UPD178002 Description
DATA SHEET MOS INTEGRATED CIRCUIT µ PD178002, 178003 8-BIT SINGLE-CHIP MICROCONTROLLERS The µPD178002 and 178003 are 8-bit single-chip CMOS microcontrollers that incorporate hardware for digital tuning systems. The CPU uses the 78K/0 architecture, which makes it easy to implement high-speed access to internal memory and control of peripheral hardware. Also, the instructions used are the high-speed 78K/0...
