Frequently Asked Questions
What is the memory capacity and organization of the 11AA010T-I/TT?
The 11AA010T-I/TT is a 1Kbit EEPROM organized as 128 bytes (128x8 bits), providing byte-addressable non-volatile storage. This byte-wide organization is convenient for storing ASCII strings, configuration bytes, and calibration data in embedded microcontroller applications.
What interface does the 11AA010T-I/TT use and how fast is it?
The 11AA010T-I/TT uses Microchip's UNI/O single-wire serial interface, which requires only one I/O pin for bidirectional communication at up to 1MHz. This minimizes the number of GPIOs needed from the host microcontroller, making it ideal for pin-constrained applications such as wearables and compact IoT nodes.
What supply voltage does the 11AA010T-I/TT require?
The 11AA010T-I/TT is designed for 1.8V operation, making it compatible with modern low-voltage microcontrollers and SoCs commonly used in portable and IoT applications. This low operating voltage also reduces power consumption, which is critical for battery-powered devices requiring long battery life.
What package does the 11AA010T-I/TT use and how small is it?
The 11AA010T-I/TT is housed in a 3-pin SOT-23 surface-mount package (JESD-30 R-PDSO-G3, Microchip code SOT-23-3), one of the smallest standard IC packages available, making it ideal for ultra-miniature designs in wearables, medical patches, and compact consumer electronics where PCB space is extremely limited.
What are the data retention and endurance characteristics of the 11AA010T-I/TT?
The 11AA010T-I/TT guarantees a minimum data retention period of 200 years and supports up to 1 million write/erase cycles, ensuring that stored configuration data, calibration values, and device IDs remain intact throughout the entire product lifetime even in applications with frequent data updates.
