Description
The M16C/6K9 group of single-chip microcomputers are built using the high-performance silicon gate
CMOS process using a M16C/60 Series CPU core and are packaged in a 144-pin plastic molded QFP.
These single-chip microcomputers operate using sophisticated instructions featuring a high level of instruc-
tion efficiency. To communicate with host CPU, the LPC bus interface is built in. In this way, this MCU can
work as slave controller in the personal computer system.
The specification is target oriented specification for the development of M16C/6K9.
