Reference Manual (VYBRIDRM) and the corresponding datasheet on freescale.com.

3 Power use cases

The power consumption strongly depends on the application. The power requirements of your application

should be estimated referencing the following use cases.

Baremetal is the use case with the basic program running on each core. Each core controls 2 LEDs in the

infinite loop:

• Dual Core CA5 399MHz / CM4 133MHz

• VybridSC - 2LEDs each core, for CM4, for CA5, LEDs On, 100ms, LEDs Off, 100ms, SRAM,

• Configuration: TWR-VF65GS10 + TWR-ELEV + TWR-SER2

Linux use case runs Timesys LinuxLink on the primary core and playing video in WQVGA resolution:

• Single core CA5 399MHz

• All clock gates enabled, playing mp4 video in resolution 320x240

• Configuration: TWR-VF65GS10 + TWR-ELEV + TWR-SER2 + TWR-LCD-RGB

Out of the box demo (OOBE) use case runs Timesys LinuxLink on the primary core and MQX RTOS on

the secondary core:

• Dual Core CA5 399MHz / CM4 133MHz

• CM4 uses SCI2 (TWR-SER), KnightRider LEDs demo on start, welcome picture on start,

accelerometer, potentiometer, WaterFall LEDs demo, simple web server (TWR-SER2 - future)

• CA5 uses SCI1 (OpenSDA), Display QT application (TWR-LCD-RGB ), video play, WebGL web

server

• CA5 and CM4 use MMC protocol for data exchange

• Configuration: TWR-VF65GS10 + TWR-ELEV + TWR-SER2 + TWR-LCD-RGB

Reset state use case is the complementary use case for getting power consumption in the reset state,

especially TWR-LCD display background current and TWR-SER2 current:

• Configuration 1: TWR-VF65GS10 + TWR-ELEV + TWR-SER2

• Configuration 2: TWR-VF65GS10 + TWR-ELEV + TWR-SER2 + TWR-LCD-RGB
