PRELIMINARY PRODUCT INFORMATION

MOS INTEGRATED CIRCUIT

µPD178046, 178048

8-BIT SINGLE-CHIP MICROCONTROLLER

DESCRIPTION

The µPD178046 and 178048 are 8-bit single-chip CMOS microcontrollers with hardware for digital tuning systems.

Employing the 78K/0 architecture as the CPU, these microcontrollers provide easy control access to the internal

memories and peripheral hardware. The instructions are high-speed 78K/0 instructions suitable for system control.

As the peripheral hardware, an OSD (on-screen display) controller and PWM (pulse width modulation) output for

TV use, as well as many I/O ports, timers, A/D converter, serial interface, and power-ON clear circuit are provided.

A flash memory model, µPD178F048, that can operate on the same supply voltage as the mask ROM models, and

many development tools are under development.

The functions of these microcontrollers are described in detail in the following User’s Manuals. Be sure

to read these manuals when you design your system.
