SMIC and Sanechips Release First Commercial NB-IoT Chip Designed and Manufactured in China

Semiconductor Manufacturing International Corporation (SMIC) from China, and Sanechips Technology, previously known as ZTE Microelectronics Technology, have released the first commercial NB-IoT chip designed and manufactured by Chinese firms independently. The RoseFinch7100, is based on SMIC's 55 nm ULP+RF+eFlash (Ultra Low Power+ Radio Frequency +embedded Flash) technology, and can be extensively used in wireless meters, shared bikes, smart appliances, smart city, smart agriculture, and in other IoT fields.

The 55 nm ULP+RF+eFlash technology platform from SMIC is ideal for ultra-low-power IoT applications. The process and performance improvements are based on the stable 55 nm logic and mix-signal technologies. The nominal operating voltage can be lowered 30%, and the device will reduce 45% of dynamic power consumption, and 70% of static power consumption, as well as lowering the SRAM leakage. Furthermore, the platform is compatible with RF and eFlash technologies and has complete IP solutions. Compared with other technology nodes, SMIC 55 nm ULP+RF+eFlash technology is a reliable platform for low power IoT SoC design; it can meet the strict requirements of NB-IoT for low stand-by power consumption and small package size.

Based on SMIC's complete 55 nm ultra low power technology platform and Sanechips' powerful design capabilities, the NB-IoT SoC RoseFinch7100 is specially designed for extensive low power IoT applications. Its sleep power is 2 uA which accounts for 16% of its total power consumption while sending and receiving message once per day. In addition, it uses single chip design with minimum peripherals and supports R14 full band with integrated cloud-chip security performance as well as open application architecture.

SMIC's strong manufacturing capabilities effectively guarantee the commercialization of Sanechips' new generation of NB-IoT chips on time. According to the test results, the chip's function and performance all met the expected requirements and achieved leading industry benchmarks in several core indicators of IoT related applications, including sleep power consumption, cut-off voltage, and peripheral interface quantity, with the obvious advantages of low cost and low power consumption. The world-leading chip is now catching up to the launch schedules of China's big three telecomm operators.
