Ultra-Low Power, Ultra-Compact Sensor Hub Microcontroller for Smartphones

LAPIS Semiconductor (formerly OKI Semiconductor), a ROHM Group company, announces the development of the ML610Q792 Sensor Hub Microcontroller—the industry’s smallest microcontroller designed for integrated, low-power control of multiple sensors in smartphones.

The ML610Q792 makes it possible to deploy new cloud-based features and services in smartphones that would otherwise be prohibitive due to increased power consumption. It logs user environment data and detects user activity without disturbing the host processor. And its remarkably low power consumption not only prolongs battery life, but enables support for wireless communication in compact products like pedometers and smartphone accessories.

The microcontroller incorporates an original high-performance 8-bit RISC CPU Core (U8) and 16-bit coprocessor for arithmetic calculations. Dual interfaces allow for both sensor connection and connecting to the main chipset, while the ultra-compact WL-CSP form factor (3.1mm x 3.0mm) supports high-density designs. In addition, a development board containing multiple sensors and drivers is provided along with a Software Development Kit (SDK) that includes sample source code and libraries for data logging, calorie calculation, pedometer function, and device drivers for interfacing with the host processor.

One of ROHM Group’s future growth strategies is to offer total sensor solutions that provide greater added-value through product synergy combining ROHM sensors (proximity, ambient light, Hall ICs, temperature) and Kionix accelerometers and gyroscopes with Lapis Semiconductor low-power microcontrollers.
