UPD178003

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 instructions, suitable for system control. The peripheral hardware includes an input/output port, 8-bit timer, A/D converter, serial interface, power-on-clear circuits, as well as a pre-scaler for digital tuning, a PLL frequency synthesizer, and a frequency counter. The µPD178P018A, one-time PROM or EPROM versions that can be operated in the same supply voltage range as for the mask ROM versions, and various development tools, are also available. Detailed function descriptions are provided in the following user’s manuals.
