BL0509/BL0510
General Infrared Ray Remote Control Receiver
Description
The BL0509/0510 is CMOS LSI designed for use on the general infrared ray remote control receiver, and
when it is used in combination with BL9148, the remote control system can be constructed.
The BL0509 is DIP 16 Pin type and is capable of controlling 10 functions, while the BL0510 is DIP 24 PIN
type and is capable of controlling 18 functions. Except these, the principle and the block diagram of the two
circuits are almost the same.

Features
・High
anti-interference: excellent capability to anti-interfere, such as fluorescent lamp’s ballast, television,
etc. No error-code can be output.
・When
power on reset period, on pulse can be output from all ports and mal-operation can’t be happened
・
Able to output multiple keying signals parallel sent from the BL9148.(The BL0509 is able to output parallel
up to 5functions,while the BL0510 is up to 6 functions)
・Single
pulse, continuous pulse and cyclic pulse outputs are provided,(Cyclic pulse is available only for
BL0510)
・A
single terminal type oscillator by means of CR is provided
・Code
detection circuit provided for code check with the transmitter preventing interference’s form other
types.
Applications
Use as remote control transmitters in audios, air conditioners, toys and others.
