STM32 F0 MCUs from ST support crystal-less USB design

STMicroelectronics has extended its STM32 F0 microcontrollers based on the ARM Cortex-M0 core with new models that support crystal-less USB design, accurate sensing and smart power management for next-generation smart devices and connectivity products. The new STM32F0x2 line provides a combination of features not found in other ARM Cortex-M0 devices, such as support for CAN and a full-speed USB 2.0 controller with a self-calibrated clock system that simplifies design and saves external circuitry. Other USB functionality includes support for Battery-Charger Detection, which allows battery-powered devices to optimize recharging times with better flexibility, and Link-Power Management, which enables energy saving through enhanced system control. Separate power domains for analog and digital I/Os support low-voltage operation while allowing a higher voltage dynamic range for accurate sensing on analog peripherals. “This latest expansion of our highly efficient STM32 F0 series brings significant extra functionality and cost improvement ideally bridging the 8- and 16-bit world with the widely deployed STM32 F1 Cortex-M3 series,” said Michel Buffa, General Manager, Microcontroller Division, STMicroelectronics. “Communication gateways, smart-energy devices, Internet-of-Things applications and consumer electronics such as smartphones and game terminals can now leverage the unique ...
