U630H64
The information describes the type of component and shall not be considered as assured characteristics. Terms of
delivery and rights to change design reserved.
Low Average Active Power
The U630H64 has been designed to draw significantly
less power when E is LOW (chip enabled) but the
access cycle time is longer than 55 ns.
When E is HIGH the chip consumes only standby cur-
rent.
The overall average current drawn by the part depends
on the following items:
1. CMOS or TTL input levels
2. the time during which the chip is disabled (E HIGH)
3. the cycle time for accesses (E LOW)
4. the ratio of READs to WRITEs
5. the operating temperature
6. the V
CC
level
