MPC560xP devices
1 Introduction
The MPC560xP microcontrollers are members of the 32-bit
Qorivva microcontroller family built on the Power
Architecture® technology. The devices are targeted at the
chassis and safety market segment, especially the Electrical
Hydraulic Power Steering, low end Electrical Power Steering
and Airbag applications.
The purpose of this document is to describe hardware design
considerations when developing hardware for the MPC560xP
family of microcontrollers: 5604P, 5603P, 5602P, 5601P. It
will cover topics such as clock generation, decoupling,
Voltage regulator and power considerations. Detailed
reference design schematics and descriptions of the main
components are also contained within this document. Some
general hardware recommendations are also provided.
2 Power Supply
The MPC5604P has a single main/input voltage supply which
can be either 5 V or 3.3 V with a specified tolerance of ±10%
this is converted using the internal VREG to 1.2V ±10% for
the core logic. The user is not permitted to supply the core
logic via an external 1.2 V supply, they must always use the
on-chip voltage regulator (VREG).

    2.1 Voltage Regulator The voltage regulator on the MPC560xP converts the main input supply 3.3 V or 5.0 V ±10% to 1.2 V core logic level. The internal voltage regulator requires an external capacitance to be connected to the device in order to provide a stable 1.2 V low voltage digital supply to the device.

    Minimum external circuitry 7 Minimum external circuitry In general, other than the connector, no additional circuitry is required for the Nexus/JTAG debug circuitry. The MPC5600 devices include internal pull devices that ensure the pins remain in a safe state; however, if there is additional circuitry connected to the Nexus/JTAG pins, or long traces that could be affected by other signals (due to crosstalk from high-current or high-speed signals), a minimum number of external pull resistors can be added to insure proper operation under all conditions.

    Example communication peripheral connections 8 Example communication peripheral connections There are a wide range of peripheral pins available on the MCU. Many of these have fairly standard definitions for their use. This section provides example connections for some of the most commonly used communications peripherals, such as LIN, CAN, Ethernet, and RS-232 communication interfaces.
  • Page 16 Example communication peripheral connections Figure 8 shows the typical connections between the serial port of an MCU and the MAX3232-EP RS-232D transceiver from Texas Instruments (http://www.ti.com/ ). The transceiver operates from either a 3.3-V or a 5-V supply and includes two charge pumps to generate the required output voltages.
