9.3 Device Power Consumption in Applicative Use Cases

Table 9-4 provides the device power consumption in the following conditions:

f_{CPU_CLK}: 1 GHz
f_MCK1: 200 MHz
f_MCK2: 533 MHz
f_MCK3: 266 MHz
f_MCK4: 400 MHz
I and D caches enabled
Use cases run on Linux®
Ambient temperature: 25°C
Current consumptions are measured as shown in Figure 9-1. Note that the external component current consumptions are not counted.

Table 9-3 reports active power consumption data measured on a few SAMA7G5 SiP typical process samples. These data do not include specifications for maximum power consumption.

Table 9-3. Use Case Definition
Use Case	Description
1	Audio MP3 decoding and playback on I²S; MP3 file on USB mass storage
2	SAMA7G54 running as iPerf server
3	Run Bonnie++ on USB mass storage
4	SAMA7G54 downloads a file from GMAC0 and copies this file to USB mass storage
5	Streaming camera on Ethernet (image format: RAW8, 1080p @ 30 fps)
