M5M5V408BFP/TP/RT/KV/KR
4194304-BIT (524288-WORD BY 8-BIT) CMOS STATIC RAM
DESCRIPTION
The M5M5V408B is a family of low voltage 4-Mbit static RAMs
organized as 524,288-words by 8-bit, fabricated by Mitsubishi's high-
performance 0.25µm CMOS technology.
The M5M5V408B is suitable for memory applications where a
simple interfacing , battery operating and battery backup are the
important design objectives.
M5M5V408B 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, M5M5V408BTP
(normal-lead-bend TSOP), M5M5V408BRT (reverse-lead-bend
TSOP),
M5M5V408BKV
(normal-lead-bend
STSOP)
and
M5M5V408BKR (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.

M5M5V408BFP/TP/RT/KV/KR
4194304-BIT (524288-WORD BY 8-BIT) CMOS STATIC RAM
FUNCTION
The M5M5408BFP,TP,RT,KV,KR is organized as 524,288-
words by 8-bit. These devices operate on a single +2.7~3.6V
power supply, and are directly TTL compatible to both input
and output. Its fully static circuit needs no clocks and no
refresh, and makes it useful.
A write operation is executed during the S low and W low
overlap time. The address(A0~A18) must be set up before
the write cycle
A read operation is executed by setting W at a high level
and OE at a low level while S are in an active state(S=L).
When setting S at a high level, the chips are in a non-
selectable mode in which both reading and writing are
disabled. In this mode, the output stage is in a high-impedance
state, allowing OR-tie with other chips. Setting the OE at a high
level,the output stage is in a high-impedance state, and the
data bus contention problem in the write cycle is eliminated.
The power supply current is reduced as low as 0.3µA(25°C,
typical), and the memory data can be held at +2V power
supply, enabling battery back-up operation during power failure
or power-down operation in the non-selected mode.
