16/8-BIT SINGLE-CHIP MICROCONTROLLERS
DESCRIPTION
The
m
PD784225 is a 80-pin general-purpose microcontroller which is function limited version of the
m
PD784216
with an added ROM correction function.
Flash memory versions, such as
m
PD78F4225, that can operate in the same voltage range as the mask ROM
version, and various development tools are under development.
The functions are explained in detail in the following user’s manuals. Be sure to read this manual when
designing your system.
