DATA SHEET 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.
