VAR-SOM-AM43
TI AM437x
Supporting the 1GHz Sitara™ AM437x ARM® Cortex™-A9 processor from Texas Instruments (TI) with quad 200MHz real-time programmable unit (PRU) and a rich 2D/3D graphics accelerator. The quad PRUs are ideal for offloading real-time processing from the main Cortex CPU, managing deterministic tasks and supporting dedicated industrial protocols. The PRUs alongside the rich industrial connectivity of the VAR-SOM-AM43 System on Module / Computer on Module makes it an optimized solution for products targeting automation, robotics, controllers, HMI and other industrial segments.
With dual GbE, USB, touch controller, audio, certified Wi-Fi 802.11 a/b/g/n with optional MIMO and Bluetooth/BLE, the VAR-SOM-AM43 is also highly integrated with support for a wide range of operating systems.

Newsroom
Adding TPM 2.0 to an embedded product usually starts with a hardware question: where does the security chip go? On Variscite’s i.MX-based modules, there is now another answer. Variscite and SecEdge are bringing SecEdge’s TPM 2.0 firmware, anchored in the processor’s own security hardware, to Variscite’s i.MX System on Module portfolio.
Blog
Pierluigi Passaro, Variscite’s R&D expert, introduces the VAR-SOM-MX8M-MINI and the VAR-SOM-MX8M-NANO – two cost-optimized modules designed for applications that require power-efficient processing, graphics capabilities, and real-time performance. Both SoMs are available with flexible memory, storage, and wireless configurations, allowing developers to pay only for the features they need.
