FRDM-KW36 Freedom Development Board User's Guide
Rev. 4 - 01/2020

1 Introduction

This guide describes the hardware for the FRDM-KW36 Freedom
development board. The FRDM-KW36 Freedom development board is highly
configurable, low-power, and cost-effective evaluation board for application
prototyping and demonstration of the KW36A/35A and KW36Z/35Z family of
devices. This evaluation board offers easy-to-use mass-storage-device mode
flash programmer, a virtual serial port, and standard programming and run-
control capabilities.
The KW36 is an ultra-low-power, highly integrated single-chip device that enables Bluetooth
(at 250, 500 and 1000 kbps) for portable, low-power embedded systems.
The KW36 integrates a radio transceiver operating in the 2.36 GHz to 2.48 GHz range supporting a range of GFSK, an Arm
Cortex-M0+ CPU, up to 512 KB Flash and up to 64 KB SRAM, Bluetooth LE Link Layer hardware and peripherals optimized to
meet the requirements of the target applications.

2 Overview and description

The FRDM-KW36 development board is an evaluation environment supporting KW35Z/36Z/35A/36A (KW36) Wireless
Microcontrollers (MCU). The KW36 integrates a radio transceiver operating in the 2.4 GHz band (supporting a range of GFSK
and Bluetooth LE) and an Arm Cortex-M0+ MCU into a single package. NXP supports the KW36 with tools and software that
include hardware evaluation and development boards, software development IDE, applications, drivers, and a custom PHY with
a Bluetooth LE Link Layer. The FRDM-KW36 development board consists of the KW36A device with a 32 MHz reference crystal
oscillator, RF circuitry (including antenna), 4-Mbit external serial flash, CAN and LIN transceivers and supporting circuitry in the
popular Freedom board form-factor. The board is a standalone PCB and supports application development with NXP's Bluetooth
LE and Generic FSK libraries.
