3 FRDM-KW41Z overview and description
3.1 Introduction
The FRDM-KW41Z development board is an evaluation environment supporting Freescale MKW41Z
SoC transceiver. The MKW41Z SoC integrates a radio transceiver operating in the 2.
SoC transceiver. The MKW41Z SoC integrates a radio transceiver operating in the 2.
402 GHz to 2.48
GHz range (supporting a range of GFSK and O-QPSK modulations) and an ARM Cortex-M0+ MCU into a
single package. NXP supports the MKW41Z SOC 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-KW41Z
development board consists of the MKW41Z 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.

3.2 Board features
3.2.1 FRDM-KW41Z board
The FRDM-KW41Z development board is based on NXP Freedom development platform. It is the most
diverse reference design containing the MKW41Z 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. Figure 1 shows the FRDM-KW41Z development board. A similar board (not
shown) uses the MKW41Z device.
