Design Advantages
QFN-Style Solder-Down
Compact 27mm square QFN package with thermal pad. Single-sided assembly leaves the underside of the carrier board free, and visual solder joint inspection remains possible after soldering.
QS Family Pin-Compatible
Standard QS pinout across the QS Family enables a scalable platform strategy. Design one baseboard and migrate between processors as application requirements evolve.
Cost-Effective Entry
Single-core Cortex-A7 with 256 MB RAM delivers the lowest QSMP price point for cost-sensitive industrial HMI and control applications.
10-Year Longevity
STMicroelectronics 10-year longevity program plus industrial-grade components ensure your product design remains in production for years.
