SC8521 Datasheet (Silan Microelectronics) - INFRARED REMOTE CONTROL TRANSMITTER

SC8521, INFRARED REMOTE CONTROL TRANSMITTER

The SC8521 can be used in infrared remote control transmitters.

It generates output pulses, in accordance with the RC5 protocol, when a key is pressed.

The IC does not contain a software programmable processor.

However, it does contain a ROM in which the codes that have to be transmitted are stored
