UM2740 User manual SPC58XXMB evaluation board Introduction This document describes the STMicroelectronics SPC58XXMB evaluation board. Figure 1. SPC58XXMB UM2740 - Rev 1 - January 2021 www.st.com For further information contact your local STMicroelectronics sales office.
Overview Overview This user’s manual details the setup and configuration of the STMicroelectronics SPC58XXMB evaluation board (hereafter referred to as the EVB). The EVB is intended to provide a mechanism for easy customer evaluation of the SPC58xx family and SPC57xx family of microcontrollers, and to facilitate hardware and software development.
Attention: This evaluation board only offers limited features for evaluating ST products. It has not been tested for use with other products and is not suitable for any safety or other commercial or consumer application. This evaluation board is otherwise provided “AS IS”...
UM2740 Handling precautions Handling precautions Please take care to handle the package contents in a manner such as to prevent electrostatic discharge. Before the EVB is used or power is applied, please fully read the following sections on how to correctly configure the board.
UM2740 Hardware description Hardware description List of acronyms The table below provides a list and description of acronyms used throughout this document. Table 1. List of acronyms Acronym Description 1.25V_SR Supply voltage from the 1.25 V switching regulator 3.3V_SR Supply voltage from the 3.3 V switching regulator 5V_LR Supply voltage from the 5.0 V linear regulator 5V_SR...
UM2740 Modular concept Modular concept For maximum flexibility and simplicity, the EVB has been designed as a modular development platform. The EVB main board does not contain an MCU. Instead, the MCU is fitted to an MCU daughter card (occasionally referred to as an adapter board).
UM2740 EVB features EVB features The EVB system consists of a motherboard and a daughter card, both with distinct features. The mother board provides the following key features: • Support provided for different SPC58xx MCUs and SPC57xx MCUs by utilizing MCU daughter cards •...
UM2740 Configuration Configuration This section details the configuration of each of the EVB functional blocks. The EVB has been designed keeping in mind the ease of use, and has been segmented into functional blocks as shown in the figure below. A detailed silkscreen legend has been used throughout the board to identify all switches, jumpers and user connectors.
UM2740 Power supply configuration Power supply configuration The EVB requires an external power supply voltage of 12 V DC, minimum 1 A. This allows the EVB to be easily used in a vehicle if required. The single input voltage is regulated on-board using three switching regulators to provide the necessary EVB and MCU operating voltages of 5.0 V, 3.3 V and 1.25 V, and one 5 V linear regulator for the ADC supplies and references.
UM2740 Regulator power jumpers Regulator power jumpers There are four power regulator circuits on the SPC58xx motherboard that supply the required voltages to operate the MCUs: • 1.25V_SR: 1.25 V switching regulator to supply the core voltage • 5V_SR: 5 V switching regulator to supply the power management controller, I/O and peripherals •...
UM2740 CAN configuration 4.11 CAN configuration The EVB has two high speed CAN FD transceivers and two female standard DB9 connectors to provide physical CAN FD interfaces for the MCU. The pinout of the DB9 female connector (J5) is shown in the below figure. Figure 6.

LIN control jumpers Jumper Label Description LIN_EN LIN PHY (U50) enable LIN_RX LIN RX enable LIN_TX LIN TX enable 4.14 FlexRAY configuration The EVB is fitted with two FlexRAY transceivers, a female DB9 connector (for both transceivers) and two alternative connectors.
UM2740 Ethernet configuration 4.15 Ethernet configuration The EVB is fitted with a standard RJ45 Ethernet connector (J7) and an Ethernet transceiver (U6). By default, the Ethernet interface is not enabled. To enable the Ethernet interface the jumpers detailed in Table 5. LIN control jumpers need to be placed.
UM2740 Motherboard test points 4.16 Motherboard test points Several test points of different shapes and functionalities are scattered around the EVB to allow an easy access to MCU and reference signals. This chapter summarizes and describes the available test points. Motherboard test points are listed and detailed in the below table.
UM2740 Board interface connectors 4.17 Board interface connectors This chapter provides a useful cross reference to see the connection from the motherboard to the board interface connector, and what MCU pins are connected to the interface connector on the daughter cards. Table 7.
