Sony’s 28nm FD-SOI GPS rolling out in the Xiaomi Amazfit smartwatch is “…a big win for Sony” and “…an even bigger win for FD-SOI’s promoters,” said Junko Yoshida of EETimes (see Sony-Inside Huami Watch: Is It Time for FD-SOI?). Then she adds:“Huami’s watch decidedly demonstrates the technology’s claim to ultra-low power consumption.”
Xiaomi is a subsidiary of Huami, which lays claim to being the second largest manufacturer of wearables in the world. So it really is a big win. What’s more, the Amazfit, says Xiaomi, is “…the world’s first smartwatch with a 28 nm GPS sensor”.
Sony has been releasing evolving details of the chip at various conferences over the last few years (including SOI Consortium forums). To get their ISSCC paper, 26.5 A 0.7V 1.5-to-2.3mW GNSS receiver with 2.5-to-3.8dB NF in 28nm FD-SOI (February 2016) from IEEE Xplore – click here.
