GENERAL DESCRIPTION\nThe PCA8521 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. An example of an application diagram using a 20-pin IC is illustrated in Fig.7.FEATURES\n? RC5 protocol\n? Maximum of:\n– 56 keys (20-pin version)\n– 30 keys (16-pin version).\n?
