QFN-style SoM delivers low-power 64-bit solution for intelligent edge processing
EP&T MagazineElectronics Karo Processor QFN-style semiconductors SoM system on module
KARO ELECTRONICS QS93 miniature QFN-style system-on-module (SoM) provides a low-power 64-bit solution for intelligent edge processing. Based on NXP’s dual-core i.MX935 with ARM Cortex-A55 processors, plus RAM, Flash memory and power management, device measures 27x27mm square with a height of 2.7mm and delivers improved EMC and thermal performance. Manufactured by Aachen-based Ka-Ro Electronics, SoMs are available as solder-down modules on tape and reel packaging, which suits mid- and high-volume production runs. A socket-ready SODIMM version, TX93, is also available for low run and development purposes. QS93 module’s i.MX935 processor provides a dual 1.5GHz ARM Cortex-A55 core as well as a separate ARM Cortex-M33 running at 250MHz. There is 1GB of LPDDR4 RAM and 4GB eMMC Flash available and a wide range of interfaces including dual USB and dual Ethernet. The i.MX935 also includes an Arm Ethos U-65 microNPU which affords energy-efficient implementation of machine learning (ML) tasks.
