DATA SHEET

MOS INTEGRATED CIRCUIT

µPD17145(A1), 17147(A1), 17149(A1)

SMALL, GENERAL-PURPOSE

4-BIT SINGLE-CHIP MICROCONTROLLERS

The µPD17145(A1), 17147(A1), and 17149(A1) are 4-bit single-chip microcontrollers integrating an 8-bit

A/D converter (4 channels), a timer function (3 channels), and a serial interface.

These microcontrollers employ a CPU of the general-purpose register type that can execute direct memory

operations and direct memory-to-memory data transfer for efficient programming. All the instructions consist

of 16 bits per word.

In addition, a one-time PROM version, the µPD17P149, is also available for program evaluation.

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

to read the following manual when designing your system:

µPD17145 Subseries User’s Manual: IEU-1383
