4-BIT SINGLE-CHIP MICROCONTROLLER WITH LCD CONTROLLER/DRIVER AND A/D CONVERTER FOR INFRARED REMOTE CONTROL TRANSMITTERS
MOS INTEGRATED CIRCUIT
DESCRIPTION
The µPD17201A, 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, µPD17P207, to which data can be written only once is also available. This one-time PROM model is useful for program evaluation of the µPD17201A or 17207. Detalied functionins are described in the following manual. Be sure to read this manual when designing your system.
