Key Features
- 16Kbit single-wire EEPROM in a 3-pin SOT-23 package, providing the smallest possible footprint for non-volatile storage in miniaturized designs
- 1.8V operation with 1MHz single-wire interface clock, enabling integration with the lowest-voltage microcontrollers in energy-sensitive IoT applications
- 1,000,000 write/erase endurance cycles with 200-year data retention, delivering exceptional reliability for long-life embedded products
Applications
The 11AA160T-I/TT is designed for applications where PCB space is at a premium, such as wearable devices, smart labels, miniature sensors, and implantable medical electronics that need non-volatile storage accessible via a single GPIO line. Its single-wire interface reduces pin count to the absolute minimum, freeing up valuable I/O resources on small microcontrollers. The 1.8V operation and low standby current make it ideal for coin-cell and energy-harvesting powered systems requiring reliable configuration or ID storage.

Frequently Asked Questions
What interface does the 11AA160T-I/TT use and how many pins does it require?
The 11AA160T-I/TT uses a single-wire (1-Wire compatible) serial interface, requiring only one I/O pin on the host microcontroller plus power and ground, housed in a 3-pin SOT-23 package for minimal board space usage.
What is the memory capacity and minimum operating voltage of the 11AA160T-I/TT?
The 11AA160T-I/TT provides 16Kbit (2,048 x 8-bit) of EEPROM storage and operates from a minimum supply voltage of 1.8V, making it suitable for ultra-low-power embedded systems and battery-powered portable devices.
What are the endurance and data retention specifications for the 11AA160T-I/TT?
The 11AA160T-I/TT is rated for 1,000,000 write/erase cycles and guarantees a minimum data retention period of 200 years, ensuring the memory remains reliable throughout the entire operational lifetime of the end product.
What types of applications benefit from the 11AA160T-I/TT's single-wire interface?
Applications such as wearable fitness trackers, RFID accessories, smart clothing, cable and adapter identification, medical disposables, and any system with extremely limited I/O pins benefit from the single-wire interface, which requires only one signal line to access non-volatile storage.
Is the 11AA160T-I/TT RoHS compliant?
Yes, the 11AA160T-I/TT is Pb-free and RoHS compliant (JESD-609 Code e3), meeting global environmental regulations and making it suitable for use in consumer, industrial, and medical products sold in markets with strict hazardous substance restrictions.
