Safety and regulatory compliance information
Regulatory compliance information
Contains Transmitter Module FCC ID: VPYLB1DX and IC: 772C-LB1DX
This kit is intended to use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES
ONLY and is not considered by Infineon Semiconductor to be a finished end product fit for general consumer
use. It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the
limits of computing devices pursuant to part 15 of FCC or ICES-003 rules, which are designed to provide
reasonable protection against radio frequency interference. Operation of the equipment may cause
interference with radio communications, in which case the user at his own expense will be required to take
whatever measures may be required to correct this interference.
The kit contains Murata’s Type 1YN (LBEE5KL1YN) certified module. Due to change in the antenna
pattern/type and gain used in CY8CPROTO-062S2-43439 PSoC™ 62S2 Wi-Fi Bluetooth® prototyping kit, class II
permissive changes are required to recertify this kit. The radiated emission tests must be performed again to
obtain a new FCC ID for this host kit. Most conducted RF test results may still be reused. Customer also needs to
take their product through other FCC/ISED testing such as unintentional radiators (FCC sub part 15B) and any
other required regional product certifications including but not limited to EU directives. Refer FCC Regulatory
Certification Guide by Murata on information on pre-certified and reference certified module concepts and
information on what additional test are required for FCC certification. Customer should consult a
Telecommunication Certification Body (TCB) lab for guidance on other requirements for the device
certification.
For more details on Murata Type 1YN module refer www.murata.com/en-global/products/
connectivitymodule/wi-fi-bluetooth/overview/lineup/type1yn.
PSoC™ 62S2 Wi-Fi Bluetooth® prototyping boards contain electrostatic
discharge (ESD)- sensitive devices. Electrostatic charges readily accumulate
on the human body and any equipment, which can cause a discharge without
detection. Permanent damage may occur on devices subjected to high-
energy discharges. Proper ESD precautions are recommended to avoid
performance degradation or loss of functionality. Store unused PSoC™ 62S2
Wi-Fi Bluetooth® prototyping boards in the protective shipping package.

Kit operation
The PSoC™ 62S2 Wi-Fi Bluetooth® prototyping board consists of multiple sections, a KitProg3 section, PSoC™6
MCU section and other peripheral sections. An on-board programmer, KitProg3 is used to program and debug
the target PSoC™6 MCU. Refer to 2.2 KitProg3 and 3.2 Hardware functionaldescription for more details on
these sections.
Figure 5 Board –top view
The board has the following peripherals:
1. KitProg3 USB connector (J8): The USB cable provided along with the PSoC™ 62S2 Wi-Fi Bluetooth®
prototyping board connects between this USB connector and the PC to use the KitProg3 onboard
programmer and debugger and to provide power to the board.
2. KitProg3 programming mode selection button (SW3): This button can be used to switch between various
modes of operation of KitProg3 (CMSIS-DAP/Bulk or CMSIS-DAP/HID mode). This button can also be used to
provide input to PSoC™5LP in custom application mode. For more details, see the KitProg3 user guide.By
default, the programming mode is set to CMSIS-DAP/ Bulk which allows faster programming than CMSIS-
DAP/HID.

5. KitProg3 I/O headers (J6, J7): These headers bring out the USB-UART and USB-I2C interface pins of the
KitProg3. If the KitProg3 Section is broken away, it is also necessary to connect VTARG and GND as those are
used for voltage level translation. For more details on the KitProg3, see the KitProg3 user guide.
6. KitProg3 5-pin programming header (J4): This header brings out the SWD interface pins of the KitProg3.
This is used to program and debug the PSoC™6 MCU. If KitProg3 section is broken away, it can be used to
program any device over the 5-pin interface. Please note that VTARG is an input to KitProg3, and hence the
target must be powered externally in that case. The on-board regulators on the PSoC™6 MCU section
provide VTARG. For more details on the KitProg3, see the KitProg3 user guide.
7. PSoC™6 MCU I/O headers (J1, J2): These headers provide connectivity to PSoC™6 MCU GPIOs. Most of
these I/Os are also connected to on-board peripherals.
8. PSoC™6 MCU user LED (LED4): The user LED can operate at the entire operating voltage range of PSoC™6
MCU. The LED is active LOW, so the pins must be driven to ground to turn ON the LED.

PSoC™6 MCU using an external programmer such as MiniProg4.Please note that this header is not loaded
by default.
19.PSoC™6 MCU user button (SW2): This button can be used to provide an input to the PSoC™ 6 MCU. Note
that by default the button connects the PSoC™ 6 MCU pin to ground when pressed, so you need to configure
the PSoC™ 6 MCU pin as a digital input with resistive pull-up for detecting the button press. This button also
provides a wake-up source from low-power modes of the device. In addition, this button can be used to
activate the PMIC control from PSoC™ 6 MCU.
20.System power selection jumper (J3): This jumper is used to select the PSoC™ 6 MCU’s supply voltage
(P6.VDD) between 1.8 V and 3.3 V.
