1322x-LPB Module Overview and Description
2.1 Introduction
The 1322x-LPB is an IEEE 802.15.4 compliant wireless node based on the Freescale MC1322x device.
The heart of the MC1322x 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-LPB provides a platform to evaluate the MC1322x device, develop software and applications,
demonstrate IEEE 802.15.4 and ZigBee networking capabilities, and implement low power operation. The
small form factor illustrates a small footprint, 2-layer printed circuit board (PCB) layout with integrated
printed-wire F-antenna. The LPB provides a GPIO connector to interface with application devices, a
separate second unbuffered UART connector, and a full JTAG debug port connector.

The 1322x-LPB is specifically intended as a prototype development platform for low power applications,
use of the buck converter, 2-layer PCB design, use of the 32.768 crystal oscillator, and non-standard crystal
reference oscillators (requiring PLL operation).
