STC
Very Low Power/Voltage CMOS SRAM
1M X 8 bit
STC62WV1M8
FEATURES
• Wide Vcc operation voltage : 2.4V ~ 5.5V
• Very low power consumption :
Vcc = 3.0V C-grade: 30mA (@55ns) operating current
I -grade: 31mA (@55ns) operating current
C-grade: 24mA (@70ns) operating current
I -grade: 25mA (@70ns) operating current
1.5uA (Typ.) CMOS standby current
Vcc = 5.0V C-grade: 75mA (@55ns) operating current
I -grade: 76mA (@55ns) operating current
C-grade: 60mA (@70ns) operating current
I -grade: 61mA (@70ns) operating current
8.0uA (Typ.) CMOS standby current
• High speed access time :
-55 55ns
-70 70ns
• Automatic power down when chip is deselected
• Three state outputs and TTL compatible
• Fully static operation
• Data retention supply voltage as low as 1.5V
• Easy expansion with CE1, CE2 and OE options
GENERAL DESCRIPTION
The STC62WV1M8 is a high performance , very low power CMOS Static
Random Access Memory organized as 1,048,576 words by 8 bits and
operates from a wide range of 2.4V to 5.5V supply voltage.
Advanced CMOS technology and circuit techniques provide both high
speed and low power features with a typical CMOS standby current of
1.5uA at 3V/25oC and maximum access time of 55ns at 3.0V/85oC.
Easy memory expansion is provided by an active LOW chip enable (CE1)
, an active HIGH chip enable (CE2) and active LOW output enable (OE)
and three-state output drivers.
The STC62WV1M8 has an automatic power down feature, reducing the
power consumption significantly when chip is deselected.
The STC62WV1M8 is available in 48B BGA and 44L TSOP2 packages.

NOTES:
1. WE is high in read Cycle.
2. Device is continuously selected when CE1 = VIL and CE2 = VIH.
3. Address valid prior to or coincident with CE1 transition low and CE2 transition high.
4. OE = VIL .
5. The parameter is guaranteed but not 100% tested.
