MOS INTEGRATED CIRCUIT

µPD178023,178024

8-BIT SINGLE-CHIP MICROCONTROLLER

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 under development.

For the detailed functional description, refer to the following User’s Manuals:
