Low Power CMOS SRAM

Low Power CMOS SRAM
512K X 8 Bits
Features:
• Vcc operation voltage : 1.5V ~ 3.6V
• Low power consumption :
35mA (Max.) operating current
2uA (Typ.) CMOS standby current
• High Speed Access time :
70ns (Max.) at Vcc = 1.5V
• Automatic power down when chip is deselected
• Three state outputs and TTL compatible
• Data retention supply voltage as low as 1.2V
• Easy expansion with CE\ and OE\ options
UC62LV4008
-55/-70
Description
The UC62LV2008 is a high performance, very low power
CMOS Static Random Access Memory organized as 524,288
words by 8 bits and operates from 1.5V to 3.6V supply
voltage. Advanced CMOS technology and circuit techniques
provide both high speed and low power features with a
typical CMOS standby current of 2uA and maximum access
time of 70ns in 1.5V operation.
Easy memory expansion is provided enable (CE\), and
active LOW output enable (OE\) and three-state output
drivers.
The UC62LV4008 has an automatic power down feature,
reducing the power consumption significantly when chip is
deselected.
The UC62LV4008 is available in the JEDEC standard 32
pin 450mil Plastic SOP, 8mmx20.0mm TSOP (type I),
and 8mmx13.4mm STSOP.
