AK8928 is a type of application-specific integrated circuit (ASIC). It is designed to provide a power efficient solution to human-machine interaction (HMI). It provides reliable interface between human interface hardware (HID) and human control applications, all within a single chip. This makes it a popular choice for embedded applications requiring reliable input, display, and control with minimal power usage.

The AK8928 is a high performance integrated circuit, capable of sensing multiple forms of HMI input such as gamepad sticks, buttons, switches, and rotary encoders. The chip also provides a variety of interfaces, such as GPIO, UART, SPI, I2C and I2S. It supports up to 8-way analog-to-digital converters (ADCs) for analog signals, and includes a dedicated interrupt mechanism.

The AK8928 is designed to be easily incorporated into an application-specific design. It is integrated with firmware for multiple operating systems, and supports software-driven application interactions for maximum agility and efficiency. In addition, the chip includes a wide variety of dedicated digital, analog, and power-saving features.

The AK8928’s operating principles can be grouped under two main categories: input sensing and output control. For input sensing, the AK8928 uses an array of 16-bit ADC conversions to detect all forms of input, which can then be used to signal the microcontroller. For output control, the AK8928 provides a variety of output interfaces, such as GPIO, SPI, UART, I2C and I2S. Additionally, the integrated voltage regulator allows the operating of multiple power supplies within the same system.
