UPD178004A, 8-BIT SINGLE-CHIP MICROCONTROLLERS

DATA SHEET MOS INTEGRATED CIRCUIT µ PD178004A, 178006A, 178016A, 178018A 8-BIT SINGLE-CHIP MICROCONTROLLERS The µ PD178004A, 178006A, 178016A and 178018A 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 instructions, suitable for system control.
