The devices offer low-power modes including multiple sleep modes
, down to 190 nA, and up to 256 KB Flash and 16 KB RAM.
For applications demanding low power and longer battery life, the PIC32MM has sleep modes
down to 500 nA.
The sensors can detect active and sleep modes
and will monitor sleep patterns, including the time you fall asleep and length of light and deep sleep.
In this section we propose an enhancement to the smart bolt mechanism by adding a new mode to its sleep modes
which was named as deep sleep mode
These "sleep modes
" or "Off modes" greatly reduce the switching losses as well as the [I.sub.cc] consumption of the controller.
Addressing power constraints in battery-operated portable devices, ST's new gyroscope includes power-down and sleep modes
and an embedded first-in first-out memory block for smarter power management.
Another power-saving technique is used to schedule the sensor nodes to alternate between active and sleep modes
. The sensor nodes in a cluster are organized into two sets such that only one set is responsible for monitoring the targets and the other set is in sleep mode
The Dolphin platform supports self-powered two-way wireless communications, ultra low-power sleep modes
and the ability to self-power actuators such as water valves and air vents.
The processor offers power control features, including clock management and a variety of sleep modes
. In addition, the BA22 offers the best-in-class code density for similar processors, resulting in lower memory requirements and a smaller die area.
The Nap and Sleep modes
disable bus snooping; therefore a hardware handshake is provided to ensure data cache coherency before the 603 enters these power management (PM) modes.
The differing measurement requirements for active and sleep modes
might suggest the need for multiple instruments, including perhaps a DMM, a source-measure unit, and an oscilloscope.
