-I/ST support?
The 24AA512-I/ST operates at a nominal 1.8V supply, making it compatible with modern low-voltage microcontrollers and SoCs. This low operating voltage helps reduce overall system power consumption, which is especially beneficial in battery-powered IoT and portable applications.
How many devices can be connected to a single I2C bus using the 24AA512-I/ST?
Up to eight 24AA512-I/ST devices can be connected on a single I2C bus by configuring the three hardware address pins (A0, A1, A2), providing up to 4Mbit of total addressable memory. This flexibility supports scalable storage architectures without additional bus infrastructure.
What package does the 24AA512-I/ST come in and is it RoHS compliant?
The 24AA512-I/ST is available in an 8-pin TSSOP (Thin Shrink Small Outline Package) surface-mount package, which is compact and easy to hand-solder or reflow. It is fully RoHS compliant (Pb-free, JESD-609 code e3), meeting environmental regulations for lead-free manufacturing.
