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.
The MT28F004B3 and MT28F400B3 are organized into seven separately erasable blocks.
To ensure that critical firmware is protected from accidental erasure or overwrite, the devic...
