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 production 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.

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.
