COMMENTS

Compatible versions of the single chip microcomputers pro· vide mask programmed, light erasable, or no internal program memory.

Compatible devices allow direct expansion of MCS-48 functions with no additional external com· ponents.

Low cost I/O expander.

Allows low cost external expan· sion of Program Memory. Each ROM is interchangeable with an

EPROM.

User programmable and eras· able.

Data memory can be easily ex· panded using standard NMOS RAMs.

Serves as Address Latch or I/O port.

Three 8-bit programmable 110 ports.

Serial Communications Receiv· er/Transmitters.
