Description

The BL0508A1 is an infrared remote control transmitter LSI. There are 32 function keys and 3 double action keys . The transmission code consists of “leader pulse”, “16bit customer code ”and “16 bit date ”. Using microprocessors for decode, various applications can be realized. (BL0508A1 is compatible with LC7462)

Features

• Low voltage operation: VDD=2.0~3.3V

• Low power consumption: IDD≤ 1μ A at standby mode

• A system with high interference resistance and an extremely low error rate .

• Fewer external parts

• Use of ceramic resonator with a 400 to 500kHz oscillation is designed for non-adjustment operation

Applications:

Remote Control for TV
