DESCRIPTION
μ
PD17230, 17231, 17232, 17233, 17234, 17235, 17236 (hereafter called
μ
PD17236 subseries) are 4-bit single-
chip microcontrollers for small general-purpose infrared remote control transmitters.
It employs a 17K architecture of general-purpose register type devices for the CPU, and can directly execute
operations between memories instead of the conventional method of executing operations through the accumulator.
Moreover, all the instructions are 16-bit 1-word instructions which can be programmed efficiently.
In addition, a one-time PROM model,
μ
PD17P236
Note
, to which data can be written only once, is also available.
It is convenient either for evaluating the
μ
PD17236 subseries programs or small-scale production of application
systems.
Note
Under development
Detailed functions are described in the following manual. Be sure to read this manual when designing your
system.
