STM32 Performance Series
The STM32 Performance series features performance ARM Cortex cores such as M4, M7, and M33 with high clock frequencies. This family, even if energy efficient in computing, is intended not to work in energy-constrained environments. Performance series offers bigger RAM and Flash memories, advanced features oriented toward creating rich user interfaces, such as Chrome-ART Graphic Accelerator, and HDMI support. This series also provides developers advanced instruction sets such as DSP and FPU. STM32 Performance Series chips are bigger, more expensive, and more power-consuming. This last factor, however, can be controlled with advanced power management features.
Applications that benefit from the STM32 Performance series include industrial automation, high-performance IoT devices, motor control, multimedia, audio processing, and more. Performance Series MCUs are often used in applications where there is a need for power and feature-rich peripherals such as displays, cameras, video processing, etc.
A short review of the MCUs and their features is listed in table 1.
Note each row in the table represents a family of devices, and a particular configuration depends on the exact MCU model. Thus, developers, when looking for specific features, should refer to the manufacturer's specifications and list of currently available devices [1].
