1322x Network Node Module Overview and Description
1322x Network Node Reference Manual, Rev. 1.1
2-2 Freescale Semiconductor
2.2 Features
The 1322x Network Node provides the following features:
• Full IEEE 802.15.4 compliant wireless node; ZigBee capable with Freescale’s BeeStack software
stack
• Based on Freescale’s third-generation MC1322x ZigBee platform which incorporates a complete,
low power, 2.4 GHz radio frequency transceiver, 32-bit ARM7 core based MCU, hardware
acceleration for both the IEEE 802.15.4 MAC and AES security, and a full set of MCU peripherals
into a 99-pin LGA Platform-in-Package (PiP)
• MC1322x provides a highly integrated, low cost RF node
— On-board balun and antenna switch in package
— Typical -95 dBm sensitivity
— Typical 0 dBm output power, with max approximately +2 dBm
— SMA connector with external antenna
• USB interface is bus-powered and full-speed compatible to the USB 2.0 and 1.1 specifications
• 128x64 pixel chip-on-glass monochrome, graphic LCD with LED backlight
• Audio subsystem
— 2.5mm audio jack for microphone and mono earpiece
— Input amplifier and anti-aliasing filter for an electret microphone
— Output path to second order analog filter from either 10-bit serial DAC or PWM as output
signal sources
— I2C controlled 32-position linear nonvolatile volume control for audio circuit
— Audio output amplifier for both earpiece or on-board dynamic speaker (switched by headset
jack)
• Two debug / development interfaces
— 20-pin connector for standard JTAG debug interface
— 38-pin MICTOR connector for extended NEXUS real-time debug interface
• Power management circuit with on-board regulation for multiple power sources
— Can be powered from USB interface, DC power jack or two AA batteries
— On/Off power switch
— Power-on green LED
• User interface switches and LEDs
— 4-directional TACT switch with center push for application purposes
— 4 pushbuttons for application purposes
— 4 processor controlled red LEDs for application purposes
— Reset switch
• 26-pin user header for selected General Purpose Input Output signals and data interfaces
• System clock options
— Default 24 MHz crystal reference oscillator (13 to 26 MHz crystal optional)
