DescriptionThe CXP913040 is a CMOS 16-bit microcomputer integrating on a single chip an A/D converter, serial interface with an incorporated buffer RAM, highprecision timing pattern generation function, pulse cycle measurement circuit, PWM generator, generalpurpose prescaler, vertical sync separation circuit, and a measurement circuit which measures the signals of capstan FG, drum FG/PG, reel FG and other servo systems with high precision, as well as basic configurations like a 16-bit CPU, ROM, RAM, and I/O port.
This LSI also provides sleep/stop modes CXP913040 that enable lower power consumption.
