Introduction

The SPC58NH-DISP discovery board is a standalone hardware platform to evaluate and develop applications with the

SPC58NH92C5, packaged in a FPBGA386 microcontroller at budget price.

This document provides information about the hardware architecture and how to configure the jumpers to enable specific

functions.

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.

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.

Figure 2. JTAG

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).
