Startup delivers lowest power NB-IoT and eMTC baseband chip: Page 2 of 2

December 06, 2017 // By Jean-Pierre Joosting
Vancouver-based startup Riot Micro has made its market debut with the Riot Micro RM1000 chip, which claims to be the industry’s lowest power baseband modem chip for the cellular Internet of Things (IoT) – reducing power consumption by up to 50 percent.

Riot’s RM1000 is a hardware-centric baseband controller, tightly coupled to an optimized LTE protocol stack running on an ultra-power efficient integrated processor. The PHY layer implemented completely in hardware enables minimal eDRX cycle power consumption and extremely fast wake/sleep transition times. These power savings mean that IoT modules based on the RM1000 can run longer on lower capacity batteries, further saving on system cost.  Riot’s hardware-based architecture assures that power consumption is always minimized regardless of traffic patterns and use cases.

Alternative solutions typically require a 100MHz+ processor speed, external memory, and on-chip PLLs for a high-speed clock, increasing silicon area, power consumption, and cost. Software-based PHY solutions also have longer startup and shutdown due to firmware load and processing, which ultimately costs battery life.

The RM1000 is available now, supplied to OEMs and module manufacturers developing custom products, in an 8- x 8-mm 68 pad QFN package or a 3.5- x 3.2-mm WLCSP package. Riot Micro offers a full-range of customer support services, including reference designs, for evaluation and module design.
