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.
FEATURES
• Single +2.7~+3.6V power supply
• Small stand-by current: 0.3µA(3V,typ.)
• No clocks, No refresh
• Data retention supply voltage=2.0V to 3.6V
• 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:
M5M5V408BFP: 32 pin 525 mil SOP
M5M5V408BTP/RT: 32 PIN 400mil TSOP(ll)
M5M5V408BKV/KR: 32 pin 8mm x13.4mm STSOP
