STMicroelectronics SPC574S-DISP

Overview

SPC574S-DISP from STMicroelectronics is a discovery board built around the SPC574S64E3 32-bit dual-core e200z4d Power Architecture MCU, featuring 1.5 MB flash, eTQFP100 package, CAN FD (DB9), FlexRay, LIN, and USB virtual COM port for rapid automotive embedded development.

For engineers reviewing the SPC574S-DISP datasheet, SPC574S-DISP pinout, SPC574S-DISP application, or SPC574S-DISP equivalent, this board delivers ASIL-D–compliant evaluation of motor control, safety-critical gateway functions, and multi-protocol vehicle networking with full GPIO access and on-board PLS debugger.

Technical Context

The board implements the SPC574S64E3 microcontroller - dual e200z4d cores with lockstep capability, 1.5 MB on-chip flash, 192 KB SRAM, and integrated safety mechanisms compliant with ISO 26262 ASIL-D. It supports concurrent real-time execution and hardware-based fault detection.

Connectivity includes one CAN FD channel (with DB9 connector), one FlexRay node (with transceiver), one LIN interface, JTAG (7×2 male 0.1" header), and USB-based virtual COM port for host communication and firmware updates.

FAQ

What software tools are required to develop on the SPC574S-DISP?

SPC5 Studio - ST's Eclipse-based IDE - is mandatory and freely downloadable. It includes SPC574S64E3 device support, GCC-based toolchain, HAL libraries, and prebuilt firmware examples. PLS Universal Debug Engine software is also required for on-board debugging and is provided free with code-size-limited evaluation license.

Does the board support standalone operation without a host PC?

Yes. Demonstration firmware is preloaded in the MCU flash memory, enabling immediate stand-alone operation. The board boots and runs motor control or communication demos using its 3 user LEDs, push buttons, and potentiometers - no host connection needed after initial power-up.

How is functional safety supported on this discovery board?

The SPC574S-DISP inherits the SPC574S64E3's hardware safety features: lockstep dual cores, memory ECC, BIST, and safety monitor peripherals. It enables validation of ASIL-D software partitions, fault injection testing, and safety library integration - all aligned with ISO 26262 Part 6 workflows.

Can I connect custom hardware to the 4×40 pin header?

Yes. The 4×40, 0.1" pitch pin grid array provides full access to all MCU GPIOs, power rails, clocks, and debug signals. Pin assignments match the eTQFP100 package mapping and are documented in DB3999 Rev 2, enabling direct interfacing with custom carrier boards, sensor modules, or power stages.
