STMicroelectronics 

SN260

ZigBee® 802.15.4 network processor

Features

■ 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.

■ Integrated IEEE 802.15.4 PHY and MAC

■ Dedicated peripherals and integrated memory

■ EmberZNet™ ZigBee®-compliant stack

running on the dedicated network processor

■ Controlled by the Host using the EmberZNet™

Serial Protocol (EZSP)

– Standard serial interface (allows for

connection to a variety of Host micro

controllers)

■ Non-intrusive debug interface (SIF)

■ Integrated hardware and software support for

InSight Development Environment

■ Provides integrated RC oscillator for low power

operation

■ Three sleep modes:

– Processor idle (automatic)

– Deep sleep—1.0µA

– Power down—1.0µA

■ Watchdog timer and power-on-reset circuitry

■ Integrated AES encryption accelerator

■ Integrated 1.8V voltage regulator

■ Compatible with Ember EM250
