Description
The CXP888P60 is a CMOS 8-bit micro-computer
which consists of A/D converter, serial interface,
timer/counter, time base timer, high precision timing
pattern generation circuits, PWM output, VISS/
VASS circuit, 32kHz timer/counter, remote control
receiving circuit, VSYNC separator and the
measurement circuit which measure signals of
capstan FG amplifier and drum FG/PG amplifier and
other servo systems, as well as basic configurations
like 8-bit CPU, PROM, RAM and I/O port. They are
integrated into a single chip.
Also, CXP888P60 provides sleep/stop function
which enables to lower power consumption.
The CXP888P60 is the PROM-incorporated
version of the CXP88860 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.
