The integrated debugger provides power and ground to the target, thereby eliminating the
need to power the board externally. Power from the integrated USB BDM is derived from the
USB bus; therefore, current consumption is limited by the USB specification. Total current
consumption for the target board, and any connected circuitry, must not exceed 350 mA. Ex-
cessive current drain will violate the USB specification causing the bus to disconnect. This will
force a target POR.
The integrated USB BDM provides a virtual COM port for serial communication applications.
The BMD also provides virtual instrument analyzer function. Refer to the P&E Micro Demo
Toolkit for details.
BDM Port Connector
As standard 6-pin BDM connector is also provide to allow use of external BDM cables capable
of supporting the MCF51AC26 or MC9S08AC128/60/16 devices.

POWER
The DEMOAC may be powered from the integrated USB BDM, an on-board voltage regulator,
or from the MCU connector at J1. Alternatively, the DEMOAC may be configured to provide
power to external circuitry connected to the MCU connect J1.
The PWRSW power switch controls input voltage to the board regardless of input voltage
source.
External Power
The power jack at POWER allows the board to be powered from an externally connected
power source. This connection accepts a standard 2.1mm, center-positive, barrel plug con-
nector. +VIN should fall between +7VDC and +18VDC. Input voltage applied to the barrel
connector should be kept as lows as possible to minimize device heating.
CAUTION: Violating the USB specification will cause the USB bus to disconnect forcing the
