FEATURES
1
The M5M5408B is a family of 4-Mbit static RAMs organized as
524,288-words by 8-bit, fabricated by Mitsubishi's high-
performance 0.25μm CMOS technology.
The M5M5408B is suitable for memory applications where a
simple interfacing , battery operating and battery backup are the
important design objectives.
M5M5408B is packaged in 32-pin plastic SOP, 32-pin plastic
TSOP and 32-pin 8mm x 13.4mm STSOP packages. Two types of
TSOPs and two types of STSOPs are available , M5M5408BTP
(normal-lead-bend TSOP) , M5M5408BRT (reverse-lead-bend
TSOP)
,
M5M5408BKV
(normal-lead-bend
M5M5408BKR (reverse-lead-bend STSOP). These two types
TSOPs and two types STSOPs are suitable for a surface mounting
on double-sided printed circuit boards.
From the point of operating temperature, the family is divided
into three versions; "Standard", "
W
-version", and "
I
-version". Those
are summarized in the part name table below.
