ROHM Semiconductor LAPIS ML610Q305/ML610Q306 8-Bit Microcontrollers

ROHM Semiconductor LAPIS ML610Q305//ML610Q306 8-Bit Microcontrollers are high-performance 8-bit CMOS microcontrollers that integrate a wide variety of peripherals such as a timer, synchronous serial port, successive approximation type 10-bit A/D converter, and voice output function. The nX-U8/100 CPU can execute instructions efficiently on a one-instruction-per-clock-pulse basis through parallel processing by the 3-stage pipelined architecture. The ROHM Semiconductor LAPIS ML610Q305 / ML610Q306 is also equipped with a Flash memory that has achieved low voltage and low power consumption (at read) equivalent to mask ROM, so it is well suited to battery-driven applications such as alarms and portable devices. In addition, it has an on-chip debugging function, which allows software debugging/rewriting with the LSI mounted on the board.
