4194304-BIT (524288-WORD BY 8-BIT) CMOS STATIC RAM
FEATURES
DESCRIPTION
• Single +5V power supply
• Small stand-by current: 0.4µA(3V,typ.)
• No clocks, No refresh
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.
• Data retention supply voltage=2.0V to 5.5V
• All inputs and outputs are TTL compatible.
• Easy memory expansion by S
• Common Data I/O
• Three-state outputs: OR-tie capability
• OE prevents data contention in the I/O bus
• Process technology: 0.25µm CMOS
• Package:
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 STSOP) and
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.
M5M5408BFP: 32 pin 525 mil SOP
M5M5408BTP/RT: 32 pin 400 mil TSOP(ll)
M5M5408BKV/KR: 32 pin 8mm x 13.4mm STSOP
