Pin Assignment
The BL0507 is an infrared remote control transmitter LSI for TV,
VCR, stereo components, cassette decks, air conditioners, and other
appliances. There are 64 function keys and 3 double action keys, the
128+6 function codes are available by using SELECT terminal. The
transmission code consists of “leader pules”, “16bit customer code”, and
“16 bit date code”. Using micro-processors for decode, various
applications can be realized. (BL0507compatible with NEC standard
µPD 6122-G001)
