Tizen has been commercialized in smart TV, smartphone, wearable devices (Gear S, Gear Fit), and smart home appliances. However, the low-end and low-cost IoT devices, such as home appliances without LCD and wearable bands with a small LCD, have received less attention. The goal of Tizen RT is to extend the Tizen platform device coverage to these kind of low-end devices. Tizen RT is an RTOS-based lightweight platform that it can fit into these devices, which are typically equipped with Cortex-M/R processors with MPU, less than 2 MB RAM, and less than 16 MB Flash.
Tizen RT consists of lightweight RTOS called TinyAra, IoT protocols, such as IoTivity and LWM2M, and JerryScript/IoT.js, as shown in the following figure.

The following figure illustrates the Tizen RT development, with green-colored boxes and gray-colored boxes released in 2016 and 2017, respectively. Tizen RT is first commercialized in the low-end home appliances in the first or second quarter of 2017.
