Description
The UC62LV0256 is a high performance, very low power
CMOS Static Random Access Memory organized as 32,768
words by 8 bits and operates from a wide range of 2.0V 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 70ns in 2.0V operation.
Easy memory expansion is provided enable (CE), and
active LOW output enable (OE) and three-state output
drivers.
The UC62LV0256 has an automatic power down feature,
reducing the power consumption significantly when chip is
deselected.
The UC62LV0256 is available in the JEDEC standard 28 pin
330mil Plastic SOP, 300mil Plastic SOJ, 600mil Plastic DIP
and 8mmx13.4mm TSOP (normal type).

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.
