This application note describes the implementation of an audio signal detector with the SLG47512. The design can detect human speech or music and can ignore single tone noise or flat random noise. The audio signal detector can be used in safety services or to save energy in audio decks.

This application note describes a solution to control AC-Power with a cycle skip logic along with system monitoring features using GreenPAK™. At hardware level, a push button controls 4 8-bit patterns programmed on-chip, and at software level, a 16-bit pattern is modified through I2C. The solution can be expanded to include more patterns along with pattern length at both hardware and software level.

This application note describes a GreenPAK based solution to control AC-Power with a phase cut logic along with system monitoring features. A push button controls 2 phase delays programmed onchip at hardware level, and an I2C compatible MCU modifies the phase delays at software level via I2C. The solution can be expanded to include more programmed delays for hardware control and additional system monitoring features.

This solution demonstrates a compact, low-cost, single-board computer. The dual-core MPU and matching PMIC provide enough horsepower to run graphical human machine interface (HMI) and artificial intelligence (AI) edge applications concurrently. The system features many wired interfaces and supports Wi-Fi, Bluetooth^® Low Energy, and near field communication (NFC) wireless connectivity.

System Benefits:

• Powerful dual-core MPU with integrated DRP-AI engine supports running graphical HMI and edge-based AI/ML from a single device
• Power management IC (PMIC) and RZ MPU are matched, reducing overall design complexity and system cost
• Dual gigabit Ethernet, Wi-Fi, Bluetooth Low Energy and NFC provide versatile options for cloud connectivity and offload

Applications:

• Machine vision, cameras, edge AI inferencing
• IoT gateways and hubs
• Human Machine Interface (HMI)
