Introduction
This guide describes the hardware for the FRDM-KW40Z
Freescale Freedom development board. The FRDM-KW40Z
Freedom development board is a small, low-power,
and cost-effective evaluation and development board for
application prototyping and demonstration of the MKW40Z
SoC family of devices. These evaluation boards offer
easy-to-use mass-storage-device mode flash programmer,
a virtual serial port, and standard programming and
run-control capabilities.
The MKW40Z SoC is an ultra-low-power, highly integrated
single-chip device that enables Bluetooth Low Energy
(BLE) and/or IEEE
®
Std. 802.15.4/RF connectivity for
portable, ultra-low-power embedded systems.
The MKW40Z SoC family integrates a radio transceiver
operating in the 2.36 GHz to 2.48 GHz range (supporting a
range of FSK/GFSK and O-QPSK modulations), ARM
®
Cortex
®
-M0+ CPU, 160 KB flash memory and 20 KB
SRAM, BLE Link Layer hardware, 802.15.4 packet
processor hardware, and peripherals optimized to meet the
requirements of the target applications.

Safety information
FCC guidelines
This equipment is to be used by developers for evaluation purposes only, and must not be incorporated into
any other device or system. This device must not be sold to the general public. Integrators are 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 guide) may violate the rules of the
Federal Communications Commission and Industry Canada and make the 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
The device must comply with part 15 of the FCC rules. Operation is subject to these 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
The device must comply with FCC radiation exposure limits set forth for an uncontrolled environment.
Install the antenna(s) used by the device to provide a separation distance of at least 8 inches (20 cm) from
all persons.
2.1.4
Antenna restrictions
An intentional radiator must be designed to ensure that no antenna (other than that furnished by the
responsible party) is used with the device. Using a permanently attached antenna or 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
using 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. This requirement does not apply to intentional radiators
that must be professionally installed (such as perimeter protection systems and field disturbance sensors)
or to other intentional radiators which must be measured at the installation site (in accordance with Section
15.31(d)). The installer is responsible for ensuring that a proper antenna is employed (to not exceed the
limits in this Part).

2.2
Regulatory approval for Canada (IC RSS 210)
This equipment complies with Industry Canada license-exempt RSS standard(s). Operation is subject to
these two conditions:
1. This board must not cause interference.
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 the damage from electrostatic discharge (ESD) is much less common on these devices when
compared to the early CMOS circuits, use standard handling precautions 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 must conform to 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 must conform to the JESD78 IC Latch-Up Test.
When operating or handling the development boards or components, Freescale strongly recommends
using at least grounding wrist straps, plus any (or all) of these 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.

FRDM-KW40Z overview and description
Introduction
The FRDM-KW40Z development board is an evaluation environment supporting Freescale MKW40Z
SoC transceiver.
The MKW40Z SoC integrates a radio transceiver operating in the 2.36 GHz to 2.48 GHz range (supporting
a range of FSK/GFSK and O-QPSK modulations) and an ARM Cortex-M0+ MCU into a single package.
Freescale supports the MKW40Z S
O
C with tools and software that include hardware evaluation and
development boards, software development IDE, applications, drivers, custom PHY usable with IEEE Std.
802.15.4 compatible MAC, BLE Link Layer, and enables the usage of the Bluetooth Low Energy protocol
in the MBAN frequency range for proprietary applications.
The FRDM-KW40Z development board consists of the MKW40Z device with 32 MHz reference
oscillator crystal, RF circuitry (including antenna), 2-Mbit external serial flash, and supporting circuitry
in the popular Freedom form. The board is a standalone PCB and supports application development with
Freescale IEEE Std. 802.15.4 protocol stacks.

Board features
FRDM-KW40Z board
The FRDM-KW40Z development board is based on Freescale Freedom development platform. It is the
most diverse reference design containing the MKW40Z device and all necessary I/O connections for use
as a standalone board, or connected to an application. You can also connect it to the Freedom development
platform.
