Texas Instruments Sitara AM654 Cortex-A53/R5 SoC was launched in 2018 as the first 64-bit processor from the company and specifically targetting Gigabit industrial Ethernet networks with support for Time-Sensitive Networking (TSN).
Since the processor launch, we’ve seen a couple of Sitara AM65xx modules such as PHYTEC phyCORE-AM65x SoM and Mistral AM65x Industrial SOM. There’s now another option with TQ Embedded TQMa65xx embedded module featuring a choice of 5 AM65xx dual-/quad-core processor, up to 4GB RAM, up to 64GB eMMC flash, and various I/Os via a 560-pin connector that includes six Gigabit TSN Ethernet interfaces.
TQ Embedded TQMa65xx embedded module specifications:

The company provides Linux OS support with software by Kunbus by default, but QNX and Android operating systems are also available on request. As a side note, Kunbus is the German company making RevolutionPi RevPi DIN-rail industrial computer based on Raspberry Pi board or Compute Module 3 SoM.
Eventually, there should be a Wiki for the module, but it’s empty at the time of writing. The module is said to be particularly suitable for applications in the area of real-time communication (TSN) and fieldbuses with protocols such as Ethercat, Profinet, or Profibus.
It will take a little while before the module is ready for mass-production however, as the first prototypes are only scheduled for August 2020. More details may be found in the announcement and product page.
