DESCRIPTION

The

µPD780016Y and 780018Y are members of the µPD780018Y subseries of the 78K/0 series microcontrollers.

Besides a high-speed, high-performance CPU, these microcontrollers have on-chip ROM, RAM, I/O ports, timer,

serial interface, real-time output port, interrupt control, and various other peripheral hardware.

The

µPD78P0018Y devices including a one-time PROM version and an EPROM version, both of which can operate

in the same power supply voltage range as a mask ROM version, and various development tools are available.

The details of the functions are described in the following user’s manuals. Be sure to read it before starting design.
