1 Introduction
This chapter introduces the NXP JN516x USB Dongle (DR1198), which provides
a hardware development platform for wireless microcontroller applications with a
USB interface.
1.1 Overview
The JN516x USB Dongle features a JN516x wireless microcontroller and allows
communication with this JN516x device from a USB connection. The JN516x
device can act as a node of a wireless network. Thus, the dongle provides an
easy way of interfacing a host machine (such as a PC) to a wireless network
based on the IEEE802.15.4, JenNet-IP, ZigBee PRO (ZigBee Light Link or Smart
Energy) or ZigBee-RF4CE networking protocol. An FTDI device provides the
USB connection between the host machine and the JN516x device, which in turn
provides the radio interface to the wireless network.
Note: The JN516x device used in this USB dongle design can
be an NXP JN5168-001, JN5164-001 or JN5161-001 wireless
microcontroller. Full details of the JN516x range of devices
can be found in the JN516x Data Sheet (JN-DS-JN516x).
Typical uses of the dongle include:
•A complete and stable hardware environment for the development of
IEEE802.15.4, JenNet-IP, ZigBee PRO (ZigBee Light Link or Smart
Energy) and ZigBee-RF4CE networking applications, facilitating an
accelerated time-to-market for wireless network products
•The basis of a packet sniffer for IEEE 802.15.4-based wireless
communications
•A means of integrating the host machine into a wireless network, typically
as the network Co-ordinator
The small-footprint PCB of the dongle provides all the necessary components for
a wireless microcontroller with access to a USB connection. All RF layout and
decoupling issues are handled by the design of this dongle. Therefore, this
design is ready for application development without the necessity of hardware
development.
The JN5168 USB Dongle, shown below, is supplied in the JN516x-EK001
Evaluation Kit.

2.3 Hardware Components
The following hardware components on the board are described in the sub-
sections below.
•JN516x wireless microcontroller – see Section 2.3.1
•FTDI FT232RL driver device – see Section 2.3.2
•LEDs – see Section 2.3.3
•32-kHz crystal oscillator – see Section 2.3.4
2.3.1 JN516x Device
The JN516x wireless microcontroller used in the dongle design can be an NXP
JN5168-001, JN5164-001 or JN5161-001 device. The JN516x range of wireless
microcontrollers is detailed in the JN516x Data Sheet (JN-DS-JN516x).
The JN516x circuit on the board is based around the standard JN516x Module
Reference Design (JN-RD-6038). However, it is built on a 2-layer board, as the
DIOs do not need to be externally available.
The JN516x device uses an integrated antenna on the PCB of the dongle. Note
that in the Reference Design JN-RD-6039, the PADS source file does not include
the PCB antenna - it must be obtained from the Gerber files.
2.3.2 FT232RL Device
The FT232RL device is connected to the USB connector and acts as an
interface between the PC and the JN516x device. The FT232RL will enumerate
on the PC as a virtual COM port connected directly to UART0 on the JN516x
device.
The IO controls C2 and C3 in the FT232RL device need to be set to ’I/O Mode’
to allow the RESET and PGM signals to operate correctly. To do this, follow the
instructions below.
1. Download the application FT_Prog from the FTDI website
(www.ftdichip.com).
2. Insert the JN516x USB Dongle into a USB port of your computer and wait
for the device to enumerate.
3. Start FT_Prog and click Scan and Parse ( the magnifying glass button).
4. Update the IO controls C2 and C3 to I/O MODE – see screenshot below.

2.3.3 LEDs
There are two surface-mounted LEDs that can be controlled by the JN516x
wireless microcontroller (see Figure 2 for locations):
•LED D1 (green)
•LED D2 (orange)
Both LEDs are connected to DIO16 and DIO17. These DIOs can be used to
control the LEDs as indicated in the table below.

DIO16
Low D1: Off D1: Off
D2: Off D2: On
High D1: On D1: Off
D2: Off D2: Off

2.3.4 32-kHz Crystal Oscillator
The JN516x device has an internal 32-kHz RC oscillator. In order to provide
more accurate system timings, an external 32-kHz crystal can be used with the
device. This is provided on the JN516x USB Dongle and can be enabled from
the JN516x application using the JN516x Integrated Peripherals API - refer to the
JN516x Integrated Peripherals API User Guide (JN-UG-3087).

3 Flash Programming
When the JN516x USB Dongle is powered up, it attempts to run an application
from the internal Flash memory of the JN516x device. This may be a self-
contained application that sends and receives wireless data, and which does not
need to communicate with the host. Alternatively, it may communicate via the
USB with an application running on the host, such as a Windows program, and
also communicate with a wireless device or network.
In order to program an application binary into Flash memory, the JN51xx Flash
Programmer can be used, which is described in the JN51xx Flash Programmer
User Guide (JN-UG-3007). This programming utility will place the JN516x into its
programming mode. It will then download the program to the Flash memory and
reset the JN516x device, causing the application to be executed.
