Dear customer st LAPIS Semiconductor Co., Ltd. LAPIS Semiconducto), on the 1 day of October, 2020, implemented the incorporation-type company split (shinsetsu-bunkatsu) in which LAPIS established a new company, LAPIS Technology Co., Ltd. (LAPIS Technology) and LAPIS Technology succeeded LAPIS Semiconductors LSI business. Therefore, all references toLAPIS Semiconductor Co., Ltd,LAPIS Semiconducto and/orLAPI in this document shall be replaced withLAPIS Technology Co., Ltd Furthermore, there are no changes to the documents relating to our products other than the company name, the company trademark, logo, etc. Thank you for your understanding. LAPIS Technology Co., Ltd. October 1, 2020 FEDL610Q793-02 Issue Date: Jan. 26, 2015 ML610Q793 8-bit Microcontroller for Sensor Control General Description The ML610Q793 is a high-performance 8-bit low power microcontroller optimized for sensor hub, that integrates LAPIS Semiconductors original high-performance 8-bit CPU core with a 16-bit multiplier/divider co-processor, 64 KByte flash memory, 4 KByte RAM, multiple interfaces for various sensors and host interfaces with 8KByte logging RAM in small footprint package. The ML610Q793 is an ideal sensor hub microcontroller for smart phone to separate various sensors off from its application processor and control them effectively for reducing total system power consumption.
