This LSI family is a high-performance 16-bit CMOS microcontroller into which rich peripheral circuits, such as synchronous serial port, UART, I2 C bus interface (master), supply voltage level detect circuit, RC oscillation type A/D converter, and successive approximation type A/D converter are incorporated around 16-bit CPU nX-U16/100. The CPU nX-U16/100 is capable of efficient instruction execution in 1-instruction 1-clock mode by 3-stage pipe line architecture parallel processing. The Flash ROM that is installed as program memory achieves low-voltage low-power consumption operation (read operation) is most suitable for battery-driven applications. And, this LSI has a data flash-memory fill area by a software which can be written in. The on-chip debug function that is installed enables program debugging and programming.
