After a few years of speculations and developments about i.MX7 and i.MX8 processors, Freescale announced Freescale i.MX7 family this summer. The new processors are based on one or two Cortex A7 cores coupled with a Cortex-M4 MCU for real-time tasks, and are a low power alternative to Freescale i.MX6 processors. But so far I had only seen a few announcements such Toradex i.MX7 SoM or Freescale 96Boards, without any product actually shipping, and Compulab claims to the first to market with a Freescale i.MX7 system-on-module, namely their CL-SOM-iMX7 SoM which will ship in quantities in early January 2016.
