Description

PCA8521 The 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. The oscillator frequency may be optionally chosen as 432 kHz or 4 MHz.For 432 kHz additional external capac
