Frequently Asked Questions
What is the capacity and organization of the 25AA160A-I/SN?
The 25AA160A-I/SN provides 16Kbit (16,384 bits) of SPI EEPROM memory organized as 2,048 bytes (2K x 8). This capacity is suitable for storing firmware settings, device calibration data, user configuration profiles, and small data logs in embedded microcontroller applications.
What are the write endurance and data retention specifications of the 25AA160A-I/SN?
The 25AA160A-I/SN guarantees 1,000,000 write/erase cycles per byte and a minimum data retention period of 200 years. These specifications make it appropriate for applications with frequent configuration updates while ensuring that stored data remains intact throughout the product's service life.
What SPI clock frequency does the 25AA160A-I/SN support and what is its supply voltage range?
The 25AA160A-I/SN supports a maximum SPI clock frequency of 10MHz for high-speed data transfers. It operates from a supply voltage range of 1.8V to 5.5V, making it compatible with both 3.3V and 5V microcontroller systems as well as low-voltage 1.8V embedded platforms.
What are the package details and lead time for the 25AA160A-I/SN?
The 25AA160A-I/SN is packaged in a 3.90mm wide SOIC-8 (R-PDSO-G8) that is fully RoHS-compliant with Pb-free construction (JESD-609 code e3). Note that the factory lead time is approximately 17 weeks, so early procurement planning is recommended for production schedules. YTEOL of 3 suggests limited remaining production life.
