STMicroelectronics SPC584B-DIS

Overview

SPC584B-DIS from STMicroelectronics is a low-cost Discovery board for evaluating and developing applications with the SPC584B70E1 32-bit Power Architecture MCU-featuring a 120 MHz e200z4 core, 2 MB Code Flash, eTQFP64 package, ASIL-B compliance, and integrated CAN-FD, DSPI, and LINFlexD peripherals.

For engineers reviewing the SPC584B-DIS datasheet, SPC584B-DIS pinout, SPC584B-DIS application, or SPC584B-DIS equivalent, this board supports rapid prototyping of automotive-grade embedded control systems, USB-based debugging via PLS Integrated Programmer/Debugger, Arduino UNO-R3 shield compatibility, and full access to all MCU pins through dual-row headers and JTAG interface.

Technical Context

The board hosts the SPC584B70E1 microcontroller with dedicated power management (VDD_HV_IO_MAIN/VDD_HV_ADV configurable via JP3/JP4), a 40 MHz crystal oscillator (X2) with jumper-selectable external clock input, and a hardware reset circuit using STM6315RB-2.63V supervisor IC.

It integrates a PLS-based on-board debugger supporting SWD/USB programming and virtual COM port (USART over USB), while providing dual power paths: +5 V from USB or 7–12 V external supply regulated to +3.3 V and +5 V via U2/U3 linear regulators, with SELV-compliant isolation.

FAQ

Does the SPC584B-DIS include an on-board debugger?

Yes-the board integrates a PLS-based programmer/debugger accessible via USB, enabling firmware flashing, real-time debugging, and virtual COM port communication without external tools. The debugger serial number is printed on the board's bottom-side label, and software is supported by SPC5Studio IDE.

Can the SPC584B-DIS be powered from an external source?

Yes-it supports four power configurations: USB +5 V (default), external 7–12 V via VIN pins, external +5 V via E5V pins, or independent +3.3 V/+5 V supplies via E3V3/E5V jumpers. Voltage selection is controlled by SB14–SB27 solder jumpers per Table 1 in UM2461.

What Arduino-compatible interfaces does the board provide?

The board features CN5/CN6/CN8/CN9 connectors fully compliant with Arduino UNO-R3 pinout, exposing analog inputs (A0–A5), digital PWM pins (D0–D15), I²C (SCL/SDA), UART (RX/TX), and power rails (IOREF, 3.3 V, 5 V, GND, VIN). All signals map directly to SPC584B70E1 GPIO or peripheral functions.

Is JTAG debugging supported?

Yes-a standard 2×7-pin JTAG header (CN1) is provided for third-party debuggers, with TDI, TDO, TCK, TMS, PORST, and JCOMP signals routed. Note: the male connector is not assembled; users must solder a 2×7 header to use external JTAG tools.
