MX25L3273EM2I-10G

Memory IC Overview

The MX25L3273EM2I-10G is a 32M-bit CMOS Serial Multi I/O (MXSMIO) Flash memory manufactured by Macronix. It features a 3-wire SPI interface compatible with Mode 0 and Mode 3, supporting read speeds up to 104MHz in Fast Read mode with 8 dummy cycles. The device operates on a single 2.7V to 3.6V power supply and includes a permanent fixed QE bit enabling Quad I/O mode. It offers 1024 equal sectors of 4K bytes each and supports various block erase sizes.

Memory IC Feature Summary

• Supports multi-I/O operations including Dual and Quad I/O modes for enhanced sequential read performance
• Includes advanced security features such as flexible individual block protection and a secured One-Time Programmable area
• Features auto erase and auto program algorithms that automatically verify data during write and erase cycles
• Provides hardware protection against inadvertent writes during power transitions through command length checking and Write Enable Latch requirements

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Industrial control applications needing robust data retention
• Consumer electronics utilizing serial flash for firmware storage

Memory IC Procurement Notes

Verify the specific package variant required, as the MX25L3273E series is available in multiple packages including 8-pin SOP, 8-pin VSOP, 16-pin SOP, and 8-WSON. Confirm that the ordering suffix matches the desired physical footprint and lead time specifications provided by the manufacturer or distributor.

Memory IC Selection Notes

Select this component when a 32M-bit capacity is required with high-speed Quad I/O read capabilities. Ensure the system design accommodates the 2.7V to 3.6V operating voltage range. Consider the permanent QE bit setting if Quad I/O functionality is essential for the application's performance requirements.

Memory IC Part Context

This part belongs to the MX25L3273E family of high-performance serial Flash memories. The 'M2I' suffix typically denotes a specific package type within the Macronix lineup, often corresponding to the 8-pin SOP configuration. The '10G' suffix indicates the speed grade and compliance status.

Memory IC Replacement Considerations

Direct replacements must match the 32M-bit capacity, SPI interface, and 2.7V-3.6V voltage range. Verify pin compatibility and software command set adherence before substitution.
