The MBM29LV160TM/BM supports command set compatible with JEDEC single-power-supply EEPROMS stan-
dard. Commands are written into the command register. The register contents serve as input to an internal state-
machine which controls the erase and programming circuitry. Write cycles also internally latch addresses and
data needed for the programming and erase operations. Reading data out of the devices is similar to reading
from 5.0 V and 12.0 V Flash or EPROM devices.
The MBM29LV160TM/BM is programmed by executing the program command sequence. This will invoke the
Embedded Program Algorithm
and verifies proper cell margin. Erase is accomplished by executing the erase command sequence. This will
invoke the Embedded Erase Algorithm
if it is not already programmed before executing the erase operation. During erase, the device automatically
times the erase pulse widths and verifies proper cell margin.
The device also features a sector erase architecture. The sector mode allows each sector to be erased and
reprogrammed without affecting other sectors. All sectors are erased when shipped from the factory.
The device features single 3.0 V power supply operation for both read and write functions. Internally generated
and regulated voltages are provided for the program and erase operations. A low V
inhibits write operations on the loss of power. The end of program or erase is detected by Data Polling of DQ

Fujitsu Flash technology combines years of Flash memory manufacturing experience to produce the highest
levels of quality, reliability, and cost effectiveness. The devices electrically erase all bits within a sector simulta-
neously via hot-hole assisted erase. The bytes/words are programmed one bytes/words at a time using the
EPROM programming mechanism of hot electron injection.
