The Infineon PSOC Edge E81, E83, and E84 MCU series is a dual-core Cortex-M55/M33 microcontroller with an optional Arm Ethos U55 microNPU and 2.5D GPU that enables IoT, consumer, and IoT applications to benefit from machine learning acceleration. , designed for industrial applications.
This is a follow-up to Infineon's completely useless announcement about the PSoC Edge Cortex-M55/M33 microcontroller in December 2023, with the new announcement not showing any actual parts that might be used in the design. Masu. The PSOC Edge E81 series is an entry-level ML microcontroller, the PSOC Edge E83 series adds more advanced machine learning with his Ethos-U55 microNPU, and the PSOC Edge E84 series further adds his 2.5D GPU for HMI applications. add.

The PSOC Edge family is supported by ModusToolbox software, which includes a board support package (BSP), peripheral driver library (PDL), middleware such as CAPSENSE, and integration with the Imagimob Studio AI solution and its off-the-shelf ML models. Lady model. Information about the PSOC Edge development kit is limited, but we do know that it features a system-on-module, Arduino expansion header, sensor suite, BLE connectivity for provisioning, and Wi-Fi for smartphone and cloud connectivity. It was also demonstrated at Embedded World 2024 and can be seen in the video embedded below.
The PSOC Edge 81, 83, and 84 series are targeted at other smart home devices including appliances, speakers, wearables, robotics, and connected IoT products. PSOC Edge E81 provides entry-level ML computing for features such as anomaly detection, predictive maintenance, acoustic event detection, keyword spotting, wake word detection, voice prompts, and gesture/motion/presence detection. The Edge E83 series enables voice/audio wake word detection with an always-on acoustic activity detection mechanism for battery-powered devices, while the PSOC Edge E84 can power similar applications with graphical user interfaces .
The PSOC Edge family is only available to early access customers at this time, so there may be a lack of information and documentation. More information, including product overview, can be found on the product page and press release.
