8-BIT SINGLE-CHIP MICROCONTROLLER

DESCRIPTION

The

PD178076, 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

PD178076 and 178078 have an asynchronous serial interface (UART) mode, and the

PD178096 and

178098 have an IEBus

controller.

Moreover, a flash memory model, the

PD178F098, 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:
