Signal Descriptions
The PPC460EX embedded controller is packaged in a 728-ball thermally enhanced plastic ball grid array (TE-
PBGA). The following tables describe the package level pin-out.
In the table Table 9 on page 64, each I/O signal is listed along with a short description of its function. Active-low
signals (for example, RAS) are marked with an overline. Please see Table 5 on page 25 for the pin (ball) number to
which each signal is assigned.
Multiplexed Signals
Some signals are multiplexed on the same pin so that the pin can be used for different functions. In most cases,
the signal names shown in the following table are not accompanied by signal names that might share the same pin.
If you need to know what, if any, signals are multiplexed with a particular signal, look up the name in Table 5 on
page 25. It is expected that in any single application a particular pin will always be programmed to serve the same
function. The flexibility of multiplexing allows a single chip to offer a richer pin selection than would otherwise be
possible.
Note: Signals multiplexed with GPIO default to GPIO receivers and float after reset. Initialization software must
configure the GPIO registers for the desired function as described in the GPIO section of the user’s manual. Any of
these signals requiring a particular state prior to running initialization code must be terminated with pull-ups or
pull-downs.
