MX29GL512FHT2I-10Q

Memory IC Overview

The MX29GL512FHT2I-10Q is a 512 Mbit parallel NOR flash memory manufactured by Macronix. It operates on a single 2.7 V to 3.6 V power supply and supports both byte (x8) and word (x16) data modes via the BYTE# pin. The device features a uniform sector architecture with 512 equal sectors of 64 Kwords each. Key performance specifications include a maximum access time of 100 ns, page access times of 25 ns, and fast program/erase speeds. It includes hardware write protection, sector lock status verification, and Ready/Busy output.

Memory IC Feature Summary

• Supports switchable Byte/Word mode for flexible data bus interfacing
• Features advanced sector protection including solid and password protection capabilities
• Includes a dedicated extra 128-word security sector that is factory locked and customer lockable
• Provides hardware reset and Ready/Busy output for efficient operation monitoring

Memory IC Applications

• Code storage in embedded systems requiring direct execution
• BIOS and firmware storage in industrial control equipment
• Data logging applications utilizing sector erase and resume functions
• Consumer electronics requiring high reliability and low power consumption

Memory IC Procurement Notes

Verify the specific suffix 'H' indicates the 100 ns speed grade and 'T2I' denotes the 56-pin TSOP package configuration. Confirm the 'Q' suffix aligns with RoHS compliance requirements. Ensure the ordering information matches the exact voltage range and interface timing specified in the official datasheet to avoid compatibility issues with host controllers.

Memory IC Selection Notes

Select this component when a single-voltage 3V NOR flash with uniform sector architecture is required. It is suitable for designs needing hardware write protection and accelerated programming capabilities. Consider the 56-pin TSOP package for surface mount applications where space constraints allow. Verify that the system supports the necessary command sequences for sector protection and buffer programming operations.

Memory IC Part Context

This part belongs to the MX29GL512F series of single voltage 3V only flash memories. It shares architectural similarities with other devices in the family but differs in speed grades and package options. The series is designed for applications requiring high endurance and long data retention. It is compatible with JEDEC standards for pinout and software interfaces.

Memory IC FAQ

How does the WP#/ACC pin function?

The WP#/ACC pin serves as a hardware write protect input when driven LOW, protecting the highest or lowest sector. When driven HIGH, it allows normal operation. Applying high voltage to this pin enables accelerated programming mode.

What is the purpose of the security sector?

The device includes an extra 128-word sector for security purposes. This sector is factory locked and identifiable, and can be further locked by the customer to prevent unauthorized modification.
