Product data sheet
7.23.4.1 Idle mode
7.23.4.2 Sleep mode
7.23.3 Wake-up timer
7.23.4 Power control
The LPC2361/2362 begins operation at power-up and when awakened from Power-down
and Deep power-down modes by using the 4 MHz IRC oscillator as the clock source. This
allows chip operation to resume quickly. If the main oscillator or the PLL is needed by the
application, software will need to enable these features and wait for them to stabilize
before they are used as a clock source.
When the main oscillator is initially activated, the wake-up timer allows software to ensure
that the main oscillator is fully functional before the processor uses it as a clock source
and starts to execute instructions. This is important at power on, all types of Reset, and
whenever any of the aforementioned functions are turned off for any reason. Since the
oscillator and other functions are turned off during Power-down and Deep power-down
modes, any wake-up of the processor from Power-down modes makes use of the
Wake-up Timer.
The Wake-up Timer monitors the crystal oscillator to check whether it is safe to begin
code execution. When power is applied to the chip, or when some event caused the chip
to exit Power-down mode, some time is required for the oscillator to produce a signal of
sufficient amplitude to drive the clock logic. The amount of time depends on many factors,
including the rate of V
electrical characteristics (if a quartz crystal is used), as well as any other external circuitry
(e.g., capacitors), and the characteristics of the oscillator itself under the existing ambient
conditions.
The LPC2361/2362 supports a variety of power control features. There are four special
modes of processor power reduction: Idle mode, Sleep mode, Power-down mode, and
Deep power-down mode. The CPU clock rate may also be controlled as needed by
changing clock sources, reconfiguring PLL values, and/or altering the CPU clock divider
value. This allows a trade-off of power versus processing speed based on application
requirements. In addition, Peripheral Power Control allows shutting down the clocks to
individual on-chip peripherals, allowing fine tuning of power consumption by eliminating all
dynamic power use in any peripherals that are not required for the application. Each of the
peripherals has its own clock divider which provides even better power control.
The LPC2361/2362 also implements a separate power domain in order to allow turning off
power to the bulk of the device while maintaining operation of the RTC and a small SRAM,
referred to as the battery RAM.
In Idle mode, execution of instructions is suspended until either a Reset or interrupt
occurs. Peripheral functions continue operation during Idle mode and may generate
interrupts to cause the processor to resume execution. Idle mode eliminates dynamic
power used by the processor itself, memory systems and related controllers, and internal
buses.
In Sleep mode, the oscillator is shut down and the chip receives no internal clocks. The
processor state and registers, peripheral registers, and internal SRAM values are
preserved throughout Sleep mode and the logic levels of chip pins remain static. The
output of the IRC is disabled but the IRC is not powered down for a fast wake-up later. The
