Description
The CXP87132/87140 is a CMOS 8-bit microcomputer
which consists of A/D converter, serial interface (2ch
independently), timer/counter, time base timer, vector
interruption, high precision timing pattern generation
circuit (PPG 2ch independently, RTG 2ch independently),
PWM generator, general purpose prescaler, PWM for
tuner, VCR vertical sync separation circuit and the
measuring circuit which measure signals of capstan
FG and drum FG/PG and other servo systems, as
well as basic configurations like 8-bit CPU, ROM,
RAM and I/O port. They are integrated into a single
chip.
Also the CXP87132/87140 provides power on reset
function, sleep/stop function which enables to lower
power consumption.
