Preliminary Data Sheet
Pin Group List
The following table provides a summary of the number of package pins (balls) associated with each functional
interface group.
In the table “Signal Functional Description” on page 38, each external signal is listed along with a short description
of the signal function. Active-low signals (for example, Halt) are marked with an overline. See the preceding table,
“Signals Listed Alphabetically” on page 17, for the pin (ball) number to which each signal is assigned.
Shared Pins
Some signals are shared on the same package pin so that the pin can be used for different functions. In most
cases, the signal names shown in this table are not accompanied by signal names that might share the same pin.
If you need to know what, if any, signals are shared with a particular signal, look up the name in “Signals Listed
Alphabetically” on page 17. It is expected that in any single application a particular pin will always be programmed
to serve the same function. The flexibility of sharing allows a single chip to offer a richer pin selection than would
otherwise be possible.
Initialization Strapping
One group of pins is used as strapped inputs during system reset. These pins function as strapped inputs only
during reset and are used for other functions during normal operation (see “Initialization” on page 65). Note that the
use of these pins for strapping is not considered multiplexing since the strapping function is not programmable.
Pull-Up and Pull-Down Resistors
Pull-up and pull-down resistors are used for strapping during reset and to retain unused or undriven inputs in an
appropriate state. The recommended pull-up value of 3k
Ω
to +3.3V and pull-down value of 1k
Ω
to GND, applies
only to individually terminated signals. To prevent possible damage to the device, I/Os capable of becoming
outputs
must never
be tied together and terminated through a common resistor.
If your system-level test methodology permits, input-only signals can be connected together and terminated
through either a common resistor or directly to +3.3V or GND. When a resistor is used, its value must ensure that
the grouped I/Os reach a valid logical zero or logical one state when accounting for the total input current into the
PPC405EX.
