DESCRIPTION
FEATURES
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 and 32-pin plastic
TSOP packages. Two types of TSOPs are available ,
M5M5408BTP (normal-lead-bend TSOP) and M5M5408BRT
(reverse-lead-bend TSOP). These two types TSOPs 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.
• Single +5V power supply
• Small stand-by current: 0.4µA(3V,typ.)
• No clocks, No refresh
• 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:
M5M5408BFP: 32 pin 525 mil SOP
M5M5408BTP/RT: 32 pin 400 mil TSOP(ll)
