Frequently Asked Questions
How does the 11AA160-I/SN single-wire interface reduce pin count compared to I2C or SPI EEPROMs?
The 11AA160-I/SN uses Microchip's UNI/O single-wire protocol, requiring only 1 data pin versus 2 pins for I2C or 4 pins for SPI. This saves 1 to 3 GPIO lines on the host MCU, critical in tiny 8-pin microcontroller designs where every I/O pin serves a dedicated function in sensor or wearable applications.
What write endurance and data retention does the 11AA160-I/SN guarantee for logging applications?
Microchip specifies 1 million write/erase cycles endurance and a minimum 200-year data retention for the 11AA160-I/SN under normal conditions. These figures make it suitable for storing frequently updated counters, log pointers, or runtime configuration in embedded systems across the -40°C to +85°C industrial temperature range.
Which supply voltage rails can the 11AA160-I/SN interface with directly without level translation?
The device operates directly from 1.8 V to 5.5 V, covering 1.8 V, 2.5 V, 3.0 V, 3.3 V, and 5 V system rails without external level shifters. At a maximum 1 MHz clock frequency, it delivers adequate throughput for the 16 Kbit (2,048 byte) capacity in most configuration-storage use cases.
