STMicro’s STM32G4 Microcontrollers Address Next-Gen Digital Power Apps

June 3, 2019 Alix Paultre

STMicroelectronics’ STM32G4 microcontrollers use hardware mathematical accelerators to boost processing of applications using Cordic and Filtering functions, among a range of features to support increased performance and energy efficiency. Targeting advanced digital power applications, the MCUs speed calculations such as trigonometry for energy-saving motor controls in appliances or air conditioners, and filtering for signal conditioning or digital power control.

Additional features include higher-resolution power conversion timers, with various built-in functions that offload the CPU and ease developers’ lives, advanced analog peripherals and converters, ultra-speed connections, and support for USB-C with Power Delivery for fast charging or powering devices up to 100W.

“Cutting-edge consumer and industrial products can now deliver more for less, leveraging the innovations we have engineered into the STM32G4 series,” said Ricardo De Sa Earp, General Manager of STMicroelectronics’ Microcontroller Division. “Building on the unprecedented concept of the STM32F3 series, which integrates rich, enhanced peripherals and interfaces with the industry-standard Arm core, our latest microcontrollers now extend the application reach and help simplify design at the same time as reducing power consumption and boosting performance.”

STM32G4 MCUs also offer features such as a scalable securable memory area for secret storage and secure live firmware upgrade, debug-access prevention after programming to reduce threat surfaces, state-of-the-art AES-256 encryption, unique device ID, and a true random-number generator. Prices start from $1.68 (10,000-unit price) for the STM32G431K6U6 with 32Kbyte Flash memory in the 32-pin QFN32 package.
