8-BIT SINGLE-CHIP MICROCONTROLLER
The µPD178004, 178006, 178016 and 178018 are 8-bit single-chip CMOS microcontrollers that incorporate
hardware for digital tuning systems.
The CPU uses the 78K/0 architecture and high-speed access to internal memory and control of peripheral
hardware are easy to implement. Also, 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 µPD178P018, 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.
For more information on functions, refer to the following User’s Manuals. Be sure to read them when
designing.
