Description
The CXP913P048 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 that enable lower power consumption.
The CXP913P048 is the PROM-incorporated version of the CXP913040 with built-in mask ROM. This provides the additional feature of being able to write directly into the program. Thus, it is most suitable for evaluation use during system development and for
small-quantity production.
