DESCRIPTION
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).
