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 including 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 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.

3Hardware overview
Figure 3. SPC58NG-DISP: HW overview
3.1 Power supply section
The 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.

3.1.1 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.
