2.1 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
(a)
using the PSU output barrel connector
(+12 V) or directly from 2x36 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:

The jumper S1 can be used as switch to turn on and off the board. A linear regulator is used to generate +5 V
DC
needed for the microcontroller. D4 (green
LED) is connected to voltage regulator output for revealing 5 V presence.
Figure 3. +5 V supply section
2.1.2 Supply from USB port
The board can be fed using the +5 V from the USB cable. To enable this function both jumpers J19 and J20 have to be closed and the PSU plug can be removed, together with S1 and S2 jumpers.

2.2 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)
2.3 Reset section
In order to generate a clean reset signal for the microcontroller, STM6315RDW13F is used. SW1 button triggers such device generating a reset signal.
D8 is powered on as soon as reset pulse is generated. The reset signal can be propagated to the on board linear voltage regulator via
RESET_ASD line closing the jumper J14 (see Figure 3: +5 V supply section).

The microcontroller in the discovery board can be programmed and debugged using two methods
(b)
:
Staport wndard JT AG 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; in this case, the JTAG connector has to be connected to the target board adding a passive male-female 2x7 pin adaptor.

2.4.2 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.
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
).
Figure 8. USB connector with integrated debugger from PLS
2.4.3 Board config ured 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..:

2.5 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 .

2.6 User I/O pins
Some microcontroller GPIOs are dedicated for user purpose. Here below details about to each group.
2.6.1 User LEDs
The LEDs D7 and D8 are available for user purpose; the jumpers J9, J10 connect the 2 LEDs to the microcontroller I/O PC3 and PC2 respectively. The HW connection is reported in Figure 10: User D7 and D8 LEDs.
Figure 10. User D7 and D8 LEDs
2.6.2 Push button
A push button is connected to GPIO PA11. The pin is connected to High level by a 10 k pull-up resistor and it is set to Low (GND) when the button is pushed; a low pass filter has been added to reduce the noise and clean spurious signals.

2.6.4 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 0V ÷ VDD_HV.

Appendix A General handling precautions
The following precautions are recommended when using the SPC560B-DIS, discovery board:
Do not modify or manipulate the board when the external PSU supply is powered and connected to the board.
Do not open and modify the PSU. Use AC plug adaptor if the main socket is not compatible with the PSU plug.
Do not supply the board with a DC source higher than 12 V.
Any equipment or tool used for any manipulation of the semiconductor devices or
board modification should be shielded and connected to ground.
The connectors and cables should be plugged and removed when the board is not supplied.
It is recommended to use antistatic tools.
