LOW AVERAGE ACTIVE POWER
CMOS technology provides the STK17T88 with the
benefit of power supply current that scales with
cycle time. Less current will be drawn as the mem-
ory cycle time becomes longer than 50 ns. Figure 5
shows the relationship between ICC and READ/
WRITE cycle time. Worst-case current consumption
is shown for commercial temperature range,
VCC=3.6V, and chip enable at maximum frequency.
Only standby current is drawn when the chip is dis-
abled. The overall average current drawn by the
STK17T88 depends on the following items:
1. The duty cycle of chip enable.
2. The overall cycle rate for accesses.
3. The ratio of READs to WRITEs.
4. The operating temperature.
5. The VCC level.
6. I/O loading.
