Famicom remote controller

Yesterday, I walked around flea market and found a set of famicom remote controller and I disassemble the infrared receiver and control pad.What a pity is that the IC has been grinded and can not get the code.

发一个关于早年瑞昱半导体生产的RTS702 RTS703红白机专用无线手柄编码译码IC资料

因为本人英文水平有限,只能看得懂但不会写,所以只能把一些近来研究的硬件资料发到中文板块了。上个月偶得一套配有红外手柄的胜天9900型号的FC兼容机,无线手柄接收器与主机一体化设计,且无线手柄具有1P/2P的切换功能。拆开一看,发现主机内部和无线手柄内部均是台湾螃蟹的IC,型号为RTS702与RTS703。上网查阅早年资料得知,RTS702与RTS703是上世纪90年代初瑞昱半导体专为无线手柄设计的9路编码译码IC,原理图及各引脚功能分别如下。其中RTS703为编码IC,702为译码IC。 mxcp13080716086657.jpg mxcp13080716126931.jpg mxcp130...

Re: Weird famiclone with infrared controllers

The UA6581 chip is used to decode the remote controller infrared signal and in the remote controller is UA6580 to encode and transmit signal.This remote controller can switch 1P/2P and when you press SELECT + A button ,the console will reset.Both of the chip are created and manufactured by UMC(联华半导体...
