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,

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.
