SPC58NG-DISP discovery board
Introduction
The SPC58NG-DISP discovery board is the hardware platform to evaluate and
develop applications with the SPC58NG84E7 microcontroller at a budget price.
This document describes the hardware architecture of the board and how it is
possible to enable specific functions.

SPC58NG-DISP
Figure 1. SPC58NG-DISP
The SPC58NG-DISP discovery board is based on the microcontroller SPC58NG84E7,
a high-performance e200z4d triple-core 32-bit Power Architecture® technology
CPU, 6 MB Flash with HSM cryptography in an eTQFP176 package.
The several interfaces include GPI/O’s, peripherals such as DSPI, LINFlexD
(LIN and UART), FlexRay, M_CAN ISO CAN-FD, and two ethernet ports make the
SPC570S- DISP an excellent starter kit for the customer to quickly evaluate
the microcontroller as well as to develop and debug application.
Free ready-to-run application firmware examples are available inside the
SPC5Studio web page (www.st.com/spc5studio) to
support quick evaluation and development.
The PCB, the components, and all HW parts assembled in this board meet the
requirements of the applicable RoHS directives.

Power supply section
Figure 4 shows the PSU block diagram.
The DC input source is 12 V and the three voltage regulators generate 5 V, 3.3
V and 1.2 V supply voltages.
The LEDs D1, D2, and D3 are used to monitor the output of each voltage
regulator as well as the test points J2, J3, J5, and J13 to allow measuring
the voltage levels 12 V, 5 V, 3.3 V, and 1.2 V respectively.
Power supply – jumper configuration
U2 provides 3.3 V output voltage used to supply the VDD_HV pins. The test
point J5 can be used to monitor the VDD_HV supply voltage level.
The VDD_LV pin can be supplied using an internal regulator and a ballast BJT
or providing the supply by using an external source. In the default
configuration, the jumpers are set to supply VDD_LV with the external source
(U3) The VDD_LV power supply configuration can be easily configured setting
the soldering jumpers as summarized in the table here below.
