ZL70550
Ultra-Low-Power Sub-GHz RF Transceiver
Microsemi’s ZL70550 RF transceiver is the lowest‑power
sub‑GHz radio for high‑ or low‑duty‑cycle, wireless‑sensor
applications. The device is optimized for very low power
consumption in both active and sleep states, making it the
leading choice for sensor networks that are powered by a coin‑
cell battery or an energy harvesting power source.
The ZL70550 device is also highly integrated and requires,
in addition to the antenna, only a crystal, two decoupling
capacitors, and a resistor. Available as a 2‑mm‑by‑3‑mm CSP,
the device enables applications with a very small footprint.
The ZL70550 device operates in unlicensed frequency bands
between 779 MHz and 965 MHz and offers a maximum raw
data rate of 200 kbit/s at 2.4 mA (typical) with a respectable
sensitivity of −95 dBm.
The device includes the Z‑Star protocol, which is a powerful
and highly optimized MAC that performs complete packet
transmissions with acknowledgments and automatic
retransmissions on failed receptions. This built‑in protocol
eliminates the need for processor intervention in packet
processing, allowing the processor to go to a power‑save state
or to perform other critical application processing. Additionally,
the MAC supports other user modes of operation with selectable
options like CRC, FEC, and auto length.
