POWER
The DEMO9S12XHY256 may be powered from several sources. An option header allows
selection between the various power inputs. For application development and debug, the
board may be powered from the USB BDM. The 2.0mm, center-positive, barrel connector
supports stand-alone operation and higher power requirements. Power may also be applied to
connector J1 or the board may be configured to supply power from connector J1 to external
circuitry. Use J1-1 and J1-3 to connect power to or source power from the demo board.
Use of LIN circuitry requires application of +12V at the barrel connector (J11) or though the LIN
connector. Power applied at the LIN connector provides input to the on-board regulator and is
selected in a similar manner as the barrel connector input.
CAUTION:
Damage to the board may result if voltages greater than +5.0V are
applied at the connector J1 input.
Power Select
Power may be applied to the board through the integrated USB-BDM circuitry, a 2.0mm barrel
connector, or through connector J1. Power selection is achieved using 2 selection headers:
the PWR_SEL (JP9) option header and the VX_EN (JP10) option header.
PWR_SEL
The PWR_SEL option header (JP9) allows the user to select power input either from an
external power source connected to the VIN connector or from the integrated USB-BDM. If
using an external power source, input voltage should fall between +7V and +35V. However,
external input voltage should be kept as low as possible to prevent the voltage regulator from
becoming excessively hot. Figure 3 below details the PWR_SEL (JP9) header connections.
