Product Summary

The MT28F400B5 is an nonvolatile, electrically block-erasable (Flash), programmable, read-only memory containing 4,194,304 bits organized as 262,144 words (16 bits) or 524,288 bytes (8 bits). Writing or erasing the MT28F400B5 is done with a 5V VPP voltage, while all operations are performed with a 5V VCC. Due to process technology advances, 5V VPP is optimal for application and production programming. The MT28F400B5 is fabricated with Micron’s advanced 0.18µm CMOS floating-gate process.
