STMicroelectronics SPC582B-DIS

Overview

SPC582B-DIS from STMicroelectronics is a Discovery evaluation board built around the SPC582B60E1 32-bit Power Architecture® microcontroller (z2 core, 80 MHz, 1 MB code flash, eQFP64 package), featuring on-board USB-JTAG debugger, Arduino Uno R3 headers, and dual power options (USB 5 V or external 3.3/5/7–12 V). It enables rapid prototyping for automotive body/gateway and industrial control applications requiring ASIL-B functional safety support.

For engineers reviewing the SPC582B-DIS datasheet, SPC582B-DIS pinout, SPC582B-DIS application, or SPC582B-DIS equivalent, this board provides immediate access to all MCU I/O signals, preloaded demonstration firmware, SPC5Studio-integrated GCC toolchain, visual code generation, BSP, and RTOS-ready low-level drivers - all at budget price with Arduino shield compatibility.

Technical Context

The SPC582B-DIS implements full hardware access to the SPC582B60E1 MCU, including all GPIOs, peripheral interfaces (CAN, SPI, UART, I²C), and debug resources via integrated USB-JTAG PLS. Its 40 MHz crystal provides system clock reference for the z2 core's internal PLL, enabling stable 80 MHz operation.

Board-level resources include eight LEDs (3 for debugger status, 3 user-controllable, 1 reset, 1 power), two push buttons (USER and RESET), and dual extension systems: Arduino Uno R3-compliant headers and full-pin breakout headers for probing, expansion modules, and custom prototyping.

FAQ

Does the SPC582B-DIS include preloaded firmware?

Yes. The board ships with demonstration firmware preloaded in the SPC582B60E1's flash memory, enabling immediate stand-alone operation for evaluating core functionality, peripheral interfaces, and safety features without initial toolchain setup.

Is Arduino shield compatibility hardware-native or requires adapter?

Hardware-native. The board integrates Arduino Uno Revision 3 mechanical and electrical pinout directly - no adapter or level-shifting is needed to use standard Arduino shields for sensor, actuator, or communication expansion.

What software tools are required to develop on the SPC582B-DIS?

SPC5Studio is mandatory - it provides the free GCC compiler, visual configuration engine, BSP, startup code, interrupt handlers, and optional free RTOS. Windows OS is required; no third-party IDE license or subscription is needed for basic evaluation and development.

Can the SPC582B-DIS be used for ASIL-B compliance verification?

It supports early-stage ASIL-B development and verification: the underlying SPC582B60E1 MCU includes lockstep cores, ECC RAM/flash, and safety libraries in SPC5Studio. However, final compliance requires full qualification per ISO 26262 Part 6 using certified toolchains and documentation - not provided on the board itself.
