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 power supply
12 V voltage can be used to supply the board(a)using the PSU output barrel connector
(+12 V) or directly from 2 x 36 headers.
The PSU connector shall be center positive with 2.1 mm inner diameters.
The diode D4 protects the boards against the battery reverse connection.
The jumpers S1 and S2 allow choosing the desired 12 V supply. Table 1 depicts the jumper
configuration:

Programming and debug
The microcontroller in the discovery board can be programmed and debugged using two
methods(b):
•
Standard JTAG connector (male 2 x 7 100 mil - 90°)
•
USB port with integrated debugger.
A further configuration in addition to the previous configurations allows configuring the board
as a standalone PLS adapter; in this case, the JTAG connector has to be connected to the
target board adding a passive male-female 2 x 7 pin adaptor.

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 SPC560D-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 bottom side of the board.
To download the debugger software and to activate license go to the PLS website.
The integrated debugger is accessible via ST's free integrated development environment,
SPC5Studio (www.st.com/spc5studio).

2.4.3
Board configured as PLS adapter
The discovery board can be configured to work as standalone PLS adapter, configuring
jumpers as described below (see Table 3: Programming and debug - Jumper setting). The
board serial number is reported in a label on the board.
Using such configuration the JTAG connector is connected to the JTAG application board; a
passive adapter can be added to converter from male to female the 2 x 7 JTAG port
soldered on the board. The 3.3 V or 5 V compatibility is achieved by using level shifters
array.
2.4.4
HW configuration
In order to enable one of the previous described functionalities, the board has to be properly
set. The USB integrated debugger is the default configuration.
Table 3 shows how to configure the jumpers also to enable the board as PLS adapter.

1. J20 connect the GND of the board to the GND of the USB input. This jumper should be removed when the
USB section must be electrically insulated
2. S1 is used as power switch; if S1 is left open, the 12 V form external source does not supply the board
3. If S2 is present and the 12 V supply comes from the daughters boards, J16 must be left unconnected (no
external PSU must be powered and connected).

USB and Graphic User Interface (GUI)
One of the two FTDI2232 channels has been configured for implementing a serial
communication between PC USB and microcontroller UART, both for serial booting or for
controlling the microcontroller using a dedicated GUI.
The USB section (serial communication) is electrical insulated with respect to all the circuitry
adding opto-couplers in series to the path of TX and SX signals (see Figure 9: GUI: TX and
RX signals with optocoupler).

Hardware overview
Boot configuration
It is possible to reprogram microcontroller internal flash programming using Boot Assist
Mode (BAM) via SCI. The pins PA8 and PA9, (see Figure 12: User I/O pins PC4, PA8 and
PA9) have to be configured to enable the BAM functionality as following:
•
FABM (PA9) has to be connected to VDD_HV to enable serial boot (J13 jumper
closed).
•
ABS (PA8) has to be physically grounded to flash via SCI (J12 jumper closed).
If the BAM function is not used, these pins can be configured as normal I/O according to the
functions reported in the datasheet (see Section Appendix B: Reference documents).
2.6.5
ADC input
A trimmer connected to the microcontroller PB8 input allows the user to check ADC. The
analog input voltage range is 0 V ÷ +VDD_HV.
