10 cool processors for the IoT

摘要

If you are designing nodes for the frontier of the IoT, the good news is that there are plenty of silicon outfitters. The challenge is figuring out what you need and mapping that to the growing landscape of suppliers.The following list of 10 processors includes - in no particular order - some of the most interesting recent options that point to major trends in IoT silicon. You may not find an exact fit for your deployment, but hopefully, the list will guide you along some useful pathways.Microsoft worked with MediaTek to make this processor the reference chip for Azure Sphere, its all-in-one node-to-cloud IoT offering announced in April. It's part of a wave of integrated solutions emerging from cloud providers including Alibaba and Amazon.Microsoft distinguished its approach by defining a so-called Pluton security block, implemented in the MT3260 on an Arm Cortex-M4F core that handles security operations. The part also includes a 500-MHz Cortex- A7 apps processor with 4-MB SRAM, a Wi-Fi subsystem, and support for 16-MB external flash.
