Very Low Power/Voltage CMOS SRAM

32K X 8 bit

STC

STC62WV256

DESCRIPTION

FEATURES

• Wide Vcc operation voltage : 2.4V ~ 5.5V

• Very low power consumption :

The STC62WV256 is a high performance , very low power CMOS

Static Random Access Memory organized as 32,768 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

0.01uA and maximum access time of 70ns in 3V operation.

Easy memory expansion is provided by active LOW chip enable (CE),

active LOW output enable (OE) and three-state output drivers.

The STC62WV256 has an automatic power down feature, reducing the

power consumption significantly when chip is deselected.

Vcc = 3.0V C-grade : 20mA (Max.) operating current

I- grade : 25mA (Max.) operating current

0.01uA (Typ.) CMOS standby current

Vcc = 5.0V C-grade : 35mA (Max.) operating current

I- grade : 40mA (Max.) operating current

0.4uA (Typ.) CMOS standby current

• High speed access time :

-70

70ns (Max.) at Vcc=3.0V

The STC62WV256 is available in the DICE form, JEDEC standard 28pin

330mil Plastic SOP, 300mil Plastic SOJ, 600mil Plastic DIP and 8mm x

13.4mm TSOP (normal type).

• 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 CE and OE options
