SYSTEM CONTROL INFORMATION
Interfacing with the Samsung S5PC100, S5PC110 and S5PV210 Processors
The ACT8897 is optimized for use in applications
using the S5PC100, S5PC110 and S5PV210
processors, supporting both the power domains as
well as the signal interface for these processors.
The following paragraphs describe how to design
ACT8897 with S5PV210 Processor, but the design
guidelines are directly applicable to S5PC100 and
S5PC110 as well.
While the ACT8897 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 ACT8897 pin names and functions. However, in
cases where the description of interconnections
between these devices benefits by doing so, both
the ACT8897 pin names and the Samsung
processor pin names are provided. When this is
done, the S5PV210 pin names are located after the
ACT8897 pin names, and are italicized and located
inside parentheses. For example, PWREN
(XPWRRGTON) refers to the logic signal applied to
the ACT8897's PWREN input, identifying that it is
driven from the S5PV210's XPWRRGTON output.
Likewise, OUT1 (VDD_IO) refers to ACT8897's
OUT1 pin, identifying that it is connected to the
S5PV210's VDD_IO power domain.
