The following table illustrates typical power consumptions using these power management
mechanisms. These measurements were taken with all Digi NS9210 processor’s I/O clocks
disabled except UART A, UART C, Ethernet MAC, I/O Hub and Memory Clock0 with the
ethernet connected to a 100Mb network, using a standard module plugged into a Digi
JumpStart Kit development board, with nominal voltage applied:
Note 1: This measurement was taken from the R6 current sense resistor using a 0.025 ohm shunt on the
JumpStart Kit development board.
Note 2: This is the default power consumption mode when entering applicationStart(), as measured with the
napsave sample application. The value of the NS9210 Clock Configuration register (A090017C) is 0001200B
hexadecimal.
Note 3: This measurement was produced by selecting the “Clock Scale” menu option in the napsave sample
application.
Note 4: This measurement was produced by selecting the “Deep Sleep/Wakeup with an External IRA” menu
option in the napsave sample application.
