The µPD178004A, 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. The instructions used are the high-speed 78K/0 instructions, suitable for system control. The rich assortment of 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 which can be operated in the same supply voltage range as for the mask ROM versions, and various development tools, are also available.
This document is a datasheet for the NEC uPD178004A, 178006A, 178016A, and 178018A, which are 8-bit single-chip CMOS microcontrollers designed for digital tuning systems. The devices utilize the 78K/0 architecture and include a rich assortment of peripheral hardware such as input/output ports, timers, A/D converters, and serial interfaces.
