3.2 Design Overview
The heart of the 1322x-LPB 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 main attributes of the 1322x-LPB module are:
• Small footprint with a 2-layer PCB and F-antenna
• Support for very low power operation
• Support for Lithium coin cell operation
• Support for optional buck converter
• Support for 32.768 KHz crystal oscillator
• Support for non-standard reference oscillator crystal (13-26 MHz and requires use of PLL filter)
