Overview
The Micron MT29F2G01ABAGDWB-IT:G is part of Micron’s 2Gb SPI NAND Flash Memory family designed for embedded systems requiring reliable, cost-efficient, non-volatile storage. Built on SLC NAND technology and operating through the Serial Peripheral Interface (SPI), the device offers higher density and improved write performance compared with conventional SPI NOR solutions.
This industrial-grade variant operates from –40°C to +85°C, making it suitable for long-life applications in IoT, networking, industrial control, and consumer electronics.
