PSOC™ Edge E81 Next Generation of ML Enabled MCUs

The PSOC™ Edge E81 series of Arm® Cortex®-M microcontrollers feature high-performance, low-power, secured MCUs with hardware-assisted machine learning (ML) acceleration for next generation applications. The PSOC Edge devices are based on high-performance Cortex-M55, including Helium DSP support as well as a low-power Cortex-M33 paired with Infineon’s ultra-low power NNLite hardware accelerator intended to accelerate neural networks in Machine Learning and AI applications. In addition, the PSOC™ Edge E81 features always-on acoustic activity detection capability that enables HMI operation with low active and standby power consumption supporting longer battery life for battery powered products.

The PSOC™ Edge E81 includes support for voice and audio communications with keyword spotting and wake word detection included, as well as timing peripherals built for a variety of consumer and industrial applications including HMI, smart home, wearables, robotics, and other smart connected IoT products.  In addition, PSOC™ Edge is supported by a rich set of enablement with the industry-recognized ModusToolbox software including integration with the Imagimob Studio AI solution and its off-the shelf ML models.
