A design meets its sleep current on the bench and fails to in the field. Among the following, the first thing to check is

  • A.the optimisation level chosen for the firmware build
  • B.the tick rate configured in the kernel
  • C.the size of the retained memory region
  • D.the temperature, leakage rising steeply with it

Answer: D

Leakage doubles about every ten degrees, so a part measured at twenty and deployed at sixty may draw sixteen times the sleep current. A pin left floating or a pull-up left enabled is the other usual culprit and is worth auditing at the same time.
