MC56F80000-EVK Board User Manual
The OpenSDA circuit is based on the NXP Kinetis K26 family microcontroller
(MK26FN2M0VMI18) with 2 MB of embedded flash and an integrated USB controller.
OpenSDA comes preloaded with the firmware, which provides a debug protocol interface
and a virtual serial port interface.
The OpenSDA circuit provides a JTAG debug interface to MC56F80748. A standard USB
A male to micro B male cable is used for debugging via the USB connector (J12).
USB drivers for this onboard OpenSDA circuit are available in the host PC once the latest
CodeWarrior IDE or any P&E tools that support DSC have been installed.
For details about the JTAG connector, see
The following table describes the OpenSDA signals connected to the target MCU
(MC56F80748).

2.9 Input/output headers
The MC56F80748 microcontroller is packaged in a 64-pin QFP package. Some pins
are utilized in onboard circuitry, however, many are directly connected to one of four I/O
headers (J1, J2, J3, and J4), which are also compatible with Arduino R3 pin layout.
The following tables describe the MC56F80000-EVK Arduino connectors pinout.
