ꢀDescription
The UC62LS1008 is a high performance, very low power
CMOS Static Random Access Memory organized as 131,072
words by 8 bits and operates from 3.0V 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 1uA and maximum access
time of 25ns in 3.0V operation.
25ns (Max.) at Vcc = 3.0V
• 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
Easy memory expansion is provided enable (CE\), and
active LOW output enable (OE\) and three-state output
drivers.
The UC62LS1008 has an automatic power down feature,
reducing the power consumption significantly when chip is
deselected.
The UC62LS1008 is available in the JEDEC standard 32 pin
450mil Plastic SOP, 8mmx20.0mm TSOP (type I), and
8mmx13.4mm STSOP.
