The µPD17P236 is a programmable integrated circuit that can be used to develop and produce remote controllers. It has 32K bytes of program memory and 223×4 bits of data memory. It also has a low-voltage detection circuit that can shut down the circuit when the voltage is below 3.0V.
The NEC uPD17P236 is a 4-bit single-chip microcontroller designed specifically for small general-purpose infrared remote controllers. It features a one-time programmable PROM (32 Kbytes) instead of an internal mask ROM, allowing users to write custom programs for experimental or small-scale production of remote control systems. The device is pin-compatible with the uPD17236 series and includes a carrier generator circuit for infrared transmission.
