Overview
1.1
Features
This LSI is a high-performance 8-bit CMOS microcontroller into which rich peripheral circuits, such as synchronous
serial port, UART, I
2C bus interface (master), buzzer driver, battery level detect circuit, RC oscillation type A/D
converter, 12-bit successive approximation type A/D converter, and LCD driver, are incorporated around
8-bit CPU
nX-U8/100.
The CPU nX-U8/100 is capable of efficient instruction execution in 1-intruction 1-clock mode by 3-stage pipe line
architecture parallel procesing. The Flash ROM that is installed as program memory achieves low-voltage low-power
consumption operation (read operation) equivalent to mask ROM and is most suitable for battery-driven applications.
The on-chip debug function that is installed enables program debugging and programming.
