LAPIS Semiconductor starts mass-production of ultra-compact microcontrollers that take integrated control of various sensors installed on smart phones with low power consumption

LAPIS Semiconductor ML610Q792

LAPIS Semiconductor provides a total solution with its microcontrollers combined with a rich variety of sensors manufactured by the ROHM Group

PackageFor the smart phone market, LAPIS Semiconductor, a ROHM Group company, has developed “ML610Q792,” one of the world’s smallest class of low power microcontrollers. This microcontroller can take integrated control of various sensors with low power consumption. Recently, the ratio of smart phones to mobile phones has been increasing steadily. On the other hand, load on the battery of a smart phone has also been increasing because of installation of more sensors for provision of new applications and services. Paying attention to this fact, LAPIS Semiconductor has separated sensors required to be driven all the time from the host processor so that the sensors can be controlled by a low power microcontroller. This has led to reduction of load on the host processor and has also enabled the life of the battery to be longer. With its low power consumption used effectively, “ML610Q792” can be applied to applications, such as sensor network modules, in combination with radio communication systems.

LAPIS Semiconductor: ML610Q792

“ML610Q792” has its original high-performance 8bitRISC CPU Core (U8) and a 16-bit coprocessor for multiplication and division operations. It also has two interfaces: one for connecting sensors and the other for connecting to the main chipset. The package size of “ML610Q792” is 3.1 mm × 3.0 mm. LAPIS Semiconductor has achieved this compactness by adopting its packaging technology WL-CSP*1. In addition, “ML610Q792” provides a development board containing various sensors and various drivers needed for users’ embedment. It also provides Software Development Kit (SDK)*2 containing sample source codes for logging, pedometer, and calorie calculation.

One of the ROHM Group’s strategies is “Sensor-related business.” ROHM has developed a wide range of sensors so far, such as proximity sensors, ambient light sensors, hall IC, temperature sensors, touch panel sensors, CIGS image sensors, UV sensors, and pulse wave sensors. In addition, Kionix, Inc., a major vendor of accelerometer and gyroscope, has joined the ROHM Group. Due to this joining, ROHM can now provide a rich lineup of top-class sensors among device manufacturers. By combining this rich lineup of sensors with its low power microcontrollers, LAPIS Semiconductor will provide higher-value added and more customer-convenient solutions.
