UPD178003 Datasheet | NEC

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,...
