Power consumption performance

These Smart Remote 3 performance indications for the product example are reached by specific hardware and firmware revisions.

Hardware and firmware revisions:

Firmware settings can be modified to obtain a different set of performances.

Measurement conditions:
  • Average current, measured at battery connectors
  • DC/DC enabled, if not mentioned otherwise
  • The current measurements have been obtained with a 3.3 V power supply.
Table 1. Performances, no activity
Electrical specifications PCA20023 rev. 1.1.0/Typical value Comments/conditions
Connected idle1 19 μA Typical wakeup latency (from idle to data ready to be sent) 20 ms
Idle–Disconnected (motion wakeup using LP accelerometer) 12 μA Typical wakeup latency (from idle to data ready to be sent)

Influenced by host and matching of the crystal oscillators.
