NXP nomenclature for their i.MX 8M processors can be a little confusing. First discovered in 2016, the original i.MX 8M processor family comes with one to four Arm Cortex-A53 cores, a real-time Cortex M4 core, targets multimedia application with FullHD or 4K decoding/encoding support and is manufactured using a 28nm process.
NXP then announced i.MX 8M Mini processor family in February 2018 with a 14-nm FinFET processor allowing a higher maximum CPU frequency of 2.0 GHz, less video output interfaces (no HDMI, nor DisplayPort), and optional Full HD video encoder and decoder, .e.g no 4K. Finally, earlier this year, the company unveiled NXP i.MX 8M Nano further power-optimized with the same 14nm manufacturing process, but a lower frequency of 1.5 GHz, and a Cortex-M7 core replacing the Cortex-M4 core found in previous i.MX 8M processors. This allows i.MX 8M Nano SoC to have a 2W TDP, and achieve sub-watt power consumption in IoT edge projects.
We’ve already written about i.MX 8M Mini based hardware, but so far no i.MX 8M Nano system-on-module or single board computer had come to our attention, and iWave Systems iW-RainboW-G34M-SM system-on-module will come with either Mini or Nano version of the processor.
