MT28F128J3RG-12 MET

The MT28F128J3RG-12 MET is a 128 Mbit non-volatile Flash memory device from Micron Technology Inc. It implements Q-FLASH architecture in a parallel memory interface and supports x8 and x16 memory organizations for flexible system integration. The device targets designs that require mid-density, non-volatile storage with verified program/erase endurance and hardware protection features.

Key Features

• Memory Core and Organization 128 Mbit Flash organized as 16M × 8 or 8M × 16 with one hundred twenty-eight 128 KB erase blocks for block-level erase control.
• Read Performance Asynchronous page-mode read access time of 120 ns for the 128 Mb device (with additional 25 ns page-mode specification referenced in datasheet).
• Programming and Write Buffer Automatic write and erase algorithms with a 5.6 µs-per-byte effective programming time when using the write buffer.
• Voltage and Power VCC/VCCQ/VPEN operation and programming across a 2.7 V to 3.6 V supply range.
• Data Protection and Security 128-bit protection register, 64-bit unique device identifier, 64-bit user-programmable OTP cells, flexible sector locking, and enhanced protection with VPEN = VSS.
• Reliability Up to 100,000 erase cycles per block and automatic suspend options including Block Erase Suspend-to-Read, Block Erase Suspend-to-Program, and Program Suspend-to-Read.
• Interface and Compatibility Parallel memory interface with industry-standard pinout and TTL-compatible inputs/outputs; supports Common Flash Interface (CFI) and the Scalable Command Set for system interoperability.
• Package and Temperature 56-pin TSOP Type I package (56-TFSOP, 0.724" / 18.40 mm width) and extended operating temperature range of −40 °C to +85 °C (TA).

Typical Applications

• Embedded code storage Use as non-volatile program/firmware storage where parallel Flash access and a 128 Mbit capacity are required.
• System-level data storage Suitable for designs needing block-erase management and up to 100,000 erase cycles per block for robust field updates.
• Devices requiring secure identifiers Provides a 64-bit unique device identifier and 64-bit user-programmable OTP cells for device tracking and minimal on-board configuration storage.

Unique Advantages

• Flexible memory organization: Choice of x8 or x16 organization simplifies interfacing to different system bus widths.
• Verified program/erase endurance: 100,000 erase cycles per block supports frequent update scenarios and long-term field reliability.
• Hardware protection features: Protection register, sector locking, and enhanced VPEN-based protection provide layered data security options.
• Standardized interface and timing: Industry-standard pinout, CFI support, and defined 120 ns read access enable predictable integration and system compatibility.
• Wide operating range: 2.7 V to 3.6 V supply range and −40 °C to +85 °C operating temperature accommodate a broad set of power and environmental conditions.
• Compact TSOP package: 56-pin TSOP Type I (18.40 mm width) offers a compact footprint for space-constrained board designs.
