MICROCOMPUTER/MICROPROCESSOR (MCU/MPU)
The MC6801 U4 is an 8-bit single-chip microcomputer unit (MCU)
which enhances the capabilities of the MC6801 and significantly
enhances the capabilities of the M6800 Family of parts. It includes an
MC6801 microprocessor unit (MPU) with direct object-code com-
patibility and upward object-code compatibility with the MCWOO. Ex-
ecution times of key instructions have been improved over the MC6BO0
and the new instructions found on the MC6801 are included. The MCU
can function as a monolithic microcomputer or can be expanded to a
64K byte address space. It is TTL compatible and requires one + 5-volt
power supply. On-chip resources include 4096 bytes of ROM, 192 bytes
of RAM, a serial communications interface (SCI), parallel 1/0, and a ~
16-bit six-function programmable timer. The MC6803U4 can be con- ~~~
sidered an MC6801 U4 operating in modes 2 or 3; i.e., those that do n~$ ‘t+
