Chapter 2
Signal Description
This chapter describes the external device signals, including a table of signal properties, detailed
descriptions of the available signals, and the I/O pin power/ground segmentation.
2.1
Block Diagram
To provide an extensive feature set as well as compatibility between the MPC5500 family of devices, the
majority of balls are assigned multiplexed signal functions.
shows only the signals that are
available on the device. Signal functions that are not available on this device are not shown in the diagram.
Primary signal functions that are not available on the device but are used as pin labels in the Ball Grid
Array (BGA) map are listed in
.
The 324 package has a limited number of balls which affects the following signals and features:
Refer to the last two columns in
for a comparison of available signals on the 324 package
compared to the VertiCal assembly.
NOTE
The Vertical assembly has ball connections for all the
available
signals on
the device.

324 Package
Maximum 24-bit EBI address bus
ADDR[8:31]_GPIO[4:27]; ADDR[8:11] are muxed
as alternate signals with the chip select signals
CS[0:3]_ADDR[8:11]_GPIO[0:3]. ADDR[8:11] is
also muxed with GPIO[4:7], providing four chip
selects
and
24-bit address bits.
ADDR[8:11]_GPIO[4:7] no balls available.
Use CS[0:3]_ADDR[8:11]_GPIO[0:3] to
choose between using chip select signals
or
maximizing the number of output address
signals ADDR[8:31]_GPIO[0:3, 8:31] for a
24-bit EBI address bus.
Maximum 32-bits wide EBI data bus
DATA[0:31]_GPIO[28:59]
16 balls available for a 16-bits wide
DATA[0:15]_GPIO[28:43]. There are no balls
available for DATA[16:31]_GPIO[44:59].
Four EBI write enable/byte enable
WE/BE[0:3]
Only two balls available (WE/BE[0:1])
EBI transfer error acknowledge
TEA_GPIO[71]
No ball available
EBI bus busy
BB signal not available. GPIO is available.
BB_GPIO[72] no ball available
EBI bus grant
BG signal not available GPIO is available.
BG_GPIO[73] no ball available
EQADC Event trigger inputs 0 and 1
ETRIG[0:1]_GPIO[111:112]
No balls available
General Purpose Input/output
GPIO[205]
No ball available
Calibration bus
Calibration bus is separate from the EBI but uses
the EBI controller. Refer to
for the
calibration bus signals.
No balls availables. These signals are only
available in the VertiCal assembly.
