Frequently Asked Questions
How many write cycles can the 25LC320A-I/P endure before data retention becomes unreliable?
The 25LC320A-I/P is rated for 1,000,000 write/erase cycles per cell, making it suitable for moderately write-intensive applications. Combined with a minimum 200-year data retention specification, this ensures long-term reliability for configuration and calibration storage in industrial and consumer designs.
Can 25LC320A-I/P operate reliably in a 2.5 V embedded system at full SPI speed?
At 2.5 V supply, the 25LC320A-I/P supports SPI clock frequencies up to 5 MHz, which meets the throughput needs of most microcontroller-based logging or configuration systems. The device extends its full 10 MHz clock rate at higher supply voltages up to 5.5 V for faster data transfer.
What lead time and packaging should buyers plan for when ordering 25LC320A-I/P in volume?
The 25LC320A-I/P carries a factory lead time of approximately 14 weeks, so procurement teams should build buffer stock for production runs. The part ships in an 8-pin PDIP package (PDIP-8), which is through-hole and well-suited for prototype boards or panel-mount assemblies with DIP sockets.
Is 25LC320A-I/P RoHS compliant and what is the Pb-free status for export documentation?
Yes, the 25LC320A-I/P is fully Pb-free and RoHS-compliant, confirmed by its JESD-609 Code e3 classification. Procurement and compliance teams can reference this code for export declarations, material declarations, and restricted substance reports without requiring additional supplier documentation.
