Newsroom
We are pleased to announce the launch of the VAR-SOM-6UL – a new System on Module powered by NXP’s i.MX 6UL/ 6ULL / 6ULZ ARM Cortex-A7 processor with up to 900MHz CPU Clock. The VAR-SOM-6UL is based on Variscite’s popular DART-6UL platform while integrating additional LVDS bridge option, all packed in SO-DIMM200 form factor to fit the VAR-SOM Pin2Pin family. Adding the New module to the Pin2Pin family offers full scalability to Variscite’s customers.
The VAR-SOM-6UL is a highly integrated System on Module, optimized for power, size, and cost. The SoM design is based on the popular DART-6UL platforms and supports the same features and connectivity options, including dual Ethernet, dual USB, audio, camera in, Bluetooth/BLE, CAN Bus, Touch, PWM, ADC, as well as support for industrial temperature grades -40 to 85°C. In addition, the new platform has been enhanced with LVDS bridge via SoM and on SoM two certified WiFi configuration – single-band 802.11b/g/n or dual-band WiFi 802.11ac/a/b/g/n.
The new platform has been customized to fit the ‘VAR-SOM Pin2Pin family, providing a scalable pin-compatible option to i.MX 6 and i.MX 8 platforms. The Pin2Pin family offers Variscite’s customers a high level of scalability, extended lifetime availability, and reduced development time, cost, and risk. For example, customers can easily scale up their end-product to a higher performance SoM, such as the VAR-SOM-MX8X, to improve the graphics performance, or to scale down from other pin-compatible platforms to the VAR-SOM-6UL, to optimize the end products’ cost-performance.
