MX66C256

Very Low Power 32k x 8 CMOS SRAM

DESCRIPTION

FEATURES

The MX66C256 is a high performance, very low power

CMOS Static Random Access Memory organized as

32,768 words by 8 bits and operates at 5.0V supply

voltage.

Advanced CMOS technology and circuit techniques

provide both high speed and low power features with a

typical CMOS standby current of 0.4uA and maximum

access time of 70ns and 100 ns in 5V operation.

Easy memory expansion is provided by an active LOW

chip enable(CE), and active LOW output enable (OE)

and three-state output drivers.

The MX66C256 has an automatic power down feature,

reducing the power consumption significantly when chip

is deselected.

The MX66C256 is available in the JEDEC standard 28

pin 330mil Plastic SOP, and 8mmx13.4mm TSOP

(normal type).

Vcc operation voltage : 5.0V

Very low power consumption :

50 mA (Max.) write current

40 mA (Max.) read current

0.4uA (Typ.) CMOS standby current

High speed access time :
