DATA SHEET
DESCRIPTION
The
μ
PD178023, 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, I
2
C bus (IIC0), three-wire (SIO3), and UART are provided.
Moreover, a flash memory model, the
μ
PD178F124, 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:
