STMicroelectronics SPC570SADPT100S

Overview

SPC570SADPT100S from STMicroelectronics is a daughter card for evaluating the SPC570Sx 32-bit automotive microcontrollers in eTQFP100 package. It provides full access to CPU I/O signals, dual CAN-FD channels, two FlexRay channels, LINFlexD interface, RS232/SCI, and Nexus 3+ debug via Mictor connector, supporting comprehensive functional validation in automotive ECU development.

For engineers reviewing the SPC570SADPT100S datasheet, SPC570SADPT100S pinout, SPC570SADPT100S application, or SPC570SADPT100S equivalent, this board enables rapid prototyping of powertrain control units, body domain controllers, and chassis safety systems requiring multi-protocol connectivity and high-fidelity trace debugging.

Technical Context

The SPC570SADPT100S interfaces exclusively with the SPC58XXMB/SPC57XXMB motherboard to form a complete modular evaluation system. It supports standalone use when only MCU socket-level access is required, without peripheral interfacing.

It delivers regulated 5.0 V, 3.3 V, and 1.25 V switching supplies plus a dedicated 5 V linear regulator for ADC references, and routes all MCU signals to port-ordered 0.1" headers, two 240-way expansion connectors, and standardized physical interfaces including DB9 (CAN-FD, FlexRay, RS232), Mictor (Nexus 3+), and SMA (external clock input).

FAQ

Is the SPC570Sx microcontroller included with the SPC570SADPT100S daughter card?

No. The SPC570SADPT100S is a socketed daughter card only - the SPC570Sx MCU must be purchased separately. The open-top socket accommodates eTQFP100-packaged devices, and ST recommends verifying pin compatibility and thermal requirements before insertion.

What motherboard is required to use the SPC570SADPT100S?

The SPC570SADPT100S requires either the SPC58XXMB or SPC57XXMB motherboard to operate as a full evaluation system. These motherboards provide power distribution, host interface logic, and peripheral bridging; the daughter card alone supports only basic socket access and reset monitoring.

Does the SPC570SADPT100S support Nexus Level 3+ trace debugging?

Yes. It features a 38-pin Mictor connector wired for Nexus Level 3+ debug and trace, enabling instruction trace, data trace, and real-time variable monitoring when used with compatible debug probes such as Lauterbach TRACE32 or iSystem winIDEA.

Can the SPC570SADPT100S be used without the motherboard?

Yes - it can operate standalone for basic MCU socket testing, reset verification, and clock signal injection. However, all communication interfaces (CAN-FD, FlexRay, LIN, SCI), power regulation, and debug capabilities require connection to the SPC58XXMB/SPC57XXMB motherboard.
