PD178096A,178098A
8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The
碌
PD178096A and 178098A 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
PD178096A and 178098A 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.
Detailed function descriptions are provided in the following user鈥檚 manuals. Be sure to read them before
designing.
