STMicroelectronics SPC572L-DISP

Overview

SPC572L-DISP from STMicroelectronics is a Discovery+ evaluation board built around the SPC572L64E3 32-bit Power Architecture® VLE-compliant MCU featuring 1568 KB RWW flash, 64 KB SRAM, SMPU, and integrated CAN/KLine/USB virtual COM interfaces. It supports EEPROM emulation (32 KB) and provides full peripheral access via 4×37 pin headers for rapid automotive microcontroller prototyping.

For engineers reviewing the SPC572L-DISP datasheet, SPC572L-DISP pinout, SPC572L-DISP application, or SPC572L-DISP equivalent, this board delivers validated debug infrastructure (PLS debugger), dual JTAG connectors (2×7 0.1" and 2×5 0.05"), 20 MHz crystal timing, and preloaded firmware for stand-alone demonstration - all targeting automotive ECU development workflows.

Technical Context

The board implements the SPC572L64E3 MCU in a production-representative configuration with system-level peripherals directly accessible: one high-speed CAN 2.0B port with transceiver, one KLine (ISO 9141-2) interface with transceiver, and USB virtual COM for host communication. All are electrically isolated and routed to standard headers.

It integrates two JTAG debug interfaces - a standard 7×2 male 0.1" connector and a mini 2×5 0.05" connector - both compatible with PLS UDE software, which includes a perpetual 256 KB debugging/programming license. The board operates from either 12 V external supply or USB power.

FAQ

Does the SPC572L-DISP include on-board debugging hardware?

Yes. The board integrates a PLS-compatible on-board debugger-programmer, eliminating the need for external debug probes. It supports full SWD/JTAG-based programming and real-time debugging via UDE software, with a perpetual 256 KB license included for code download and trace.

What software tools are required to use the SPC572L-DISP?

SPC5Studio - ST's free IDE - is mandatory for configuration, code generation, and firmware deployment. It includes BSP, startup routines, interrupt handlers, and visual peripheral configurators. UDE from PLS is required for advanced debugging; its 256 KB license is bundled with the board.

Can the SPC572L-DISP operate without an external power supply?

Yes. The board can be powered solely via USB (5 V) for low-power operation and basic debugging. However, full peripheral functionality - especially CAN and KLine transceivers - requires the 12 V external supply to meet voltage and current specifications per ISO 11898 and ISO 9141-2 standards.

Are firmware examples preloaded on the SPC572L-DISP?

Yes. The SPC572L64E3 MCU ships with demonstration firmware preloaded in flash memory, enabling immediate stand-alone operation to verify CAN message transmission, LED control, and UART echo without host PC setup or toolchain installation.
