Safety information
2 Safety information
2.1 FCC guidelines
This equipment is for use by developers for evaluation purposes only and must not be incorporated into
any other device or system. This device may not be sold to the general public. Integrators will be
responsible for reevaluating the end product (including the transmitter) and obtaining a separate FCC
authorization.
FCC approval of this device only covers the original configuration of this device as supplied. Any
modifications to this product, including changes shown in this manual, may violate the rules of the Federal
Communications Commission and Industry Canada and make operation of the product unlawful.
2.1.1 Labeling
FCC labels are physically located on the back of the board.
2.1.2 Operating conditions
This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:
• This device may not cause harmful interference.
• This device must accept any interference received, including interference that may cause undesired
operation.
2.1.3 Exposure limits
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
The antenna(s) used for this equipment must be installed to provide a separation distance of at least 8
inches (20 cm) from all persons.
2.1.4 Antenna restrictions
An intentional radiator is designed to ensure that no antenna other than that furnished by the responsible
party is used with the device. The use of a permanently attached antenna or of an antenna that uses a unique
coupling to the intentional radiator is considered sufficient to comply with the provisions of this Section.
The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of
a standard antenna jack or electrical connector is prohibited. This requirement does not apply to carrier
current devices or to devices operated under the provisions of Sections 15.211, 15.213, 15.217, 15.219, or
15.221 of the IEEE Std. 802.15.4. This requirement does not apply to intentional radiators that must be
professionally installed, such as perimeter protection systems and some field disturbance sensors, or to
other intentional radiators which, in accordance with Section 15.31(d), must be measured at the installation
site. However, the installer is responsible for ensuring that the proper antenna is employed so that the limits
in this Part are not exceeded.

Safety information
2.2 Regulatory approval for Canada (IC RSS 210)
This equipment complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to
the following two conditions:
1. This board may not cause interference, and
2. This board must accept any interference, including interference that may cause undesired operation
of the device.
2.2.1 26 PART 5 – Appendix
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de
licence. L'exploitation est autorisée aux deux conditions suivantes:
1. l'appareil ne doit pas produire de brouillage, et
2. l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage
est susceptible d'en compromettre le fonctionnement.
2.3 Electrostatic discharge considerations
Although damage from electrostatic discharge (ESD) is much less common on these devices than on early
CMOS circuits, normal handling precautions should be used to avoid exposure to static discharge.
Qualification tests are performed to ensure that these devices can withstand exposure to reasonable levels
of static without suffering any permanent damage.
All ESD testing is in conformity with the JESD22 Stress Test Qualification for Commercial Grade
Integrated Circuits. During the device qualification ESD stresses were performed for the human body
model (HBM), the machine model (MM) and the charge device model (CDM).
All latch-up test testing is in conformity with the JESD78 IC Latch-Up Test.
When operating or handling the development boards or components, Freescale strongly recommends
using at least the grounding wrist straps plus any or all of the following ESD dissipation methods:
• Flexible fabric, solid fixed size, or disposable ESD wrist straps
• Static control workstations, static control monitors, and table or floor static control systems
• Static control packaging and transportation materials and environmental systems

4.2.1 RF performance and considerations
The USB-KW40Z board’s integrated transceiver includes a 1 mW nominal output power PA with internal
voltage controlled oscillator (VCO), integrated transmit/receive switch, on-board power supply regulation,
and full spread-spectrum encoding and decoding. Key specifications for the MKW40Z160 SoC are:
• Nominal output power is set to 0 dBm
• Programmable output power from -20 dBm to +5 dBm at the MMCX, no harmonic trap
• Typical sensitivity is -102 dBm (@1% PER for 25 °C) at the MMCX (802.15.4)
• Typical sensitivity is -91 dBm (@1% PER for 25 °C) at the MMCX (BLE)
• Frequency range is 2360 to 2480 MHz
• Differential bidirectional RF I/O port with integrated transmit/receive switch
• Meander printed metal antenna for a small footprint, low cost design
• Uses a minimum number of RF marching components and external 50:100 balun
An external 50 (bal): 100 (unbal) balun connects a single-ended 50 ohm port to the differential RF port of
the MKW40Z160 SoC’s transceiver. The layout has provision for out-of-band signal suppression
(components L3 and C20) if required. Figure 6 shows the typical topology for the RF circuitry. The RF
connector J4 has been included in the design for measurement purposes and is used as a DNP.

4.2.2 Clocks
The USB-KW40Z provides two clock sources to the MKW40Z160:
• 32 MHz Reference Oscillator - Figure 7 shows the external 32 MHz external crystal Y1. This
mounted crystal must meet the specifications outlined in the AN3251 application note. The IEEE
Std. 802.15.4 requires that the frequency be accurate to less than ±40 ppm.
— Capacitors C4 and C5 provide the bulk of the crystal load capacitance. At 25 °C, it is desired
to have the frequency accurate to ±10 ppm or less to allow for temperature variation.
• Optional 32.768 kHz Crystal Oscillator: Provision is also made for a secondary 32.768 kHz crystal
Y2 (see Figure 8). This oscillator can be used for a low power accurate time base.
— The module comes provided with this Y2 crystal and its load capacitors C6 and C7.
— Load capacitors C6 and C7 provide the entire crystal load capacitance; there is no onboard trim
capacitance.

4.2.3 Power management
There is one way to power on the USB-KW40Z board, a J5 type-A connector to supply 5 V(V_USB)
directly to the secondary MCU, that includes an internal regulator, 3.3 V output to enable theMKW40Z160
device. The USB-KW40Z power management circuit is shown in Figure 9.
Figure 9. USB-KW40Z power management circuit
Additionally, a green LED marked as D1 is available as a power indicator. For current measurements, users
can isolate the MKW40Z160 device, through SH13 cut-trace, this will disable the VCC path (including
LED).
