STMicroelectronics Intelligent Sensor Processing Unit Integrates DSP into MEMS Sensors

STMicroelectronics, a global semiconductor company that is also a top manufacturer of Micro-Electro-Mechanical Systems (MEMS), announced the launch of its new Intelligent Sensor Processing Unit (ISPU) that combines a Digital Signal Processor (DSP) suited to run AI algorithms and MEMS sensor on the same silicon. By combining signal processing and AI algorithms onto MEMS sensors, ST enables standalone devices that are able to sense, process, and take action, while substantially saving space and power.

With the goal of elevating the user experience for a wide range of consumer devices, Cirrus Logic is leveraging its low-power, low-latency mixed-signal processing technology to develop an advanced product portfolio of haptic and sensing integrated circuits (ICs) that enable increased functionality and sleek buttonless designs for smartphones, PCs, wearables, gaming, virtual reality and automotive applications. Cirrus Logic’s haptic products and sophisticated haptic feedback technology enable sleeker, more robust end products with fewer mechanical controls for new responsive and immersive user experiences.

Asahi Kasei Microdevices Corporation (AKM) made two new product announcements focusing on 4-channel applications. The AK5704EN 4-channel 32-bit A/D audio converter was developed for high-quality low-power multi-microphone recording applications. Its built-in microphone amplifier and power supply make it an ideal solution for conference systems, microphone array systems or smart speakers. The also new AK7739VQ/AK7737VQ audio and voice processors are multicore units, designed for car audio, car navigation systems, and wireless speakers applications.
