Description
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)

Function description
•
Oscillation Pin:
The BL0507 Oscillation circuit is designed for use of a
400kHz to 500kHz ceramic resonator, but there may be
mutual influence between variations in the IC and the
ceramic resonator resulting in abnormal oscillation. The
following table shows the recommended values of C
1
and
C
2
when using the BL0507.The oscillation circuit starts to
operate when a key is depressed.

Output the transmission code consisting of the leader code ,custom code
(16bits) and data code (16bits) .
DATA CODE D
7
can be controlled by this pin, allowing 128 kinds of data to be
transmitted. D
7
is set to “0” by connecting the pin to V
DD
, and to “1” by
connecting the SEL pin to V
SS
. As the input of this pin is high-impedance, it must
be connected to either V
DD
or Vss.
The custom code can be set by the diode connected to the CCS pin and the KI/O
pin.
Outputs “L” while the REM pin is outputting a transmission code.
Transmission Code
The transmission code consists of a leader code, 16-bit custom code, and 8-bit data code+8-bit inverse code of
the data code, they are also sent simultaneously, giving a total configuration of 32- bits per transmission. The
code uses the PPM (pulse position Modulation) method, with “1” and “0” differentiated by the time between
pulse. Each code consists of 8-bits, and simultaneous transmission of the inverse code allows configuration of a
system with an extremely low error rate.
