SPC572L-DISP Discovery+ Board
Introduction
This manual provides information for the final user application developer on how to
configure and to use the SPC572L-DISP microcontroller evaluation board.
The discovery board SPC572L-DISP is based on the microcontroller SPC572L64E3, a high
performance 32-bit Power Architecture technology CPU, 1568KB flash in an eTQFP100
package.
The several interfaces including GPIO's, peripherals such as DSPI, LIN, UART, ISO CAN-
FD make the SPC572L-DISP an excellent starter kit for the customer to quickly evaluate the
microcontroller as well as to develop and debug application. An integrated programmer
debugger allows debugging and programming the microcontroller without further tools. The
same circuit allows enabling a USB to serial communication channel (USB Virtual COM
port).
A standard JTAG port allows programming the microcontroller by using different
debug/programmer tools.

2.1 Power supply section
Figure 2. PSU section - DC input
2.1.1 External Power Supply
The external DC supply must be plugged in X2; the switch S1 allows the user to disconnect
the external supply source.
The voltage regulators, U15 and U16 are used to generate 5 V and +3.3V respectively. U14
is a pre-regulator and it must be used when the DC voltage supply is higher than 12 V (i.e.
when the board is used in an application with a DC input higher than 12 V).
The LEDs D7, D9 and D10 are all ON when the board power supply section works properly
and the switch S1 is set to ON position.
2.1.2 USB connection: 3.3 V
If the integrated programmer/debugger is used, 5V from the USB port supplies the board.
U17 and U18 are used to implement an automatic switch.
The VDD_HV_Flex, VDD_HV_JTAG and VDDHV_ADR voltage level is set with the jumper
JP2, JP3 and JP4.
Some test pins are present to monitor the supply voltage levels.

2.2 Crystal oscillator
The external oscillator is connected to a 20MHz crystal (Y2).
2.3 Reset section
U19 drives the reset signal to low level till the VDD_HV_IO level is lower than a fixed level
and it provides a reset pulse when the pushbutton S2 is pressed.
JP21 and JP22 connect the reset signal to the ESR0 and PQRST signal respectively
(default connection: JP21 is closed).
2.4 User LEDs
Three LEDs (D15, D16 and D17) are available for user purposes. The jumpers JP18, JP23
and JP24 allow disconnecting the cathode of each LED's and PE[0], PE[1] and PE[2] can be
used for a different purpose.
2.5 Integrated USB programmer/debugger and JTAG port
The integrated debugger allows the user to program and to debug the software applications.
The integrated tool is based on the UDE PLS software and the device FTDI2232H.
The SPC572L-DISP discovery board includes a full-featured, perpetual code-limited PLS
software license. The debugger serial number is reported on a label applied on the board.
The integrated debugger SW is accessible via SPC5Studio (www.st.com/spc5studio), a
ST's free integrated development environment. To download the debugger software and to
activate the license refer to the PLS website.

Hardware description UM2464
8/11 UM2464 Rev 1
Some jumpers enable the JTAG port. The board with this setup can be programmed by
using an external programmer. By removing RP1, the integrated programmer is
disconnected and the JTAG port will be enabled to program the microcontroller.
Note: If the USB cable is not used and the board is supplied by using an external DC source, it is
suggested to test the external JTAG programmer before removing the resistor array RP1.
2.6 CAN
U24 is the CAN communication transceiver. Different devices can be assembled:
AMIS30663 or MCP2561 and JP14 must be configured properly considering the transceiver
assembled.
The jumper JP15 connects the termination resistor for CAN bus (120 Ω) while TP14 and
TP15 allow monitoring the output signals CANL and CANH respectively.
The CAN Rx and Tx signals are connected to P4.
2.7 FlexRay
The U23 is the transceiver to manage the FlexRay communication; JP10, JP11 and JP12
allow selection between two channels (FlexRay_0_CA and FlexRay_0_CB). The outputs
are connected to P4, pin 3 and 5; TP12 and TP13 allow monitoring the FlexRay output
signals.
2.8 LIN and UART
The LINFlex supports LIN Master mode, LIN Slave mode and UART mode. JP5 and JP6 are
dedicated to select among LIN_0, LIN_1 and K.
U21 is the transceiver to support the LIN communication, whereas U22 is used to support K-
Line.
The output of these two communication channels is connected to the connector P3.
2.9 4x2x25 connector adapter
This is a female pin array used to connect the main board to a small PCB with the
microcontroller.
