Navigation and Click
Modes Current
Consumption
Static Current Consumption
The SPI bus’ consumption is very low in click and navigation modes, the majority of the
consumption being generated by the analog part of the circuit. Therefore, the static and
dynamic consumption is almost the same.
Dynamic Current
Consumption
With a 30 pF load at maximum clock frequency, the current consumption in click mode is
almost 300 μA on pins V
DD
. With a 30 pF load at maximum clock frequency, the current
consumption in navigation mode is approximately 1.5 mA.
Note:
We advise use of the interrupt capabilities (IRQ signal or Interrupts register) so as to limit
the host’s overall current consumption. The host can, from time to time, check the IRQ or
Interrupt register. A strategy for very low power consumption is to use the click mode only
as a wake-up. The click mode is only 300 μA, and once a click is detected the host can
turn on the navigation mode as well.
