MT28F400B3 Overview
Writing or erasing the device is done with either a 3.3V or 5V VPP voltage, while all operations are performed with a 3.3V VCC. Due to process technology advances, 5V VPP is optimal for application and production programming. These devices are fabricated with Micron’s advanced 0.18µm CMOS floating-gate process.
