2 Safety information
2.1 FCC guidelines
This equipment is to be used by developers for evaluation purposes only, and it must not be incorporated
into any other device or system. This device is not to be sold to the general public. Integrators will be
responsible for reevaluating the end product (including the transmitter), and obtaining a separate FCC
authorization.
The FCC approval of this device only covers the original configuration of this device (as supplied).
Any modifications to this product (including changesshown inthis manual)violate therules of the Federal
Communications Commission and Industry Canada, and make operation of the product unlawful.
2.1.1 Labeling
The FCC labels are 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 must not cause harmful interference
• This device must accept any interference received, including interference that can 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
eight inches (20 cm) from people.
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 unique
coupling to the intentional radiator) is considered sufficient to comply with the provisions of this section.
The manufacturer can 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 802.15.4 standard. Further on, 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 a 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 must not cause interference
2. This board must accept any interference, including interference that can 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 the
early CMOS circuits, normal handling precautions must 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).
The latch-up 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 MKW01Z128 transceiver is a single-chip integrated circuit ideally suited for today's
high-performance ISM-band RF applications. It is intended to be used as a high-performance, low-cost
FSK and OOK RF transceiver for robust, frequency-agile, half-duplex bi-directional RF links.
The MKW01Z128deviceis intended for applications overa widefrequency range, includingthe 868 MHz
European ISM band, and the 902—928 MHz North American ISM bands. Output power ranges from -18
dBm to +13 dBm (on the RF_IO port).
The USB-KW019032 uses a flexible RF path topology that makes it suitable for working in different
frequency bands by replacing minimum number of components, while providing good RF performance.
The tables in Section 4.3.1, “Bill of materials” show different BOMs according to different frequency
bands of operation.
Figure 6 shows a typical topology of the RF circuitry. The footprint enables installing the U.FL connector
J49 for measurement purposes. When using J49, C58 must be installed and C50 removed.
