IOT Landscape


When is power management important?

10

It should always should be considered a crucial feature • Alongside areas such

as security • Even if the scenario

doesn’t appear to require careful power management

• Not just for items such as wearables or smartphones


MediaTek’s focus MediaTek has legacy of low-

power, small footprint solutions • Existing solutions in the LinkIt

portfolio have class-leading low-power capabilities

• Pioneering use of multi-mode options

MediaTek continues to focus on low-power, high performance New SoCs such as the MT2523 and

MT7687 include PMU support

12

Identifying power saving opportunities

Need to identify all possible behaviors • Use-case modelling • Likely areas of compromise vs non-

negotiable behavior

Power mode flows • Including transitions from one-state to

another

Connectivity • Which protocol best suits usage? • Always-on?

13
