2.2 MPC5604P Controller Board Architecture

The MPC5604P Controller Board is flexible enough to allow the user to fully exploit the MPC5604P

features to optimize a performance of their product. Its basic building blocks are depicted in Figure 1. The

block color differentiates a block function.

• Blue - MCU and application software download and the debug interface

• Green - Motor control related hardware

• Red - Board power supply and connectivity

• Violet - Application control

Figure 1. MPC5604P Controller Board Block Diagram

The board can be supplied by VBAT voltage in the range of 8V to 18V. The MC33905 provides two

independent voltage sources, one for supplying MCU and second for auxiliary logic. Both sources

provides either 3.3V or 5V, depending on the assembled SBC version.

The UNI-3 expansion interface enables MCU to direct control of the electrical motor or DC/DC

converters.

The Fault logic triggers several important system faults as described in a particular chapter. The circuitry

behavior depends on the selected configuration. For more info, see Section 3, “Interface Description.

The user can control the application using the rotary switch, USB interface (RS232), CAN and LIN buses.

The JTAG/NEXUS interfaces is present on-board to enable download and debugging of MCU code.

The controller board is powered from two independent voltage regulators which provides 5V for a

auxiliary logic and 5V for MCU and debugger logic. Both voltages are generated by the MC33905 SBC

integrated circuit. Proper operation is monitored by LED D114 for the AUX 3.3V line, see Table 2.

The board is designed to operate in the voltage range from 8V to 18V. The board is protected against a

reverse battery.

3.2 UNI3 Interface J300

The UNI-3 interface (connector J300) defines the interface between the MPC5604P Controller Board and

a 3 phase electrical motor power stages.

The list of UNI-3 signals follows:

• Control signals:

— PWM phase A, B, C top and bottom switches control

— Brake signal control

— Power Factor Correction (PFC)

• Monitor signals

— DC-bus current

— Phase A, B, C current

— Zero-cross signals

— Back-EMF phase A, B, C

— Temperature monitoring

• Power Supply 12V

• Serial line - a bidirectional communication line between the Controller Board and Power Stage
