1 About this document

This user’s guide describes the hardware for the Freescale
USB-KW019032 development platform.
The USB-KW019032 board is the core evaluation and
application development platform for the MKW01Z128
device, and can be used as a standalone evaluation solution
or used to develop software and applications.

The MKW01Z128 transceiver is a highly-integrated,
cost-effective, system-in-package (SiP), sub-GHz wireless
node solution with an FSK, GFSK, MSK, or OOK
modulation-capable transceiver, and a low-power ARM®
Cortex®-M0+ CPU. The highly integrated RF transceiver
operates over a wide frequency range including 315 MHz,
433 MHz, 470 MHz, 868 MHz, 915 MHz, 928 MHz, and
955 MHz in the license-free Industrial, Scientific, and
Medical (ISM) frequency bands.

Safety information

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 changes shown in this manual) violate the rules 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 sec tion.
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
