VULCAN Technical Manual

Power and power management

Power management

The IXP425 processor does not include any internal power management features,

however the VULCAN board does allow power control to some on board peripherals.

These include:

•

UART.

•

CompactFlash.

•

Ethernet.

•

USB.

•

Clock generator.

These are explained in the following sections.

UART power management

COM3 and COM4 are implemented using external XR16L2551 DUART. This device

supports a sleep mode with an automatic wake up. When this feature is enabled and

there are no interrupts pending, the DUART enters sleep mode. The XR16L2551 stops

its crystal oscillator to conserve power in the sleep mode. The part resumes normal

operation when any of the following occur:

•

Receive data start bit.

•

Change of state on: CTS, DSR, CD, RI.

•

Data is being loaded into transmit FIFO.

If the part was awakened by one of the above conditions, it returns to sleep mode

automatically after the condition has cleared.

Using the PowerSave feature of XR16L2551 it is possible to reduce power

consumption even further. The L2551 enters PowerSave mode when the PWRSAVE

pin is logic high and the XR16L2551 is in sleep mode. This internally isolates the

address, data and control signals from other bus activities. The device wakes up as a

result of a receive data start bit transition or a change of logic state on any of the

modem or general-purpose serial inputs: CTS#, DSR#, CD#, RI#.

Placing the XR16L2551 into low power mode can reduce the power consumption of

the VULCAN by 10mW. Please refer to the XR16L2551 datasheet, on the

Development Kit CD, for details about enabling the sleep and PowerSave modes.
