SMALL, GENERAL-PURPOSE
4-BIT SINGLE-CHIP MICROCONTROLLERS
μ
PD17145(A1), 17147(A1), 17149(A1)
The
μ
PD17145(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
μ
PD17P149, 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:
