The ACT8846 is optimized for the Rockchip

RK31x8 processors, supporting both the power

domains as well as the signal interface. The

following paragraphs describe how to design

ACT8846 with the RK31x8 processors.

While the ACT8846 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 ACT8846 pin names and functions. However, in

cases where the description of interconnections

between these devices benefits by doing so, both

the ACT8846 pin names and the RK31x8

processors pin names are provided. When this is

done, the RK31x8 pin names are located after the

ACT8846 pin names, and are italicized and located

inside parentheses. For example, PWREN (GPIOX)

refers to the logic signal applied to the ACT8846's

PWREN input, identifying that it is driven from the

RK31x8's GPIOX output.
