... SO20 plastic small outline package; 20 leads; body width 7.5 mm 1999 Jun 15 GENERAL DESCRIPTION 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 ...

... It is not possible to use a combination of jumper wires and selection keys for bank selection in one unit. The output of the ROM is loaded into a shift register that provides the input bits for the pulse generator. This pulse generator drives the output pin. 6 Product specification PCA8521 SN3 SN4 ...
