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.
