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 FEDL62Q1500-06 Issue Date: Jul 15, 2020 ML62Q1500/1800 Group 16-bit micro controller GENERAL DESCRIPTION ML62Q1500/1800 Group is a high performance CMOS 16-bit microcontroller equipped with an 16-bit CPU nX-U16/100 and integrated with program memory(Flash memory), data memory(RAM), data Flash and rich peripheral functions such as the multiplier/divider, CRC generator, DMA controller, Clock generator, Simplified RTC, Timer, General Purpose Ports, UART, 2 Synchronous serial port, I C bus interface unit (Master, Slave), Buzzer, Voltage Level Supervisor(VLS), Successive approximation type A/D converter, D/A converter , Analog comparator, Safety function(IEC60730/60335 Class B) and so on. The CPU nX-U16/100 is capable of efficient instruction execution in 1-instruction 1-clock mode by pipeline architecture parallel processing. The built-in on-chip debug function enables debugging and programming the software. Also, ISP(In-System Programming) function supports the Flash programming in production line. The ML62Q1500/1800 Group has seven packages (48pin - 100pin) and ten kinds of memory sizes(32Kbyte - 512Kbyte).
