PD17201A, 17207
4-BIT SINGLE-CHIP MICROCONTROLLER WITH
LCD CONTROLLER/DRIVER AND A/D CONVERTER
FOR INFRARED REMOTE CONTROL TRANSMITTERS
MOS INTEGRATED CIRCUIT
DESCRIPTION
The
碌
PD17201A, 17207 is a 4-bit single-chip microcontroller, used for infrared remote control transmitters, which
in-tegrates an LCD controller/driver, A/D converter, and remote controller carrier generator circuit on a single chip.
For the CPU, this microcontroller employs the 17K architecture of the general-purpose register method, and it can
directly execute operations between data memory addresses which would have been conventionally executed by an
accumulator. In addition, all the instructions are 16-bit, 1-word instructions, enabling efficient programming.
A one-time PROM model,
碌
PD17P207, to which data can be written only once is also available. This one-time
PROM model is useful for program evaluation of the
碌
PD17201A or 17207.
Detalied functionins are described in the following manual. Be sure to read this manual when designing
your system.
