GENERAL DESCRIPTION

The MT28F008B5 (x8) and MT28F800B5 (x16/x8)

are nonvolatile, electrically block-erasable (Flash),

programmable read-only memories containing

8,388,608 bits organized as 524,288 words (16 bits) or

1,048,576 bytes (8 bits). Writing or erasing the device 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 pro-

duction programming. These devices are fabricated

with Micron’s advanced 0.18µm CMOS floating-gate

process.

The MT28F008B5 and MT28F800B5 are organized

into eleven separately erasable blocks. To ensure that

critical firmware is protected from accidental erasure

or overwrite, the devices feature a hardware-protected

boot block. This block may be used to store code

implemented in low-level system recovery. The

remaining blocks vary in density and are written and

erased with no additional security measures.

Notes:

1. This generation of devices does not support 12V VPP

compatibility production programming; however, 5V

VPP application production programming can be used

with no loss of performance.

2. Contact factory for availability.
