Frequently Asked Questions
What is the memory capacity of the 11AA010-I/SN?
The 11AA010-I/SN provides 1 Kbit (128 bytes) of EEPROM storage, which is sufficient for storing device configuration parameters, factory calibration data, serial numbers, and small lookup tables in microcontroller-based embedded designs.
How does the single-wire UNI/O interface of the 11AA010-I/SN work?
The UNI/O interface uses a single bi-directional data line shared between the host and the EEPROM, communicating at up to 1 MHz using a Manchester-encoded protocol. This reduces the required microcontroller I/O pins to just one, which is beneficial in pin-constrained designs such as small sensor nodes and wearable devices.
What is the write/erase endurance of the 11AA010-I/SN?
The 11AA010-I/SN is rated for a minimum of 1,000,000 write/erase cycles per byte location, making it suitable for applications that frequently update stored values such as event counters, adaptive calibration registers, and rolling log buffers without concern for premature memory wear-out.
What package does the 11AA010-I/SN use and what is its footprint?
The 11AA010-I/SN is available in an 8-pin SOIC (SOIC-8 / R-PDSO-G8) surface-mount package with standard 1.27 mm pin pitch, which is compatible with common SMD PCB footprints and supports both reflow and wave soldering assembly processes.
How long can the 11AA010-I/SN retain stored data without power?
The 11AA010-I/SN guarantees a minimum data retention time of 200 years at room temperature, ensuring that stored configuration, calibration, and identification data remains valid well beyond the expected service life of virtually any embedded product in which it is used.
