MT28F320J3FS-11 MET

Memory IC Overview

The MT28F320J3FS-11 MET is a nonvolatile, electrically block-erasable Flash memory device with a capacity of 32Mbit. It supports x8 and x16 data organization modes via the BYTE# pin. The device features asynchronous page mode reads with an access time of 110ns. It operates within a voltage range of 2.7V to 3.6V for both VCC and VCCQ. The component is housed in a 64-ball FBGA package with a 1.00mm pitch 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
• Features in-system block locking and flexible sector protection mechanisms
• Includes automatic suspend options for block erase and program operations
• Provides enhanced data protection through VPEN control during power transitions

Memory IC Applications

• Embedded systems requiring code storage
• Data storage applications needing block erasability
• Industrial control systems operating in extended temperature ranges

Memory IC Procurement Notes

Verify the specific ordering suffixes against Micron's official part marking decoder to ensure correct package type and manufacturer identification code. Confirm that the FS suffix corresponds to the standard 64-ball FBGA package and that the ET suffix matches the required extended temperature rating. Cross-reference the abbreviated device mark with the manufacturer's database to validate authenticity and specifications before procurement.

Memory IC Selection Notes

Select this component when a 32Mbit parallel NOR Flash memory with 110ns access speed is required. Ensure the design accommodates the 64-ball FBGA footprint and the 2.7V to 3.6V supply voltage constraints. Consider the availability of the Scalable Command Set if software driver simplicity across different Flash families is a priority. Verify that the system supports the necessary command sequences for block locking and programming operations.

Memory IC Part Context

This device belongs to the Micron Q-Flash family, which includes the MT28F128J3 and MT28F640J3 variants. These devices share similar architectural features, including CFI support and even-sector organization. The MT28F320J3 specifically utilizes 0.18µm process technology, distinguishing it from the 0.15µm technology used in the larger capacity counterparts within the same series.

Memory IC Replacement Considerations

Consult Micron's official documentation for verified substitute part numbers. Ensure any replacement maintains compatibility with the Scalable Command Set and CFI standards. Verify that the alternative device supports the same x8/x16 organization and meets the required 110ns access time specification.
