STMicroelectronics SPC560PADPT100S

Overview

SPC560PADPT100S from STMicroelectronics is a mini evaluation module designed for the SPC560P44L3 and SPC560P50L3 automotive microcontrollers in 100-pin LQFP packages. It interfaces with the SPC56XXMB motherboard to provide full access to CPU I/O, dual CAN (HS + LS/FT), dual LIN, SCI, FlexRay, user buttons/LEDs, analog potentiometer input, and configurable 3.3 V/5 V logic levels.

For engineers reviewing the SPC560PADPT100S datasheet, SPC560PADPT100S pinout, SPC560PADPT100S application, or SPC560PADPT100S equivalent, this board enables rapid validation of SPC560Pxx MCU peripheral integration-including CAN FD-capable transceivers, LIN physical layer timing, FlexRay channel arbitration, and mixed-voltage I/O interfacing-within automotive ECU development workflows.

Technical Context

The SPC560PADPT100S serves as a daughter card that mates with the SPC56XXMB motherboard, forming a complete modular evaluation system. It routes all 100 pins of the target SPC560P44L3/L50L3 MCU to expansion headers and provides dedicated jumpers to select logic voltage (3.3 V or 5 V) per peripheral group.

Onboard power regulation uses the ST L9758 to generate three clean rails: 1.2 V for core, 3.3 V for I/O, and 5 V for legacy peripherals. Dual CAN channels are implemented with selectable High-Speed (ISO 11898-2) and Low-Speed Fault-Tolerant (ISO 11898-3) transceivers via hardware jumpers, each terminating to DB9 male connectors.

FAQ

Does the SPC560PADPT100S include the SPC560P microcontroller?

No. The SPC560PADPT100S is a carrier board only - the SPC560P44L3 or SPC560P50L3 MCU must be purchased separately and soldered onto the module. This design allows users to evaluate multiple MCUs using the same board and motherboard combination.

What is the role of the L9758 voltage regulator on this board?

The STMicroelectronics L9758 provides three synchronized, low-noise output rails: 1.2 V (core), 3.3 V (I/O), and 5 V (legacy peripherals). Its integrated watchdog and reset generation support automotive-grade power sequencing and fault monitoring requirements.

Can both CAN channels operate simultaneously, and what transceivers are used?

Yes - both CAN channels can operate concurrently. Channel 1 uses a fixed High-Speed transceiver (ISO 11898-2). Channel 2 supports jumper-selectable operation between High-Speed and Low-Speed Fault-Tolerant (ISO 11898-3) modes, enabling robust diagnostics and wake-up testing across bus topologies.

How does the logic level configuration affect peripheral compatibility?

Jumper settings determine whether CAN, LIN, SCI, and FlexRay transceivers operate at 3.3 V or 5 V I/O levels. This ensures safe interoperability with legacy 5 V ECUs or modern 3.3 V sensors and actuators without level-shifting circuitry.
