GLOBALFOUNDRIES and VeriSilicon have collaborated to deliver the first single-chip IoT solution for next-generation Low Power Wide Area (LPWA) networks. Leveraging GF’s 22FDX FD-SOI technology, the companies plan to develop intellectual property that could enable a complete cellular modem module on a single chip, including integrated baseband, power management, RF radio and front-end module combining both Narrowband IoT (NB-IoT) and LTE-M capabilities. The new approach is expected to deliver significant improvements in power, area, and cost compared to current offerings.
With the proliferation of connected devices for smart cities, homes, and industrial applications, network providers are developing new communications protocols that better meet the needs of emerging IoT standards. LPWA technology takes advantage of the existing LTE spectrum and mobile infrastructure, but focuses on delivering ultra-low power, extended range, and much lower data rates for devices that transmit small amounts of infrequent data, such as connected water and gas meters.
The two leading LPWA connectivity standards are LTE-M, which is expected to get traction in the U.S. market, and NB-IoT, which is gaining ground in Europe and Asia. For example, the Chinese government has targeted NB-IoT for nationwide deployment over the coming year. The combination of these two technologies is expected to push cellular M2M module shipments to nearly half a billion by 2021, according to ABI Research.
GF and VeriSilicon are developing a suite of IP to enable customers to create single chip cost- and power-optimized solutions for worldwide deployment, based on a dual-mode carrier-grade baseband modem with integrated RF front-end module. The design will be fabricated using GF’s 22FDX process, which leverages a 22 nm FD-SOI technology platform to provide cost-effective scaling and power reduction for IoT applications. 22FDX is the only technology that allows efficient single-chip integration of RF, transceiver, baseband, processor, and power management components. This integration is expected to deliver more than an 80 percent improvement in both power and die size compared to today’s 40 nm technologies.
GF and VeriSilicon expect to tape out a test chip based on the integrated solution, with silicon validation in Q4 2017. The companies plan to pursue carrier certification in mid-2018.
