MOS INTEGRATED CIRCUIT
µPD178076,178078,178096,178098
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD178076, 178078, 178096, and 178098 are 8-bit single-chip CMOS microcontrollers containing hardware
for digital tuning systems.
These microcontrollers employ a 78K/0 series architecture CPU and allow easy access to internal memories at
high speed and easy control of peripheral hardware units. The high-speed 78K/0 series instructions are ideal for
system control.
As peripheral hardware, a prescaler, PLL frequency synthesizer, and frequency counter for digital tuning systems
are provided, as well as many I/O ports, timers, A/D converter, serial interface, and a power-ON clear circuit. In
addition, the µPD178076 and 178078 have an asynchronous serial interface (UART) mode, and the µPD178096 and
178098 have an IEBusTM controller.
Moreover, a flash memory model, the µPD178F098, that operates in the same supply voltage range as the mask
ROM models, and various development tools are also under development.
For the detailed functional description, refer to the following User’s Manuals:
