ROHM Semiconductor LAPIS ML610Q327/ML610Q338/ML610Q339 8-Bit MCUs

ROHM Semiconductor LAPIS ML610Q327/ML610Q338/ML610Q339 8-Bit Microcontrollers (MCUs) are high-performance 8-bit CMOS MCUs that integrate a wide variety of peripherals such as timer, PWM, UART, I2C bus interface, 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 ML610Q327 / ML610Q338 / ML610Q339 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 alarm and portable devices. In addition, it has an on-chip debugging function, which allows software debugging/rewriting with the LSI mounted on the board.
