MOS INTEGRATED CIRCUIT
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.
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
μ
PD178P018A, 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.
