GENERAL DESCRIPTION
The MT28F008B3 (x8) and MT28F800B3 (x16/x8)
Options Marking
are low-voltage, nonvolatile, electrically block-eras-

Configurations ing 8,388,608 bits organized as 524,288 words (16 bits)
1 Meg x 8 MT28F008B3 or 1,048,576 bytes (8 bits). Writing and erasing the
512K x 16/1 Meg x 8 MT28F800B3
device is done with a VPP voltage of either 3.3V or 5V,

while all operations are performed with a 3.3V VCC.
Top (7FFFFh) T
Due to process technology advances, 5V VPP is optimal
Bottom (00000h) B
for application and production programming. These

Extended (-40C to +85C) ET
The MT28F008B3 and MT28F800B3 are organized
Packages
into eleven separately erasable blocks. To ensure that
MT28F008B3
critical firmware is protected from accidental erasure
Plastic 40-pin (standard) TSOP Type I VG
Plastic 40-pin (lead free) TSOP Type I VP or overwrite, the devices feature a hardware-protected
MT28F800B3 boot block. This block may be used to store code
Plastic 48-pin (standard) TSOP Type I WG
implemented in low-level system recovery. The
Plastic 48-pin (lead free) TSOP Type I WP
remaining blocks vary in density and are written and

NOTE: 1. This generation of devices does not support 12V
for the latest data sheet.
VPP production programming; however, 5V VPP
application production programming can be
used with no loss of performance.
