GENERAL DESCRIPTION
Equipped with a 8-bit CPU nX-U8/100, the ML610Q178 is a high-performance 8-bit CMOS microcontroller
that integrates a wide variety of peripherals such as 10-bit A/D converter, timer, PWM, synchronous serial port,
UART, I2C bus interface (master), Battery level detect circuit, LCD driver. The nX-U8/100 CPU is capable of
executing instructions efficiently on a one-instruction-per-clock-pulse basis through parallel processing by the
3-stage pipelined architecture.
In addition, it has an on-chip debugging function, which allows software debugging/rewriting with the LSI
mounted on the board.
