MX29GL128FLXGI-70G

Memory IC Overview

The MX29GL128FLXGI-70G is a 128 Mbit (16M x 8 or 8M x 16) NOR flash memory manufactured by Macronix. It operates on a single 2.7 V to 3.6 V power supply and features an asynchronous parallel interface with a maximum access time of 70 ns. The device utilizes a 64 KB uniform sector architecture comprising 128 equal sectors, supplemented by an extra 128-word security sector. It supports both byte and word modes via the BYTE# pin and includes a 64-byte write buffer for accelerated programming.

Memory IC Feature Summary

• Supports 64-byte write buffer programming to accelerate data writing operations
• Features advanced sector protection including solid and password protection methods
• Includes a dedicated 128-word security sector that can be factory locked or customer lockable
• Provides hardware write protect capability through the WP#/ACC input pin

Memory IC Applications

• Storage of boot code in embedded systems requiring fast random access
• Code execution in place (XIP) applications within microcontroller environments
• Data storage for configuration parameters and firmware updates
• Industrial control systems requiring robust sector protection mechanisms

Memory IC Procurement Notes

Verify the specific package variant against the ordering information section of the datasheet, as the MX29GL128F series is available in multiple packages including TSOP, FBGA, and LFBGA. Confirm that the VI/O voltage requirements align with the system design, particularly noting distinctions between H/L and U/D speed grades regarding I/O voltage compatibility with VCC.

Memory IC Selection Notes

Select this component when a 128 Mbit capacity with a 70 ns access time is required for parallel NOR applications. Ensure the design accommodates the 2.7 V to 3.6 V operating range and utilizes the appropriate sector protection features if data integrity is critical. Consider the write buffer functionality if programming speed is a primary performance constraint.

Memory IC Part Context

This part belongs to the MX29GL128F family of single-voltage 3V NOR flash memories from Macronix. The family shares common software commands and block structures but varies in speed grades, package types, and I/O voltage specifications. The 'L' suffix typically denotes lower speed variants, while 'H' indicates higher performance options within the same density class.
