CXP87800

Piggyback/

CMOS 8-bit Single Chip Microcomputer

Description

The CXP87800 is a CMOS 8-bit single chip micro­computer of piggyback/evaluator combined type,
which is developed for evaluating the function of the
CXP87852/87860.

Features

• A wide instruction set (213 instructions) which

cover various types of data.

— 16-bit operation/multiplication and division/

boolean bit operation instructions

• Minimum instruction cycle 250ns at 16MHz operation (4.5 to 5.5V)

• Applicable EPROM LCC type 27C512

(Maximum 60K bytes are available.)

• Incorporated RAM capacity 2048 bytes

• Peripheral functions

8-bit and 8-stage FIFO 1 channel
(Auto transfer for 1 to 8 bytes)
Incorporated two-wire 8-bit and 8-stage FIFO 1 channel
(Auto transfer for 1 to 8 bytes)

— Timer 8-bit timer, 8-bit timer/counter

19-bit time base timer, 32kHz timer/counter

— High precision timing pattern generator PPG 19-pin, 32-stage programmable

RTG 5 pins, 2 channels

— PWM/DA gate output PWM output 12 bits, 2 channels

(Repetitive frequency of 62.5kHz/16MHz)
