Key Features
- 1.8V low-voltage I2C interface compatible with modern low-power microcontrollers and SoCs, eliminating the need for level-translation circuitry
- Multiple device addressing via I2C control byte (1010XMMR) allowing up to four 24AA08 devices on a single bus for up to 32Kbit total storage
- TSSOP-8 package with 1,000,000 write/erase cycle endurance and 200-year data retention for reliable long-life embedded applications
Applications
The 24AA08-I/ST is ideal for storing configuration data, calibration constants, and user preferences in low-power embedded systems such as IoT sensor nodes, portable medical devices, and smart home appliances. Its 1.8V I2C interface integrates directly with modern low-voltage microcontrollers and application processors without level-shifting hardware. The device is also widely deployed in industrial instrumentation and consumer electronics for non-volatile storage of operating parameters and device identity information.

Frequently Asked Questions
What is the memory size and organization of the 24AA08-I/ST?
The 24AA08-I/ST provides 8Kbit (8,192 bits) of EEPROM storage organized as 1,024 bytes (1024x8). This byte-addressable organization suits firmware that stores structured configuration records, serial numbers, or sensor calibration tables requiring byte-level granularity in embedded system designs.
What interface and bus speed does the 24AA08-I/ST support?
The 24AA08-I/ST uses the standard 2-wire I2C serial interface with a maximum clock frequency of 100kHz (Standard Mode). It uses the I2C control byte format 1010XMMR, where the MM bits select the memory bank, allowing up to four 24AA08 devices to share a single I2C bus for a combined capacity of 32Kbit.
What supply voltage does the 24AA08-I/ST require?
The 24AA08-I/ST operates starting from 1.8V, making it directly compatible with low-voltage microcontrollers, SoCs, and FPGAs that use 1.8V or 2.5V I/O standards. This eliminates the need for external level-shifting components and reduces system complexity and power consumption in battery-operated designs.
What is the endurance and data retention of the 24AA08-I/ST?
The 24AA08-I/ST is rated for a minimum of 1,000,000 write/erase cycles per byte and provides a minimum data retention of 200 years. These specifications ensure the device remains reliable throughout the product's entire service life, even in applications that update stored data frequently.
What package does the 24AA08-I/ST come in and is it RoHS compliant?
The 24AA08-I/ST comes in a TSSOP-8 (Thin Shrink Small Outline Package with 8 pins) surface-mount package with 0.65mm pin pitch, offering a smaller footprint than standard SOIC-8 devices. It is fully RoHS compliant and lead-free, meeting global environmental regulations for consumer, industrial, and automotive applications.
