Typical module current / power measurements

The following illustrates typical power consumption when all clocks are active and

the ethernet is connected to a 100Mb network.

1 VLIO is supplying the core voltage regulator. This value is reached when all clocks are on. This typ-
ical measurement was made with VLIO set to 3.3V. VLIO can vary between 2.5V to 5.0V.
2 This value is reached when Ethernet is activated. This typical measurement was made with +3.3V set
to 3.3V. +3.3V can vary between 3.1V to 3.6V.
3 FIM is the Flexible Interface Module.
4 DRPIC is a High performance 8-bit RISC Microcontroller.

power consumption measurements

The following table illustrates typical power consumption using various NS9215

power management mechanisms. These measurements were taken with all NS9215

I/O clocks disabled except UART B, UART D, Ethernet MAC, I/O Hub, and the

Memory Clock0 and the ethernet connected to a 100Mb network, using a standard

module plugged into a JumpStart Kit board, with nominal voltage applied:

1 This measurement was taken from the R80 current sense resistor (0.025 ohm) on the JumpStart Kit
development board.
2 This measurement represents only the current of the VLIO and +3.3V inputs to the module, measured
from the two current sense resistors R81 and R94 (0.025 ohm) located on the JumpStart Kit develop-
ment board.
3 This is the default power consumption mode when entering applicationStart(), as measured with the
napsave sample application. The value of the NS9215 Clock Configuration register (A090017C) is
02012015 hexadecimal.
4 This measurement was produced by selecting the "Clock Scale" menu option in the napsave sample
application.
5 This measurement was produced by selecting the "Deep Sleep/Wakeup with an External IRQ" menu
option in the napsave sample application.
