‘Smallest’ Bluetooth Smart modules unveiled
Murata has introduced the LBCA series of ultra low power, ultra low form factor Bluetooth Smart modules.
Measuring just 5.4 x 4.4mm, the surface mount devices are said to be a quarter of the size of previous models and are aimed at the wearable electronics market, especially devices such as fitness monitoring, smart watches and remote controllers.
Conforming to the Bluetooth 4.0 low energy protocol, the modules are available both with (LBCA2HNZYZ) or without a built-in antenna (LBCA2BZZFZ).
With a 0dBm output power, the devices typically have a range of 30m. Interfaces include UART, SPI, I2C and GPIO. Peak current consumption is up to 4.5mA, dropping down to a deep sleep current of 0.6uA or less.
Average current consumption during communications is 6uA when 20bytes of data are transmitted once per second. It is anticipated that with this use case, up to four years operation is possible.
