7.5.2
Using VV6410/6500 (sensor operates at @ 3.3V DC)
Notes:
1. See Table 11 on page page 26. However, STV0680A mean current consumption is to be determined by measurement of
sample quantity in due course.
2. From limited evaluation, typical self-refresh current figures of certain SDRAM chips are well below manufacturers’ maximum
specification, e.g. 100-250
μ
A. See Section 9. for recommendations.
3. Sensor suspend mode current <100
μ
A when SUSPEND pin asserted, see Table 18 and Table 19.
4. If the appropriate hardware to assert the sensor SUSPEND pin is not fitted, an addditional current consumption in this mode
of up to 200
μ
A can be expected.

’Snapshot’/Continuous/
Self timer mode (while
un-tethered)
60mA
Assuming appropriate hardware included, power is sourced from PC
while USB connected.
’Snapshot’/Continuous/
Self timer mode (while
tethered to PC)
60mA
Standby Mode (when
NOT connected to USB):
Sensor SUSPEND pin
asserted (see note 4)
Approx. 0.5mA +
SDRAM self-
refresh current (see
note 2)
Total current in this mode equals:
STV0680A Standby current consumption (see note 1)
+ SDRAM self-refresh current (see note 2)
+ peripheral circuitry (approx. 50
μ
A).
+ Sensor suspend mode current (See note 3)
PC Suspend mode
(when connected to
USB): Sensor SUSPEND
pin asserted (see note 4)
Approx. 0.7mA +
SDRAM self-
refresh current (see
note 2)
Total current in this mode equals:
STV0680A Standby current consumption (see note 1)
+SDRAM self-refresh current (see note 2)
+ peripheral circuitry (approx. 50
μ
A).
+ 200
μ
A , based on 1.5k pull-up in camera (see Section 9.) and 15k
pull-down in PC.
+ Sensor suspend mode current (See note 3)
