Product Overview
MT25QU512ABB1EW9-0SIT is Micron’s 512Mb (64MB) industrial serial NOR Flash operating at 1.8V. It supports Single/Dual/Quad SPI and Twin-Quad DTR interfaces for fast boot and high throughput. Built with uniform 4KB/32KB/64KB memory blocks, it delivers stable read performance, 100,000 program/erase cycles and 20-year data retention. Packaged in compact WPDFN-8 (8×6mm) SMD form, it fits FPGA configuration, automotive infotainment, network switches and industrial controller firmware storage.
Core Advantages
SuperSpeed Quad I/O and Twin-Quad Throughput
Up to 166 MHz STR clock and 90 MHz DTR frequency, delivering high-speed transmission to meet fast-boot demands of embedded processors and FPGAs.
Eco-Friendly Low 1.8V Power Architecture
1.7V~2.0V single-rail supply cuts dynamic & standby power draw versus old 3.3V flash, ideal for heat-limited compact PCBs.
Robust Security and Device Integrity Protection
Hardware sector write lock + lockable 64-byte OTP zone prevents accidental overwriting or tampering of boot firmware.
Uniform Block and Sector Architecture Flexibility
Standardized 4KB/32KB/64KB memory partitions simplify firmware partition management and wear leveling tuning.
Uniform Block and Sector Architecture Flexibility
Utilizes symmetrical 64KB blocks and 4KB sectors across the entire memory space, allowing embedded firmware developers to easily organize data storage, speed up page rewrite cycles, and optimize wear-leveling efficiency.

Frequently Asked Questions
Q1: Is your currently available inventory of the MT25QU512ABB1EW9-0SIT 100% genuine and factory-original?
A: Yes, we guarantee that all MT25QU512ABB1EW9-0SIT components in our warehouse are 100% brand-new, original factory stock from Micron Technology. Every order batch is tracked, logged, and shipped inside standard moisture-sensitive anti-static ESD shielding wrappers.
Q2: Can this 1.8V NOR Flash device be connected directly to a microcontroller operating on a 3.3V I/O bank?
A: No, the MT25QU512ABB1EW9-0SIT operates strictly within a 1.7V to 2.0V voltage tolerance window. Connecting it directly to 3.3V logic signals can permanently damage the silicon. If your main controller uses 3.3V, you must use a bidirectional logic level shifter between the interfaces.
Q3: What does the specific “1EW9” string designate in Micron’s package ordering hierarchy?
A: In Micron’s part numbering system, the “EW9” indicator specifies an 8-contact WPDFN package layout configuration measuring 8mm x 6mm. The preceding “1” designates that the package material utilizes a standard, lead-free green compound formulation.
Q4: How can our technical division request hardware initialization source code, reference layout guidelines, or ask for special volume pricing structures?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
