MT28F128J3FS-12 MET TR

Memory IC Overview

The MT28F128J3FS-12 MET TR is a 128Mb Q-Flash NOR memory device manufactured by Micron Technology. It features an asynchronous interface with 120ns read access time and supports x8/x16 data bus widths. The device operates within a voltage range of 2.7V to 3.6V for both VCC and VPEN. It utilizes a 56-pin TSOP Type I package and is rated for extended operating temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports Common Flash Interface (CFI) and Scalable Command Set (SCS) for software compatibility
• Includes in-system block locking and flexible sector protection mechanisms
• Features automatic suspend options for block erase and program operations
• Provides enhanced data protection via the VPEN pin configuration

Memory IC Applications

• Embedded systems requiring nonvolatile code storage
• Industrial control applications needing extended temperature operation
• Consumer electronics utilizing standard parallel flash interfaces

Memory IC Procurement Notes

Verify the specific ordering suffixes against official Micron documentation to confirm package type, lead-free status, and manufacturer identification code. Ensure the requested part matches the exact density and timing specifications required for your design. Contact the factory or authorized distributors to confirm current availability and lifecycle status.

Memory IC Selection Notes

Select this component when a 128Mb capacity with 120ns access speed is required. The 56-pin TSOP package suits designs with space constraints for surface-mount technology. Consider the extended temperature range if the application operates in harsh environments. Verify compatibility with existing host controllers supporting CFI and SCS protocols.

Memory IC Part Context

This device belongs to the Micron MT28F J3 series of Q-Flash memories. It shares architectural similarities with the MT28F640J3 and MT28F320J3 models but offers higher density. The series is designed for high-reliability applications requiring robust data protection and fast random access capabilities.

Memory IC Replacement Considerations

Consult Micron's official cross-reference tools for verified substitutes. Ensure any replacement maintains identical pinout, voltage requirements, and command set compatibility.
