SPC574K-DISP Discovery Board

Introduction

The SPC574K-DISP discovery+ board is a development discovery board to evaluate and to develop applications with the microcontroller SPC574K72E5 package at budget price.

The discovery board is based on the microcontroller SPC574K72E5 in eTQFP 144 pin package, a device with three processor cores, two main 32-bit Power Architecture® VLE compliant CPU cores (e200z4), dual issue, running in lockstep and one 32-bit Power Architecture VLE compliant I/O processor core (e200z2).

The SPC574K72E5 is a microcontroller targeted at automotive powertrain controller applications chassis, control applications, transmission control applications, steering and braking applications, as well as hybrid applications.

More information about the microcontroller is reported in the datasheet (DS9223), and in the Reference Manual (RM0334) (see Section B.1: Document references).

This document describes the hardware architecture and in what manner configuring the jumpers is possible to enable specific functions.

Figure 1. SPC574K-DISP - top view

The several interfaces including GPI/O's, 12-bit SAR analog converter, peripherals such as DSPI, LINFlexD (LIN and UART), FlexRay, Ethernet controller and JTAG port make the SPC574K-DISP an excellent starter kit for the customer to quick evaluate the microcontroller as well as to develop and to debug application.

An integrated programmer debugger allows the debugging and programming the microcontroller. The same section allows enabling a USB Virtual COM port.

Dedicated connectors allow plugging shields Arduino UNO R3-compatible. This feature makes it easier to expand the functionality of the SPC574K-DISP with a wide variety of shields and boards available on the market.

2 Hardware overview

2.1 Power Supply section

The input voltage level is 12VDC.

The main regulator is a buck converter based on the device A7985A (Figure 2); it is used to generate 5V. A linear regulator (LD1117S33TR, see Figure 3) generates 3.3 V.

Three LEDs D12, D13 and D14 provide the feedback about the status of the power supply section.

2.2 Microcontroller power management

A jumper plugged in the P13 (3 male pins) allows selecting t the VDD_JTAG voltage level as well as the VDD_CPU source is set with a jumper in P7.

A DC mA-meter connected in place of JP5 allows measuring the current of VDD_HV_IO supply

Figure 5. Microcontroller power management

2.3 Integrated Programmer/Debugger

The board includes an integrated programmer/debugger; it allows the user to program the microcontroller, to build and to debug the software applications. The debugger works with the UDE PLS software.

The SPC574K-DISP discovery board includes a full-featured, perpetual code-limited PLS software license (256 kBytes).

The debugger serial number is reported on the label applied on the PCB (bottom side).

The integrated debugger SW is accessible via ST's free integrated development environment, SPC5Studio (www.st.com/spc5studio). To download the debugger software and to activate license refer to the PLS website.

The core of the debugger is a single chip USB to dual serial / parallel ports. A portion of the device is used to manage the JTAG signals and the second part is used to implement a UART communication channel; some level shifters are used to equalize the signal amplitude.

The supply comes from PC through the USB cable and a 3.3V linear regulator supplies the IC.

The microcontroller can be the programmed and debugged also by using external tools connected to a JTAG port. The resistor array R66 and R68 allows disconnecting the JTAG signal from the integrated debugger(a).

The SPC574K-DISP board comes with the integrated programmer enabled.

a. If the USB cable is not connected to a PC, the integrated debugger will not be supplied. Under this condition an external debugger could not be able to work properly, it is necessary to remove the resistor arrays R66 and R68. It is suggested to perform some tests before removing R66 and R68.

2.4 Crystal oscillator

Figure 10 shows the external oscillator circuit; the frequency is 40MHz.

2.5 Reset circuit

The core of the reset circuit is the device STM6315.

DocID030124 Rev 1 11/32

The U22 asserts a reset signal whenever the VCC pin drops below a fixed value (2.63V) and keeping it asserted until VCC has risen above the threshold for a minimum period of time (210ms).

The device provides also a reset signal when the push-button is pressed.

The reset output is an open drain pin and it must be pulled up to VDD_CPU voltage level (R63).

The LED D3 provides a visual feedback and it is switched on when the reset pulse is generated.

Figure 11. Reset circuit

2.6 FlexRay

Two FlexRay channels are available; the HW configuration is the same for both channels (see Figure 12).

Jumpers JP11-JP 12 and JP13-JP14 are used to connect the load terminations (47Ω). The pin arrays P3 and P5 allow to configure the transceivers plugging jumpers.

In Table 1 summarizes the information about the transceiver signals and the microcontroller ports for both the channels.

2.7 Ethernet.

Figure 13 shows the Ethernet section; the resistors R14, R15, R16 and R17 are the load termination.

The jumpers in P14 (2x10 male pins) enable the signals from the microcontroller to drive the transceiver (see Figure 14 and Table 2).

RJ1 is a RJ45 connector, Figure 15 shows the internal schematic diagram.

Note: The transceiver supply voltage is 3.3 v; the microcontroller supply level must be set consequently.
