Integrated 2.4GHz, IEEE 802.15.4-compliant
transceiver:
? Robust RX filtering allows co-existence with
IEEE 802.11g and Bluetooth devices
? - 99dBm RX sensitivity (1% PER, 20byte packet)
? + 3dBm nominal output power
? Increased radio performance mode (boost
mode) gives - 100dBm sensitivity and + 5dBm
transmit power
? Integrated VCO and loop filter
Integrated IEEE 802.15.4 PHY and lower MAC with
DMA
Integrated hardware support for Packet Trace
Interface for the Ember development environment
Provides integrated RC oscillator for low power
operation
Supports optional 32.768kHz crystal oscillator for
higher accuracy needs
16-bit XAP2b microprocessor
Integrated memory:
? 128kB of Flash
? 5kB of SRAM
