To all our customers
Regarding the change of names mentioned in the document, such as Mitsubishi
Electric and Mitsubishi XX, to Renesas Technology Corp.
The semiconductor operations of Hitachi and Mitsubishi Electric were transferred to Renesas
Technology Corporation on April 1st 2003. These operations include microcomputer, logic, analog
and discrete devices, and memory chips other than DRAMs (flash memory, SRAMs etc.)
Accordingly, although Mitsubishi Electric, Mitsubishi Electric Corporation, Mitsubishi
Semiconductors, and other Mitsubishi brand names are mentioned in the document, these names
have in fact all been changed to Renesas Technology Corp. Thank you for your understanding.
Except for our corporate trademark, logo and corporate statement, no changes whatsoever have been
made to the contents of the document, and these changes do not constitute any alteration to the
contents of the document itself.
Note : Mitsubishi Electric will continue the business operations of high frequency & optical devices
and power devices.

M5M5408BFP/TP/RT
4194304-BIT (524288-WORD BY 8-BIT) CMOS STATIC RAM
DESCRIPTION
The M5M5408B is a f amily of 4-Mbit static RAMs organized
as 524,288-words by 8-bit, f abricated by Mitsubishi's high-
perf ormance 0.25µm CMOS technology .
The M5M5408B is suitable f or memory applications where a
simple interf acing , battery operating and battery backup are
the important design objectiv es.
M5M5408B is packaged in 32-pin plastic SOP, 32-pin plastic
TSOP. Two ty pes of TSOPs are av ailable, M5M5408BTP
(normal-lead-bend TSOP) , M5M5408BRT (rev erse-lead-bend
TSOP). These two ty pes TSOPs are suitable f or a surf ace
mounting on double-sided printed circuit boards.
From the point of operating temperature, the f amily is
div ided into two v ersions; "Standard" and "I-v ersion". Those are

M5M5408BFP/TP/RT
4194304-BIT (524288-WORD BY 8-BIT) CMOS STATIC RAM
FUNCTION
The M5M5408BFP,TP,RT is organized as 524,288-words
by 8-bit. These dev ices operate on a single +5.0V power
supply , and are directly TTL compatible to both input and
output. Its f ully s t atic circuit needs no clocks and no
ref resh, and makes it usef ul.
A write operation is executed during the S# low and W#
low ov erlap time. The address(A0~A18) must be set up
bef ore the write cy c le
A read operation is executed by s etting W# at a high
lev el and OE# at a low lev el while S# are in an activ e
state (S#=L).
When setting S# at a high lev el, 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 lev el,the output stage is in a high-
impedance state, and the data bus contention problem in
the write cy c le is eliminated.
The power supply c urrent is reduced as low as 0.4µA
(25°C, ty pical), and the memory data can be held at +2V
power supply , enabling battery back-up operation during
power f ailure or power-down operation in the non-selected
mode.
