STMicroelectronics SPC572LADPT80S

Overview

SPC572LADPT80S from STMicroelectronics is a daughter card for evaluating the SPC572Lx 32-bit automotive microcontroller in eTQFP80 package. It provides full access to CPU I/O signals, dual CAN-FD channels, LINFlexD, RS232/SCI, Nexus 2 debug interface, and supports external 40 MHz crystal or 8 MHz oscillator clocking. Designed for functional validation of powertrain and body control ECUs.

For engineers reviewing the SPC572LADPT80S datasheet, SPC572LADPT80S pinout, SPC572LADPT80S application, or SPC572LADPT80S equivalent, this board enables rapid prototyping of automotive MCU firmware, hardware interface verification, and real-time debugging via JTAG and Nexus 2 with on-board voltage regulation and signal accessibility.

Technical Context

The SPC572LADPT80S interfaces exclusively with the SPC58XXMB/SPC57XXMB motherboard to form a complete evaluation system. It routes all MCU signals-including 2× CAN-FD, LINFlexD, SCI, and FlexRay-capable I/O-to standardized connectors (14-pin JTAG, 34-pin Nexus 2, 10-pin SIPI) and two 240-way expansion headers.

On-board regulation includes switching supplies at 5.0 V, 3.3 V, and 1.25 V plus a dedicated 5 V linear regulator for ADC references-ensuring noise-sensitive analog subsystems meet automotive-grade stability requirements during functional testing.

FAQ

Is the SPC572Lx MCU included with the SPC572LADPT80S daughter card?

No. The SPC572LADPT80S is a bare evaluation daughter card only-it does not include the SPC572Lx microcontroller. The target MCU must be purchased separately and installed into the open-top socket. This allows users to evaluate multiple SPC572Lx variants without replacing hardware.

What motherboard is required to operate the SPC572LADPT80S?

The SPC572LADPT80S requires either the SPC58XXMB or SPC57XXMB motherboard to function. These motherboards provide power distribution, host interface connectivity (USB-to-JTAG, Ethernet), and peripheral bridging (CAN transceivers, LIN drivers, FlexRay PHY). The daughter card cannot operate standalone for full I/O access.

Does the board support CAN FD physical layer compliance?

Yes. The SPC572LADPT80S integrates two high-speed CAN-FD channels with standard DB9 female connectors and onboard CAN transceivers compliant with ISO 11898-2:2016. Bit rates up to 5 Mbit/s are supported in FD mode when paired with appropriate termination and cabling.

Can the analog potentiometer and user LEDs be re-routed for custom signal injection?

Yes. All four user switches and LEDs, plus the potentiometer, are connected through 0.1" pitch headers with uncommitted routing-enabling direct solder-jumper or wire-wrap reconfiguration to inject test signals, emulate sensor inputs, or monitor internal logic states during ECU software bring-up.
