Frequently Asked Questions
What is the storage capacity and interface of the 24AA64-I/MS?
The 24AA64-I/MS is a 64-Kbit (8 KB) EEPROM that communicates via the I2C serial interface at clock frequencies up to 400 kHz. The I2C control byte is 1010DDDR, allowing up to 8 devices to share the same bus by setting the three device-address bits differently.
What is the write endurance and data retention of the 24AA64-I/MS?
This EEPROM is rated for a minimum of 1,000,000 write/erase cycles per byte, ensuring reliable operation even in applications with frequent updates. Data retention is guaranteed for a minimum of 200 years under normal storage conditions, making it suitable for archiving calibration or configuration data.
What package does the 24AA64-I/MS use?
The 24AA64-I/MS is housed in an 8-pin MSOP package (Microchip code MSOP-8, JESD-30 code S-PDSO-G8). This compact surface-mount package is ideal for space-constrained designs such as wearables, sensor modules, and portable industrial equipment where PCB area is at a premium.
Is the 24AA64-I/MS RoHS compliant and what is its availability lead time?
Yes, the 24AA64-I/MS carries a Pb-free designation (JESD-609 code e3) and is RoHS compliant. Factory lead time is approximately 23 weeks for standard orders. For time-sensitive projects, checking authorized distributor stock is recommended to find parts available for immediate shipment.
What are typical applications for the 24AA64-I/MS EEPROM?
This device is commonly used to store non-volatile configuration settings, calibration tables, user preferences, and firmware parameters in microcontroller-based systems. Typical applications include smart meters, medical devices, industrial sensors, automotive body electronics, and consumer IoT products where data must be retained across power cycles without a battery backup.
