DATA SHEET  
MOS INTEGRATED CIRCUIT  
µPD78081, 78082  
8-BIT SINGLE-CHIP MICROCONTROLLER  
DESCRIPTION  
The µPD78081, 78082 are members of the µPD78083 subseries of the 78K/0 series microcontrollers.  
Besides a high-speed, high-performance CPU, these microcontrollers have on-chip ROM, RAM, I/O ports, 8-bit  
resolution A/D converter, timer, serial interface interrupt control, and other peripheral hardware.  
The µPD78P083 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.
