ST's specific MCU for digital power control of cloud

The new Digital Power microcontroller STM32F334 from STMicroelectronics is suggested for designing digital power control systems powering cloud computing systems. By using digital control of computer power supplies data-center efficiency can be increased by 60% by adjusting continuously as power demand fluctuates, according to the Uptime Institute. ST said its new microcontroller simplifies the data-center industry’s transition to energy-efficient digital power supplies, such as multi-phase interleaved or resonant soft-switching (LLC), by providing all the major power-control functions in a single chip. The 217ps high-resolution timer embedded in the STM32F334 guarantees superior precision allowing better power-supply efficiency while the asynchronous ultra-fast reaction time guarantees safe operation, says ST. “Integrating features already proved in STM32 F3 devices used for digital motor drives and solar-inverters, the new STM32F334 Digital Power line adds innovations such as the high-resolution timer, making these the industry’s most advanced microcontrollers for digital power applications,” said Michel Buffa, General Manager, Microcontroller Division, STMicroelectronics. “With built-in high-speed peripherals featuring versatile interconnects, multiple timer outputs, powerful CPU and communication peripherals, these devices greatly simplify digital control of com...
