COP888xG/CS Family

8-Bit CMOS ROM Based Microcontrollers with 4k to 24k

Memory, Comparators and USART

General Description

Note: COP8SG devices are form-fit-function compatible su-

persets of the COP888xG/CL/CS Family devices, and are

replacements for these in new designs, and design up-

grades with minimum effort.

The COP888xG ROM based microcontrollers are highly inte-

grated COP8

to 24k) and advanced features including two Analog com-

parators. These single-chip CMOS devices are suited for

more complex applications requiring a full featured controller

with a range of memory sizes, low EMI (except EG), com-

parators, and a full-duplex USART. Pin and software com-

patible (different V
