Key Features
- I2C interface with 1010XMMR control byte supporting multiple devices on a shared two-wire bus
- 1.8V minimum supply voltage enabling integration with ultra-low-voltage microcontrollers and SoCs
- 1,000,000 write/erase cycle endurance with 200-year data retention for long-life embedded applications
- Ultra-compact MSOP-8 package reducing PCB footprint versus standard SOIC-8 for space-constrained designs
Applications
The 24AA08-I/MS is commonly used in microcontroller systems, smart sensors, and portable devices that require I2C-based non-volatile storage for configuration data, user preferences, and calibration tables. Its 1.8V operation and MSOP-8 package make it ideal for wearable electronics, IoT sensor nodes, and compact handheld instruments. The I2C bus compatibility allows multiple EEPROMs to share the same two-wire bus, simplifying multi-device storage architectures.

Frequently Asked Questions
What communication interface does the 24AA08-I/MS use and what is its maximum clock speed?
The 24AA08-I/MS uses an I2C serial interface with a maximum clock frequency of 100kHz (standard mode). It uses the control byte pattern 1010XMMR, where X and MM bits select the memory bank and the R bit selects read or write operations.
What is the storage capacity and data retention of the 24AA08-I/MS?
The 24AA08-I/MS provides 8Kbit (1,024 bytes) of EEPROM storage and supports 1,000,000 write/erase cycles with a minimum data retention of 200 years. This makes it suitable for applications that require frequent updates to stored configuration data over a long product lifetime.
What package does the 24AA08-I/MS use and is it RoHS compliant?
The 24AA08-I/MS is packaged in an MSOP-8 (Mini Small Outline Package, 8-pin, JESD-30 code S-PDSO-G8), which is smaller than a standard SOIC-8. It is fully RoHS-compliant with Pb-free construction (JESD-609 code e3). Factory lead time is approximately 11 weeks.
How does the 24AA08-I/MS differ from 25-series SPI EEPROMs of the same capacity?
Unlike 25AA08-series SPI EEPROMs that use a 4-wire SPI interface, the 24AA08-I/MS uses a 2-wire I2C bus, requiring only SDA and SCL lines. This reduces pin count and allows up to eight devices to share the same bus using address bits, simplifying wiring in multi-node sensor networks and multi-memory embedded systems.
