1Overview
The several interfaces including Ethernet controller, CAN-FD, FlexRay, LIN and UART, ADC, and JTAG port
make the SPC58EC-DISP an excellent tool to evaluate the microcontroller as well as to develop and then debug
applications.
An integrated programmer debugger (supported PLS) allows 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 simple to
expand the board functionality adding a shield or board available on the market. All GPIOs and main signals
are accessible by a 4x37 0.1” pin array.

4.2 Microcontroller power management
The JP34 allows selecting the voltage level to supply VDD_HV_IO_main (5 V or 3.3 V); as well as JP35 sets the
VDD_HV_IO_Flex level. The JP36 sets the VDD_HV_ADC supply level; JP37 sets the 3.3 V source (from linear
or switching regulator). These jumpers allow the evaluation of the current absorption.
The LEDs D5, D6, D7 and D8 provide feedback about the status of the power supply section.

4.3 Integrated programmer/debugger
The integrated programmer/debugger allows the user to program the microcontroller, build, and debug the
software applications. The debugger works with the UDE PLS software.
The debugger serial number is a 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 activate the 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 manages the
JTAG signals while the second part implements a UART communication channel; the level shifters are necessary
to balance the signals levels (3.3 V↔5 V).
The supply comes from the PC through the USB cable and a dedicated 3.3 V linear regulator supplies this
section.
The microcontroller can be programmed and debugged also by using external tools connected to a JTAG port
(2x7 pin). The solder jumper from SB8 to SB14 allows disconnecting the JTAG signal from the integrated
debugger.
Note: An external debugger must be used with the USB cable disconnected and under this working condition; the
integrated debugger is not supplied. If the external programmer does not work properly, the jumpers SB8÷SB14
must be removed (open). It is suggested to perform some tests before removing the jumpers SB8÷SB14.
The SPC58EC-DISP comes with the integrated programmer enabled (all solder jumpers from SB8 to SB14 are
present).

4.4 Crystal oscillator and reset
The Figure 6 shows the external oscillator circuit; the frequency is 40 MHz.
By setting SB2, SB3 (open) and SB3 (closed) it is possible to drive the EXTAL pin with an external clock.

The reset circuit is the device STM6315.
The STM6315 (see Figure 7) asserts a reset signal whenever the VCC pin drops below 2.63 V and keep it
asserted until the level of VCC has risen above the threshold for a 210 ms.

The device generates a reset signal when the SW1 button is pressed.
The reset output is an open drain pin and it must be pulled-up to VDD_CPU voltage level (R69). The LD4
provides feedback when the reset pulse is generated.
4.5 FlexRay
The Figure 8 shows the FlexRay section (transceiver + DB9 connector).
The jumpers JP27 and JP32 connect the load terminations (47 Ω). The jumpers from JP28 to JP31 allow
configuring the transceiver.

4.7 CAN and ISO CAN-FD
Two CAN channels are available, both are based on a fast transceiver; the implemented solution is compatible
with the CAN-FD operation standard.
The jumper JP2 allows the selection in normal o standby mode:
• No jumper: normal operation(1)
• Jumper 2-3: device in standby mode (manual or fixed selection)
• Jumper 1-2: microcontroller drives the standby (dynamic configuration)
• Jumper JP1 enables the load termination
1. In the transceiver, an internal pull-up resistor is already present and R1 could be removed.
4.8 Ethernet
JP5 allows connecting the Ethernet transceiver to the microcontroller to implement RII or MII communication
protocol.
JP5 allows the implementation of another feature: its pins allow plugging an addition board to evaluate the
communication performance by using a different Ethernet physical layer.
The R29 ÷ R32 are the load termination resistors.
Note: The level of the transceiver in/out pins is 3.3 V then the microcontroller supply level must be set consequently.
4.9 User interface (pushbuttons, LEDs and trimmers)
In the board three LEDs and three push-buttons are present and they are suitable for user purposes (see
Figure 11).
