Ye 1 SY S I F M Solutions for Embedded Systems Development V1 0 Adapters Leopard 2M Nexus Emulation Board 144QFP 100TQ Ordering code IA144P100TQ 56EL70 Target CPU package QFP100 Original microcontroller in the QFP100 package has no Nexus port which may be a significant drawback during the development and test process Leopard 2M Nexus Emulation Adapter is based on the SPC56EL70 microcontroller in the LOFP144 package emulation device which also exposes 4 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 iSYSTEM January 2014 1 6 All 100 pins of the emulated target microcontroller are accessible around the 144 pin emulation device When certain target microcontroller signal needs to be inspected e g by an oscilloscope below description helps locating it Pin 1 marker Spa ae ss m 7s
