SoC Qualcomm Snapdragon Wear 1200 supports LTE Cat-M1/NB1
Yesterday, Qualcomm introduced a new single chip system for wearable devices: Snapdragon Wear 1200. Recall that SoC Snapdragon Wear 1100 was presented over a year ago.
Let’s start with the parameters. The new SoC is based on the same Cortex-A7, as SW1100, but the frequency increased up to 1.3 GHz. Given the fact that neither in the parameter list, nor in the press release does not specify the process by which designed a new solution, we can assume that it has remained the same: 28 nm.
The main difference novelties from its predecessor is in the modem. It supports LTE Cat-M1/NB1 with the speed of admission to 300/20 kbps and transfer — 375/60 kbit/s. For comparison, the Snapdragon Wear the speed reaches 10 and 5 Mbps, respectively.
That is, the new solution is not designed to replace last year. It is aimed at devices with even lower power consumption for which high-speed data transfer through cellular networks is simply not needed. Qualcomm tells about the activity trackers, devices GPS trackers for Pets, and so on. You also need to acknowledge the support 15 global frequency ranges.
Of course, there is support for GPS, GLONASS, Beidou and Galileo. There is also support Linux and ThreadX. The dimensions of the chip are only 72 mm2.
