2097152-BIT (262144-WORD BY 8-BIT) CMOS STATIC RAM
FEATURES
The M5M5V208A is a family of low voltage 2-Mbit static RAMs
organized as 262,144-words by 8-bit, fabricated by Mitsubishi's high-
performance 0.25µm CMOS technology.
The M5M5V208A is suitable for memory applications where a
simple interfacing , battery operating and battery backup are the
important design objectives.
The M5M5V208A is packaged in 32-pin 8mm x 13.4mm STSOP
packages. Two types of STSOPs are available, M5M5V208AKV
(normal-lead-bend STSOP) and M5M5V208AKR (reverse-lead-bend
STSOP). These 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.
• Single 2.7 ~ 3.6V power supply
• No clocks, No refresh
• All inputs and outputs are TTL compatible.
• Easy memory expansion and power down by S1 & S2
• Data retention supply voltage=2.0V
• Three-state outputs: OR-tie capability
• OE prevents data contention in the I/O bus
• Common Data I/O
• Battery backup capability
• Small stand-by current • • • • • • • • • • 0.3µA(typ.)
