Page 7: Hardware Description
2 Hardware Description The TWR-MCF51JG is a Tower Controller Module featuring the MCF51JG256—a ColdFire+ based microcontroller with USB 2.0 full-speed OTG controllers in a 44 MAPLGA package. It is intended for use in the Freescale Tower System but can operate stand-alone. An on-board debug circuit, OSBDM, provides a BDM interface and a power supply input through a single USB mini B connector. -

Page 9: System Power
Figure 5. 32 KHz Oscillator Input 2.3 System Power When installed into a Tower System, the TWR-MCF51JG can be powered from either an on-board source or from another source in the assembled Tower System. In stand-alone operation, the main power source for the TWR-MCF51JG module is derived from the 5.0V input from either the OSBDM USB mini-B connector (J14), the MCF51JG USB micro-AB connector (J8), or the EzPort header (J16) - Page 10 Power from the Tower Primary Connector USB device interface supplied to the MCF51JG on-chip regulator. Power from the MCF51JG USB device interface (J8) supplied to the on-board voltage regulators. TWRMCF51JGUM TWR-MCF51JG Tower Module User's Manual Page 10 of 21...

Page 13: Debug Interface
2.4 Debug Interface There are two debug interface options provided: the on-board OSBDM circuit and an external Background Debug Mode (BDM) connector. The BDM connector is a standard 6-pin connector providing an external debugger cable with access to the BDM interface of the MCF51JG256. Alternatively, the on-board OSBDM debug interface can be used to access the debug interface of the MCF51JG256. -
