• Code execution directly from memory (XIP)
• Data logging applications requiring high endurance
• Secure identification systems using secured OTP

Memory IC Procurement Notes

Verify the specific suffix 'M2I' confirms the 8-pin SOP (200mil) package configuration. Ensure the order specifies the '-08G' variant to confirm compliance with RoHS standards and halogen-free manufacturing requirements. Cross-reference the manufacturer part number against official datasheets to validate the exact pinout and electrical specifications before integration.

Memory IC Selection Notes

Select this component when a compact 8-pin footprint is required for 256Mb capacity. It is suitable for designs needing flexible read speeds via Dual or Quad I/O modes. Consider the 100,000 cycle endurance and 20-year data retention for long-term reliability. Verify that the system voltage aligns with the 2.7V to 3.6V operating range.

Memory IC Part Context

This part belongs to the MX25L25645G series of CMOS Serial Multi I/O Flash memories. It shares core architectural features with other variants in the family but is distinguished by its specific 8-pin SOP physical packaging. The series is designed for general-purpose non-volatile storage with high-speed serial interface capabilities.

Memory IC FAQ

How does the WP#/SIO2 pin function?

In standard SPI mode, it acts as an active-low hardware write protection pin. In Quad I/O mode, it functions as SIO2 for data input/output.

What is the purpose of the Secured OTP?

It provides a 4K-bit one-time programmable area for storing unique device identifiers, which can be locked by the factory or customer to prevent further modification.
