4194304-BIT (524288-WORD BY 8-BIT) CMOS STATIC RAM
FEATURES
DESCRIPTION
• 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
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.
M5M5V408BWG is packaged in a CSP (chip scale package), with
the outline of 6mm x 10mm, ball matrix of 6 x 6 (36pin) and ball pitch
of 0.75mm. It gives the best solution for a compaction of mounting
area as well as flexibility of wiring pattern of 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.
• 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: 36 pin 6mm x10mm CSP
