System on a Chip Guide — 9S12UF32DGV1/D V01.05
Section 2 Signal Description
The 9S12UF32 has two package options, the first one is a full featured 100-pin package and the second
one in a low cost 64-pin package.
In the 100-pin option, three primary software selectable configurations are available for different end
applications.
USB 2.0 to ATA and CF bridge
USB 2.0 to ATA, SM, SD (MMC) and MS bridge
USB 2.0 to CF, SM, SD (MMC) and MS bridge
Below table shows a summary of how the above configurations can be selected.
In the 64-pin option, four primary software selectable configurations are available for different end
applications.
USB 2.0 to ATA bridge with optional SDHC support
USB 2.0 to SM, SD (MMC) and MS bridge

Specic Notes
When TIMER is enabled,
timer channel pins IOC[7:4]
will be available on PR[7:4]
if CA10E, CA9E, CA8E and
CA7E in CFSCR2 of CFHC
are set to 0.
When SCI is enabled, SCI
module pins TXD and RXD
will be available on PR[3:2]
if CA6E and CA5E in
CFSCR2 of CFHC are set to
0.
None
When TIMER is enabled,
timer channel pins IOC[7:4]
will be available on PR[7:4]
if CA10E, CA9E, CA8E and
CA7E in CFSCR2 of CFHC
are set to 0.
When SCI is enabled, SCI
module pins TXD and RXD
will be available on PR[3:2]
if CA6E and CA5E in
CFSCR2 of CFHC are set
to 0.
General Notes
If the pins are associated with a module which is not enabled, those pins can be served
as general purpose I/O at the voltage of the corresponding power supply rail.
