1 / 72 page  © 1997, 2000 DATA SHEET 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. For the detailed functional description, refer to the following User’s Manuals: µPD178078, 178098 Subseries User’s Manual : U12790E 78K/0 Series User’s Manual - Instruction : U12326E FEATURES • High-capacity ROM and RAM Item Program Memory (ROM) Data Memory Part Number Internal high-speed RAM Internal buffer RAM Internal extension RAM µPD178076, 178096 48K bytes 1024 bytes 32 bytes 1024 bytes µPD178078, 178098 60K bytes 2048 bytes MOS INTEGRATED CIRCUIT µPD178076,178078,178096,178098 Document No. U12885EJ3V0DS00 Date Published June 2000 N CP(K) Printed in Japan 8-BIT SINGLE-CHIP MICROCONTROLLER • Instruction cycle: 0.32 µs (with crystal resonator of fX = 6.3 MHz) • Many internal hardware units General-purpose I/O ports, A/D converter, serial interface (UART mode: µPD178076 and 178078 only), IEBus controller ( µPD178096 and 178098 only), timers, frequency counter, power-ON clear circuit • Hardware for PLL frequency synthesizer dual modulus prescaler, programmable divider, phase comparator, charge pump • Vectored interrupt sources • µPD178076, 178078: 22 • µPD178096, 178098: 21 • Supply voltage :VDD = 4.5 to 5.5 V (during PLL and CPU operations) :VDD = 3.5 to 5.5 V (during CPU operation) The information in this document is subject to change without notice.
