DATA SHEET µPD178023,178024 8-BIT SINGLE-CHIP MICROCONTROLLER MOS INTEGRATED CIRCUIT 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.
