MT28F128J3BS-12 ET

The MT28F128J3BS-12 ET is a 128 Mbit non-volatile FLASH memory device in a 64-ball FBGA (10×13) package with a parallel interface. It implements Micron’s Q-FLASH architecture with x8/x16 organization and industry-standard pinout for TTL-compatible inputs and outputs.

This device is designed for systems that require parallel FLASH storage with defined timing and power envelopes: 120 ns read access (128 Mb), 2.7 V–3.6 V supply operation, and an extended operating temperature range of −40°C to +85°C.

Key Features

• Memory Capacity & Organization — 128 Mbit total capacity organized as 16M × 8 or 8M × 16, providing flexible bus-width options for system integration.
• Architecture & Erase Granularity — Q-FLASH device with one hundred twenty 128 KB erase blocks (for the 128 Mb density), enabling block-based erase and management.
• Read Performance — Asynchronous page mode reads with 120 ns primary read access time (128 Mb) and 25 ns secondary timing metric.
• Power & Programming — Operates and programs at VCC/VCCQ/VPEN from 2.7 V to 3.6 V; effective programming via write buffer yields 5.6 μs-per-byte effective programming time using the write-buffer algorithm.
• Data Protection & Security — 128-bit protection register, 64-bit unique device identifier, 64-bit user-programmable OTP cells, enhanced data protection feature with VPEN = VSS, and flexible sector locking with lockout during power transitions.
• Reliability & Lifecycle — Specified for 100,000 erase cycles per block and supports automatic suspend options (block erase/program suspend-to-read and program suspend-to-read) to improve system responsiveness during maintenance operations.
• Interface & Compatibility — Parallel memory interface with industry-standard pinout; inputs and outputs are fully TTL-compatible. Includes Common Flash Interface (CFI) and Scalable Command Set support.
• Package & Temperature — 64-FBGA (10×13) supplier device package with an extended operating temperature range of −40°C to +85°C (TA).

Typical Applications

• Firmware and Code Storage — Non-volatile FLASH storage for system firmware and boot code in embedded platforms requiring parallel memory access.
• System Configuration Storage — Storage of configuration tables, device identifiers, and user-programmable OTP data where block-level erase and protection are required.
• Industrial and Extended-Temperature Systems — Use in systems operating across −40°C to +85°C that need robust erase/program endurance and protection features.

Unique Advantages

• Flexible Bus Widths — Support for x8 and x16 organizations enables adaptation to multiple system bus architectures without changing core device features.
• Block-Level Control — 128 KB erase block architecture and sector locking provide fine-grained control for firmware updates and data protection.
• Extended Voltage Range — 2.7 V–3.6 V operation simplifies integration with common 3.3 V system rails.
• Integrated Identification & Security — 64-bit unique device identifier and 64-bit user-programmable OTP cells allow device-level tracking and secure storage of critical data.
• Suspend/Resume Operations — Automatic suspend options (erase/program suspend-to-read) allow reads to continue during long program/erase cycles, improving system availability.
• Defined Endurance & Programming Metrics — 100,000 erase cycles per block and 5.6 μs-per-byte effective programming time using the write buffer provide verifiable lifecycle and performance characteristics.
