MOS INTEGRATED CIRCUIT
PD17240,17241,17242,17243,17244,17245,17246
DESCRIPTION
The
PD17240, 17241, 17242, 17243, 17244, 17245, 17246 (hereafter called the PD17246 Subseries) are 4-
bit single-chip microcontrollers for small general-purpose infrared remote control transmitters.
This subseries employs 17K general-purpose register system architecture for the CPU, and can directly execute
operations between data memories instead of the conventional method of executing operations through an
accumulator. Moreover, all the instructions are 16-bit/1-word instructions, enabling efficient programming.
In addition, a one-time PROM model, the
PD17P246, to which data can be written only once, is also available.
This product is convenient either for evaluating the
PD17246 Subseries programs or for small-scale production of
application systems.
Detailed function descriptions are provided in the following user's manual. Be sure to read them before
designing.
