8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
碌
PD178076, 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
碌
PD178076 and 178078 have an asynchronous serial interface (UART) mode, and the
碌
PD178096 and
178098 have an IEBus
TM
controller.
Moreover, a flash memory model, the
碌
PD178F098, that operates in the same supply voltage range as the mask
ROM models, and various development tools are also under development.
