STMicroelectronics SPC56XXMB

Overview

SPC56XXMB from STMicroelectronics is an evaluation motherboard designed to host SPC560xx-series automotive microcontrollers via the SPC56xxxADPT mini module (not included). It provides full access to CPU I/O, dual CAN (HS + LS/FT), dual LIN, SCI, dual FlexRay, 4 user buttons/LEDs, analog potentiometer input, and configurable 3.3 V/5 V logic levels with onboard L9758 regulator delivering 1.2 V, 3.3 V, and 5 V.

For engineers reviewing the SPC56XXMB datasheet, SPC56XXMB pinout, SPC56XXMB application, or SPC56XXMB equivalent, this board serves as a validated hardware platform for functional validation, peripheral interface testing, and firmware development targeting automotive powertrain and chassis control systems.

Technical Context

The SPC56XXMB implements a modular evaluation architecture where the motherboard provides fixed infrastructure-power regulation, transceivers, connectors, and prototyping area-while target MCU functionality is defined by the pluggable SPC56xxxADPT mini module. All communication interfaces (CAN, LIN, SCI, FlexRay) are enabled via jumpers and use industry-standard DB9 or pin-header connectors.

Power management centers on the ST L9758 triple-output regulator, supporting mixed-voltage operation across peripherals and enabling logic-level selection per interface group. The 5.5" × 9.0" PCB includes dedicated expansion headers, a 0.1"-pitch prototyping area with SOIC footprint, and jumper-configurable signal polarity and enable states for all user I/O.

Key Specifications

Availability

FAQ

Is the SPC56XXXADPT mini module included with the SPC56XXMB motherboard?

No. The SPC56XXMB motherboard requires a separate SPC56xxxADPT mini module (e.g., SPC560B50L5ADPT or SPC560P50L5ADPT) to function. The motherboard provides mechanical and electrical support but contains no embedded processor; the mini module hosts the actual SPC560xx MCU and its boot configuration.

What voltage levels can be configured for peripheral interfaces on the SPC56XXMB?

The motherboard supports jumper-selectable 3.3 V or 5 V logic levels for CAN, LIN, SCI, and FlexRay transceivers. This allows direct compatibility testing with both legacy 5 V automotive modules and modern 3.3 V ECUs without external level-shifting circuitry.

Does the SPC56XXMB support fault-tolerant CAN communication?

Yes. One CAN channel is configurable via jumpers to operate in Low-Speed Fault-Tolerant (LS-FT) mode using the integrated transceiver, enabling robust diagnostics and bus-off recovery testing per ISO 11898-3 in degraded network conditions.

Can the SPC56XXMB be used for production deployment?

No. The SPC56XXMB is strictly an evaluation and development tool-not qualified for automotive safety-critical or production environments. It lacks ASIL certification, environmental hardening, and long-term reliability validation required for end-product integration.
