Description

The CXP86540/86548/86560 are the CMOS 8-bit microcomputer integrating on a single chip an A/D converter, serial interface, timer/counter, time-base timer, on-screen display function, I2C bus interface, PWM output, remote control reception circuit, HSYNC counter, watchdog timer, 32kHz timer/counter besides the basic configurations of 8-bit CPU, ROM, RAM, I/O ports. The CXP86540/86548/86560 also provide a Sleep function that enables to lower the power consumption.
