Frequently Asked Questions
How many write/erase cycles does 25AA160B-I/SN support before endurance degradation becomes a concern?
25AA160B-I/SN is rated for 1,000,000 write/erase cycles per memory location. For applications that update the same byte every second, wear-leveling or address rotation techniques should be applied to distribute writes evenly across the 2 KB address space.
At what SPI clock frequency can 25AA160B-I/SN transfer data, and how does that affect read throughput?
25AA160B-I/SN supports SPI clock frequencies up to 10 MHz, allowing sequential page reads at up to 1.25 MB/s in theory. In practice, instruction overhead and CS assertion timing mean effective throughput is lower, but 10 MHz SPI is more than adequate for reading a 2 KB configuration page in under 2 ms.
Can 25AA160B-I/SN reliably retain data for multi-year deployments in industrial sensor nodes?
Yes. Microchip specifies a minimum data retention of 200 years for 25AA160B-I/SN under standard operating conditions, making it suitable for long-life industrial deployments. Even after 1,000,000 write cycles, data retention remains valid for the rated period on cells that have not been worn beyond the endurance limit.
Is the SOIC-8 package of 25AA160B-I/SN compatible with standard footprints used by competing SPI EEPROM vendors?
Yes. 25AA160B-I/SN uses the industry-standard 8-pin SOIC footprint with JEDEC MS-012 dimensions, pin-compatible with many SPI EEPROMs from Atmel (AT25160B) and similar families. This allows drop-in replacement sourcing and dual-source supply qualification without PCB redesign.
