RF Modem Features
Fully compliant IEEE 802.15.4 transceiver supports 250 kbps O-QPSK data in 5.0 MHz channels
and full spread-spectrum encode and decode
Operates on one of 16 selectable channels in the 2.4 GHz ISM band
-1 dBm to 0 dBm nominal output power, programmable from -27 dBm to +3 dBm typical
Receive sensitivity of <-92 dBm (typical) at 1% PER, 20-byte packet, much better than the IEEE
802.15.4 specification of -85 dBm
Integrated transmit/receive switch
Dual PA ouput pairs which can be programmed for full differential single-port or dual-port
operation that supports an external LNA and/or PA.
Three low power modes for increased battery life
Programmable frequency clock output for use by MCU
Onboard trim capability for 16 MHz crystal reference oscillator eliminates need for external
variable capacitors and allows for automated production frequency calibration
Four internal timer comparators available to supplement MCU timer resources
Supports both packet data mode and streaming data mode
Seven GPIO to supplement MCU GPIO

Software Features
Freescale provides a wide range of software functionality to complement the MC1321x hardware. There
are three levels of application solutions:
1. Simple proprietary wireless connectivity.
2. User networks built on the IEEE 802.15.4 MAC standard.
3. ZigBee-compliant network stack.
1.5.1
Simple MAC (SMAC)
Small memory footprint (about 3 Kbytes typical)
Supports point-to-point and star network configurations
Proprietary networks
Source code and application examples provided
1.5.2
IEEE 802.15.4-Compliant MAC
Supports star, mesh and cluster tree topologies
Supports beaconed networks
Supports GTS for low latency
Multiple power saving modes (idle doze, hibernate)
