electronica, Munich 2018 and Hoofddorp, Netherlands: Murata has today announced the availability of a new narrowband Internet-of-Things (NB-IoT) cellular modem module which, at just 12.6 mm x 10.6 mm x 1.8 mm, is the smallest in the world. The small size and low power consumption (~3uA in power saving mode) makes the 1SS module ideal for miniaturized battery-operated IoT devices such as wearables or tracking devices, where battery lifetimes up to ten years are achievable.
Based upon the Mediatek MT2625 chipset and housed in a shielded package, the module includes an ARM® Cortex®-M4 microcontroller (MCU) running at 156 MHz. The module is able to run AT commands due to the onboard SRAM and 4 MB of Flash memory. The module includes multiple GPIO lines, a UICC interface for SIM cards and SPI and UART interfaces providing designers with flexibility. Further flexibility is delivered through an open MCU option that allows designers to run their own applications.
Ensuring the widest possible compatibility with varied use cases, the 1SS modem module supports a large range of protocols including TCP/IP, DTLS, Ping, LwM2M, CoAP, HTTP/HTTPS for the web, MQTT for the IoT, iperf, SNTP and SIM toolkit. Compliant with GSMA GCF / PTCRB certifications, the 1SS module simplifies the design process as well as reducing cost and time to market.
The module operates from -40°C to +85°C making it ideal for harsh environments and requires only a single 3.3 V supply rail. The modules can run on a range of 1.8 – 3.3 V, optimized for dry-cell devices.
Murata will be showing the device in Hall C4 – Stand 141 at electronica in Munich. Samples are available now and the modem will enter mass production during Q1 2019.
