FEATURES
DESCRIPTION
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.)

FUNCTION
The operation mode of the M5M5V208A is determined by a
combination of the device control inputs S1, S2, W and OE.
Each mode is summarized in the function table.
A read cycle is executed by setting W at a high level and
OE at a low level while S1 and S2 are in an active state (S1
= L ,S2 = H).
When setting S1 at a high level or S2 at a low level, the
chips are in a non-selectable mode in which both reading
and writing are disabled. In this mode, the output stage is in
a high-impedance state, allowing OR-tie with other chips
and memory expansion by S1 or S2. The power supply
current is reduced as low as the stand-by current which is
specified as Icc3 or Icc4, and the memory data can be held
at +2V power supply, enabling battery back-up operation
during power failure or power-down operation in the non-
selected mode.
A write cycle is executed whenever the low level W
overlaps with the low level S1 and the high level S2. The
address must be set up before the write cycle and must be
stable during the entire cycle. The data is latched into a cell
on the trailing edge of W, S1 or S2, whichever occurs first,
requiring the set-up and hold time relative to these edge to
be maintained. The output enable OE directly controls the
output stage. Setting the OE at a high level,the output stage
is in a high-impedance state, and the data bus contention
problem in the write cycle is eliminated.
