The ACT8849 is optimized for the Samsung

Exynos4412 and other application processors,

supporting both the power domains as well as the

signal interface. The following paragraphs describe

how to design ACT8849 with the Exynos4412

processors.

While the ACT8849 supports many possible

configurations for powering these processors, one

of the most common configurations is detailed in

this datasheet. In general, this document refers to

the ACT8849 pin names and functions. However, in

cases where the description of interconnections

between these devices benefits by doing so, both

the ACT8849 pin names and the Exynos4412

processors pin names are provided. When this is

done, the Exynos4412 pin names are located after

the ACT8849 pin names, and are italicized and

located inside parentheses. For example, PWREN

(XPWRRGTON) refers to the logic signal applied to

the ACT8849's PWREN input, identifying that it is

driven from the Exynos4412's XPWRRGTON

output.
