Frequently Asked Questions
How many write/erase cycles does 93AA46-I/SN support, and what does this mean for applications with frequent data updates?
93AA46-I/SN is rated for 1,000,000 write/erase cycles per cell, providing ample endurance for most embedded applications. For a device that writes configuration data once per hour, this endurance supports over 100 years of continuous operation. High-cycle-rate applications such as logging sensor readings every minute would approach the endurance limit after approximately 2 years, suggesting wear-leveling or external flash for very high-frequency writes.
What serial interface and clock speed does 93AA46-I/SN use for communication with a microcontroller?
93AA46-I/SN uses a 3-wire SPI-compatible serial interface with a maximum clock frequency of 2 MHz. The 8-bit word organization (128 bytes total) allows byte-level read and write operations, making it straightforward to integrate with any microcontroller SPI peripheral running at 1 MHz to 2 MHz. The simple protocol minimizes firmware complexity for storing and retrieving calibration or configuration data.
What is the minimum supply voltage for 93AA46-I/SN and which battery configurations support it?
93AA46-I/SN operates at a supply voltage as low as 1.8 V, which is directly compatible with 2-cell AA alkaline batteries (nominal 3.0 V dropping toward 2.0 V at end of life), CR2032 coin cells (3 V), and low-voltage LDO regulators outputting 1.8 V. This makes it ideal for long-life IoT nodes, remote sensors, and portable instruments where minimizing supply voltage extends battery runtime.
