Power Consumption Specifications
Table 5
CYONS2100.
In general, there are two components to total current
consumption. The first is the total current drawn by the DVDD,
AVDD, VREGA, and VREGD pins. The second is the current
drawn by the internal regulator that drives these pins.
For externally powered designs, no internal regulator is active,
and no additional current is present.
For designs powered by the VDD5V pin, the 5V-to-3V regulator
is active, and the current consumption of this block, specified in

directly from this regulator, so USB-based designs should
include the additional current.
Sleep current is achieved by activating power-saving modes
through firmware. Doing so enables the sleep mode progres-
sions described earlier, and also causes the laser and detector
circuitry to turn on and off as needed to minimize power. For the
CYONS2100, low-power operation is only needed to support
USB Suspend. Reference code for this is available in the
CY4631 Wired Mouse Reference Design Kit. If sleep modes are
not activated, the device current stays at tracking current levels,
even when the device is not sensing motion.
