MT28F400B3
Description
The MT28F004B3 (x8) and MT28F400B3 (x16/x8) are nonvolatile, electrically block-erasable (flash), programmable memory devices containing 4,194,304 bits organized as 262,144 words (16 bits) or 524,288 bytes (8 bits). 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.
