GENERAL DESCRIPTION
This LSI is a high performance CMOS 8-bit microcontroller equipped with an 8-bit CPU nX-U8/100 and integrated with
peripheral functions such as the synchronous serial port, UART, melody driver, RC oscillation type A/D converter, and LCD
driver.
The CPU nX-U8/100 is capable of efficient instruction execution in 1-instruction 1-clock mode by 3-stage pipe line architecture
parallel procesing. Additionally, it adopts the low-/high-speed dual clock system, standby mode, and process that prohibits leak
current at high temperatures, and is most suitable for battery-driven applications.
Flash version can rewrite programs on-board, which can contribute to reduction in product development TAT. The flash
memory incorporated into this Flash version implements the mask ROM-equivalent low-voltage operation and low-power
consumption, enabling volume production by the Flash version.
