SN260
ZigBee® 802.15.4 network processor
Features
â– Integrated 2.4GHz, IEEE 802.15.4-compliant
transceiver:
– Robust RX filtering allows co-existence
with IEEE 802.11g and Bluetooth devices
– - 97.5dBm RX sensitivity (1% PER, 20byte
packet)
– + 3dBm nominal output power
– Increased radio performance mode (boost
mode) gives –98.5dBm sensitivity and
+5dBm transmit power
– Integrated VCO and loop filter
– Secondary TX-only RF port for applications
requiring external PA.
â– Integrated IEEE 802.15.4 PHY and MAC
â– Dedicated peripherals and integrated memory
■EmberZNet™ ZigBee®-compliant stack
running on the dedicated network processor
â– Controlled by the Host using the EmberZNetâ„¢
Serial Protocol (EZSP)
– Standard serial interface (allows for
connection to a variety of Host micro
controllers)
â– Non-intrusive debug interface (SIF)
â– Integrated hardware and software support for
InSight Development Environment
â– Provides integrated RC oscillator for low power
operation
â– Three sleep modes:
– Processor idle (automatic)
– Deep sleep—1.0µA
– Power down—1.0µA
â– Watchdog timer and power-on-reset circuitry
â– Integrated AES encryption accelerator
â– Integrated 1.8V voltage regulator
â– Compatible with Ember EM250
