MSM9892L
2M-bit Serial Voice Flash Memory
GENERAL DESCRIPTION
TheMSM9892Lisa2Mbflashmemorythatoperatesat2.7Vto3.6V. Sincebackupisnotneeded,
the number of pins is small, and the pins are contained in a small-package 28-pin TSOP, the
MSM9892L is a flash memory suitable for applications such as handy terminals. In combination
withOKI'srecording/playbackIC(MSM9888L),asolid-staterecording/playbacksystemcanbe
easily constructed.

WRITE DISTURB
"Write Distrub" means a phenomenon that the change from digital "0" to "1" may occur in a Flash
memory page to which data is scarcely written.
The above change can be avoided by refreshing Flash memory data with the DTRW command
and WEND command of the MSM9888L/MSM9889L.

TIMING WHEN POWER IS ON
Refer to the MSM9888L/MSM9889L Data Sheet. If the timing diagrams described in the
MSM9888L/MSM9889L Data Sheet are not satisfied, errors such as "Recording is disabled" or
"Recorded message is erased" may occur.

Notes for Mounting the Surface Mount Type Package
The SOP, QFP, TSOP, TQFP, LQFP, SOJ, QFJ (PLCC), SHP, and BGA are surface mount type
packages, which are very susceptible to heat in reflow mounting and humidity absorbed in
storage. Therefore, before you perform reflow mounting, contact Oki’s responsible sales person
ontheproductname,packagename,pinnumber,packagecodeanddesiredmountingconditions
(reflow method, temperature and times).
