Samsung begins production of the first Exynos chip for internet-of-things

Samsung has begun mass production of its first Exynos processor for internet-of-things devices. The chip has an ARM Cortex R4 processor and Samsung makes it on its older 28nm hkmg process.

Samsung calls the chip Exynos i T200. In addition to the 32-bit Cortex R4 processor, there is a Cortex M0+ processor core. That is the most economical processor core on ARM architecture and it is intended for the lightest tasks a device wants to perform. That should extend the battery life of iot devices with this processor.

The chip supports WiFi via the 802.11b/g/n standards, which means that support for WiFi-ac and 5GHz is missing. A physically separate Security Sub-System is available for security. Samsung also mentions a Physical Unclonable Function, which allows authentication without having a key hardcoded into the processor.

There are no known products that work with the Exynos i T200. It is the first Exynos chip for iot devices. Samsung has been making socs for smartphones under the Exynos name for years. The manufacturer uses that in its Galaxy S and Note phones, and cheaper models also increasingly have the Exynos socs from its own factories.
