A20-OLINUXINO-MICRO now available also in Industrial temperature grade -45+85C


We are selling for some time already A20-OLinuXino-MICRO Rev.J where few things were improved:

  1. We changed the LAN PHY from Realtek to Microchip as latter is more reliable supplier for both commercial and industrial temperature components, we searched desperately Realtek PHY in industrial temperature grade but without success.
  2. We extended the input working voltage from 6-16VDC to 8-24VDC
  3. We changed the NAND Flash to eMMC (but old NAND style flash is still possible to assembly)

The Ethernet PHY change requires new patches on the Uboot and Linux images which are already uploaded.

    In the A20 datasheet, the part is only rated for operation from -20 to 70 degrees C. How are you able to get it to work from -45 to 85? I’m interested in developing a product using the A20 or similar, but an absolute requirement is that it can operate at -30, and preferably down to -40. The A20 makes the most sense except for the poor temperature rating. I saw elsewhere some comments that the T2 is the same chip but can be ordered with a higher temperature rating, and that some of the R series as well. But information from Allwinner seems to be non-existent regarding these matters, and before spending a lot of time developing a project, I need to be assured that industrial grade CPUs will be available.
