Murata shrinks NBIoT module and stretches battery life

What is believed to be the world’s smallest narrow-band Internet of Things (NBIoT) cellular wireless module is now available from Murata.

The LBAD0ZZ1RX measures 15.6  x 14.0  x 2.2 mm, is made on a PCB with a metal casing, and is designed for use in compact, battery powered IoT/IIoT applications.

The module integrates a HiSilicon Hi2115 single-die wireless system on chip device that provides the radio transceiver, baseband and application processor functions. In addition, the module hosts a DC/DC converter, a power management IC, wireless front end matching components such as baluns and low pass filters and an RF switch.

The HiSilicon Hi2115 includes an Arm Cortex M0 processor core running at 40 MHz and is equipped with 64 kBytes of SRAM and 256 kBytes of Flash that controls module communications using the industrial standard AT command set.

The module features a comprehensive set of peripheral interface functions including UART, I²C and SPI along with GPIO and an ADC.

Designed to operate in the low and middle bands, the module conforms to the NB-IoT 3GPP release 13 narrow-band standard.

The low power characteristics of the LBAD0ZZ1RX suits it to a variety of small battery powered IoT applications and it is capable of sustaining a 10 year battery life.

Mass production is scheduled for Q1 2019.

Murata manufactures electronic components, modules, and devices. The complete range includes ceramic capacitors, resistors/thermistors, inductors/chokes, timing devices, buzzers, sensors and EMI suppression filters.

While the company is known as a global ceramic capacitor manufacturer, it is also a leader in Bluetooth and wifi Modules, board-mount DC-DC converters and manufactures standard and custom AC-DC power supplies.

Established in 1944, Murata is headquartered in Japan and has European offices in Finland, France, Germany, Hungary, Italy, the Netherlands, Spain, Switzerland and the UK.
