Low Power CMOS SRAM
256K X 8 Bits
UC62LV2008
-55/-70
Features:
• Vcc operation voltage : 1.5V ~ 3.6V
• Low power consumption :
15mA (Max.) operating current
1uA (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
Description
The UC62LV2008 is a high performance, very low power
CMOS Static Random Access Memory organized as 262,144
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 1uA 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 UC62LV2008 has an automatic power down feature,
reducing the power consumption significantly when chip is
deselected.
The UC62LV2008 is available in the JEDEC standard 32 pin
450mil Plastic SOP, 8mmx20.0mm TSOP (type I), and
8mmx13.4mm STSOP.

NOTES:
1. WE\ is high in read cycle.
2. Device is continuously selected when CE\ = VIL
3. Address valid prior to or coincident with CE\ transition low.
4. OE\ = VIL.
5. Transition is measured ±500mV from steady state with CL=5pF as shown in Figure 1B. The
parameter is guaranteed but not 100% tested.
