2.1 Introduction
The 1322x USB Dongle/Zniffer is an IEEE 802.15.4 compliant wireless node based on the Freescale
MC1322x device. The heart of the 1322x USB module is Freescale’s MC1322x 99-pin LGA
Platform-in-Package (PiP) solution that can be used for wireless applications ranging from simple
proprietary point-to-point connectivity to complete ZigBee mesh networking. The MC1322x is designed
to provide a highly integrated, total solution, with premier processing capabilities and very low power
consumption.
The 1322x USB Dongle/Zniffer provides a platform to evaluate the MC1322x device, develop software
and applications, and demonstrate IEEE 802.15.4 and ZigBee networking capabilities. The dongle
connects the core device to a personal computer (PC) through a USB port <> UART port interface device.
The small form factor illustrates an extremely small footprint, 4-layer printed circuit board (PCB) layout
with a chip antenna. The MC1322x node typically interfaces to the PC through a virtual COM port (VCM).
As initially provided from Freescale, the dongle is loaded with a software application that implements a

• Reset switch to the wireless node; does not reset the USB interface device.
Refer to Figure 3-4 for location of switches and LEDs.
3.8 FLASH Memory Recovery Jumpers and Erase
The MC1322x has an onboard serial FLASH that stores the memory image that gets loaded into RAM at
boot. If it becomes necessary to change or update the image in FLASH, there are two possible means of
doing so:
• JTAG Debug Port - if the JTAG connector is mounted and the ARM debug tools are in use, the
FLASH image can be changed.
• Load new FLASH image via USB port:
— The Freescale BeeKit IDE download provides a software tool called Test Tool. This application
runs on a PC and can be used with a client running on the MC1322x to test the platform.
— Test Tool also has the capability to load a new image into the FLASH through the USB port.
However, the FLASH must first be cleared.
The 1322x USB Dongle/Zniffer has two jumper sites designated as J3 and J4 (see Figure 3-8) located on
the non-component (back) side of the PCB (see Figure 3-5). Use these jumper sites to erase the FLASH.
1. Short Jumper J3 Pin 1 to Pin 2.
2. Short Jumper J4 Pin 1 to Pin 2.
NOTE
For development purposes SMD headers can be soldered to the header sites
to make this action easily done with shorting bars.
3. Power on the USB board by plugging it into a USB port.
4. Push the reset button on the USB board.

5. Disconnect the USB board from USB port.
6. Remove the jumpers from both J3 and J4.
7. The board is now ready for boot operation. After the FLASH is erased, plug the module into the
USB connection again. The board is now ready to be loaded with a new image using the Freescale
Test Tool application.
NOTE
Refer to the Freescale Test Tool User’s Guide as supplied with Test Tool in
the BeeKit Wireless Connectivity Toolkit download.

3.9 Optional Debug/Development Interface (ARM JTAG Interface)
The module optionally supports the standard JTAG debug port. A 20-pin footprint is provided for a
standard JTAG debug interface connector. This debug port only requires a simple interface cable to
connect to a PC and use standard ARM software development tools.
The MC1322x supports connection to a subset of the defined ARM JTAG connector. The JTAG interface
is a standard 2.54mm/0.1inch spacing, 20-pin debug interface (J1). The footprint for the 20-pin connector
is located at the rear side of the module. A Pin 1 marking is given for correct plug-in of the development
cable.
Table 3-2 shows the device pins that are connected to the associated JTAG header pin outs if the JTAG
connector is used.
NOTE
The required header is a 20-position, 0.100” straight SMD connector.
