STMicroelectronics SPC58XXMB

Overview

SPC58XXMB from STMicroelectronics is a modular motherboard for evaluating 32-bit automotive microcontrollers in the SPC58x and SPC57x families, supporting full CPU signal access, dual CAN FD (DB9), FlexRay (dual channel, DB9 + alternatives), LINFlexD, RS232/SCI, and 10/100 Ethernet (RJ45) interfaces.

For engineers reviewing the SPC58XXMB datasheet, SPC58XXMB pinout, SPC58XXMB application, or SPC58XXMB equivalent, this evaluation platform enables hardware validation of automotive MCU peripherals including high-speed serial buses, analog input (potentiometer), user I/O (4 switches/LEDs), and multi-rail power delivery (5.0 V, 3.3 V, 1.25 V switching + 5 V linear).

Technical Context

The SPC58XXMB serves as a carrier platform-not a standalone IC-designed to host interchangeable daughter cards (e.g., SPC58xxADPT, SPC57xxADPT) that mount specific SPC58x/SPC57x MCUs. It provides system-level signal routing, regulated power domains, and physical interface transceivers aligned with automotive communication standards.

All MCU signals are exposed via port-ordered 0.1" headers and two 240-way high-density expansion connectors. The board integrates four on-board regulators (three switching, one linear), master power control, status LEDs, and dedicated analog conditioning for ADC reference stability.

FAQ

Is the SPC58XXMB a microcontroller or a development board?

No, the SPC58XXMB is a motherboard-only evaluation platform-it does not contain an MCU. It requires a compatible daughter card (e.g., SPC58xxADPT or SPC57xxADPT) to host the target SPC58x or SPC57x microcontroller and enable full functionality.

Which daughter cards are compatible with the SPC58XXMB?

The SPC58XXMB supports ST's standardized daughter card form factor, including SPC58xxADPT (for SPC58x devices) and SPC57xxADPT (for SPC57x devices). All compatible cards use identical 240-pin expansion interfaces and port-mapped signal routing per DB4027.

Does the SPC58XXMB support AUTOSAR-compliant development?

Yes-the board exposes all required hardware resources (CAN FD, FlexRay, Ethernet, LIN, clock sources, and debug interfaces) needed for AUTOSAR OS and BSW layer integration, and is referenced in ST's SPC5 AUTOSAR development kits and configuration tools.

Can the potentiometer and user switches be used for calibration and test automation?

Yes-the onboard 10 kΩ potentiometer feeds directly into the daughter card's ADC input channel, and the four user switches/LEDs are routed to GPIO pins with configurable pull-ups/downs, enabling manual calibration checks and scripted functional test sequences via host PC or embedded test firmware.
