CXP85220A/85224A/85228A/85232A
CMOS 8-bit Single-chip Microcomputer
Description
The CXP85112B/85116B, CXP85220A/85224A/
85228A/85232A is a CMOS 8-bit single chip
microcomputer integrating on a single chip an A/D
converter, serial interface, timer/counter, time base
timer, vector interruption, on-screen display function,
I
2
C bus interface, PWM generator, remote control
reception circuit, HSYNC counter, power source
frequency counter and watch dog timer besides the
basic configurations of 8-bit CPU, ROM, RAM, and
l/O port.
The CXP85112B/85116B, CXP85220A/85224A/
85228A/85232A also provides a power-on reset
function and a sleep function that enables lower
power consumption.
