1SPC58NH-DISP discovery board
The SPC58NH-DISP discovery board is based on the microcontroller SPC58NH92C5, a high performance
e200z4d triple core 32-bit Power Architecture technology CPU, 200 MHz core frequency with 10496 KB on chip
Flash (10240 KB code Flash + 256 KB data Flash) in an FPBGA386 package.
The several peripherals such as DSPI, LIN (LIN and UART), FlexRay, CAN-FD, two independent ethernet ports
(10/100 Mbps and 1 Gbps), make the SPC58NH-DISP an excellent starter kit for the SW designer to quickly
evaluate the microcontroller as well as to develop and to debug applications.
Free ready-to-run application firmware examples are available inside SPC5Studio web page (http//:www.st.com/
spc5studio) to quickly support evaluation and development.
The PCB, the components and all HW parts assembled in this board meet the requirements of the applicable
RoHS directives.

2.1 Power supply
Figure 1 shows the PSU block diagram.

3.3 V_LR
LD1086D2T50TR 5.0 V_LR
12 V
L5963
3.3 V_SW
The DC input source is 12 V DC: L5963 is used to generate 3.3 V (VDD_HV_xxx), 1.2 V (VDD_LV_xx) and 3.3 V
for ADC section. A linear regulator is used to generate 5 V for ADC.
The LEDs LD2, LD3, LD4, and LD5 are used to check the output of each voltage regulator and 12 V input source.
A resettable fuse (F1) protects the application against the overload or short-circuit.

2.2 Microcontroller
2.2.1 JTAG
A standard JTAG connector 14x0.1” is available for programming and debugging.

2.2.2 Reset
Figure 3 shows the reset circuit.
Figure 3. Reset
The reset signal level is driven to low level when:
• VDD_HV is lower than a fixed level. This feature is used to monitor the VDD_HV level and then to reset
the microcontroller when the level is out of specification. This feature allows to set the reset only when the
VDD_HV is stable.
• the pushbutton is pressed (manual reset); the reset pulse width is fixed.

2.3 Ethernet 10/100 Mbps
Section 2.3 shows the ethernet 10-100 Mbps communication channel.
Figure 4. Ethernet 10/100 Mbps
JP15 allows configuring the communication in MII or RMII mode.
The current absorption of this section can be estimated by removing SB7 then applying a low impedance current
meter or a current probe.

2.4 Ethernet 1 Gbps
The ethernet 1 Gbps section is depicted here below.
Figure 5. Ethernet 1 Gbps
The resistors from R85 to R84, from R88 to R91, from R95 to R98 and from R100 to R103 are used to configure
the device.
With SB9 close and SB8 left open, the 1V2_ETH supply voltage is controlled by an integrated LDO and an
external MOSFET. The user can exclude the LDO regulator and connect the 1V2_ETH to the 1.2 V source form
the PSU section setting SB9 open and SB8 close.

2.5 eMMC and μSD
Figure 6 and Figure 7 are showing the eMMC and µSD card reader section respectively.
From the microcontroller, the signals Data 0÷3, CMD, CLK and FBCLK are shared among these sections and this
means only one section can be active at a time.
These signals must be connected to the active section by selecting the jumpers from JP17 to JP22 properly: see
Figure 8.

2.6 Octal SPI
The OctalSPI section is visible in Section 2.6 . In this application the OctalSPI is connected to a HyperFlash and
HyperRAM device.
The microcontroller ports PF[4] and PN[12] are used to drive CS1# and CS2#.

2.8 Flex Ray
Flex Ray section is reported in Section 2.8 ; JP33, JP34 and JP35 allow selecting which channel from the
microcontroller is connected to the transceiver.

2.10 CAN-FD
Three CAN-FD channels with fast transceivers are connected to DB9 connectors. Further 6 + 6 channels are
connected to 2 connectors without transceivers (GPIO level).
