Dialog works with Murata to simplify low power Bluetooth design
It is a small device which the supplier claims draws just 3.8mA for wireless transmission and reception.
The interesting aspect of the DA14580 Bluetooth transceiver is its availability in pre-certified modules designed through a partnership with Murata.
With a deep sleep current of under 600nA, the transceiver can be powered by a 225mAh coin-cell battery sending 20 bytes of data per second with a battery life of over four years.
It will also work off 0.9V enabling the use of just one alkaline or NiMH cell AA battery.
The DA14580 is available in a wafer-level chip-scale package (WL-CSP) measuring 2.5×2.5×0.5mm.
