"Leopard" Nexus Emulation Board 257BGA – 100TQ
Ordering code
IA257BGA100TQ-564XL
Target CPU package: QFP100
Original microcontroller in the QFP100 package has no Nexus port at all which may be a
significant drawback during the development and test process.
"Leopard" Nexus Emulation Adapter is based on the MPC5643L microcontroller in the
BGA257 package (emulation device), which also exposes 12-bit Nexus port. The Emulation
Adapter exhibits the same behaviour to the target as the original 100-pin microcontroller and
additionally provides the Nexus port, which allows advanced functionalities like trace,
profiler and code coverage.
A 100-pin solder part, which must be ordered separately under the IA100TQ-SOLDER
ordering code, is soldered to the target (PCB) instead of populating the original
microcontroller in a 100-pin QFP package. Then the Emulation Adapter, which acts as the
original microcontroller and additionally provides debug Nexus port, is connected on top.
Contact iSYSTEM sales representative for more details on available Nexus tools.
