DATA SHEET

DESCRIPTION

The

µPD178023, 178024 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, three serial interfaces, I2C bus (IIC0), three-wire (SIO3), and UART are provided.

Moreover, a flash memory model, the

µPD178F124, that operates in the same supply voltage range as the mask

ROM models, and various development tools are also available.
