ZL70250 PRODUCT PROFILE

Ultra Low Power RF Transceiver

Product Status: Production

Overview

The ZL70250 ultra low-power radio frequency (RF) transceiver provides a wireless link in applications where powerconsumption is of primary importance. The tranceiver's ultra low-power requirements allows the use of a miniature button cell battery or energy-harvesting methods, enabling devices with extremely small form factor.

The availability of the tranceiver as bumped die combined with the extremely low number of external components also contributes in minimizing the application footprint.

The ultra low-power IC operates in unlicensed frequency bands between 795 - 965 MHz and offers data rates up to 186 kbps to support voice communication. Duty cycling can be employed for applications that require lower average payload to further reduce power consumption.

The device includes the RF transceiver as well as a Media Access Controller (MAC) that performs most link support functions including Received Signal Strength Indication (RSSI), Clear Channel Assessment (CCA), sniff, preamble & sync, packetization and whitening. The device uses standard interfaces, enabling easy integration with a standard microcontroller or Digital Signal Processor (DSP).

Zarlink's ZLE70250 Application Development Kit (ADK) enables rapid evaluation, prototyping and development of RF telemetry systems using the ZL70250 ultra low-power (ULP) Industrial Scientific and Medical (ISM) transceiver technology.
