UM1672 User manual SPC560B-DIS discovery board Introduction This document describes the hardware architecture of the board, how to configure the jumpers and to enable specific functions. November 2013 DocID025237 Rev 1 1/22 www.st.com...
HVAC, Comfort Modules, Security Access and they are suitable for ASIL B/SIL requirements. SPC560B-DIS discovery board is supported by a specific application project inside SPC5Studio (a visual integrated software development environment to easily develop software for SPC56 MCU's), that embeds micro start-up routines, I/O mapping and a simple test codes SPC5Studio is available for download www.st.com/spc5studio.
SPC560B-DIS discovery board with SPC560B54L5 UM1672 Debug interface The microcontroller can be debugged using both • JTAG standard 14 pins interface, for using external debugger tools • USB mini-B, through the PLS debugger integrated on board Microcontroller I/Os All microcontroller IOs are available on the two 2 x 36 headers with exception of JTAG, TCK, TMS, TDI, TDO, XTAL, EXTAL and VDD_LV pins.
UM1672 Hardware overview Hardware overview Figure 2. HW overview Power supply The discovery board allows wide supply configurations, such as: 12 V (external PSU) or 5 V (USB supply). 2.1.1 12 V DC power supply 12 V voltage can be used to supply the board using the PSU output barrel connector (+12 V) or directly from 2x36 headers.

UM1672 Hardware overview Crystal oscillator The SPC560B-DIS board could be populated either with 8 or 16 MHz crystal to clock the SPC560B54L5. Default configuration is with 16 MHz crystal. Figure 5. Crystal (PCB) Reset section In order to generate a clean reset signal for the microcontroller, STM6315RDW13F is used.
Hardware overview UM1672 Programming and debug The microcontroller in the discovery board can be programmed and debugged using two methods • Staport wndard JTAG connector (male 2x7 100mil - 90°) • USB with integrated debugger. A further configuration in addition to the previous configurations allows configuring the board as a standalone PLS adapter;...
USB with integrated debugger from PLS (default configuration) The integrated debugger, based on the device FTDI2232H and UDE PLS software, allows the user to build, run and debug the software applications. The SPC560B-DIS discovery kit includes a full-featured, perpetual code-limited (128 Kbytes) PLS software license; the debugger serial number is reported on a label applied on the bottom side of the board.
