Application Note
© 2013 Freescale Semiconductor, Inc. All rights reserved.
1 Overview
Vybrid controller solutions are built on the new
asymmetrical multiprocessing architecture using ARM
cores. The purpose of this application note is to provide an
overview of the power consumption Vybrid controller
solutions. The document is focused on normal run modes.
Several Vybrid use cases were defined and the power
consumptions measured using The Freescale Tower System
module (TWR-VF65GS10). To increase power efficiency,
several power supply options are presented, including ballast
transistor selection notes.
2 Vybrid controller solutions
overview
The Vybrid controller solutions are designed for rich
applications in real time. The primary features of the Vybrid
controller solutions include:
Two ARM cores build on 40nm technology process
Cortex-A5 core: 266, 400-500MHz – rich
applications; 8 stage pipeline; 1.57 DMIPS /
