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 FEDL610Q794-02 Issue Date: Jan. 29, 2015 ML610Q794G Sensor Control Hub 8-bit Microcontroller General Description The ML610Q794G is a high-performance 8-bit low power microcontroller optimized for sensor hub applications 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 48pin TQFP package. The ML610Q794G is an ideal sensor hub microcontroller for personal healthcare equipments, wearable devices, and sensor nodes that all require power efficient control and data collection from multiple sensors.
