MT28F640J3FS-115 MET

The MT28F640J3FS-115 MET is a 64 Mbit parallel flash memory device in a 64-ball FBGA (10×13) package. It implements non-volatile FLASH architecture with industry-standard pinout and TTL-compatible I/O for system integration.

Designed for systems that require parallel NOR-style flash storage, the device provides block-level erase architecture, fast read access timing, and multiple protection features for embedded and industrial applications that operate across a wide supply and temperature range.

Key Features

• Memory Core  64 Mbit FLASH organized as 8M × 8 or 4M × 16 with sixty-four 128 KB erase blocks (64 Mb device).
• Performance  Asynchronous page-mode read access times listed as 115 ns / 25 ns (64 Mb option); industry-standard pinout and TTL-compatible inputs/outputs support common system interfaces.
• Power  VCC and programming operation support from 2.7 V to 3.6 V, enabling single-supply 3.0 V system designs.
• Package & Mounting  64-ball FBGA package (10×13) for compact board footprint and BGA mounting.
• Reliability & Endurance  Specified for 100,000 erase cycles per block and includes automatic write/erase algorithms to manage programming operations.
• Protection & Security  128-bit protection register, 64-bit unique device identifier, 64-bit user-programmable OTP cells, flexible sector locking, and enhanced data protection feature with VPEN = VSS.
• Programming & Suspend Features  Write-buffer programming with a 5.6 μs-per-byte effective programming time and automatic suspend options (Block Erase Suspend-to-Read, Block Erase Suspend-to-Program, Program Suspend-to-Read).
• Standards & Interoperability  Common Flash Interface (CFI) and Scalable Command Set for query and command compatibility across supported systems.

Typical Applications

• Embedded code storage  Parallel Flash storage for system boot and firmware where 64 Mbit capacity and fast read access are required.
• Industrial controllers  Non-volatile program and data storage for controllers operating across -40 °C to +85 °C and 2.7–3.6 V supply conditions.
• Networking and communications equipment  Storage of system firmware and configuration data using the parallel interface and industry-standard pinout for integration.

Unique Advantages

• Parallel interface with TTL-compatible I/O: Enables straightforward integration into existing parallel bus systems without special level-shifting.
• Flexible memory organization: Choice of x8 or x16 organization (8M × 8, 4M × 16) allows designers to match device width to system data buses.
• Robust block management: 64 × 128 KB erase blocks and 100,000-cycle endurance simplify wear management and long-term data retention planning.
• Embedded protection primitives: Protection register, unique ID, OTP cells, and sector locking provide layered data and configuration security.
• Suspend and resume operations: Block erase and program suspend options allow read access during long erase/program cycles to improve system responsiveness.
• Wide supply and temperature range: 2.7 V–3.6 V operation and -40 °C to +85 °C rating support a broad set of power and environmental conditions.

Why Choose MT28F640J3FS-115 MET?
