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 UART, melody driver, Analog compartor, and LCD driver. The CPU nX-U8/100 is capable of efficient instruction execution in 1-intruction 1-clock mode by 3-stage pipe line architecture parallel processing. 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. MTP version can rewrite programs on-board, which can contribute to reduction in product development TAT. The flash memory incorporated into this MTP version implements the mask ROM-equivalent low-voltage operation (1.25V or higher) and low-power consumption (typically 4.5uA at low-speed operation), enabling volume production by the MTP version.
