+5V Power Supply Connection

The MPC8XXFADS requires +5 Vdc @ 5 A max, power supply for operation. Connect the +5V power

supply to connector P6 as shown below:

FIGURE 2-7 P6: +5V Power Connector

P6 is a 3 terminal block power connector with power plug. The plug is designed to accept 14 to 22

AWG wires. It is recommended to use 14 to 18 AWG wires. To provide solid ground, two Gnd

terminals are supplied. It is recommended to connect both Gnd wires to the common of the power

supply, while VCC is connected with a single wire.

NOTE

Since hardware applications may be connected to the

MPC8XXFADS via the Daughter-Boards’ expansion

connectors PX1, PX2 PX3, PX4 or FADS’s P8, the

additional power consumption should be taken into

consideration when a power supply is connected to the

MPC8XXFADS.

P7: +12V Power Supply Connection

The MPC8XXFADS requires +12 Vdc @ 1 A max, power supply for the PCMCIA channel Flash

programming capability or for 12V programmable Flash SIMM. The MPC8XXFADS can work properly

without the +12V power supply, if there is no need to program either a 12V programmable PCMCIA

flash card or a 12V programmable Flash SIMM.

Connect the +12V power supply to connector P7 as shown below:
